An engineer, in an attempt to make a quick measurement, walks 100 ft from the base of an overpass and determines that the angle of elevation to the overpass is 15°. Draw a diagram and solve for the
distance the overpass is above the ground.

The distance of the overpass above the ground is approximately 26.795 ft

Step-by-step explanation:

The parameters given are;

The distance from the overpass the engineer stands before determining the angle of elevation of the overpass from his standing point = 100 ft

The angle of elevation of the overpass as determined by the engineer from 100 ft = 15°

By trigonometric ratios, we have;

The opposite side to the 15° angle of elevation in the above case is the distance of the overpass above the ground

The opposite side to the 15° is the distance of the engineer from the base of the overpass

Therefore;

Tan(15°)  the height of the overpass=

length

The distance of the overpass above the ground = 100 × tan (15°) ≈ 26.795 ft.

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.

if you need just tell me and i will come to the rescue.
