The ordered pair (-4,0) is the solution to the system of equations because it makes both equations true.

Further explanation:

Given equations are:

$2x+y=-8\\x-y=-4$

Given point is:

(-4,0)

In order to check whether the point makes equations true, we have to put the point in equations.

So, putting (-4,0) in first equation:

$2x+y=-8\\2(-4)+0 = -8\\-8+0=-8\\-8=-8$

Putting (-4,0) in second equation

$x-y=-4\\-4-0 = -4\\-4=-4$

We can see that the given point makes both the equations true.

Hence, the ordered pair (-4,0) is the solution to the system of equations because it makes both equations true.

If the circumference of a circle measures 3π cm, what is the area of the circle in terms of π?

g100num [7]

Answer:

the area of the circle is $2.25\pi\ cm^2$ .

Step-by-step explanation:

We have,

Circumference of a circle is 3π cm

Formula of circumference of a circle is given by :

$C=2\pi r$

r is radius of circle

$r=\dfrac{C}{2\pi}\\\\r=\dfrac{3\pi }{2\pi}\\\\r=1.5\ cm$

Area of a circle is given by :

$A=\pi r^2\\\\A=\pi (1.5)^2\\\\A=2.25\pi\ cm^2$

So, the area of the circle is $2.25\pi\ cm^2$ .

How can you tell whether or not a question is a statistical question?

Ray Of Light [21]

A statistical question is one for which you don't expect to get a single answer. Instead, you expect to get a variety of different answers, and you are interested in the distribution and tendency of those answers. For example, "How tall are you?" is not a statistical question. But "How tall are the students in your school?" is a statistical question.

What function to use and how to use it

That's the wrong right triangle to draw. Reading the problem carefully we want this one, figure attached.

So we have the usual 30/60/90 triangle but not to scale. The sides come in ratio 1:√3:2=x:100:hypotenuse. So

x = 100/√3 ≈ 57.735

We add that to our 133.2 for the total height of the Cyclone, 190.935.

Answer: 190.9
