Plz help Can you plot the data ! 9b) write the equation of your best fitting line.

9c)use your to determine how well you would do if for 4 hours

9b y= 15.109t + 56.4

9c 116.836 in 4 hours

Step-by-step explanation:

I used a regression calculator for the first one.

I multiplied 15.109 and 4 because t is the time.

add 56.4

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.

the answer is c just got it on ed
