Bernard is helping his mom carry groceries. The bag he is carrying has everything they need to make spaghetti for dinner tonight. It has 16 ounces of spaghetti, 32 ounces of tomato sauce, and 1 pound of ground beef. How many pounds does his bag of groceries weigh? Pounds

Total pounds= 4 pounds

Step-by-step explanation:

Giving the following information:

16 ounces of spaghetti

32 ounces of tomato sauce

1 pound of ground beef.

We need to use the following proportion:

1 pound= 16 ounces

Total ounces= 16 + 32= 48 ounces

Total pounds= (48/16) + 1

Total pounds= 4 pounds

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
