The model y = 7.7e0.14x gives the number y (in thousands per cubic centimeter) of bacteria in a liquid culture after x hours. By what factor is the initial number of bacteria multiplied to obtain the number of bacteria after 2 hours?

2x^2+5x+17

your welcome. : )

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
