What is the measure of the radius of S?

Mathematics

If the question is asking the radius of 'the circle' S, then we need to pick a point on the circle and measure its distance from the center.

In this case, we already have G picked for us and S is the center. So, GS is our radius. It is also written that GS is equal to 6.1. This means the length of the radius of the circle S is 6.1.


Another way of finding it is; as you can see from the picture, YL is a line which goes through the point S or the center. We call those lines a 'diameter'. Diameters also equal to two times of the radius.

So, we know that our diameter is 12.2, when we divide that by 2 we got: \frac{12.2}{2} = 6.1 as our radius.

A diameter is a straight line that crosses a circle and the radius equals the half of this distance. So, in our case, the diameter would be YL which equals 12.2 adn the radius would be:

12.2 / 2 = 6.1


Though you could see it this way, there is still another way of finding the radius. The radius is a straght line that goes from the centre to any point of the circle, which is the same thing as saying that it is half of a diameter:

SG is a line going from the centre (S) to G, which is also equal to 6.1


Hope it helped,

Solve the equation for x by graphing -2x + 3 = -3(-x) - 2
adoni [48]

Answer:

  x = 1

Step-by-step explanation:

There are a couple of ways to solve this. One is to graph the left side of the equation, graph the right side of the equation, and look for the point where those graphs intersect. It is at x = 1. The first attached graph shows this solution.

__

Another method for solving such an equation is to subtract one side from the other and look for the value of x that makes the resulting expression zero.

  (-2x +3) -(-3(-x) -2) = 0

A graphing calculator doesn't need to have this simplified. If it is simplified, it becomes ...

  -5x +5 = 0

So, the graphed line is y = -5x+5. Its x-intercept is x=1, the solution of the original equation. The graph of this is shown in the second attachment.

cricket20 [7]

Answer:

195 ft.

Step-by-step explanation:

I don't have an actual explanation because I simply guessed based on the dimensions and what made the most sense and I got it right. If someone has an explanation as to why it is 195 ft please lmk. Other than that, 195 ft is the correct answer.

Find the value of x.<br> I Need to show the equations please, and show my work
defon

Answer:

15

Step-by-step explanation:

since both equations are set with a right angle, the equation must be equal to 90 degrees. So you set the equation as

13+x+4x+2=90

add the x variables together and the constants separately

15+5x=90

then subtract 15 from both sides.

15+5x=90

-15      -15

5x=75

then divide 5 from both sides.

75/5= 15

so x is 15 :).

F(x)=6x-18 sub in f(x/3), f(x)/3
arlik [135]

These are two separate problems: in the first we will have to substitute in a new value for x into the original equation and in the second we will manipulate the preexisting equation for f(x).

To begin, we will sub in f(x/3). To do this, we will substitute each variable x in the equation (in this case there is only one) with x/3, and then simplify the resulting equation.

f(x) = 6x - 18

f(x/3) = 6(x/3) - 18

To simplify, we should distribute the 6 on the right side of the equation.

f(x/3) = 6x/3 - 18

Now, we can divide the first term on the right side to finalize our simplification.

f(x/3) = 2x -18

Secondly, we are asked to find f(x)/3. To do this, we will take our original value for f(x), and then simplify divide that entire function by 3.

f(x) = 6x - 18

f(x)/3 = (6x-18)/3

This means that we must divide each term of the binomial by 3, so we are really computing

f(x)/3 = 6x/3 - 18/3

We can simplify by dividing both of the terms.

f(x)/3 = 2x - 6

Therefore, your answer is that f(x/3) = 2x - 18, but f(x)/3 = 2x - 6. It is important to recognize that these are two similar, yet different, answers.

Hope this helps!
