Answer to Problem 50CR
The width of the poster is
Explanation of Solution
Given information:
The length and width of the photograph is 6 inches and 4 inches respectively. The length of poster is 51 inches.
Calculation:
It is given that the rectangularphotograph and posterare similar. According to the similarity of quadrilaterals, then their side lengths are proportional.
Let the width of the poster be
Therefore,the width of the poster is

- 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.
