We are told that a population of insects grows exponentially and we are given a table of data about insect population growth. We are asked to find population of insects at the end of week 11.
The initial insect population is 20 and at the end of 1st week population increases to 30.
Let us find growth percentage of insect population,
We can see that insect population is growing at rate of 50% per week.
Now let us write an exponential function for our population.
, where P(w) represents population at the end of w weeks.
Let us substitute w=11 in our function to find insect population at the end of 11 weeks.
Therefore, population of insects at the end of 11th week will be 1730.
Answer:
63/8
Step-by-step explanation:
3 1/2 = 7/2
4 1/3 = 13/3
The statement "y varies inversely as x means that when x increases, y decreases by the same factor. In other words, the expression xy is constant :
x*y = k
k is the variation constant.
Just substitute the values in that formula :
16*9 = 4*4*9 = 172.
So the variation constant here is 172.
In order to find the equation of variation of y, you should change the equation i gave you.
y = k/x
y= 172/x
Hope this helps !
