Answer:
4.33333333333
Step-by-step explanation:
Angle of elevation is 15 degrees and we're trying to solve for the hypotenuse of the right triangle given the adjacent is 7.11 m.
We could use primary trig ratios to solve - COS.
Let x represent the length of the ramp (hypotenuse)
Cos15= ADJACENT/HYPOTENUSE
Cos15= 7.11/x
x=7.11/cos15
x=7.36 m
<span>Therefore, the ramp is 7.36 m in length.

Answer:
D. 3x² - x - 6
Step-by-step explanation:
If f(x) = 3x² - 4 and g(x)= x+2, find .
We know that (f - g)(x) = f(x) - g(x)
Then
(f - g)(x) = (3x² - 4) - (x+2)
= 3x² - 4 - x - 2
= 3x² - x - 4 - 2
= 3x² - x - 6
The answer is: y = 3x + -5
