Answer:
9.80 m
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationship between sides of a right triangle and its angles.
__
<h3>setup</h3>The geometry of this problem can be modeled by a right triangle, so these relations apply. We are given an angle and adjacent side, and asked for the opposite side, so the relation of interest is ...
Tan = Opposite/Adjacent
Using the given values, we have ...
tan(24°) = AC/AB = (tree height)/(distance from tree)
tan(24°) = AC/(22 m)
<h3>solution</h3>Multiplying by 22 m gives ...
tree height = AC = (22 m)·tan(24°) ≈ 9.79503 m
The height of the tree is about 9.80 meters.
Answer:
6
Step-by-step explanation:
Your intervals are x=-2, and x=0. In this case, x=-2 will be a, and x=0 will be b.
To find the average rate of change, you have to first find f(-2) and f(0)
Then, f(0)
Now you know f(-2) is -11, and f(0) is 1.
Next, you plug these into the average rate of change formula, which is
Flug in -11 and 1 on the numerator, and -2 and 0 on the denominator.
