Answer:
A
Step-by-step explanation:
Automatically if you use the intercept (where it cuts the line) which would be 3.
Answer:
![f^{-1}(x) = log_{12}(y)](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20log_%7B12%7D%28y%29)
Step-by-step explanation:
We have the following function
y = 12^x, and we need to find the inverse function.
To find the inverse function we should solve the equation for "x". To do so, first, we need to:
1. Take the logarithm in both sides of the equation:
lg_12 (y) = log _12 (12^x)
(Please read lg_12 as: "Logarithm with base 12")
From property of logarithm, we know that lg (a^b) = b*log(a)
Then:
lg_12 (y) = x*log _12 (12)
We also know that log _12 (12) = 1
Then:
x = log_12(y).
Then, the inverse of: y= 12^x is:
![f^{-1}(x) = log_{12}(y)](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20log_%7B12%7D%28y%29)
Answer:
A)3
Step-by-step explanation:
Yo sup??
you can solve this quesion by having the knowledge of trigonometric ratios
let angle B be x, then
tanx=7/3
x=66.8
Hope this helps
