What are the real or imaginary solutions of the polynomial x^3=9x

dem82 [27]

Hello from MrBillDoesMath!

Answer:

x = 0, +\-3

Discussion:

x^3 = 9x => subtract 9x from both sides

x^3 - 9x = 0 => factor x from both terms

x(x^2-9) = 0 => x = 0 or x^2 - 9 = 0

x = 0, +\-3

Thank you,

MrB

What is the average rate of change for the function f(x)=3(0.25)^x over the interval -2 ≤ x ≤ 0

diamong [38]

Answer:
-22.5

Explanation:
Use the average rate of change equation
f(b)-f(a) / b-a
f(b) = f(0) = 3(.25)^0 = 3
f(a) = f(-2) = 3(.25)^-2 = 48

(3-48)/ 0-(-2)
(-45) / 2
-22.5

Tyler baked 702 cookies. He sold them in boxes of 1i. After selling all the boxes of cookies for the same amount each he earned

ikadub [295]

Answer:

$3.5

Step-by-step explanation:

We have been given that Tyler baked 702 cookies. He sold them in boxes of 18.

First of all we will find the number of boxes of cookies by dividing 702 by 18.

$\text{Number of boxes of cookies}=\frac{702}{18}$

$\text{Number of boxes of cookies}=39$

We are told that after selling all the boxes of cookies for the same amount each he earned $136.50. To find the cost of each box we will divide 136.50 by 39.

$\text{The cost of one box}=\frac{136.50}{39}$

$\text{The cost of one box}=3.5$

Therefore, the cost of one box of cookies is $3.5.
