What is long division method?

Long division is a mathematical method used to divide one number by another. It is typically used for division of larger numbers, and is taught as a basic arithmetic skill in elementary and middle school.

In long division, the dividend (the number being divided) is written on the top, and the divisor (the number dividing the dividend) is written on the left. The quotient (the answer to the division problem) is written on the top of the line below the dividend, with the remainder (the left-over amount after division) written on the right.

The process involves a series of steps, including dividing, multiplying, and subtracting. The steps are repeated until the dividend is fully divided, or until a specified level of precision is reached.

Long division is also used to divide polynomials, by using the coefficients of the terms in the polynomial instead of the actual numbers. This process is similar to long division of numbers, but involves additional steps to ensure that the division is performed correctly.

Now We want to divide the polynomial [tex]4x^4 - 5x^3 + 2x^2 - x + 5[/tex] by the polynomial [tex]x^2 + x + 1[/tex] using long division.

[tex]x^2 + x + 1 |[/tex] ([tex]4x^4 - 5x^3 + 2x^2 - x + 5[/tex] )

First, we divide the highest degree term of the dividend, [tex]4x^4[/tex], by the highest degree term of the divisor, [tex]x^2[/tex], to get [tex]4x^2[/tex] :

[tex]x^2 + x + 1 | 4x^4 - 5x^3 + 2x^2 - x + 5\\-4x^4 - 4x^3 - 4x^2\\-----------------------------\\x^3 + 2x^2[/tex]

Next, we multiply the divisor,[tex]x^2 + x + 1[/tex], by the quotient, [tex]4x^2[/tex], to get [tex]4x^4 + 4x^3 + 4x^2[/tex], and subtract it from the dividend:

[tex]x^2 + x + 1 | 4x^4 - 5x^3 + 2x^2 - x + 5\\-4x^4 - 4x^3 - 4x^2\\----------\\x^3 + 2x^2\\- 4x^2 - 4x - 4\\-------\\3x^2 - x + 5[/tex]

We now have a new polynomial, 3[tex]x^2 - x + 5[/tex], as the remainder. Since the degree of the remainder is less than the degree of the divisor, the division process is complete.

Therefore, the quotient is [tex]4x^2[/tex] and the remainder is [tex]3x^2 - x + 5[/tex]. We can write the original polynomial as:

[tex]4x^4 - 5x^3 + 2x^2 - x + 5 = (x^2 + x + 1)(4x^2) + (3x^2 - x + 5)[/tex]

After how many minutes will the two pools have the same amount of water?
How much water will be in each pool when they have the same amount?

Answers

It will take 16.84 minutes for the two pools to have the same amount of water and when the two pools have the same amount of water, each pool will have 385.84 liters of water.

The amount of water in the first pool is 770 liters, since no water is being added to it.

The amount of water in the second pool is 45.75t liters, since water is being added to it at a rate of 45.75 liters per minute.

To find the time at which the two pools have the same amount of water, we can set these two expressions equal to each other and solve for t:

770 = 45.75t

t = 770 / 45.75

t = 16.84 minutes

So it will take approximately 16.84 minutes for the two pools to have the same amount of water.

To find the amount of water in each pool when they have the same amount, we can substitute t = 16.84 into either expression.

Using the expression for the second pool, we have:

Amount of water in second pool = 45.75t

= 45.75(16.84)

= 771.69 liters

Therefore, when the two pools have the same amount of water, each pool will have 771.69 / 2 = 385.84 liters of water.

Because simple interest is used on short-term notes, the time period is often given in days rather than months or years. We convert this to years by dividing by 360, assuming a 360 day year called a banker's year.

T-bills (Treasury bills) are one of the instruments the U.S. Treasury Department uses to finance public debt. If you buy a 260-day T-bill with a maturity value of $12,750 for $12,401.35, what annual simple interest rate will you earn? Express your answer as a percentage.

%. Round to the nearest thousandths of a percent (3 decimal places).

Answers

The yearly simple interest rate on the T-bill is 5.01%.

