What is the length of st? give how you solved this .

If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment (Intersecting Secant-Tangent Theorem)

so

ST²=RO*RT> ST²=23*7> ST²=161

ST=√161> ST=12.69 in

the answer is

ST=12.69 in

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
