When Sarah passes a ball on a sidewalk to her friend, the ball bounces off at the same angle that it was thrown. Use the figure below to find the angle at which the ball hits the sidewalk and bounces to her friend.

a. 40  if you dont believe me just look at a 40 degree triangle then the pic

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

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.
