A surveyor stands 75 feet from a building. He measures the angle of elevation to the top of the building at 67.5°. How tall is t

Serggg [28]

Answer:

1694 ft

Step-by-step explanation:

The adjacent side of this right triangle is 75 feet in length, and the two given angles are 90 degrees and 67.5 degrees. Since the adjacent side is given and the opposite side is what we are looking for we can use

tan(x) = opposite/adjacent insert the given information into the equation

tan(67.5) = opposite / 75ft multiply both sides of the equation by 75

tan(67.5)*75 = opposite leaving us with the target variable

once you plug that equation into a calculator you get 1694 as your nearest whole answer.

Errol's bike ride from home to school can be modeled by the equation d(t) = -4t+2, where d(t) is

8_murik_8 [283]

Answer:

Option (2).It has a vertical translation by 2 units in the positive direction.

Step-by-step explanation:

Given question is not complete: find the complete question with attachment

Errol's bike ride can be modeled by the equation,

$d(t)=-\frac{1}{4}t+2$

Slope of the given equation = $-\frac{1}{4}$ which shows the rate of change of distance from Errol's house

Y-intercept = 2, shows the distance of the school from Errol's house

Let the equation that represents the distance of Daniel's home from the school is,

y = mt + b

Since speed of Daniel is equal to the speed of Errol, slopes of both the equations will be same.

Since y-intercept 'b' represents the distance from his home, b = 4

Now the equation will be,

$d(t)=-\frac{1}{4}t+4$

Therefore, the graph representing the Daniel's equation will have a vertical translation by 2 units in the positive direction.
