The size of bacteria colony, y, in millions of cells, after x days, is represented by the following function: y=9^5x

The number of days to reach a count of 243 million can be found by solving the linear equation ___x = ___
.

It will take bacteria___ day(s) to reach a count of 243 million.

It takes half a day for the bacteria to reach 243 million. The linear equation is solved for x= 0.5 or x=1/2.

Step-by-step explanation:

The given linear function is   .

where,

To find the number of days to reach the size of 243 million :

Substitute y=243 in the linear equation to get the number of days x.

⇒ 243 =

⇒ 243 can also be written as

⇒ =  

⇒   =  

⇒ The powers in both sides are 5 and 10x . The bases in both sides are same.

⇒ Comparing the power on both sides to solve for x value.

⇒ 10x = 5

⇒ x = 5/10

x= 1/2

x= 0.5

It takes half a day for the bacteria to reach 243 million

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
