Circle a has center of (2, 8) and a radius of 2. circle b has a center of (5, 4) and a radius of 10. what steps will show that circle a is similar to circle b?

translate circle a using the rule (x−3, y+4).

rotate circle a 270° about the center.

reflect circle a over the line x=1

dilate circle a by a scale factor of 5.

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x
