Prove that's the decimal number 9.86 is a rational by finding its fractional form
Korvikt [17]
9.86 = 9.86/1 = (9.86 x 100) / (1 x 100) = 986/100, GCF of 986 and 100 is 2, (986/2) / (100/2) = 493/50  The fractional form of 9.86 is 943/50.

Rectangle PQRS is dilated by a scale factor of 2 (k=2) with the origin as the center. What are the coordinates of R('?
Radda [10]

Answer:

Correct Answer: (8,2)

Step-by-step explanation:

<u>Dilation about the origin</u>

Most dilations in the coordinate plane use the origin, (0,0), as the center of the dilation.

In such cases, every point (x,y) dilated by a factor of k is mapped to the point (kx,ky).

The point R=(4,1) is dilated by a scale factor of 2 (k=2), thus the coordinates of its image are (2*4,2*1) = (8,2)
