Your company manufactures dolls each doll requires 2 feet of ribbon for bows how many yards of ribbons will be required to make 600 dolls

400 yd  

Step-by-step explanation:

There are 2 ft of ribbon for 1 doll.

For 600 dolls,

Ribbon = 600 × 2/1

Ribbon = 1200 ft

Convert feet to yards

1 yd = 3 ft

Ribbon = 1200 × 1/3

Ribbon = 400 yd

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
