7. Assume x and y are functions of t. Evaluate dy/dt for each of the following. (a) y2 - 8x3 = -55, 5= -4,2 = 2, y = 3 (b) = 2, r = 4, y = 2 (e) cell = 2 - In 2 + In 2, 6,2 = 2, y = 0
My answer is shown in the boxes but they're wrong!! I don't know what I did wrong! Please help and show me how to get the right answers.
15. Suppose y= V5x+1 where x and y are functions of t. (a) If dv/dt = 10, find dy/dt when x= 3. 6) If dyldt = 7, find dx/dt when x = 7.

When I plug (0.065) cos (1.78) in the calculator I don't get 0.014 as my answer. Am I missing something? the vertical axis representing position and the horizontal axis representing time. mass on a pring is oven by mass is at the same lecation at 025s Chapter 13 Problem 17P Substitute 0.065 m for A and 0.25 s+T seconds for t in equation (1), 2r (0.25 Ts)) x - (0.065 m)cos 0.s Substitute 0.88 s for T, 2T (0.25+ 0.88...
If you can't answer all that's okay 3 is most important. Then 2, then 5. I need this answered within the hour. I somehow posted this is the wrong category.
