The population of a town is growing according to the differential equation (dy)/(dt)=ky The growth constant, k, is equal to 0.13 year ^-1. The size of the population at the start of the year 2000 was 5 thousand.
Since the population is growing exponentially, the population in year t is given by y=5 e^(0.13 t)

Here, y is measured in thousands and t is measured in years since 2000.

What is the population of the town at the start of the year 2007?

How many years does it take for the population to double?

What will be the size of the population after three doubling times have passed? (That is, after three times the correct answer to part b have passed?)

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130

welcome!

answer: what do you mean

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
