The temperature was 4 at 10: 00pm .it dropped an average of 3 each hour for the next 6 horus. what was the temperature at 4: 00am?

- 14 (negative 14)

Step-by-step explanation:

Time from 10pm to 4am =6 hours

Each hour drop = 3

For 6 hours drop = 6*3 = 18

Temp at 4am = 4-18 = - 14

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 volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
