Len [333]

Answer:

See below.

Step-by-step explanation:

The graph of the quadratic equation is a parabola or u shaped graph. It has a vertex at (-1,-3) since h=-1 and k=-3 in the vertex form. It is also facing down since the leading coefficient is negative.

Find the volume of this cone.<br> Use 3 for TT.<br> 5in<br> Tr2h<br> 3<br> 8in<br> V<br> V ~ [?]in3

LuckyWell [14K]

Answer:

50 in ^3

Step-by-step explanation:

V = 1/3 pi r^2 h

We know that pi = 3

the diameter is 5 so the radius is 1/2 the diameter of 5/2 = 2.5

The height is 8

V = 1/3 ( 3) ( 2.5)^2 ( 8)

V = 50 in ^3

The area of a rectangle is 24 square centimeters. The length (X), in centimeters of the rectangle is given by the equation x2 +

Allisa [31]

The length of the rectangle is 3 cm

<h3>Applications of Quadratic equations</h3>

From the question, we are to determine the value of the length of the rectangle

To find the length of the rectangle, we will determine the value of x in the given equation

The given equation is

$x^{2} + 5x =24$

This can be written as

$x^{2} +5x -24 =0$

Factorizing

$x^{2} +8x - 3x -24 = 0$

$x(x+8) -3(x+8)=0$

$(x-3)(x+8)=0$

Then,

$x-3 = 0$ OR $x + 8 = 0$

x = 3 OR x = -8

Since, the length of the rectangle cannot be negative, the value of x is 3.

Hence, the length of the rectangle is 3 cm.
