Answer:
4:1
Step-by-step explanation:
8/2 = 4:1 cause 2 can go into 8, 4 times.
A rubber ball is dropped from a height of 26 feet, and on each bounce it rebounds up 62% of its previous height. Step 2 of 2: Assuming the ball bounces indefinitely, find the total vertical distance traveled. Round your answer to two decimal places.
The total vertical distance traveled by the rubber ball, assuming it bounces indefinitely, is approximately 85.71 feet.
To find the total vertical distance traveled, we need to sum up the heights achieved by the ball during each bounce. The ball initially drops from a height of 26 feet, so we start with this value. On each bounce, the ball rebounds up 62% of its previous height. This means that after the first bounce, the ball reaches a height of 26 feet * 0.62 = 16.12 feet.
For subsequent bounces, we continue to multiply the previous height by 0.62 to find the new height. Therefore, after the second bounce, the height becomes 16.12 feet * 0.62 = 9.99 feet.
We can see that the heights achieved during each bounce form a geometric sequence with a common ratio of 0.62. The sum of an infinite geometric sequence can be calculated using the formula,
Sum = a / (1 - r), first term is a and 'r' is the common ratio is r.
In this case, 'a' is the initial height of 26 feet and 'r' is 0.62. Plugging these values into the formula, we get,
Sum = 26 / (1 - 0.62) = 26 / 0.38 ≈ 68.42 feet.
Therefore, adding all the distances,
Distance = 68.42 + 9.99 + 16.12
Distance = 85.71 feet, total vertical distance traveled by the rubber ball, rounded to two decimal places, is approximately 85.71 feet.

Two particles, Alpha and Beta, race from the y-axis to the vertical line x = 6*pi. For t >= 0, Alpha's position is given by the parametric equations xalpha = 3t - 4sin(t) and yalpha = 3 - 3cos(t) while Beta's position is given by xbeta = 3t - 4sin(t) and ybeta = 3 - 4sin(t). Which sentence best describes the race and its outcome?
(A) Beta starts out in the wrong direction and loses.
(B) Alpha takes a shorter path and wins.
(C) Alpha moves slower and loses.
(D) Beta moves faster but loses.
(E) Alpha and Beta tie
The outcome of the race between Alpha and Beta, as described by their parametric equations, is that Beta moves faster but loses. Although Beta has a higher speed, Alpha consistently maintains a higher vertical position, leading to Alpha winning the race.
To determine the outcome of the race between Alpha and Beta, let's compare their positions using the given parametric equations:
Alpha's position:
[tex]x_{alpha} = 3t - 4sin(t)\\y_{alpha}= 3 - 3cos(t)[/tex]
Beta's position:
[tex]x_{beta} = 3t - 4sin(t)\\y_{beta} = 3 - 4sin(t)[/tex]
From the equations, we can see that the x-coordinate of both Alpha and Beta is the same, given by 3t - 4sin(t). Therefore, their horizontal positions are identical throughout the race.
To determine the vertical positions, we compare their y-coordinates. Alpha's y-coordinate is given by 3 - 3cos(t), while Beta's y-coordinate is given by 3 - 4sin(t).
Since cos(t) ranges from -1 to 1, and sin(t) ranges from -1 to 1, we can observe the following:
For Alpha, the y-coordinate (3 - 3cos(t)) ranges from 0 to 6, inclusive.
For Beta, the y-coordinate (3 - 4sin(t)) ranges from 2 to 4, inclusive.
Based on the range of their y-coordinates, we can conclude that Beta remains at a higher position throughout the race. Therefore, the correct answer is:
(D) Beta moves faster but loses.
Despite Beta moving faster, it loses the race because Alpha consistently maintains a higher vertical position.
Therefore, the outcome of the race between Alpha and Beta, as described by their parametric equations, is that Beta moves faster but loses. Although Beta has a higher speed, Alpha consistently maintains a higher vertical position, leading to Alpha winning the race.

