Shelly is a biologist who wants to determine the growth rate of a strain of bacteria. Shelly puts 85 bacteria into a controlled environment and waits 4 hours. When Shelly checks 4 hours later, there are 850 bacteria. What is the hourly growth rate of the bacteria? Enter your answer as a number, rounded to hundredths, like this: 425.36

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

what are you trying to solve here

step-by-step explanation:

it is x equals 3   plese mark me really need it

step-by-step explanation:

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
