Step-by-step explanation:no need
We know that
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=RT*QT
RT=7 in
QT=23+7-----> 30 in
ST²=7*30-----> 210
ST=√210-----> 14.49 in
the answer is
RT=14.49 in
a test to see if it is a function is a vertical line test, if you draw a straight line and the line intersects at 2 points, it is not a function.
in this case, (-2,-2) is an open hole, which means the value where it is placed is just around that value so not exact.
the vertical line test would work if it was a closed hole, and one or both points (-2,3) and (-2,-2) would have to be removed.
the mistake that deshawn made was that he mixed up the vertical line test with horizontal instead and has deduced that since a horizontal line has intercepted both points, they must be removed.
this graph is, in fact, a function since the open hole is not exactly under (-2,3)
I think the answer to ur question is -3/5
5 + (46 + 7) x 2
5 + (53) x 2
5 + 106
111 is answer
PEMDAS (parenthesis, exponent, multiply & divide, add & subtract)
hope this helps
