Dr. Silas studies a culture of bacteria under a microscope. The function b2(t)=1200(1.8) represents the number of bacteria t hours after Dr. Silas begins her study. (a) What does the value 1200 represent in this situation?

(b) What does the value 1.8 represent in this situation?

(c) The number of bacteria in a second study is modeled by the function b2(t)=1000(1.8)t .
What does the value of 1000 represent in this situation?
What does the difference of 1200 and 1000 mean between the two studies?

Someone answer this asap rn for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