How to calculate the simple interest?

The simple interest formula is:

Principal x Rate x Time = Interest

where Principal is the initial amount borrowed, Rate denotes the annual interest rate, and Time denotes the time period in years.

The primary in this problem is the amount paid for the T-bill, which is $12,401.35. The maturity value is not taken into account in the calculation.

The time span is expressed as 260 days or 260/360 of a year. (using the assumption of a 360-day year). Therefore,

Time is equal to 260/360 = 0.7222 years.

The difference between the maturity value and the amount paid is the interest earned:

$12,750 - $12,401.35 = $348.65 in interest

We can now calculate the annual interest rate:

Interest Rate = $348.65 / $12,401.35 / 0.7222 = 0.0501

We multiply to get a percentage by 100:

Rate = 5.01%

As a result, the yearly simple interest rate on the T-bill is 5.01%.

The amount of laps remaining, y, in a swimmer's race after x minutes can be represented by the graph shown.

coordinate grid with the x axis labeled time in minutes and the y axis labeled number of laps remaining with a line from 0 comma 24 and 6 comma 0

Determine the slope of the line and explain its meaning in terms of the real-world scenario.

The slope of the line is 6, which means that the swimmer will finish the race after 6 minutes.
The slope of the line is 24, which means that the swimmer must complete 24 laps in the race.
The slope of the line is −4, which means that the swimmer will complete 4 laps every minute.
The slope of the line is negative one fourth, which means that the swimmer completes a lap in one fourth of a minute.

Answers

The slope of the line is -4 which represents the swimmer will complete 4 laps per minute.

In real world scenario it means how many laps they can complete per minute.

Let us consider the coordinate on the y-axis and the x-axis be ,

( x₁ , y₁ ) = ( 0, 24 )

( x₂ , y₂ ) = ( 6, 0)

The slope of a line represents the rate of change between two variables.

Here, the slope of the line represents the rate at which the number of laps remaining changes with respect to time.

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

         = ( 0 - 24 ) / ( 6 - 0 )

         = -4

Since the slope of the line is -4, this means that for every one minute that passes.

The swimmer completes 4 laps since the slope is negative, the number of laps remaining decreases as time increases.

So in this scenario, the slope of the line tells us that the swimmer is completing laps at a rate of 4 laps per minute.

And that they will finish the race after 6 minutes when they have completed all 24 laps.

Therefore, slope of line is -4 represents the swimmer's lap completion rate which means swimmer will complete 4 laps every minute.

Solve Systems of Equation using Laplace:
X' = -Y
Y' = X - Y

X(0) = 1 Y(0) = 2

Answers

The solutions to the system of equations X' = -Y , Y' = X - Y using Laplace transform is given by X(t) = -1 , and Y(t) = -1 + e^t.

Systems of Equation are,

X' = -Y

Y' = X - Y

X(0) = 1

Y(0) = 2

System of equations using Laplace transforms,

First need to take the Laplace transform of both equations .

and then solve for the Laplace transforms of X(s) and Y(s).

Taking the Laplace transform of the first equation, we get,

sX(s) - x(0) = -Y(s)

Substituting in the initial condition X(0) = 1, we get,

sX(s) - 1 = -Y(s) (1)

Taking the Laplace transform of the second equation, we get.

sY(s) - y(0) = X(s) - Y(s)

Substituting in the initial condition Y(0) = 2, we get,

sY(s) - 2 = X(s) - Y(s) (2)

Eliminate X(s) from these equations by adding equations (1) and (2),

sX(s) - 1 + sY(s) - 2 = -Y(s) + X(s) - Y(s)

Simplifying, we get,

sX(s) + sY(s) = Y(s) + X(s) - 1

Using  X(s) = sY(s) - Y(s) from the first equation, substitute to get.

s(sY(s) - Y(s)) + sY(s) = Y(s) + (sY(s) - Y(s)) - 1

Expanding and simplifying, we get,

s²Y(s) - sY(s) + sY(s) = Y(s) + sY(s) - Y(s) - 1

Simplifying further, we get,

s² Y(s) = sY(s) - 1

⇒Y(s) (s -s² ) = 1

⇒Y(s) = -1 / s(s-1)

