I hope that someone help me in solving these application. (plz, I want to solution step by step)..
A Cassna plane takes off from an airport at sea level and it's altitude (in feet) at time t (in minutes) is
given by h= 2000 ln (t+1) .
find the rate of climb at time t = 3min .
If the variable sound power W is given by W = T^2 + t + 1 , Find the rate of change of the sound
pressure P , at time t= 3 s .
A computer is programmed to inscribe a series of rectangle in the first quadrant under the curve of y=e^-x
What is the greatest area of the largest rectangle that can be inscribed ? .
A point moves along the x axis so that it's position x at time t is specificed by the function x(t)= t^3-8t+8 .
determine the following :
a- the acceleration at times when the velocity is zero .
b- the average velocity over the time interval (0,6) .
I'm sorry for all this quastion ..
