A bird sitting on top of a stop sign notices a piece of food on the ground, 11 ft from the base of the stop sign. If the bird has to look
down at a 39° angle of depression in order to see the piece of food,
what is the approximate distance from the bird to the food?
(Assume the stop sign is at a right angle to the ground.)
sin 39° = 0.63
cos 39° = 0.78
tan 39° = 0.81
A. 8.58 ft
C. 14.10 ft
B. 13.58 ft
D. 17.46 ft

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

no one knows lol
