The linear inequalities that will limit the solution region in a linear programming problem are called the origin.

Explanation:

The x-axis is a horizontal line, and it is perpendicular to the y-axis. The origin is called the convergence of the two axes. This property allows multiplying a term or terms into a polynomial.
The origin is a starting point, and in mathematics, the origin can also be said as the starting point.
The co-ordinates for every other point are based on how far from the origin that point is. x and y are equal to zero at the origin and cross the x-axis and y-axis.

Find an equation of the sphere with center (2, −10, 3) and radius 5. $$25=(x−2)2+(y−(−10))2+(z−3)2 use an equation to describe i

lana66690 [7]

In the $x,y$ plane, we have $z=0$ everywhere. So in the equation of the sphere, we have

$25=(x-2)^2+(y+10)^2+(-3)^2\implies(x-2)^2+(y+10)^2=16=4^2$

which is a circle centered at (2, -10, 0) of radius 4.

In the $x,z$ plane, we have $y=0$ , which gives

$25=(x-2)^2+10^2+(z-3)^2\implies(x-2)^2+(z-3)^2=-75$

But any squared real quantity is positive, so there is no intersection between the sphere and this plane.

In the $y,z$ plane, $x=0$ , so

$25=(-2)^2+(y+10)^2+(z-3)^2\implies(y+10)^2+(z-3)^2=21=(\sqrt{21})^2$

which is a circle centered at (0, -10, 3) of radius $\sqrt{21}$ .

The length of a rectangle is 2 foot less than 3 times its width. Find the the dimensions of this rectangle if the area is 96 squ

Xelga [282]

For example,area = a, length = l, width = w
First we write two equations. The easier equation is the area equation, which we know to be
a = l x w
So that the first equation is :
96 = l x w 

we make the second equation of the following statements :
The length of a rectangle is 2 foot less than 3 times its width.
so it becomes :
l = 3w - 2

To solve, we can use the substitution method.

$96 = l \times w\\96=(3w-2) \times w\\96=3w^{2}-2w\\3w^{2}-2w-96=0~~~~~~[now\ factor\ the\ equation]\\ (3w+16)(w-6)=0$

$3w+16=0\\3w=-16\\w= -\frac{16}{3}~~~~\Rightarrow~~~answer\ doesnt\ make\ sense\ , negative\ width.
$

$w-6=0\\\boxed{w=6~~~~~~~\Rightarrow~~~~positive\ answer\ for\ width\ makes\ sense }
$

So if our width is 6, Now substitute the value of w = 6 into equation 2 

$l=3w-2\\l=3(6)-2\\l=18-2\\l=16$

So "w" = 6 and "l" = 16, and if we multiply them together, we get the correct area, 96. So our dimensions are 6 by 16.

For which situations is it appropriate to use a sample? Select three options.

maw [93]

Answer:

B C D

Step-by-step explanation:

We use samples when using an entire population is not feasible.

It is not reasonable to ask every pick-up truck driver what they want their next purchase to be; there are too many owners of pick-up trucks. This means we should use a sample.

Many people drive a highway that connects two large cities. It is not reasonable to survey every person that drives it, so we should use a sample.

On a busy road, we may have many pedestrians; this means we should use a sample instead of the entire population.

Calculus help??????

katen-ka-za [31]

$f(x)=\ln x\implies f'(x)=\dfrac1x$
$g(x)=x^2-1\implies g'(x)=2x$

You have $2x^2>1$ for all $x\ge1$ , and dividing by $x$ gives $2x>\dfrac1x$ , or $g'(x)>f'(x)$ . By the racetrack principle, then, it follows that $g(x)>f(x)$ .
