AB is tangent to circle O if AO = 30 and bc = 48 what is AB

72

Step-by-step explanation:

30+48=78

√78^2-30^2=

√5184=

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

$12. that is my answer.
