Question

Assume that x and y are both differentiable functions of t and find the required values of dy/dt and dx/dt.
y = √x
(a) Find dy/dt, given x = 16 and dx/dt = 7.
dy/dt =

(b) Find dx/dt, given x = 64 and dy/dt = 8.
dx/dt =

Answer 1

y = √x
(a) Find dy/dt, given x = 16 and dx/dt = 7.
dy/dt =

(b) Find dx/dt, given x = 64 and dy/dt = 8.
dx/dt =

Answer 2

\[\frac{dy}{dt}=\frac{1}{2\sqrt{x}}\frac{dx}{dt}\]

Answer 3

hey satelitte:)

Answer 4

put in x = 16 and dx/dt=7 to get your answer!

Answer 5

you get
\[\frac{dy}{dt}=\frac{1}{2\sqrt{16}}\times 7\]

Answer 6

or
\[\frac{dy}{dt}=\frac{7}{8}\]

Answer 7

for the second one put
\[8=\frac{1}{2\sqrt{64}}\times \frac{dx}{dt}\] and solve

Answer 8

i get
\[\frac{dx}{dt}=128\]
