Abuilder wishes to construct a ramp 21 feet long that rises to a height of 5 feet above level ground. what angle should the ramp make with the horizontal? decimal approximations will be marked incorrect. symbolic trigonometric expressions such as arctan(5) are accepted. 1/ 5 21 α cos radians

Given f(x) = 17-x^2what is the average rate of change in f(x) over the interval [1, 5]?

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
