What size transformation will transform a circle with center at the origin and radius of 4 onto a circle with the same size center and radius 3?

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
