Answer:
x+63 = 90
x = 27
Step-by-step explanation:
The two angles are complementary, so they add to 90 degrees
x+63 = 90
Subtract 63 from each side
x+63-63 = 90-63
x = 27
Answer:
From -2<x<-1, the function F(X) is increasing. (B)
Really, it increases all from around -2.5<x<0.5
C is also the second answer, as it increases til around 2.5
It is decreasing from -4<x<-3. But increases right after. It then starts to slow down around x = 1 and go down again.
Which means (B) is your answer.
If you want to get fancy, its a polynomial and if you take the derivative for instantaneous rate, you will see f prime is increasing if you make an example function.
