Answer: The correct answer is Choice C 29.3%.
To find the percent change, we place the amount of change over the original amount.
The change is: 26450 - 20450 = 6000
Now, we can write our fraction and change it to a percent.
6000 / 20450 x 100 = 29.3%
Answer:
12
Step-by-step explanation:
f(x) = -x^3 + x^2
Let x = -2
Evaluate the expression
f(-2) = -(-2)^3 + (-2)^2
= - (-2)*(-2) * (-2) + ( -2) * (-2)
= -(-8) + ( 4)
= 8 + 4
= 12