5. Find the following limits. (a) lim40 12 (b) limz+1+1 +22-22+2 i 2-iz-1-1
The limits are,
(a) lim(x→0) 4x/(x² + 1) = 0
(b) lim(z→-1) (1 + √(2 - 2z + z²))/(2 - iz - 1) = ((1 + √(5))(3 - i))/10
(a) To find the limit of lim(x→0) 4x/(x² + 1), we can directly substitute 0 for x in the expression:
lim(x→0) 4x/(x² + 1) = (4 × 0)/(0² + 1) = 0/1 = 0
Therefore, the limit is 0.
(b) To find the limit of lim(z→-1) (1 + √(2 - 2z + z²))/(2 - iz - 1), we can again substitute -1 for z in the expression:
lim(z→-1) (1 + √(2 - 2z + z²))/(2 - iz - 1) = (1 + sqrt(2 - 2(-1) + (-1)^2))/(2 - i(-1) - 1)
= (1 + √(2 + 2 + 1))/(2 + i + 1)
= (1 + √(5))/(3 + i)
To simplify this expression further, we need to rationalize the denominator. We can multiply the numerator and denominator by the conjugate of the denominator, which is (3 - i):
lim(z→-1) (1 + √(5))/(3 + i) × (3 - i)/(3 - i)
= ((1 + √(5))(3 - i))/(9 - i²)
= ((1 + √(5))(3 - i))/(9 + 1)
= ((1 + √(5))(3 - i))/10
Therefore, the limit is ((1 + √(5))(3 - i))/10.

What is the biggest difference between exponential functions and other functions you have learned about up to this point?
Answer:
No no don't click the link
Answer:
The biggest difference between exponential and linear functions is that linear functions change at a constant rate, while exponential functions change at a rate proportional to it's value, or exponent.
Basically, that's also what separates exponential functions from all others. It's the only function that changes at a rate proportional to its exponent.

Mrs. Smith washed 2 5 of her laundry. Her son washed 1 3 of it. Who washed most of the laundry? How much of the laundry still needs to be washed?
Answer:
a) The person who washed the most of the laundry is Mrs Smith
b) 4/15 of the laundry is left to wash
Step-by-step explanation:
Mrs. Smith washed 2/5 of her laundry. Her son washed 1/3 of it.
a) Who washed most of the laundry?
We convert the fraction of laundry each person washed to decimal
Mrs Smith = 2/5 = 0.4
Her son = 1/3 = 0.333
Therefore, the person who washed the most of the laundry is Mrs Smith
b) How much of the laundry still needs to be washed?
Let us total laundry = 1
=1 - ( 2/5 + 1/3)
Lowest Common Denominator is 15
=1- (3 × 2 + 5 × 1/15)
= 1 - (6 +5/15)
=1 - 11/15

The diameter of a circle is 63 centimetres find its circumference use pie = 3.14
Answer:
197.9
Step-by-step explanation:
The formula for circumference is 2(pi)r and r is the radius
The diameter is two times the size of the radius, so by dividing the diameter by two, you can get the radius
So, r=63/2
r= 31.5
That means that 2(pi)(31.5) is the circumference
2(pi)(31.5) = 197.9 (rounded to the nearest tenth)
Solve the following problem using Simplex Method: MAX Z=6X1 + 10X2 + 5 X3 ST X1 + 2X2 + 4X3 <=8 6X1 + 4X2 <=24 6X1 + 5X3 <=30 X1,X2,X3 >=0
The maximum value of the objective function Z is 120. The optimal values for the decision variables are X1 = 8, X2 = 0, and X3 = 0. The constraints are satisfied, and the optimal solution has been reached using the Simplex Method.
To compute the problem using the Simplex Method, let's convert it into standard form.
Maximize:
Z = 6X1 + 10X2 + 5X3
Subject to the constraints:
X1 + 2X2 + 4X3 <= 8
6X1 + 4X2 <= 24
6X1 + 5X3 <= 30
X1, X2, X3 >= 0
Introducing slack variables S1, S2, and S3 for each constraint, the constraints can be rewritten as equalities:
X1 + 2X2 + 4X3 + S1 = 8
6X1 + 4X2 + S2 = 24
6X1 + 5X3 + S3 = 30
Now, we have the following equations:
Objective function:
Z = 6X1 + 10X2 + 5X3 + 0S1 + 0S2 + 0S3
Constraints:
X1 + 2X2 + 4X3 + S1 = 8
6X1 + 4X2 + S2 = 24
6X1 + 5X3 + S3 = 30
X1, X2, X3, S1, S2, S3 >= 0
Next, we will create the initial simplex tableau:
| X1 | X2 | X3 | S1 | S2 | S3 | RHS |
---------------------------------------
Z | 6 | 10 | 5 | 0 | 0 | 0 | 0 |
---------------------------------------
S1 | 1 | 2 | 4 | 1 | 0 | 0 | 8 |
---------------------------------------
S2 | 6 | 4 | 0 | 0 | 1 | 0 | 24 |
---------------------------------------
S3 | 6 | 0 | 5 | 0 | 0 | 1 | 30 |
---------------------------------------
By performing the simplex pivot operations and iterating through the simplex method steps, we find the following tableau:
| X1 | X2 | X3 | S1 | S2 | S3 | RHS |
---------------------------------------
Z | 0 | 0 | 5 | -6 | 0 | -60| 120 |
---------------------------------------
X1 | 1 | 2 | 4 | 1 | 0 | 0 | 8 |
---------------------------------------
S2 | 0 | -8 | -24| -6 | 1 | 0 | 0 |
---------------------------------------
S3 | 0 | 0 | -1 | -6 | 0 | 1 | 0 |
---------------------------------------
The optimal solution is Z = 120, X1 = 8, X2 = 0, X3 = 0, S1 = 0, S2 = 0, S3 = 0.
Therefore, the maximum value of Z is 120, and the values of X1, X2, and X3 that maximize Z are 8, 0, and 0, respectively.

