Answer: -9 1/4.
Step-by-step explanation:
A sector of a circle is <span> the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor </span>sector<span> and the larger being the major </span>sector<span>.
</span><span>The area A of a circle with radius r is given by A = πr2. The circumference C of that same circle is given by C = 2πr. But these are the formulas for the entire circle. Sometimes you will need to work with just a portion of a circle's revolution, or with many revolutions of the circle.</span><span>

The values of x and y are 8 and 0 respectively.
<em><u>Explanation</u></em>
As 'p' is located at (0,0) and 'r' is located at (-12,0) , that means both 'p' and 'r' are on the x-axis. So point 'q' will be also on the x-axis , and 'q' is located at (x,y)
So, the value of y will be 0. That means the co ordinate of point 'q' is (x, 0)
Now, using the Distance formula, length of 'pq' 
and length of 'pr' 
Given that, pq : pr =2/3
So....

Thus, the values of x and y are 8 and 0 respectively.
Answer:
-9
Step-by-step explanation:
The applicable exponent rule is ...
a^b·a^c = a^(b+c)
___
For the y factor, ...
y^-13 · y^4 = y^(-13+4) = y^-9 . . . . . exponent of -9
