Answer:

When finding the area of a sector, you are actually finding a fractional part of the area of the entire circle. The fraction is determined by the ratio of the central angle of the sector to the "entire central angle" of 360 degrees.   [fractional part = ; where n = central angle]

The necessary formulas to get the area of a circle’s segment are the area of the circle’s sector and the triangle it is bounded by. 

Hence the formula for the segment’s area is:Area of Segment = Area of sector – area of the triangle.

The formula of the area of a circle’s sector is:Area of Sector = \frac{central-angle}{2} x (radius of circle)²

While the formula for the area of a triangle is:Area of Triangle = \frac{1}{2} x base of triangle x height of triangle

Which equation represents the line that passes through points (1, -5) and (3,-17)
zvonat [6]

Answer:

A) y=-6x+1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-17-(-5))/(3-1)

m=(-17+5)/2

m=-12/2

m=-6

y-y1=m(x-x1)

y-(-5)=-6(x-1)

y+5=-6(x-1)

y=-6x+6-5

y=-6x+1
