Options :
A. The initial number of bacteria is 7.
B. The initial of bacteria decreases at a rate of 93% each day.
C. The number of bacteria increases at a rate of 7% each day.
D. The number of bacteria at the end of one day is 360.
Answer:
C. The number of bacteria increases at a rate of 7% each day.
Step-by-step explanation:
Given the function :
f(x)=360(1.07)^x ; Number of bacteria in sample at the end of x days :
The function above represents an exponential growth function :
With the general form ; Ab^x
Where A = initial amount ;
b = growth rate
x = time
For the function :
A = initial amount of bacteria = 360
b = growth rate = (1 + r) = 1.07
If ; (1 + r) = 1.07 ; we can solve for r to obtain the daily growth rate ;
1 + r = 1.07
r = 1.07 - 1
r = 0.07
r as a percentage ;
0.07 * 100% = 7%

Answer:
D.
Step-by-step explanation:
A multiple is a number that can be divided by another number without a remainder. These are all multiples of 12 because they can all be divided by another number without a remainder.
7 goes into 357 51 times. First you take 35 and see how many times 7 goes into that and that is 5 than you take 7 and see how many times 7 goes into that and that is 1 time so that you take your to answers and you get 51 as the final answer.
