A whale-watching tour boat has finished viewing a whale and is returning to shore, moving 77 kilometers per hour. The whale coincidentally starts swimming away from the boat at the same time, moving in the exact opposite direction at a rate of 25 kilometers per hour. How long will it be before the whale and the boat are 6 kilometers apart?

Select the best attribute for the angle pair formed by two parallel lines intersected by a transversal.

Factor completely. 4p^2 + 36p + 81 express the answer in the form (ap + b)^2

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
