A communications tower is located at the top
of a steep hill, as shown. The angle of
inclination of the hill is 77°. A guy wire is to be
attached to the top of the tower and to the
ground, 102 ft downhill from the base of the
tower. The angle formed by the guy wire is 9°.
Find the length of the cable required for the
guy wire.
9°
102 ft
77°
NOTE: The picture is NOT drawn to scale.
length of guy-wire =

How come that I marked ?
Under certain conditions, the number of diseased cells N(t) at time t increases at a rate N'(t) = Aekt, where A is the rate of increase at time 0 (in cells per day) and k is a constant.
(a) Suppose A = 60, and at 3 days, the cells are growing at a rate of 180 per day. Find a formula for the number of cells after t days, given that 200 cells are present at t = 0.
(b) Use your answer from part (a) to find the number of cells present after 8 days.
(a) Find a formula for the number of cells, N(t), after t days.
N(t) =
