How much would $100 invested at 8% intrest compounded annually be worth after 15 years? round your answer to the nearest cent. d

frosja888 [35]

Our P = 100, r = .08, n = 1 (annually means once a year), and t = 15. Filling in accordingly, we have $A(t)=100(1+ \frac{.08}{1})^{(1)(15)}$ . Simplifying a bit gives us $A(t)=100(1+.08)^{15}$ and $A(t)=100(1.08)^{15}$ . Raising that number inside the parenthesis to the 15th power gives us $A(t)=100(3.172169114)$ . Multiplying to finish means that A(t) = $317.22

For which function does f decrease by 15% every time x increases by 1

LenaWriter [7]

Answer:

$f(x) = 0.85^{x}$

Step-by-step explanation:

The exponential function that decrease by 15% every time x increases by 1 is given by:

$f(x) = {(1 - 0.15)}^{x}$

We simplify the parenthesis to get:

$f(x) = 0.85^{x}$

Therefore the decrease by 15% every time x increases by 1 is

$f(x) = {0.85}^{x}$

The second choice is correct.

Solve by factoring m^2+8m+7=0

Alenkinab [10]

We can use completing the square.We add 16 and subtract 7 to both sides. Now we get m^2+8m+16=9. The left sides becomes (m+4)^2=9. Taking the square root of both sides and subtracting 4 we get -1 and -7.