Dividing by s², we get,

Y(s) = -1 /(s(s-1)

Using the fact that X(s) = sY(s) - Y(s) from the first equation, we can substitute to get:

X(s) = s(-1 /(s(s-1)) +1/s(s-1)

Simplifying, we get

X(s) = -1/(s -1) + 1/s(s-1)

⇒X(s) = - (s-1) / s(s -1)

⇒X(s) =  -1/ s

Now we can take the inverse Laplace transform of X(s) and Y(s) to get the solutions to the original system of equations:

L⁻¹{-1/s} = -1

L⁻¹{-1/(s(s-1))} = -1 + e^t

Therefore, the solutions to the system of differential equations using Laplace transform are equals to X(t) = -1 , and Y(t) = -1 + e^t.

Country Day's scholarship fund receives a gift of $ 135000. The money is invested in stocks, bonds, and CDs. CDs pay 3.75 % interest, bonds pay 3.5 % interest, and stocks pay 9.7 % interest. Country day invests $ 60000 more in bonds than in CDs. If the annual income from the investments is $ 6337.5 , how much was invested in each vehicle

Answers

Step-by-step explanation:

Let X be the amount invested in CDs, Y be the amount invested in bonds, and Z be the amount invested in stocks.

We know from the problem that:

X + Y + Z = 135000 ---(1) (the total amount invested is $135000)

0.0375X + 0.035Y + 0.097Z = 6337.5 ---(2) (the total annual income from the investments is $6337.5)

Y = X + 60000 ---(3) (the amount invested in bonds is $60000 more than the amount invested in CDs)

We can use equation (3) to substitute for Y in equations (1) and (2), then solve for X and Z as follows:

X + (X + 60000) + Z = 135000

2X + Z = 75000

0.0375X + 0.035(X + 60000) + 0.097Z = 6337.5

0.0725X + 0.097Z = 8550

Using the system of equations 2X + Z = 75000 and 0.0725X + 0.097Z = 8550, we can solve for X and Z to get:

X = 22500

Z = 78000

Substituting back into equation (3), we get:

Y = X + 60000 = 82500

Therefore, the amounts invested in CDs, bonds, and stocks were $22500, $82500, and $78000 respectively.

A) The monthly payment (PMT) for the loan is $-244.13.

B) The total interest for the loan is $1,718.20 (rounded to the nearest cent).

How to calculate the monthly payments and the total interest for the loan?

To find the monthly payments (PMT) and the total interest for the loan, we use the formula for calculating the PMT for a loan with a fixed interest rate, known as the Amortizing Loan Payment Formula:

PMT = P × r × (1 + r)^n / ((1 + r)^n - 1)

Where:

PMT = Monthly payment

P = Principal amount (loan amount)

r = Monthly interest rate (annual interest rate divided by 12)

n = Number of months in the loan term

Given:

No of periods = 48

Principal amount (P) = $10,000

Annual interest rate = 8%

Loan term = 4 years

First, let's calculate the monthly interest rate (r):

r = Annual interest rate / 12 months

r = 8% / 12

r = 0.08 / 12

r = 0.00667 (rounded to 5 decimal places)

Next, we calculate the number of months in the loan term (n):

n = Loan term in years × 12 months/year

n = 4 years × 12

n = 48

Let's put the values into the formula to calculate the monthly payment (PMT):

PMT = $10,000 × 0.00667 × (1 + 0.00667)^48 / ((1 + 0.00667)^48 - 1)

PMT = $-244.13 (rounded to the nearest cent)

B) To calculate the total interest, we can multiply the monthly payment by the number of months in the loan term, and then subtract the principal amount:

Total interest = (PMT × n) - P

Total interest = ($157.08 × 48) - $10,000

Total interest = $1,718.20

Thus, the total interest for the loan is  $1,718.20 (rounded to the nearest cent).

