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

Step-by-step explanation:

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

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

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

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

9[[w]^[5]]+24[[w]^[4]]+16[[w]^[3]] I need to simplify this.

kupik [55]

$9w^5 + 24w^4 + 16w^3$

Factor out w³.

$w^3(9w^2+24w+16)$

Find two numbers that multiply to equal 144 (9*16) and add to equal 24.
This would be 12 and 12.

$w^3(9w^2+12w+12w$

Factor.

$w^3(3w(3w+4)+4(3w+4))$ +16)[/tex]

Simplify.

$w^3(3w+4)(3w+4) = w^3(3w+4)^2$
