A car is driving northwest at v mph across a sloping plain whose height, in feet above sea level, at a point N miles north and E miles east of a city is given by: h(N,E)=4750+75N+100E.
At what rate is the height above sea level changing with respect to distance in the direction the car is driving? R= 75sin45 - 100cos45.
I have to express the rate of change of the height of the car with respecto to time in terms of v...
