The maximum walking speed (in feet per second) of a large animal can be modeled by the equation S = sqrt(gL) where S = speed in

feet per second, g = a constant rate of 32 feet per second, and L = the length of one leg of the animal, in feet.
What domain makes sense for the function S(L) = sqrt(gL)

A. L is any real number
B. 0 < L <= 32
C. L > 0
D. L >= 32

What range makes sense for the function S(L) = sqrt(gL)?

A. 0 < S <= 32
B. S => 32
C. S > 0
D. S is any real number

Please help me!! And thank you :)

1. The domain of a sqrt(x) is x > 0. So, L > 0.
2. The range of a S(x) = sqrt(x) is S(x) > 0 for all valid x > 0.

Answer:

36.8 minutes or 36 minutes 48 seconds

Step-by-step explanation:

8 percent of 40 is 3.2

Elliott is standing at the top of a store escalator that leads to the ground floor below. the angle of depression from the top o
erma4kov [3.2K]

By using what we know about right triangles, we conclude that the height is 11ft.

<h3>How far is the top of the escalator from the ground floor? </h3>

We can think of this as a right triangle.

Where the length of the escalator is the hypotenuse

We know that the angle of depression is 42.51°, then the top angle of our right triangle is:

90° - 42.51° = 47.49°

Now, the height of the top of the escalator would be the adjacent cathetus to said angle, then we can use the relation:

cos(a) = (adjacent cathetus)/(hypotenuse)

Replacing what we know:

cos(47.49°)  = height/16ft

cos(47.49°) *16ft = height = 10.8ft

Rounding to the nearest foot, we get:

height = 11ft
