Answer:
<em>Initial population: 222 fish</em>
<em>After 7 years: 871 fish</em>
Step-by-step explanation:
Initial population size:
Let t=0
∴P(0)=
=
=
=222 fish
After 7 years:
Let t=7
∴P(7)=871 fish

Answer:
44ft
Step-by-step explanation:
The formula for circumference is 2 * π * radius and in this case we want to use 3.14 for π and so we do 2 x 3.14 x 7 because the radius is half of the diameter (14) and once you do that you end up getting 43.96 and once you round you get 44ft so you are correct.
Answer:
x = 16 when y = 40
Step-by-step explanation:
as y is directly proportional to x:
y = x
y = k x .........k is here constant.
15 = k * 6
k = 15/6
k = 5/2
Here constant, k is (5/2)
So when y = 40
y = k x
40 = (5/2)x
x = 40(2/5)
x = 16
