, find f^{-1}(x)f −1 (x)

Stolb23 [73]

Answer:

Multiply the numerator by the reciprocal of the denominator. Multiply x x by 1 1 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=1x f - 1 ( x ) = 1 x is the inverse of f(x)=1x f ( x ) = 1 x .

What is the solution to this equation? x/-4=8 A. x = -32 B. x = 2 C. x = 32 D. x = -2

Hey! What you can do is plug them in or solve for x.
This is how you solve for x:
since its x is divided by -4 and you want to get x alone you should multiply -4 to the other side and so it would be x = -4*8.
That is -32.
The answer is A!
Hope this helps!

What is the measure (in radians) of central angle 0 in the circle below? Enter an exact expression.

Makovka662 [10]

Answer:

$\frac{\pi^{c} }{3}$

Step-by-step explanation:

Measure of the length of an arc of a circle is given as:

$l = \frac{ \theta}{2\pi} \times 2\pi r \\ \\ \pi = \frac{ \theta}{2\pi} \times 2\pi \times 3 \\ \\ 3 \theta = \pi^{c} \\ \\ \theta = \frac{\pi^{c} }{3} \\$
