From the identity:


the inverse of f is g such that f(g(x))=x,
we must find g(x), such that
![\frac{1}{cos[g(x)]}=x](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7Bcos%5Bg%28x%29%5D%7D%3Dx%20)
thus,
![cos[g(x)]= \frac{1}{x}](https://tex.z-dn.net/?f=cos%5Bg%28x%29%5D%3D%20%5Cfrac%7B1%7D%7Bx%7D%20)

Answer: b. g(x)=cos^-1(1/x)
Answer:
It is 7.5%.
Step-by-step explanation:
15 x
200 100
1500/200 = 7.5

Answer:
The solution set for the inequality is the interval (-4, 5)
Step-by-step explanation:
-8 < 8 + 4x < 28
Subtracting 8:
-8 -8 < 8 + 4x - 8 < 28 - 8
-16 < 4x < 20
Dividing by 4:
-16/4 < 4x/4 < 20/4
-4 < x < 5
x ∈ (-4, 5)
Answer: 60% increase followed by a 40% decrease belongs in less than original. A 50% increase followed by a 33 1/3 decrease also belong in less than original. A $20 decrease followed by a $20 increase belongs in same as original. A 75% decrease followed by a 50% increase belongs in less than original. A 100% increase followed by a 33 1/3 decrease belongs in less than original.
Step-by-step explanation:
Hope this helps :)
