A factory produces shirts. The cost, C, in Fijian dollars (FJD), of producing x shirts can be
modelled by
C(x) = (x - 75)2 + 100.
Find the cost of producing 70 shirts.

10 you would take 50/ .2

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140

it is 32.5

i hope i could u.
