Answer:
D. 3x + 12
Step-by-step explanation:
Distribute the 3 inside.
3 * x = 3x
3 * 4 = 12
3x + 12
we know that f(1)=2 so f^-1(2)=1
so B is correct!
You would divide 8 by 9, because the is inside the bracket division sign.
Hope this helps!
80 degrees because it decreases by a half each time so by the time it is E (the fourth letter) it has gotten to 20 so the answer is 160
Step-by-step explanation:
1/sin^2A -cos^2A/sin^2 A. ~tan = sin/cos
(1-cos^2)/sin^2A. ~ take lcm
sin^2A/sin^ A. ~ 1-cos^2A = sin^2A
