To find the scale factor of the dilation, divide the new point's x and y values by the original point's x and y values:
The scale factor of the dilation is
0.75.
For the questions 53-62 all you have to do is use the equation:
y - y1 = m (x - x1)
Then substitute the values and simplify
220 * 5 = 220 * 2/2 * 5 * 2/2 = 440 * 10 / 4 = 110 * 10 = 1100
<em>Equation of a Sphere. The general equation of a sphere is: (x - a)² + (y - b)² + (z - c)² = r², where (a, b, c) represents the center of the sphere, r represents the radius, and x, y, and z are the coordinates of the points on the surface of the sphere.</em>
