I want to say it's 45 degrees. I got it by subtracting 180 and 90 then you get 90 and you divide that by 2. The reason I subtracted by 180 is because that's how many degrees a triangle is. I hope it helps.
Her profit per each wood is $5 so her total profit is $25
because
60 divided by 5 is 12, so each wood is 12 dollars
she spent 40 dollars on materials so 40 divided by 5 is 8, so she spent $20 on each piece of wood to paint it because 12(price of wood)+8(cost of materials per wood)= 20
and shes sells them for 25
so 25-20=5
5x5=25
so the answer is $25 profited

Answer:
(a) 100 fishes
(b) t = 10: 483 fishes
t = 20: 999 fishes
t = 30: 1168 fishes
(c)
Step-by-step explanation:
Given
Solving (a): Fishes at t = 0
This gives:
Solving (a): Fishes at t = 10, 20, 30
Solving (c): 
In (b) above.
Notice that as t increases from 10 to 20 to 30, the values of 
decreases
This implies that:
So:
The value of P(t) for large values is:
