Answer:

The Answer is approximately 12.71 seconds.

Step-by-step explanation:

The form of the equation is:

f(x) = ab^x

Substitute:

f(x) = 8(1.22)^x

Solve for:

f(x) = 100

100 = 8(1.22)^x

100/8 = 1.22^x

12.5 = 1.22^x

1.22^x = 12.5

log(1.22^x) = log(12.5)

x * log(1.22) = log(12.5)

x * 0.0863 = 1.0969

x = 1.0969 / .0863 = 12.71 seconds, approximately

Solve the equation. 8x2 – 4 = 28
Flura [38]
Hello,

Your answer would be 2, -2.

8x^2 - 4 = 28

8x^2-4+4=28+4

8x^2 = 32

\frac{8x^2}{8}=  \frac{32}{8}  


x^2 = 4

x = +/4 

x = 2 or x = -2

2 , -2 would be the answer! :)
