Elaine plans on saving $2,000 a year and expects to earn an annual rate of 8.8 percent. How much will she have in her account at

yKpoI14uk [10]

Answer:

$831,532.24

Step-by-step explanation:

The amount that will be in her account at ordinary annuity is derived using the formula:

$A(n) = \dfrac{P((1 + r)^{n}-1)}{r}$

Where:

Yearly Deposit,P=$2000

Annual rate,r=8.8%=0.088

Number of Years,n=43 years

$A(43) = \dfrac{2000((1 + 0.088)^{43}-1)}{0.088}\\\dfrac{2000[(1 .088)^{43}-1]}{0.088}\\A(43)=\$831,532.24$

At the end of 43 years, she would have <u>$831,532.24</u> in her account.

What is the area of the triangle? 5 4 3 units?

tankabanditka [31]

Answer:

6 units squared

Step-by-step explanation:

Formula:

area = 0.25 * √( (a + b + c) * (-a + b + c) * (a - b + c) * (a + b - c) )

Assign variables:

A = 5, B = 4, C = 3.

Distribute:

area = 0.25 * √( (5 + 4 + 3) * (-5 + 4 + 3) * (5 - 4 + 3) * (5 + 4 - 3) )

Combine like terms

area = 0.25 * √( (12) * (2) * (4) * (6) )

Multiply:

area = 0.25 * √(576)

Square root:

area = 0.25 * 24

Multiply:

area = 6 units squared
