Starting at an initial position of 100 meters, a person jogs at 5 meters per second for 1 minute forward and then walks backwards at 2 meters per second for 2 minutes. What position does the person end at?

100 + (5 * 60) = 400

400 - (2*120) = 160

end position = 160

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.
