You have a circle that depicts the equator of the earth saw from top (from the artic polar circle). knowing that the equator is in 0º of latitude, the tropic of cancer in 23º of latitude, and the diameter of the circle that depicts the equator is 4 cm, how can i mesure in the same scale where is the tropic of cancer?

In the diagram of circle o, what is the measure of zabc?

B. two events are dependent if the occurrence of one event changes to occurrence of the second event. true or false

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?
