By looking at the table, you can see that we have an x
that is paired with two different y's so this does not fit the
definition of a function which states that each x must
be paired with exactly one y.

Step-by-step explanation:
by using pythagorean theorem:
XW²+XY²=
(2×6.4)² + 9.6² =
12.8²+9.6²=
163.84 + 92.16= 256
WY²= 16²= 256
so, XW²+XY²=WY²
=> the WXY is a right triangle, and X is a right angle.
so XY is perpendicular to XW as the diameter of circle Z.
and XY is tangent to circle Z

Step-by-step explanation:
Using S = rA, where S is arc length, r is radius and A is angle(in radians).
Comparing: S = 11π, A = 180° = π
=> 11π = rπ
=> 11 = r
Required radius is 11 unit

Find the area of the shaded region.
800
5 cm
A=[?] cm2
Enter a decimal rounded to the nearest tenth.
Enter
Answers
If the radius of the circle is 5 cm and central angle is 80° then the area of the shaded region is 61.06.
Given that the radius of the circle is 5 cm and central angle is 80°.
We are required to find the area of the shaded region.
The area of the shaded region is basically the difference between the area of the whole circle and the area of the arc which is not shaded.
Area of circle=π[tex]r^{2}[/tex]
=3.14*25
=78.5 [tex]cm^{2}[/tex]
Area of the arc =([tex]r^{2}[/tex]Θ)/2
=(25*80π)/2*180
=(25*80*3.14)/360
=6280/360
=17.44
Area of the shaded region=78.5-17.444
=61.056
After rounding off to the nearest tenth it will be as under:
=61.06
Hence if the radius of the circle is 5 cm and central angle is 80° then the area of the shaded region is 61.06.
