You are designing a hike that starts at the top of the canyon, above sea level. You plan to stop at three locations: •a scenic landmark, which is at sea level •famous boulder, which is below sea level •the bottom of the canyon, which is 600 feet below sea level

Hello your question is incomplete attached below is the complete question and solution as well as the detailed solution

Step-by-step explanation:

The total change in elevation as represented in the number line is

600 - 600 = 0 ( sea level )

below sea level = 0 - 200 = -200 (where the famous boulder is located)

-200 -400 = - 600 feet ( bottom of canyon)

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.

tube or goog would be a great resource to with that question
