Nady [450]
Answer:
![\{(-6, -4), (4, -8), (-6, 9), (1, -3)\}](https://tex.z-dn.net/?f=%5C%7B%28-6%2C%20-4%29%2C%20%284%2C%20-8%29%2C%20%28-6%2C%209%29%2C%20%281%2C%20-3%29%5C%7D)
Step-by-step explanation:
Given
![\{(5, -9), (6, -6), (-3, 8), (9, -6)\}](https://tex.z-dn.net/?f=%5C%7B%285%2C%20-9%29%2C%20%286%2C%20-6%29%2C%20%28-3%2C%208%29%2C%20%289%2C%20-6%29%5C%7D)
![\{(-6, -4), (4, -8), (-6, 9), (1, -3)\}](https://tex.z-dn.net/?f=%5C%7B%28-6%2C%20-4%29%2C%20%284%2C%20-8%29%2C%20%28-6%2C%209%29%2C%20%281%2C%20-3%29%5C%7D)
![\{(1, -1), (-5, 7), (4, -9), (-9, 7)\}](https://tex.z-dn.net/?f=%5C%7B%281%2C%20-1%29%2C%20%28-5%2C%207%29%2C%20%284%2C%20-9%29%2C%20%28-9%2C%207%29%5C%7D)

Which is not a function
An ordered pair is represented as:
![\{(x_1,y_1),(x_2,y_2),(x_3,y_3),..........,(x_n,y_n)\}](https://tex.z-dn.net/?f=%5C%7B%28x_1%2Cy_1%29%2C%28x_2%2Cy_2%29%2C%28x_3%2Cy_3%29%2C..........%2C%28x_n%2Cy_n%29%5C%7D)
However, for the ordered pair to be a function; all the x values must be unique (i.e. not repeated)
<em>From options (a) to (d), option (b) has -6 repeated twice. Hence, it is not a function.</em>
Maybe because you're finding the "difference" between the two numbers. We could also question why the answer to an addition problem is called sum.
Well, 'sum'body said that's what they should be called a long time ago, that's why we're using that term to call them now.
5 with some change left over.
The form which should be used when you know the slope of a line and one of the points on the line is: d. point-slope form.
<h3>What is the
point-slope form?</h3>
The point-slope form can be defined as an equation which is used when the slope of a line and one of the points on this line is known.
Mathematically, the point-slope form of a line is given by:
y - y₁ = m(x - x₁)
<u>Where:</u>
In conclusion, you should use the point-slope form when you know the slope of a line and one of the points on the line is given.

The length of the windshield wiper to the nearest inch is 24 inches
<h3>How to calculate the area of a sector</h3>
The formula for calculating the area of a sector is given as:
A = r²β/2
r is the length of the wiper
β is the subtended angle
Given the following
A = 500.3 square in
β = 98 degrees = 98pi/180 = 49pi/90
Substitute
500.3 = r²49pi/180
500.3 = 153.86r²/180
153.86r² = 90054
r² = 585.298
r = 24.19
Hence the length of the windshield wiper to the nearest inch is 24 inches
