A population of insects grows exponentially, as shown in the table. Suppose the increase in population continues at the same rate.
from the given table
when x=0 , y=20
when x= 1 , y = 30
We use this information to find exponential growth equation
General form of exponential growth is
WE plug in the given values and find out value of a and b
when x=0 , y=20
20 = a
Now we find out b
when x= 1 , y = 30
divide both sides by 20
So exponential function becomes
Now we find the insect population at the end of week 11
We plug in 11 for x
Round the answer to nearest whole number
1730 is the insect population at the end of week 11

Answer:
2 cups of apple juice
Step-by-step explanation:
In order to get one cup of cranberry juice, you would need to add the ratio, 1/4, four times. Since for every 1/4 cup of cranberry juice there is 1/2 cup of apple juice, add 1/2 four times
1/2 + 1/2 + 1/2 + 1/2 = 4/2 = 2 cups
Answer:
Option D) 15%
Step-by-step explanation: 10.5/70= .15
.15x100=15
It would be easier to think it through if instead for 70 we took the number 100. Lets reword it and say what percent of 100 is 38? This would be easy to answer it would be 38% But how you check it is, you take 38 and divide by the total (100) which is .38 then multiply by 100 you will get 38% Same with your equation take the 10.5 and divide by the total amount which is 70 you will get .15 then multiply by 100. the answer will be 15%
