Maricruz can also run 20 feet in 10 seconds. But if she has a 15 feet head start (when t=0), how far will she be in 30 seconds? In 90 seconds? What is Maricruz's speed (in feet per second)? What rule did you use to find her distance?

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x
