Find the inverse of the function f(x)=8^x
ludmilkaskok [199]

Answer:

y = logx/log8

Step-by-step explanation:

To find the inverse of an equation, you switch the locations of x and y, then solve for y.

So in this case, f(x) = y, and your equation is:

y = 8^x

It would become

x = 8^y

There are multiple ways to solve this- one I usually use is logs, so you take the log of both sides.

log x = ylog8

(when you take the log of something the exponent becomes a coefficient)

Then, y = logx/log8

I hoped this helped!

Liam wants to save $6,265 to purchase a car. if $4,000 is deposited into an account at 7.5% interest, compounded monthly, how ma
timurjin [86]
To solve for time taken we use the compound formula:
A=P(1+r/100*n)^(n*t)
where:
A=future value
P=principle
r=rate
t=time
n=number of terms

6265=4000(1+7.5/(12*100))^(12t)
solving for t we get
1.56625=1.00625^12t
12t=72.0136
t=6.00 years

Solve the following equation : 7x/15-1=22
miskamm [114]
\frac{7x}{15-1} =22
-----------------
To solve this all it takes is two simple steps
Simplify \frac{7x}{15-1} =22
1/2x =22
------------------------
Multiply both sides by 2
2 · \frac{1}{2} = 2 · 22
x = 44
