x=5,3

Answers

8/x + 15/x^2 = -1
(8x+15)/x^2 = -1
8x + 15 = -1*x^2
8x + 15 = -x^2
x^2 + 8x + 15 = 0
(x+5)(x+3) = 0

Answer:

Step-by-step explanation:

n is the number of times the interest compounds per year. If the interest in this problem only compounds once per year ("annually"), then n = 1 and you'd be just as well off to use the formula:

$A=P(1+r)^t$

When n = 1, r/n is just r. But I'll show you using the formula they want you to use; it's the same anyways.

For us, P = 500, r = .015, n = 1. Filling that into the formula:

$A=500(1+(.015)/(1))^((1)(t))$ which simplifies down to

$A=500(1+.015)^t$ and

$A=500(1.015)^t$ (see what I meant about not having to use the formula with "n" in it if n 1?)

That formula is the answer to part a. For part b, we are to find how long it takes for the account to reach $800. $800 goes in for A:

$800=500(1.015)^t$

Begin by dividing both sides by 500 to get:

$1.6=(1.015)^t$

The only way to bring that t down from its current exponential position is to take the natural log of both sides. I will do that and at the same time apply the power rule for logs which says the exponent will come down out in front of the log:

$ln(1.6)=tln(1.015)$

Divide both sides by ln(1.015):

$(ln(1.6))/(ln(1.015))=t$

Do this on your calculator to find that

t = 31.5 years

A share of stock in the Bree Medical Supply Company is quoted at 35 1/4 . Suppose you hold 20 shares of that stock, which you bought at 31 1/2. If you sold your stock at 35 1/4, which of the following would be true?

Answers

If you will sell the 20 stocks you will gain $75 or $3.75 per stock. This is computed as follows:

35 1/4 - 31 1/2; 35.25 - 31.5 = 3.75
=3.75 x 20
=$75
