Justify reasoning a frustum of a pyramid is a part of the pyramid with
two parallel bases. the lateral faces of the frustum are trapezoids. use the
area formula for a trapezoid to derive a formula for the lateral area of a
frustum of a regular square pyramid with base edge lengths b, and b, and
slant height 2. show all of your steps.

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?
