Aculture started with 3,000 bacteria. after 8 hours, it grew to 3,300 bacteria. predict how many bacteria will be present after 12 hours. round your answer to the nearest whole number.

Step-by-step explanation:

In this problem we have a exponential function of the form

where

x is the time in hours

y is the numbers of bacteria

a is the initial value

b is the base

r is the rate of growth

b=(1+r)

we have that

For x=8, y=3,300

substitute in the exponential function

solve for b

Find the value of r

The equation is equal to

For x=12 hours

substitute the value of x in the equation

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
