Both circle a and circle b have a central angle measuring 140°. the ratio of the radius of circle a to the radius of circle
the length of the intercepted arc for circle a is
, what is the length of the intercepted arc for circle b?

step-by-step explanation:

i dont understand

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

y/x of point b= y/x of point a
