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
(2x^3+4x^2-4x+6) / (x+3) = 2x^2-2x+2 => B
1/25
= 5^4/5^6
= 1/5^6-4
= 1/5^2
= 1/25
hope it helps!
