F(x)·g(x) = (3x +4)·(5 -x) = -3x^2 +11x +20

(f·g)(x) = -3x^2 +11x +20

Why do we multiply by sin -1 to cancel it out rather than divide by sin?
Leya [2.2K]

Answer:

The sin-1 is cancelling out the angle it has ordered.

Sin 45 = 1/ √ 2

This is why we can also check Cos 1/ √ 2 and Tan 1

Please answer correctly !!!!!!!!!! Will mark brainliest !!!!!!!!!!!!
Leto [7]

Answer:

see explanation

Step-by-step explanation:

(1)

Given

g(r) = (r + 14)² - 49

To obtain the zeros, let g(r) = 0 , that is

(r + 14)² - 49 = 0 ( add 49 to both sides )

(r + 14)² = 49 ( take the square root of both sides )

r + 14 = ± \sqrt{49} = ± 7 ( subtract 14 from both sides )

r = - 14 ± 7, then

r = - 14 - 7 = - 21 ← smaller r

r = - 14 + 7 = - 7 ← larger r

(2)

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

g(r) = (r + 14)² - 49 ← is in vertex form

with vertex = (- 14, - 49 )
