40 points Dr. Silas studies a culture of bacteria under a microscope. The function b_1 (t)=500〖(1.6)〗^t represents the number of bacteria t hours after Dr. Silas begins her study.

(a) Is this an exponential growth or decay? Explain how you know.

(b) What does the value 500 represent in this situation?

(c) The number of bacteria in a second study is modeled by the function .
What is the growth rate, r, for this equation?
What does the difference of 500 and 800 mean between the two studies?

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

the answer is 1/4
