gavmur [86]

Answer:

  • C) (3, 4)
  • B) (-1, 9)

Step-by-step explanation:

<u>Use midpoint formula</u>

  • x = (x₁ + x₂)/2
  • y = (y₁ + y₂)/2

#3

Endpoints (0, 0) and (6, 8)

<u>Midpoint has coordinates:</u>

  • x = 6/2 = 3, y = 8/2 = 4
  • Point is (3, 4)

Correct choice is C

#4

Endpoints (-5, 3) and (3, 15)

<u>Midpoint has coordinates:</u>

  • x = (-5 + 3)/2 = -1, y = (3 + 15)/2 = 9
  • Point is (-1, 9)

Correct choice is B

You have $500,000 saved for retirement. Your account earns 8% interest. How much will you be able to pullout each month, if you
borishaifa [10]

The rule of the payout annuity is

P=\frac{d(1-(1+\frac{r}{n})^{-nt})}{\frac{r}{n}}

P is the initial amount

d is regular withdrawals

r is the annual rate in decimal

n is the number of periods in a year

t is the time

Since you have $500 000 saved, then

P = 500000

Since the interest is 8%, then

r = 8/100 = 0.08

Since the time is 15 years, then

t = 15

Since you want the monthly amount, then

n = 12

Substitute them in the rule to find d

\begin{gathered} 500000=\frac{d(1-(1+\frac{0.08}{12})^{-12(15)})}{\frac{0.08}{12}} \\ 500000(\frac{0.08}{12})=d(1-(\frac{151}{150})^{-180}) \\ \frac{10000}{3}=d(1-(\frac{151}{150})^{-180}) \\ \frac{\frac{10000}{3}}{(1-(\frac{151}{150})^{-180})}=d \\ 4778.260422=d \end{gathered}

Then you will be able to pull $4778.260422 each month
