Acaterer needs to buy 21 pounds of pasta to cater a wedding. at a local store, 8 pounds of pasta cost $12. how much will the caterer pay for the pasta there

31.5 $

Step-by-step explanation:

First lets se how much 1 pound of pasta costs in the store. We do this dividing the price for 8 pounds over those 8 pounds:

12/8 = $1.5 each pound

As 21 pounds are needed:

$1.5 * 21 = $31.5

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.

hope this

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
