Aman is 6 feet 3 inches tall. the top of his shadow touches a fire hydrant that is 13 feet 6 inches away. what is the angle of elevation from the base of the fire hydrant to the top of the man's head?

Step-by-step explanation:

Given: A man is 6 feet 3 inches tall.

Since 1 feet = 12 inches

Therefore, 6 feet 3 inches=

The top of his shadow touches a fire hydrant that is 13 feet 6 inches away.

Here,  13 feet 6 inches=

Since the man is standing vertical to the ground, therefore he make right angle with the ground.

let x be the angle of elevation from the base of the fire hydrant to the top of the man's head.

We know that in a right triangle,

question:

could we have options?

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
