1. An airplane is 5mi from the ground and passes over a remote antenna. when the plane is 10mi from the antenna, the antenna detects that the distance between the antenna and the plane is changing at 240mph
what is the speed of the plane?

2.what is the area of the biggest isos. tri. that is inscribed in a 4in. radius circle?

3. a piece of paper(rectangle) has to have 24 sq. in. of print on it. the margins @ top & bottom are 1 1/2 in. and the margins @ left & right are 1 in. what should the dimensions of the page be for the smallest amount of paper to be used?
