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!
The answer is .037
I did this by putting it in the calculator:)
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
Answer: 6 years
Selling price=620(1-0.30)(1-0.15)(1-0.05)
selling price = 620(.7)(.85)(.95) = 350.46
-----------------
To solve this all it takes is two simple steps
Simplify
1/2x =22
------------------------
Multiply both sides by 2
2 ·
= 2 · 22
x = 44
