Use slope formula
(y1-y2)/(x1-x2)
(16 - -19)/(0 - 4) = 35/-4
The growth factor for the mass of bacteria is 2.8 in 1 week.
Step-by-step explanation:
Step 1:
It is given that the bacteria in the culture increase by 260% per week. Now we assign values to get a better understanding. If there were 1,000 bacteria in the culture at the start of the week there would be 1,000 + 260% at the week's end = 1,000 + 2,600 = 3,600 at the week's end.
Step 2:
To calculate the growth factor, we calculate the difference between the present value and the past value and divide it by the past value.
Here the past value is 1,000 and the present value is 2,600.
Growth factor = 
So the growth factor is 2.6 per week.
Answer: 522.2
Step-by-step explanation:
If you divide the distance in miles by the time you get 95 which in this case is the constant rate therefore you would have to multiply 95 by 5.5 in order to get the answer which would be 522.2.
111,000 because you do 30000+32000+49000.
