<span> y^2 = (3x + 1)^3 / 9x + 2
2*y*(dy/dx)=(9</span>(3x + 1)^2*(9x + 2) -((9*(3x + 1)^3))/ ((9x + 2)^2)
(dy/dx)=(9(3x + 1)^2*(9x + 2) -((9*(3x + 1)^3))/ (2*y*(9x + 2)^2)
(dy/dx)=(9(3x + 1)^2*(6x + 1))/ (2*y*(9x + 2)^2)
answer
A
Answer:
10%
Step-by-step explanation:
You can solve this equation by back-solving. Pick a random percent that you would think is close and convert it to decimal, then multiply it by the original price and subtract that from the original price.

Relevance Best Answer: <span>Something is wrong with the question.
$78 / 612 hours ≈ $0.13 per hour (in other words, less than 13 *cents* per hour).
To figure the hourly rate, take the total pay and divide by the hours.
For example, if it was $78 for *6* hours, it would be:
78 / 6 = $13 per hour.
Or more likely, it was $78 for *6½* hours:
78 / 6½
= 78 / 13/2
= 78 x 2/13
= 78/13 x 2
= 6 x 2
= $12 per hour</span>
