Answer:
D
Step-by-step explanation:
Find (f + g)(x) then evaluate (f + g)(9)
(f + g)(x) = f(x) + g(x)
= 4x - 1 + x² - 2 = x² + 4x - 3
Now substitute x = 9 into the expression
(f + g)(9) = 9² + 4(9) - 3 = 81 + 36 - 3 = 114 → D
The answer would be 4380 more hours.

Answer:
The volume of the dirt is
Step-by-step explanation:
We have, a truckload of fill dirt is dumped in front of a newly-built home. The pile of dirt is cone-shaped.
Height of pile of dirt is 7 feet and its diameter is 15 feet.
It is required to find the volume of the dirt.
The formula of the volume of cone is given by :
r is radius of cone shaped, r = 7.5 feet
So, the volume of the dirt is .
Rather than try to select the correct answer without doing work, I'd rather do the work first and the matching later.
Given y = 4 - x, or y = 4 - 1x,
1) the y-intercept is (0,4).
2) this being a linear function, it has neither maximum nor minimum.
3) the x-intercept is found by letting y = 0 and solving for x: 0 = 4 - x; x - 4. The x-intercept is (4,0).
Which of the given statements is true?
