First, divide the total pounds of food eaten by 7 (7 days in a week).
2,100/7 = 300 pounds
Then divide this quotient by the 5 hippos.
300/5 = 60 pounds
Therefore, each hippo eats 60 pounds of food every day.
A^2 = b^2 + c^2 - 2bc cos a
= 11^2 + 5^2 - 2*5*11 cos 40
= 7.86 to 2 DP's
to find the remaining angles use the sine rule:-
a / sin A = b / sin B so
7.857/ sin 40 = 11 / sin B
sin B = 11 sin40 / 7.857 = 0.8999
<B = 64 degrees
so <C = 180 - 64-40 = 76 degrees

The function would be f(x)=11,500-.16xPlug in 4 for x
