Explain a little bit deeper and i would love to help
f(x) = x + 4
g(x) = x² - x
a) f(5)
f(5) = 5 + 4 = 9
b) g(-1)
g(-1) = (-1)² -(-1) = 1 + 1 = 2
c) f(x) = 10
10 = x + 4
x = 6
d) g(x) = 6
6 = x² - x
0 = x² - x - 6
0 = (x - 3)(x + 2)
x = 3, -2
Answer:
26
Step-by-step explanation:
4 + 2 + 3 + 4 + 7 + 6

The first thing we need to do is use tan to find x. If the original angle of depression is 7 degrees, then the angle from the cliff to the bow of the boat is 90-7=83 degrees. Thus,<span>tan83 = <span>d / 150</span></span>or we can express it like this:<span>d =150 tan 83 ≈ 855.2</span><span>where d is the total distance from the boat to the cliff when the angle of depression is 7 degrees. Hope this helps a lot</span>
