PLEASE HELP ME You place a cup of 205°F coffee on a table in a room that is 72°F, and 10
minutes later, it is 195°F. Approximately how long will it be before the coffee
is 180°F? Use Newton's law of cooling:

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

The measure of an angle is 117°. what is the measure of a supplementary angle?

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^x