If the vertex of the graph of the quadratic function is a parentheses four, 19 parentheses, what is the value of v

Answers

Therefore, the point (v, w) = (x, y) = (6, 15)

How to solve

The diagram above has two graphs (ABC and DE) intercepting at a point, (v, w).

To find the interception point (v, w), we need to first find the equations of each graph, with ABC being a parabola and DE, a straight line.

Since ABC is a parabola and the vertex is given, the standard vertex form of a parabola is given by:

y = a(x – h)2 + k ----------- eqn(1)

where (h, k) is the vertex of the parabola (the vertex is the point where the parabola changes direction) and "a" is a constant that tells whether the parabola opens up or down (negative indicates downward and positive indicates upward).

Given vertex (4, 19), eqn(1) becomes:

y = a(x - 4)2 + 19 -------------- eqn(2)

Since the parabola passes through point (0, 3), that is, x = 0 and y = 3,

we substitute the value of x and y into eqn(2) to find the value of "a"

3 = a(0 - 4)2 + 19

3 = a(-4)2 + 19

3 = 16a + 19

16a = 3 - 19

16a = -16

a = -1

Thus, eqn(2) becomes:

y = -(x - 4)2 + 19 ------------- eqn(3)

Next, we find the equation of DE (straight line).

Since DE is a straight line and the general form of straight-line equation is given by:

y = mx + c ------------------ eqn(4)

where m is the slope and c is the point at which the graph intercepts the y-axis.

c = -9

m = (y2 - y1) / (x2 - x1)

At points (0, -9) and (2, -1)

x1 = 0

x2 = 2

y1 = -9

y2 = -1

m = (-1 - (-9)) / (2 - 0)

= (-1 + 9)/2

= 8/2

m = 4

Substitute the values of m and c into eqn(4)

y = 4x - 9 ---------------- eqn(5)

Since point (v, w) is the point where both graphs meet,

eqn(3) = eqn(5)

-(x - 4)2 + 19 = 4x - 9

-[(x - 4)(x - 4)] + 19 = 4x - 9

-(x2 - 8x + 16) + 19 = 4x - 9

-x2 + 8x - 16 + 19 = 4x - 9

-x2 + 8x - 4x - 16 + 19 + 9 = 0

-x2 + 4x + 12 = 0

multiply through with -1

x2 - 4x - 12 = 0 ----------- eqn(6)

The above is a quadratic equation and can be simplified either by factorization, completing the square, or quadratic formula method.

Using the factorization method,

product of roots = -12

sum of roots = -4

Next, find two numbers whose sum is equal to the sum of roots (-4) and whose product is equal to the product of roots (-12)

Let the two numbers be 2 and -6

Replace the sum of roots (-4) in eqn(6) with the two numbers

x2 - 6x + 2x - 12 = 0

Group into two terms

(x2 - 6x) + (2x - 12) = 0

factorize each term

x(x - 6) + 2(x - 6) = 0

Pick and group the two values outside each bracket and inside one of the brackets

(x + 2) (x - 6) = 0

x + 2 = 0 and x - 6 = 0

x = -2 and x = 6

Since the point, (v, w) is on the right side of the y-axis, it follows that x cannot be –2. Therefore, x = 6.

substitute the value of x into eqn(5)

y = 4(6) - 9

y = 24 - 9

y = 15

Therefore, the point (v, w) = (x, y) = (6, 15)

A bag contains five ​batteries, all of which are the same size and are equally likely to be selected. Each battery is a different brand. If you select two batteries at​ random, use the counting principle to determine how many points will be in the sample space if the batteries are selected ​a) with replacement. ​b) without replacement.

Answers

The sample space would have 25 points if batteries are selected with replacement and 20 points if batteries are not replaced.

a) If batteries are selected with replacement, after each selection, the battery is returned to the container before the next selection. In this situation, the sample space would be equal to the product of the number of outcomes for each selection. Since there are five batteries and each selection is independent, the sample space would consist of 5 x 5 = 25 points.

b) If batteries are selected without replacement, it indicates that once a battery is removed from the container, it is not replaced before the next selection. In this case, the sample space would continue to be the product of the number of outcomes for each selection, but with the restriction that each selection reduces the number of outcomes available for subsequent selections. There are five options for the first option. For the second option, only four alternatives remain. The sample space would therefore be 5 × 4 = 20 points.

