What coordinate expression represents the coordinates of any point after dilation by a scale factor of 2

neonofarm [45]

Answer: (x,y) → (2x,2y) .

Step-by-step explanation:

A dilation is a transformation that changes the size of the image. It either shrink or enlarge a shape by using a scale factor about a center of dilation.

If we transform point (x,y) by using dilation with scale factor k (assume center of dilation at (0,0) then the coordinate of the image will be (kx,ky).

So, the coordinate expression represents the coordinates of any point after dilation by a scale factor of 2:

(x,y) → (2x,2y) .

there are 76 birdhouses, if 4 birdhouses are occupied, how much percent of the birdhouses are occupied?

Llana [10]

To find the percent of the birdhouses occupied, divide the number of occupied birdhouses by how many birdhouses there are in total:

$4 \div 76 = 0.0526$

Convert this decimal into a percentage by multiplying by 100:

$0.0526 \times 100 = 5.26$

5.26% of the birdhouses are occupied.
