Aculture started with 4,000 bacteria. after 2 hours it grew to 4400 bacteria. predict how many bacteria will be present after 13 hours round your answer to the nearest whole number.

7436

Step-by-step explanation:

y = ab^x

a = 4000

b = 4400/4000 = 1.1

x = t/2 

4400 = 4000e^2k 

e^2k = 1.1 

k = ln 1.1/2 = .0477 to 4 dp 

N(13) = 4000e^(13*.0477) = 7436

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.
