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 best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
