The relative growth rate for a certain type of bacteria population is 85% per hour. A small culture has formed and in just 2 hou
harkovskaia [24]
Let us assume the initial number of bacteria in the culture = xAfter 1 hour,The number of bacteria = 185x/100                                      = 1.85xAfter 2 hours,The number of bacteria = (185 * 1.85x)/100                                       = 3.42xSo3.42x = 12500x = 12500/3.42   = 3654.97   = 3655From the above deduction, we can conclude that the initial number of bacteria in the culture is 3655.

If your starting salary were $40,000 and you received a 3% increase at the end of every year for 15 years, what would be the tot
Dmitry [639]

T = 40000 + 40000(1.03) + 40000(1.03)^2 + ... + 40000(1.03)^15


Multiply the above equation by 1.03 giving


1.03(T) = 40000(1.03) + 40000(1.03)^2 + 40000(1.03)^3 + ... + 40000(1.03)^15 + 40000(1.03)^16


Now subtract the first equation from the second to give


0.03T = 40000(1.03)^16 - 40000


0.03T = 40000(1.03^16 - 1)


0.03T = 24188.26


T = 24188.26 / 0.03 = $806275.25
