If u= and v=<3cos45degree,3sin45degree> find the direction of u+v. Put in degrees and round to the nearest tenth.

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

Use the distributive law to multiply. 3(4x + 5y + 6)

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?
