Kamal's tomato plant is 14.6 inches tall and is growing at a rate of 1.8 inches per week.

Aaron's tomato plant is 9.7 inches tall and

is growing at a rate of 2.4 inches per week.

Let x represent the time in weeks and y

represent the height of the plant in inches.

Which system of equations can Kamal and

Aaron use to determine after now many

weeks their tomato plants will be the same

height?

The biologist has a second culture to examine. she knows that the population of the culture doubles every 15 minutes. after 1 hour and 15 minutes, her assistant found that 80,000 bacteria were present. a) what was the size of the initial population? b) predict the size of the culture at t=3 hours. what was the size of the population at 40 minutes? explain and justify your answers. c) create a graph of the population as a function of time. find an equation that can be used to predict the size of the population at any time t. d) examine the rate at which the bacteria culture is growing. how fast is the culture growing after 1 hour? after 1.5 hours? after 2 hours? use a time interval of h = 0.01 hours to estimate these rates. interpret these rates in terms of the context of the problem situation. how do these three rates compare?