Verify that f_xy = f_yx, for the function f(x,y) = 3x^7 + 4y^7 + 12.
For the function f(x,y) = 3x^7 + 4y^7 + 12, f_xy = f_yx since fx = ______ and fy = ____
Therefore, fxy= _______ and fyx = _______
Given the function: f(x,y) = 3x^7 + 4y^7 + 12To verify that f_xy = f_yx, we need to find the partial derivatives of the given function with respect to x and y. We can find them as follows: ∂f/∂x = 21x^6 ∂f/∂y = 28y^6
Now, to verify that f_xy = f_yx, we need to find f_xy and f_yx. We can find them as follows: f_xy = ∂^2f/∂y∂x = ∂/∂y(∂f/∂x) = ∂/∂y(21x^6) = 0 (since we have no y terms in the derivative of ∂f/∂x) f_yx = ∂^2f/∂x∂y = ∂/∂x(∂f/∂y) = ∂/∂x(28y^6) = 0 (since we have no x terms in the derivative of ∂f/∂y)Since f_xy = f_yx = 0, we can say that f_xy = f_yx.
Therefore, the value of fx is 21x^6 and the value of fy is 28y^6. Hence, the value of fxy is 0 and fyx is also 0.

A rectangular park, 90 meters by 60 meters, is to be built on a city block having an area of 9000 m^2. A uniform strip borders all four sides of the park for parking. How wide is the strip? Use quadratic formula and show your work.
Answer:
x = 10.52 m
Step-by-step explanation:
Given that,
Length of a park = 90 m
Width of a park = 60 m
Area, A = 9000 m²
A uniform strip borders all four sides of the park for parking. We need to find the width of the strip. Let it is x. Now the area becomes,
(90+2x)(60+2x) = 9000
[tex]4x^2 +120x +180x =5400 = 9000\\\\x=10.52\ m[/tex]
So, the width of the strip is equal to 10.52 m.
Determine the area and circumference of a circle with diameter 20 inches.
The area of the circle with a diameter of 20 inches is 100π square inches, and the circumference of the circle is 20π inches.
To determine the area and circumference of a circle with a diameter of 20 inches, you need to use the formulas for these measures.
A circle is a set of points that are equidistant from the center point, and the diameter of a circle is the longest line that can be drawn from one point on the circle to another while passing through the center point. The formulas for the area and circumference of a circle are as follows:
A = πr²C = πd
where A is the area of the circle, C is the circumference of the circle, r is the radius of the circle, d is the diameter of the circle, and π (pi) is a mathematical constant that approximates to 3.14.
To find the area of a circle with a diameter of 20 inches, you need to find the radius of the circle first. The radius is half of the diameter, so r = d/2 = 20/2 = 10 inches. Therefore, the area of the circle is:A = πr² = π(10)² = 100π square inches (rounded to two decimal places).
To find the circumference of a circle with a diameter of 20 inches, you can either use the formula C = πd or you can use the formula C = 2πr. Since you already know the diameter, let's use the first formula. C = πd = π(20) = 20π inches (rounded to two decimal places).
