suppose A=(1,2,3,4,5,6,7),B=(2,4,6.8) and C(7,8,9,10) which of the following statements is or are true BuC=(2,4,6,7,8,9,10).AuC=(7,8).AnBn C=(1,2,3,4,5,6,7,8,9,10).AnBnC=(6,7 ,8)​

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
