If f(x) = (2x+9)^3, f '(x) = 3(2x+9)^2*(2), or f '(x) = 6(2x+9)^2. Here we used the power rule with chain rule to find the derivative.
Answer:
The original cost of the DVD was $21`.59
Step-by-step explanation:
In order to find this, you first must note that the new price is 88% of the older price. We get this since there was a subtraction of 12%.
Now knowing that, we can divide the new price by the percentage paid and it will give us the original price.
$19/88% = Original Cost
19/.88 = Original Cost
$21.59 = Original Cost
