The marginal average cost of producing x digital sports watches is given by the function c'^overbar(x), where c^overbar(x) is the average cost in dollars. c'^overbar(x) = 1, 200/x^2, c^overbar(100) = 22 find the average cost function and the cost function. what are the fixes costs? the average cost function is c^overbar(x) = the cost function m c(x) = the fixed costs are $

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

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

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).
