How to find the coordinates of the center and length of the radius of the circle?

To find the coordinates of the center of a circle, use an arc to calculate the circumcenter of an imaginary triangle. To find the length of the radius of the circle use a rectangle and divide both sides by π, then multiply both sides by 2.

Hope this helps..

Factor the expression over the complex numbers.<br><br><img src="https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%2B18" id="TexFormula1
AleksAgata [21]

Here we are given the expression:

x^{2}+18

Now let us equate it to zero to find x first,

x^{2}+18=0

Now subtracting 18 from the other side,

x^{2}=-18

taking square root on both sides,

So we will get two values of x as ,

x=3\sqrt{-2}

x=-3\sqrt{-2}

Now we can write square root -1 as i,

So our factors become,

x=3i\sqrt{2}

x=-3i\sqrt{2}

Answer:

The final factored form becomes,

(x+3i\sqrt{2})(x-3i\sqrt{2})

T(x)=1-2x how do you graph this problem
Eva8 [605]

Answer:

Explained

Step-by-step explanation:

The 1 is the y-intercept

The -2 is the slope

First place a point at (0,1)

Then, because it's negative from left to right the graph is decreasing (going lower on the y-axis the farther you go on the x-axis).

Slope is rise over run so the -2 affects how far it goes. So for each value of x that increases by one, a new point will be two units down and one unit right of the previous point. To graph to the left of the y-intercept then you do that backwards where the next point is two units up and one unit left.


Then just draw a straight line connecting all the points.

Factor the four term polynomial by grouping.<br>10x^3-15x^2+6x-9​
goldfiish [28.3K]

Answer:

(5x²  + 3) (2x-3)

Step-by-step explanation:

10x³ - 15x² + 6x - 9   (rearrange)

10x³+ 6x - 15x²  - 9  (group using parentheses)

(10x³+ 6x) - (15x²  + 9)  (factor out 2x from first term and 3 from second term)

2x (5x²+ 3) - 3(5x²  + 3)   (factor out (5x²+3) )

(5x²  + 3) (2x-3)  (answer)

Sliva [168]
You need to set up a fraction. You can use red/blue which would be 5/7. Then, create the second ratio which would be 8/12. And there you will find your answer, which this answer also works for your answering wether you get yes or no.
