Step-by-step explanation:

Use FOIL method.First multiply (5x + 1) and (3x - 4). Then multiply (15x² - 17x - 4) by (x +2)

Volume of the rectangular prism = length *width * height

              = (5x + 1) (3x -4)(x +2)

              = [ 5x*3x + 5x*(-4)  + 1*3x + 1*(-4) ] (x + 2)

             = [15x² - 20x + 3x - 4] (x +2)    {Combine like terms}

             = [15x² - 17x - 4] (x + 2)

             =[15x² -17x - 4]*(x) + [15x² - 17x  -4]*2

            = [15x²*x - 17x*x - 4*x ]+ 15x²*2 - 17x *2  - 4*2

            = 15x³ - 17x² - 4x  + 30x² - 34x - 8

           = 15x³ - 17x² + 30x²  - 4x - 34x - 8    {Combine like terms}

           = 15x³ + 13x²  - 38x - 8

Step-by-step explanation:

Exponential equation of decay:

The exponential equation for the decay of an amount after t years is given by:

[tex]A(t) = A(0)(1-r)^t[/tex]

In which A(0) is the initial amount and r is the decay rate, as a decimal.

If you buy a motorcycle for $12,500 in 2015 and it depreciates (shrinks) in value by 15.5% every year

This means that [tex]A(0) = 12500, r = 0.155[/tex]

So

[tex]A(t) = A(0)(1-r)^t[/tex]

[tex]A(t) = 12500(1-0.155)^t[/tex]

[tex]A(t) = 12500(0.845)^t[/tex]

How much will it be worth in 2020?

2020 is 2020 - 2015 = 5 years after 2015, so this is A(5). So

[tex]A(5) = 12500(0.845)^5 = 5385.10[/tex]

The correct answer is given by option D.

Answer:

3/100 × 30000 is the answer to your question.

Answer:

$8,511.1147

Step-by-step explanation:

Compound interest formula is expressed as;

A = P(1+r)^n

P is the amount invested = $6000

r is the rate = 6% = 0.06

t is the time = 6yrs

A is the compound amount

A = 6000(1+0.06)^6

A = 6000(1.06)^6

A  = 6000(1.4185)

A = 8,511.1147

Hence the compound amount to 4dp is $8,511.1147

Answer:

n = 6

Step-by-step explanation:

Given the expression

[tex](\frac{19^8}{7^n})^4 = (\frac{19^4}{7^3})^8 \\\frac{19^{32}}{7^{4n}} = \frac{19^{32}}{7^{24}}\\\frac{1}{7^{4n}} = \frac{1}{7^{24}} \\Reciprocate \ both \ sides\\7^{4n} = 7^{24}\\4n = 24\\n = \frac{24}{4}\\n = 6[/tex]

Hence the value of n is 6

Use the formula A = p(1 + r/n)^(nt).

Here is the set up:

A = 6500[1 + (0.08/4)]^(4•7)

Solve for A.

Answer:

y = 3x + 41

Step-by-step explanation:

First, lets set up the slope-intercept form equation, that is...

y = mx + b

m = slope

b = y-intercept

because the y-intercept is a positive value, it cannot be y=-3x-41 or y= 3x-41

now, we know that b = 41, but what is the slope?

Well, here are tips for doing slope

if the line is gradually increasing upwards, then it is a positive slope

if the line is gradually decreasing downwards, then it is a negative slope

because the line in the picture is positive, this proves y=-3x+41 wrong, therefore making y = 3x + 41 the only correct answer

Therefore, your correct answer is y = 3x + 41

Answer:

  216 feet

Step-by-step explanation:

The area is given by the formula ...

  A = LW

Solving for width, we have ...

  W = A/L = 2835 ft²/(45 ft) = 63 ft

__

The perimeter is given by the formula ...

  P = 2(L +W)

  P = 2(45 ft +63 ft) = 2(108 ft)

  P = 216 ft

216 feet of fencing are needed to enclose the area.

Answer:

D

Step-by-step explanation:

first multiply both sides by 12

collect like terms

x/12×12+3×12<=7×12

x+36<=84

x<=84-36

x<=48

Answer:

just substitute the value of x as 1

f(x)=3(12)x+1

f(1)=3(12)(1)+1

f(1)=3(12)(1)+1

f(1)=36+1

f(1)=37

Answer:

Step-by-step explanation:

We can first solve for the face diagonal. That is [tex]\sqrt{(10^2+5^2)}[/tex]. Notice this will form a right triangle with the vertical side. We get that the face diagonal = [tex]\sqrt{125}[/tex]. Now, we can use Pythagorean theorem again to get the straw length:

[tex]s^2 = 9^2+\sqrt{125}^2[/tex] where s = the straw length.

We can solve that s = [tex]\sqrt{206}[/tex]

Answer:

A)  159.135 = X

B) 2,531.25 = X

C)  6,187.5 = X

D) 831,947.46 = X

Step-by-step explanation:

The following investments are required to be calculated:

A) $ 150 at 3% interest for 2 years

B) $ 750.00 at 1/2% interest for 3 years

C) $ 2,250.00 at 1 3/4% interest for 1 year

D) $ 2,550.00 at 3 1/4 interest for 4 years

Therefore, the following calculations must be performed:

A)

150 x (1 + 0.03) ^ 2 = X

150 x 1.03 ^ 2 = X

159.135 = X

B)

750 x (1 + 0.5) ^ 3 = X

750 x 1.5 ^ 3 = X

2,531.25 = X

C)

2,250 x (1 + 1.75) = X

2,250 x 2.75 = X

6,187.5 = X

D)

2,550 x (1 + 3.25) ^ 4 = X

2,550 x 4.25 ^ 4 = X

831,947.46 = X

The two numbers are 3 and 8.

Square numbers are numbers that can be multiplied by themselves.

Given that, The sum of the squares of two positive numbers is 73 and the difference of the squares of the numbers is 55.

Let the numbers be x and y, then,

x²+y² = 73

x²-y² = 55

On solving, we get,

x² = 9

x = 3

Putting x = 3 in first equation, we get

3²+y² = 73

y² = 64

y = 8

Hence, the required numbers are 3 and 8.

Answer:

The monthly loan payment is of $458.88.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Amount owed after 5 years:

Loan of 24000 means that [tex]P = 24000[/tex]

5 years means that [tex]t = 5[/tex]

Interest rate of 2.75% means that [tex]r = 0.0275[/tex]

Compounded monthly means that [tex]n = 12[/tex]

The amount is A(5). So

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]A(5) = 24000(1 + \frac{0.0275}{12})^{12*5}[/tex]

[tex]A(5) = 27533[/tex]

What is your monthly loan payment?

$27,533 in 5 years = 5*12 = 60 months. So

27533/60 = 458.88

The monthly loan payment is of $458.88.
