A man observes a balloon at a 62angle of elevation. He knows the balloon is hovering directly above a point on the ground, 900 feet to the east, as shown in the figure below. If the man is 6ft tall, what is h, the altitude of the balloon, to the nearest foot?

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola

differentiate (x^14(x^-2)^4with respect to the variable

the parentheses don't balance in your input.

differentiate 0 with respect to

the final answer is

0

hope this

triangle eg 7.5 × cos "a" or 7.5 × sin "b" or 6 tan"a"
