Answer:
(g - h)(-4x) = 4x - 2
Step-by-step explanation:
This problem is one dealing with "composite functions." We are given the definitions of functions g(x) and h(x) and are asked to find the difference between g and h, namely, what is left if we subtact h from g. After having done that, we replace x in this composite function with the input (-4x).
The difference (g - h)(x) is as follows: g(x) - h(x) = -x + 4x - [4x + 2].
If we simplify the algebra, we get g(x) - h(x) = -x + 4x - [4x + 2] = -x - 2.
Next, substitute -4x for x in this last result. We get (g - h)(-4x) = 4x - 2.
Please note: You might want to check out your g(x) = -x + 4x. Normally we would write this as +3x.
Answer:
59°
Explanation:
If you add the angles 99° from angle C in the top shape and add 22° on the bottom shape it will give you 121°. When you get this subtract it from 180°
180°-121°= 59°
So, it's 58°
You can check by adding 180°+121°+59° = 180°
Answer:
3rd option
Step-by-step explanation:
Using the identities
cot x = 
csc² x = 1 + cot² x
Given
tanθ = 
, then cotθ = 
csc²θ = 1 + ( )² = 1 + 
= 
cscθ = ± 
= ± 
Since θ is in 3rd quadrant, then cscθ < 0
cscθ = - × 
= -
