Please i need help i have no clue how to do this... if you get me the right answer ill medal and fan you! ...
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) = 4000+50N+100E

b) Express the rate of change of the height of the car with respect to time in terms of v.

wait I lost the a) answer, I need it back!

anonymous · Answer

the answer to a is (50-100)/sqrt(2)

anonymous · Answer

that was the "run" vector value,  so isn't the rate of change just rise  (h(N,E)/
                                                                                    0ver run   a.) answer

anonymous · Answer

b is in terms of v?

anonymous · Answer

???  thinking that a.) is a distance value and v is distance/time then we need to express it so the distance values will cancel and we can get answer in terms of time....  mmmmmm...

i dont think so...

sorry my brain is wiped, gotta crash...  will check in AM  g'nite :(
