The look-out point of a tower is 60 feet above the ground. a man observes a fountain from the look-out point. the angle of depression to the fountain is 25°.

what is the distance from the base of the tower to the fountain?

round the answer to the nearest foot.

a. 54 ft
b. 66 ft
c. 129 ft
d. 142 ft

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

what shape is

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
