Answer:

$65

Step-by-step explanation:

Given

Percentage discount = 20%

Equivalent amount saved = $13

Let the original price of the product be x

To get x;

20% of x  = 13

0.2x =  13

0.2x  = -13

0.2 = 13

x = 13/0.2

x = $65

Hence the original price of the product is $65

Find f'(0) for the function. Provide an exact answer (meaning no rounding is involved).
NARA [144]

The derivative of a function like this is computed with the following formula:

(e^{f(x)})' = e^{f(x)}\cdot f'(x)

So, in your case, we have

f'(x) = e^{x^2+17x} \cdot (2x+17)

When you evaluate this at 0, you have

f'(0) = e^0 \cdot 17 = 1\cdot 17=17
