Answer:

( -5•2x8y)

Step-by-step explanation:

Changes made to your input should not affect the solution:

(1): "^-1" was replaced by "^(-1)".

Equation at the end of step 1

((5•(x3))•(y2))•(0-(2x5•y(-1)))

Equation at the end of step

(5x3 • y2) • -2x5y(-1)

Multiplying exponential expressions :

3.1 x3 multiplied by x5 = x(3 + 5) = x8

Multiplying exponential expressions :

3.2 y2 multiplied by y(-1) = y(2 + (-1)) = y1 = y

Answer:

20cm

Step-by-step explanation:

Let s = the length of the base

Let 4s = the length of the height

V = BH Since the base is a square, B = s2

V = s2 H

500 = s2(4s)

125 = s3

s = 5 cm

4s = 20 cm - the height

4. James and Terry open a savings account that has a 2.75% annual interest rate, compounded monthly. They

Zinaida [17]

$ 159,744.59 will be in the account after 20 years.

Answer: Option A

<u>Step-by-step explanation:</u>

Need to find out the amount present in the account after 20 years. The formula to find out the future value is,

$\text {Future value}=p \times\left(\frac{\left(1+\frac{r}{n}\right)^{n t}-1}{\frac{r}{n}}\right)$

Here

p : amount deposit monthly =$500

r : rate of interest = $\frac{2.75}{100}$ = 0.0275

n : 12(compound monthly)

t : time =20

By substituting all the given datas in the above equation, we get

$\text { Future value }=500 \times\left(\frac{\left(1+\frac{0.0275}{12}\right)^{240}-1}{\frac{0.0275}{12}}\right)$

$\text {Future value}=500 \times\left(\frac{(1+0.002291)^{240}-1}{0.002291}\right)=500 \times\left(\frac{(1.732)-1}{0.002291}\right)$

$\text { Future value }=500 \times\left(\frac{0.732}{0.002291}\right)=500 \times 319.511=\$ 159,744.99$
