At a canning company the daily production cost, y, is given by the quadratic equation y = 650 – 15x + 0.45x2, where x is the number of canned items. What is the MINIMUM daily production cost?

Question

stamp · Answer

max/min of a parabola ax^2+bx+c is described by$$\frac{-b}{2a}$$

anonymous · Answer

what is the answer then?

stamp · Answer

0.45xx-15x+650

a = 0.45

b = -15

-b/(2a) = -(-15)/(0.90)

15 / 0.9 = 15 * 10/9 = 150 / 9

Plug in x = 150/9

stamp · Answer

The production cost is y. The minimum y value occurs at x = 150/9. So to find the answer to the question, the minimum production value, you plug x = 150/9 and find y = answer

how about this last one.... A ball is kicked upward with an initial velocity of 56 feet per second. The ball's height h (in feet) can be expressed as a function of time t (in seconds) by the equation h = -16t2 + 56t. How much time does the ball take to return to the ground?
