The hieghts in cm is 50 students are recoreded and used to draw the culmulative frequency graph shown below use the graph to estimate the number of these students witb a hieght above 150 cm

Simplify (a/b - b/a) times (a - a^2/a+b) a - a^2/a=b is a mixed number

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

Ineeeeed this is due tomorrow and i dont know the answer can you find all the exponents
