Step-by-step explanation:
c=6
Angle A= π/4
Angle B= π/3
Angle C = π - (π/4+π/3)= 5π/12
We want to determine side A.
Using Sine Rule
a=4.39

Answer:
We can divide both sides by 20 and we got:
Now we can appply natural log on both sides and we got:
Now we can divide both sides of the equation by 10 and we got:
So then the aproximate value of k is 0.30986 and rounded would be 0.31
Step-by-step explanation:
We have the following two expression:
We know that the two populations were equal 10 years after the start of the study, so then we can create the following equation:
We can divide both sides by 20 and we got:
Now we can appply natural log on both sides and we got:
Now we can divide both sides of the equation by 10 and we got:
So then the aproximate value of k is 0.30986 and rounded would be 0.31
Answer: the average rate of change is 4.
Step-by-step explanation:
The average rate of change is the slope. Therefore, you must use the following formula for calculate the slope:
As you can see in the table, when x=5, y=-2 and when x=9, y=14. Then the points you must substitute into the formula are:
(5,-2) and (9,14)
Then, you obtain:
