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:
605.69 or if you round it 606 but that's the answer
The 7 in the hundreds place is 10 times bigger than the 7 in the tens place
Part A: 1 solution
Part B:
4(3d −7) = −52
(4)(3d) + (4)(-7)= -52
12d + -28 = -52
12d - 28 = -52
12d - 28 + 28 = -52 + 28
12d = -24
12d/12 = -24/12
d = -2
