What is an equation of the line tangent to the graph of f(x)=x2(2x+1)3 at the point where x=-1? (that's x squared (2x+1)cubed) I'm having trouble finding the derivative:f'(x)which would be the slope (m). No one has answered this question yet.

Ohh thank you-that is what I had overlooked: the fact that the derivative of a constant is = to 0 and that is why I did not need da/dt. Thank You I understand where I went wrong now.

A girl is flying a kite at a height of 320 ft. If the wind blows the kite horizontally at a rate of 15 feet per second away from the girl, at what rate is the girl releasing the string when the length of the string is 400 ft? [kite] <---15 ft/sec . . . . . . . . . . . . 320...

sove for x. 1. 2/3(x+4)=8 round the results to the nearest tenth and then to the nearest hundredth: 2. -57.124/10.104 3. -13.254(-3.145)

hey, do any of you know.. is the story called "the cask of amontillado" or "the cask of the amontillado"? so is there a 'the' or not.. thanks for ur help!
