Dilate the given points distance from the origin (x,y) (0.8x, 0.8y) . The point (-10,-20) becomes & point (15,25) become
dalvyx [7]

Answer: The point (-10,-20) becomes (-8,-16) & point (15,25) becomes (12,20).

Step-by-step explanation:

When a point (x,y) is dilated by a scale factor k from the origin, then the new points become

(kx,ky).

The given rule of dilation : (x,y) →(0.8x, 0.8y)

The first point is (-10,-20), so its image will be

(-10,-20)\to (0.8\times-10,0.8\times-20)=(-8,-16)

So, the point (-10,-20)  becomes (-8,-16).

The second point is (15,25), so its image will be

(15,25)\to (0.8\times15,0.8\times25)=(12,20)

So, the point (15,25) becomes (12,20).

Hence, the point (-10,-20) becomes (-8,-16) & point (15,25) becomes (12,20).

A circle has an area of 497 square inches. What is the circumference of the circle?
Aleksandr-060686 [28]

Answer:

easy peasy

Step-by-step explanation:

we have, area = 497 sq. units

that is, (pi) (radius)^2=497

=> (22/7) x r^2 = 497

=> r^2 = 158.13

=> r = √158.13

=> r = 12.57

now we also have radius, soooo

=> circumference = 2 (pi) (radius)

=> (2) (22/7) (12.57)

=> 79.01 inches
