A population of bacteria is 8500 on Day 1, 9350 on Day 2, and 10285 on Day 3.
11111nata11111 [884]

Answer:

<em>The population on 30th day will be </em><em>134836</em><em>.</em>

Step-by-step explanation:

This is a case of exponential growth. The general form of exponential function is,

y=ab^x

where, a and b are constants.

The data points from the question are (1,8500),(2,9350),(3,10285)

Putting the values in the function,

for x=1, y=8500

8500=ab  ----------1

for x=2, y=9350

9350=ab^2  ------2

Dividing equation 2 by 1,

\Rightarrow \dfrac{ab^2}{ab}=\dfrac{9350}{8500}=1.1

\Rightarrow b=1.1

Putting the value of b in equation 1,

\Rightarrow a=\dfrac{8500}{1.1}=7727.27

Now the function becomes,

y=7727.27(1.1)^x

Putting x=30, we get

y=7727.27(1.1)^{30}=134836.2\approx 134836
