Answer 1

related rates, calculus problem,
use a^2+b^c=c^2
c = 17
a^2+b^2=289
take the derivative with respect to t

Answer 2

Can you follow precal's instruction?

Answer 3

I've tried this 3 times and I've gotten 4.8 but its not correct

Answer 4

Show me how you take derivative:

Answer 5

i've done
a=9
b= square root 208
c = 17
da/dt=?
db/dt=-3
dc/dt=0
a(da/dt)+b(db/dt)=c(dc/dt)
9(da/dt)+ square root 208 * (-3) = 17 * 0
9(da/dt) = 43.2666
da/dt = 4.8

Answer 6

How about try: - 4.8

Answer 7

that isn't right either

Answer 8

Sometimes just some round off!

Answer 9

There's nothing wrong with your logic and calculation !

Answer 10

Did you try 4.81 (or 4.807)?

Answer 11

@precal What's your result?

Answer 12

oh I did not even do the problem at all. But give me a minute
