Angle
A is circumscribed about circle O. What is the length of AB

4

Step-by-step explanation:

In your imagination draw a line through A and O.  Reflect triangle ACO about this line.  Then AB is of the same length as AC:  4.

Similarly, the radii OC and OB have the same length, and so OB = 3.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
