First, we have to find the difference between the x and y numbers in the table. By dividing the y by the x, the c is being multiplied by 15.
So the answer would be y=15x

The radius, r, of the circle is the distance from the center to any point on the circle.
r = √[(1-(-3))2+(5-2)2] = √25 = 5
An equation of the circle with center (h,k) and radius r is:
(x-h)2 + (y-k)2 = r2
So, in this problem, we have (x+3)2+(y-2)2=25.
To find a point on the circle with x-coordinate -7, replace x by -7 in the equation of the circle and solve for y:
(-7+3)2+(y-2)2 = 25
16 + (y-2)2=25
(y-2)2 = 9
y-2 = 3 or -3
So, y = 5 or -1
The points (-7,5) and (-7,-1) both lie on the circle.
The line passes through points (0,3) and (-1,0)
So the slope is (0-3)/(-1-0) = -3/-1 = 3
so we get y = 3x + c
Replace (3,0) in the equation to find c.
0 = 3(3) + c
c = -9
So the equation of the line is y = 3x - 9
Answer:
Step-by-step explanation:
Given
Circumference = 28 meters
2
= 28
2 * 3.14 * r = 28
r = 28 /6.28
Therefore r = 4.5 meter
The theoretical tail-head probability in flipping an unbiased coin is equal to 50%-50%. Given that 2 heads out of the 3 coin flips, only 1 flips towards tail. This is 1/3 or 33% of the events. Thus, the answer to the question above is letter C.
