The temperature outside changed from 72°F to 42°F over a period of six days. If the temperature changed by the same amount each day, what was the daily temperature change?

5 degrees

Step-by-step explanation:

rate is define as change over time.

So the change is temperatures and time is days.

Rate = (72-42)/6

So, we have 5 degrees drop per day.

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.
