Circle y has a center at (2,3) and a radius of 4. circle z has a center at (2,−3) and a radius of 10. what is the scale factor of all radii of circle y to all radii of circle z?

The scale factor of all radii of circle Y to all radii of circle Z is 2.5

Step-by-step explanation:

we know that

The radius of circle Y is 4 units

The radius of circle Z is 10 units

To find the scale factor of all radii of circle Y to all radii of circle Z, divide the radius of circle Z by the radius of circle Y

10/4=2.5

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

.25
