A principal of $3500 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 13 years? Us

Anna71 [15]

The equation is for when you compound annually is
$A=P(1+r)^t$

A=future amount
P=initial amount or principal
r=interest rate in decimal form
t=time in years

so
A=A
P=3500
r=7.5%=0.075
t=13

$A=3500(1+0.075)^{13}$
$A=3500(1.075)^{13}$
use your calculator
A=8961.4457
round to nearest dollar
A=$8961

that's how much the investment will be worth after 13 years

What is the equation of the line passing through the points (4, -7.5) and (6, -3.5) in slope-intercept form?

Ratling [72]

Answer:

Your answer will be

y=2x-15.5

Step-by-step explanation:

Hi, there you must know the slope-intercept form which is

y=mx+b

m=slope

b=y-intercept

You can also use

the slope formula which is

$\frac{y_2-y_1}{x_2-x_1}$

in this case

it will look like this

$\frac{-7.5-(-3.5)}{6-4}$ = $\frac{-4}{2}$ =-2

So the slope is -2

Now we will find the y-intercept

-7.5=2(4)+b

-7.5=8+b Subtract 8 both sides

-15.5=b

Your y-intercept is -15.5

Hope this helps
