james is studying newly discovered bacteria in a petri dish. at time t = 0 there is 57 bacteria found in the dish. this bacteria is growing at a 12% rate every hour.

a. write the function f(x) that represents the amount of bacteria found each hour.

b. explain what x represents.

c. explain what f(x) represents.

d. if it continues at this rate, how much bacteria will be in the dish after 8 hours.

The amount of bacteria each hour is 63.84 and

The amount of bacteria after 8 hours is 141.12

Step-by-step explanation:

Given as :

The initial number of bacteria = i = 57

The rate of grow of bacteria = r = 12%

The number of bacteria after 1 hours = f

Let The number of bacteria after 8 hours = n

Now, According to question

The number of bacteria after n hours =  initial number of bacteria ×

Or, The number of bacteria after 1 hours = i  ×

Or, f =  57 ×

Or, f =  57 ×

Or, f =  57 × 1.12

Or, f =  63.84

So,The number of bacteria after 1 hour  = f = 63.84

Hence, The number of bacteria after 1 hours is 63.84  Answer

Again

The number of bacteria after n hours =  initial number of bacteria ×

Or, The number of bacteria after 8 hours = i  ×

Or, n =  57 ×

Or, n =  57 ×

Or, n =  57 × 2.4759

Or, n =  141.12

So,The number of bacteria after 8 hours = n = 141.12

Hence, The number of bacteria after 8 hours is 141.12  Answer

i think it is 18
