C: Nick's final score is 85 points.
Explanation:
Nick initially scores 90 points on his first turn. On the next, he lost 15 points and lost 10 more. 15 plus 10 would be 25; when subtracted from 90, the difference is 65. On his final turn, he scores 20 points. When added to the current score of 65, the sum is 85 points. Nick's final score is 85 points.
The answer would be 10820
Find the derivative of the curve to find the line slope at the given point
sqrt(xy) + 4 dy/dx = 39
0.5(xy)^(-0.5) * (y + x dy/dx) + 4dy/dx= 0
No need to amplify simply plug in the given point ( 1,9)
0.5 ( 1 * 9)^(-0.5)* ( 9 + dy/dx) + 4dy/dx = 0
Solve for dy/dx
1/6( 9 + dy/dx) = -4dy/dx
9 + dy/dx = -24 dy/dx
-25dy/dx = 9
dy/dx = -9/25
as your question implies , you know the rest of the steps.
