natka813 [3]

Answer:

Step-by-step explanation:

Area of a square equals to the square of its side, therefor the side of a given area for a square is the square root of the area.

$A = a^{2}\\a = \sqrt{A}\\a = \sqrt{110} = 10.48 ft$

from a window 20 feet above the ground, the angle of elevation to the top of another building is 35 degrees. The distance betwee

NISA [10]

Answer:

56.4 ft

Step-by-step explanation:

The tangent of the angle relates the opposite side (height above the window) to the adjacent side (distance between buildings) in the right triangle that models this geometry.

Tan = Opposite/Adjacent

tan(35°) = (height above window)/(distance between buildings)

height above window = (52 ft)tan(35°) ≈ 36.4 ft

Added to the window height of 20 ft, the height of the other building is ...

20 ft + 36.4 ft = 56.4 ft

What is the range of f(x) = 3x + 9?

ziro4ka [17]

Answer:

The range is all real numbers.

Step-by-step explanation:

The function shown is a line (and not a horizontal line).

The range is all the y's on the graph or all the y's that can be generated by the equation of the function.

f(x) = 3x + 9

You could put ANY, literally any, number in place of the f(x) and be able to calculate an x for it. Looking at the graph of this line, you could go up and down the y-axis to infinity in either direction, and the graph of the line would be there.

The range is All Real Numbers.
