T = (700) / t^2+4t+10

where t is the time in hours. Find the rate of change of T with respect to t at each of the following times.

a. t=1

b. t=3

c. t=5

d. t=10

** i'll be able to do the others on my own if you please explain step by step how to do at least one of these. I have now idea where to start. SOMEONE PLEASE HELP ME A.S.A.P ! :(

THANK YOU.

**Vipster**, Sunday, October 18, 2009 at 9:43pmyou gotto differentiate the function

so if

T= 700* (t^-2) + 4t + 10

dT/dt = 700* (-2) (t^ -3) +4

now just plug in t = 1 in the above

same with the others too
