Marco is studying a type of mold that grows at a fast rate. he created the function f(x)=345(1.30)^x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number.

-  (1) 1.30 represents the rate of growth of mold spores per week.

(2)There are 985 mold spores in 4 weeks .

Explanation:-

The exponential function is given by , where C is the initial amount , r is the rate of growth and x is time period.

The given function is , where  initial number of mold spores= 345 and x is the time in weeks.

Now,

Here we can see that r = 0.30 =30%

Therefore ,1.30 represents the rate of growth of mold spores per week.

Now, mold spores after 4 weeks  i.e. at  x=4

There are 985 mold spores in 4 weeks.

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

the answer is 175.4379
