Answer:

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.

F(x) = 4x − 12 <br><br> f−1(x) =___? x +____?

natali 33 [55]

Answer:

$f^{-1}(x)=\frac{1}{4}x+3$

Step-by-step explanation:

We have been given the function $f(x)=4x-12$

Below are steps for finding the inverse of the function.

Step 1:

Replace f(x) with y

$y=4x-12$

Step 2:

Interchange x and y

$x=4y-12$

Step 3:

Solve for y

$x+12=4y\\\\y=\frac{1}{4}x+3$

Step 4:

Replace y with $f^{-1}(x)$

$f^{-1}(x)=\frac{1}{4}x+3$

The angled of a triangle are in the ratio of 2:3:4 find angles in degrees

jeyben [28]

40°, 60° and 80°

sum the parts of the ratio 2 + 3 + 4 = 9

The sum of the angles in a triangle = 180°

Divide 180 by 9 to find one part of the ratio

$\frac{180}{9}$ = 20° ← 1 part of the ratio

2 parts = 2 × 20 = 40°

3 parts = 3 × 20 = 60°

4 parts = 4 × 20 = 80°

The angles in the triangle are 40°, 60° and 80°
