Question

ap calc question with answer need work!!! help please equation will be attached.

Answer 1

a point moves along a curve Y=\[2x ^{2}+1\] in such a way that the y value is decreasing at the rate of 2 units per second. At what rate is x changing when x=2/3

Answer 2

answer is decreasing 1/3 units/sec

Answer 3

? lol

Answer 4

\[y=2x^2+1\]
\[\frac{dy}{dt}=4x\frac{dx}{dt}\] and you are told that \(\frac{dy}{dt}=-2, x=\frac{2}{3}\) solve for \(\frac{dx}{dt}\)

Answer 5

wouldnt that equal -3/4???

Answer 6

@satellite73 can you help me?

Answer 7

yes dx/dt = -3/4

Answer 8

but the answer is -1/3 so i dont think that was the correct equation for what im looking for.

Answer 9

For the set of information you have provided dx/dt = -3/4.
Go through the question carefully and see if there is any typo or missing info.

Answer 10

x actually equals 3/2 thanks

Answer 11

hahaha

Answer 12

then it is -1/3 indeed.
