Which shows a correct way to determine the volume of the right rectangular prism? A prism has a length of 9 centimeters, height of 1 centimeter, and width of 8 centimeters. 9 + 1 + 8 = 18 Centimeters cubed 2(9 + 1 + 8) = 36 Centimeters cubed 9(3) + 1 = 28 Centimeters cubed 9(8)(1) = 72 Centimeters cubed

9×8×1 = 72

Step-by-step explanation:

The formula for the volume of a right rectangular prism is V = w×l×h

Therefore, 9×8×1 = 72 is correct

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.
