A researcher at the Centers for Disease Control and Prevention is studying the growth of a certain bacteria. He starts his exper
SpyIntel [72]

The population of the bacteria after 7 hours is 230 bacteria.

An exponential function is given by:

y = abˣ

where y, x are variables, a is the initial value of y and b is the multiplier.

Let y represent the population of bacteria after x hours.

Given that he starts his experiment with 200 bacteria, hence

a = 200

The bacteria grow at a rate of 2% per hour, hence:

b = 100% + 2% = 1.02

The exponential equation becomes:

y = 200(1.02)ˣ

After 7 hours:

y = 200(1.02)⁷ = 230

The population of the bacteria after 7 hours is 230 bacteria.

Aleonysh [2.5K]

Answer:

133

Step-by-step explanation:

Snellville

12v+14b = 796

General

14v+12b =738

We need to solve for v and b where v is how many on a van and b is how many on a bus

12v+14b = 796

14v+12b =738

Divide each equation by 2

6v+7b =398

7v+6b =369

Multiply the first equation by 7 and the second equation by -6

7(6v+7b) =7(398)  

42v +49b =2786

-6(7v+6b) =369*-6

-42v -36b = -2214

Add these equations together

42v +49b =2786

-42v -36b = -2214

-------------------------------

     13b = 572

Divide each side by 13

13b/13 = 572/13

b= 44

Now find v

6v+7b =398

6v +7(44)=398

6v +308 = 398

Subtract 308 from each side

6v = 90

Divide by 6

6v/6 = 90/6

v = 15

We want 2 b and 3 v

2b+3v = 2(44)+3(15) = 88+45=133
