いろいろ y=a(1+r)^t what is r 244065-What is y=a(1+r)^t
In a labatory, a culture increases from 30 to 195 organisms in 5 hours What is the hourly growth rate in the growth formula y=a(1r)^t y=a(1r)^t The problem gives us y as 195 a as 30 t as 5 195=30(1r)^5 195/30 = (1r)^5 65 = (1r)^5 65^(1/5) = 1r 65^(2) = 1r 65^(2) 1 = r 1454 1 = r 0454 = r 454% = rQuestion An equation for the depreciation of a car is given by y = A(1 – r)t , where y = current value of the car, A = original cost, r = rate of depreciation, and t = time, in years The value of a car is half what it originally cost The rate of depreciation is 10% Approximately how old is the car?(ii) At what time t is the displacement vector from point Q to the point on the line P, QP, orthogonal to the line L?