Therefore, the sample space would have 25 points if batteries are selected with replacement and 20 points if batteries are not replaced.

Rob and Ashley are riding their bicycles uphill. Currently, Rob is 5.7 km from the top and climbing at 0.24 km/min. Ashley is 4.5 km from the top and riding at 0.17 km/min. Estimate when Rob will be closer to the top than Ashley​

Answers

After approximately 17.14 minutes, Rob will be closer to the top than Ashley.

How to solve the problem

Rob's distance from the top = 5.7 - 0.24t

Ashley's distance from the top = 4.5 - 0.17t

We want to find the time t when Rob's distance from the top is less than Ashley's distance:

5.7 - 0.24t < 4.5 - 0.17t

Now, we'll isolate the t variable by adding 0.17t to both sides and subtracting 4.5 from both sides:

0.07t > 1.2

t > 1.2 / 0.07

t > 17.14

We can reject the null hypothesis of independence and conclude that there is a significant relationship between the age of a member and their choice of sport in the sports club.

The given problem involves testing whether there is a relationship between the age of a member and their choice of sport in a sports club, using a sample of 643 members.

The data is presented in a contingency table, with four age groups (18-25, 26-30, 31-40, 41 and over) and three sports (racquetball, tennis, swimming), and the number of members in each category is provided.

To test for independence, we can use a chi-square test of independence. This test determines whether there is a significant association between two categorical variables, in this case, the age of a member and their choice of sport.

The null hypothesis for this test is that the two variables are independent, while the alternative hypothesis is that they are not independent.

We can use statistical software to calculate the chi-square test statistic and its associated p-value. If the p-value is less than our chosen level of significance (usually 0.05), we can reject the null hypothesis and conclude that there is a significant relationship between the variables.

In this case, the chi-square test statistic is calculated as 47.125 with 6 degrees of freedom, and the associated p-value is less than 0.001. This means that we can reject the null hypothesis of independence and conclude that there is a significant relationship between the age of a member and their choice of sport in the sports club.

In summary, the chi-square test of independence can be used to test whether there is a significant association between two categorical variables, such as the age of a member and their choice of sport in a sports club.

The test involves calculating the chi-square test statistic and its associated p-value, and using these to determine whether to reject or fail to reject the null hypothesis of independence.

1. The two vectors parallel to the plane: Vector AB = (8, -5, 4) and Vector AC = (0, 7, 6)

2. The vector perpendicular to the plane is (-58, -48, 56).

How do we calculate for vectors parallel and perpendicular to the plane?

To find the vectors  parallel to the plane, we begin by finding the vectors AB and AC.

Vector AB = B - A = (11 - 3, -5 - 0, 2 - (-2)) = (8, -5, 4)

Vector AC = C - A = (3 - 3, 7 - 0, 4 - (-2)) = (0, 7, 6)

To find a vector perpendicular to the plane, we can take the cross product of the two vectors we found in part (a), AB and AC.

AB × AC = (AB_y * AC_z - AB_z * AC_y, AB_z * AC_x - AB_x * AC_z, AB_x * AC_y - AB_y * AC_x)

If we insert the figures, it will be

= ((-5) x 6 - 4 x 7, 4 x 0 - 8 x 6, 8 x 7 - (-5) x 0)

= (-30 - 28, -48, 56)

= (-58, -48, 56)

Consider the plane determined by the points A(3, 0, -2), B(11, -5, 2) and C(3, 7, 4).

What is a Positive Association?

In mathematics, a positive association refers to a relationship between two variables where an increase in the value of one variable is accompanied by an increase in the value of the other variable. This means that as one variable increases, the other variable also tends to increase.

