How do I factor 2x^2 + 11x +5

The ranger of the function x2+2x-8is allá

allsm [11]

Answer:

$\mathrm{Range\:of\:}x^2+2x-8:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:-9\:\\ \:\mathrm{Interval\:Notation:}&\:[-9,\:\infty \:)\end{bmatrix}$

Step-by-step explanation:

As the function is

$x^{2} +2x-8$

As we know that domain is the set of input values for which the function is defined.

Therefore,

$\mathrm{Domain\:of\:}\:x^2+2x-8\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

And range is defined as:

The set of the dependent variable for which the function is defined.

As

$\mathrm{For\:a\:parabola}\:ax^2+bx+c\:\mathrm{with\:Vertex}\:\left(x_v,\:y_v\right)$

$\mathrm{If}\:a$

$\mathrm{If}\:a>0\:\mathrm{the\:range\:is}\:f\left(x\right)\ge \:y_v$

$a=1,\:\mathrm{Vertex}\:\left(x_v,\:y_v\right)=\left(-1,\:-9\right)$

$f\left(x\right)\ge \:-9$

Therefore,

$\mathrm{Range\:of\:}x^2+2x-8:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:-9\:\\ \:\mathrm{Interval\:Notation:}&\:[-9,\:\infty \:)\end{bmatrix}$

A worker is constructing a concrete pad that has a radius of 6.3 metres, as shown below. Report a Problem ↻ Reload Image How man

Mariana [72]

The circumference of the pad to the nearest tenth is 39.6 meters

<h3>Formula for calculating the circumference of a circle?</h3>

The circumference of a circle is the arc length of the circle, as if it were opened up and straightened out to a line segment. It is also known as the perimeter of a circle.

The formula for calculating the circumference of a circle is expressed as;

C = 2πr

where

π = 3.14

r is the radius of the circle

Given the following parameters

π = 3.14

r = 6.3m

Substitute to have:

C = 2 * 3.14 * 6.3

C = 6.28 * 6.3

C = 39.564

Hence the circumference of the pad to the nearest tenth is 39.6 meters
