"What is the rate of growth of 20 bacterial if after 4 hours there are 3000" Fill in each step to solve the problem: Using the formula A\:=\:A_oe^{kt}A = A o e k t, let A = , A_oA o = and t = Start by dividing each side by in order to isolate the base Next, rewrite as a logarithm, which turns into Finally, solve for k to get the rate of

1.00213

Step-by-step explanation:

Using the formula provided for the growth

A (t) = A0e^kt where A (t) is the population after time t, A0 is the initial population k is growth constant and t is time

substitute the values given into  the formula

3000 =  20 e^5k

divide both side by 20

3000 /20 = e^5k

150 = e^5k

take natural logarithm of both side

In 150 = 5k

k = In 150 / 5 = 1.00213

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
