Circle a has center of (2, 3) and a radius of 5. circle b has a center of (1, 4) and a radius of 10. what steps will show that circle a is similar to circle b? a. dilate circle a by a scale factor of 2.
b. translate circle a using the rule (x+1, y−1).
c. rotate circle a 180° about the center.
d. reflect circle a over the y-axis.

Click on the y intercept. -x +4 i know you cant click on it so could you just say the coordinates like (example - (1,0) you so much.

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
