The chords intersect at point U. What is the value of y?

Answer:

6 centimeters.

Step-by-step explanation:

For chords that intersect inside a circle, we have the intersecting chords theorem, which states that the product of both colinear segments are equal to the products of the intersecting colinear segments meaning that:

Segment 1*segment2 =segment3*segment4

So 12*4=8*x

We just have to clear x from the equation to get the value of X:

Segment 1*segment2 =segment3*segment4\\12*4=8*x\\x=\frac{12*4}{8}\\ x=6

So the segment Y measures 6 cm.

we know that

<u>The intersecting chords theorem</u> states that the products of the lengths of the line segments on each chord are equal

so

in this problem

RU*UT=QU*US

we have

RU=12\ cm\\UT=4\ cm\\QU=8\ cm\\US=y\ cm

substitute the values

12*4=8*y

48=8*y

y=6\ cm

therefore

<u>the answer is </u>

y=6\ cm

So hmm notice the picture below

you have the center, and a point on the circle... all you need is the radius

\bf \textit{distance between 2 points}\\ \quad \\&#10;\begin{array}{lllll}&#10;&x_1&y_1&x_2&y_2\\&#10;%  (a,b)&#10;&({{ 1}}\quad ,&{{ -2}})\quad &#10;%  (c,d)&#10;&({{ 3}}\quad ,&{{ -4}})&#10;\end{array}\qquad &#10;%  distance value&#10;d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}\leftarrow  r

then use that radius in the circle's equation

\bf (x-{{ h}})^2+(y-{{ k}})^2={{ r}}^2&#10;\qquad center\ ({{ h}},{{ k}})\qquad&#10;radius={{ r}}

Maria is comparing the prices of two window cleaning companies. Company A charges $6 per window and an additional $12 as service
Pani-rosa [81]
Part A: 6w + 12 = 5w + 15

Part B: 6(8) + 12 = 5(8) + 15
48 + 12 = 40 + 15
60 = 55 = Company B equals $55 which is less than $60

Part C: $5 is saved because of the amount of money.
Hope this helps :)
