Easy 20 points for answer! a garage is scheduled to have a temporary gravel floor until the homeowner has the funds necessary to pour a concrete floor. washed gravel is 105 pounds per cubic foot. if the inside dimensions of the garage are as shown in exam figure a6, how much gravel will be required for the floor? round your answer to the next whole ton.

a. 61 tons
b. 84 tons
c. 728 tons
d. 138 tons

B.) 84 Tons

Good luck...

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

it is true
