Which form most quickly reveals the vertex?
Jet001 [13]

Answer:

Step-by-step explanation:

A

A will give you the roots (the x intercepts) just by reading the numbers and doing a small adjustment.

x + 1 = 0

x = - 1            So one of the roots is (-1,0)

x + 5= 0

x = - 5           The other root is (-5,0)

A is not the answer.

B

I have graphed B so that you can see that A is true. See below, Even so, B is in standard form and it is not the answer.

C

The answer is C. The vertex is at 2,27

x - 2 = 0

x = 2

The maximum value is located at 27 which is just read.

That point (2,27) is plotted on the graph.

A box that has a length of 2x + 2 and width of x - 2 has a perimeter of 90 centimeters. If the height of the box is x, what is t
tatuchka [14]
First find the value of X from the perimeter given
Perimeter = L*W
90 = 2 ((2x+2) + (x-2))
90 = 4x + 4 +4x - 4
90 = 8x
x = 11.25
Length = 2x + 2
2 (11.25) +2
=24.5
Width = x-2
11.25 -2
=9.25
h =x
= 11.25

Volume = L*W*H
24.5 * 9.25 * 11.25
2549.53 units^3
