Pleas help. Will give extra points.
Brainliest to the one that explains well.

Find the equation of the circle with center (0,-6) and tangent to the x-axis.

X^2+(y+6)^2=36 you get this because you know the radius is six because it’s tangent to the x axis so six squares is 36 and you have the h and I given to you in the center

The answer for you question is b

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
