An air traffic controller is tracking two planes. To start, Plane A was at an altitude of 970 meters, and Plane B was at an altitude of 1438 meters. Plane A is losing altitude at 17 meters per second, and Plane B is losing altitude at 26 meters per second.
Let x be the number of seconds that have passed. Write a equation for both A and B letting X represent the seconds that have passed. After that write a equation for when both planes are at the same altitude.

(c) a vine called the mile-a-minute weed is known for growing at a very fast rate. it can grow up to 0.5 ft per day. how fast in inches per hour can the mile-a-minute weed grow up to? show your work using the correct conversion factors.

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?