Thus, as the pound increased, so did the number of apples, so this is a positive association

hat is the image of ( − 12 , 4 ) (−12,4) after a dilation by a scale factor of 1 4 4 1 ​ centered at the origin

Answers

The image of (-12, 4) after a dilation by a scale factor of 1/4 centered at the origin is (-3, 1).

What is image of points?

In geometry, the image of a point is the position of that point after a transformation. The transformation can be a translation, rotation, reflection, dilation or any combination of these.

When we apply a transformation to a point, the resulting image may be located at a different position in the plane, or it may be the same point if the transformation is an identity transformation (i.e., no change occurs).

For example, if we translate a point (x, y) by a distance of (a, b), then its image (x', y') can be found using the formula,

x' = x + a

y' = y + b

Similarly, if we rotate a point (x, y) by an angle of θ degrees around the origin, then its image (x', y') can be found using the formula:

x' = xcos(θ) - ysin(θ)

y' = xsin(θ) + ycos(θ)

Likewise, if we reflect a point (x, y) about the x-axis, then its image (x', y') can be found using the formula,

x' = x

y' = -y

And if we dilate a point (x, y) by a scale factor of k with respect to a center of dilation (h, k), then its image (x', y') can be found using the formula,

x' = h + k(x - h)

y' = k(y - k)

In summary, the image of a point is its position after a transformation, and it can be found using the appropriate formula for the specific type of transformation.

Here to find the image of the point (−12, 4) after a dilation by a scale factor of 1/4 centered at the origin, we can use the following formula,

(x', y') = (1/4)(x, y) where (x, y) is the original point, and (x', y') is its image after dilation.

Substituting the values of the original point,

(x', y') = (1/4)(-12, 4)

Simplifying,

(x', y') = (-3, 1)

Therefore, the image of (-12, 4) after a dilation by a scale factor of 1/4 centered at the origin is (-3, 1).

You roll a 6-sided die two times. What is the probability of rolling a number less than 4 and then rolling a number greater than 3?

Answers

Answer:

Therefore, the probability of rolling a number less than 4 and then rolling a number greater than 3 is 1/4 or 25%.

Step-by-step explanation:

The probability of rolling a number less than 4 on a 6-sided die is 3/6 or 1/2. The probability of rolling a nur than 3 is also 3/6 or 1/2.

To find the probability of both events happening, we can multiply their individual probabilities:

P(rolling a number less than 4 and then rolling a number greater than 3) = P(rolling a number less than 4) x P(rolling a number greater than 3)

= 1/2 x 1/2

= 1/4

Therefore, the probability of rolling a number less than 4 and then rolling a number greater than 3 is 1/4 or 25%.

The

probability of rolling a number less than 4 on a 6-sided die is 3/6 or 1/2. The probability of rolling a number greater than 3 on a 6-sided die is also 3/6 or 1/2.

To find the probability of both events happening, we multiply the probabilities:

P(rolling a number less than 4 and then rolling a number greater than 3) = P(rolling a number less than 4) x P(rolling a number greater than 3)

P(rolling a number less than 4 and then rolling a number greater than 3) = 1/2 x 1/2 = 1/4

Therefore, the probability of rolling a number less than 4 and then rolling a number greater than 3 is 1/4.

Two SUVs head toward each other from opposite ends of a freeway 639 miles long. If the speed of the first SUV is 39 miles per hour and the speed of the second SUV is 32 miles per hour, how long will it take before the SUVs pass each other?

Answers

Answer:

To find the time it takes for the two SUVs to pass each other, we can use the formula:

time = distance / relative speed

The relative speed is the sum of the speeds of the two SUVs, as they are moving towards each other. Let's calculate it:

Relative speed = speed of first SUV + speed of second SUV

Relative speed = 39 mph + 32 mph

Relative speed = 71 mph

Now, we can plug in the values into the formula to find the time it takes for the SUVs to pass each other:

time = 639 miles / 71 mph

Using division, we get:

time = 9 hours

So, it will take 9 hours for the two SUVs to pass each other.
