At Ralph’s fruit stand ½ pound of grapes cost 90 cents. You want to buy 5 pounds of grapes. How much will they cost? 1. What are the two possible rates for this problem? 2. Show each rate as a unit rate. 3. What does each unit rate tell you? 4. Which unit rate will help you solve the problem? 5. If it costs 180 cents to buy 1 pound of grapes, how much will 2 pounds cost? 4 pounds? Complete the table below. Then, describe the pattern you see in the chart. POUNDS OF GRAPES COST IN CENTS 1 180 2 3 6. Since you know the unit price, write a number sentence for the cost of five pounds of grapes. Write an equation for the cost of any pounds of grapes.

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

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

i think the answer is c sorry if it's wrong

the answer is about 24 dollars
