Answer:
11.2 in
Step-by-step explanation:
The product of distances to the near and far intersection points with the circle is the same for any secants intersecting at a given external point. A tangent is the degenerate case where the near and far points of intersection are the same. This means ...
(9)(9) = (5)(5 + y)
81/5 = 5 + y
16.2 -5 = y = 11.2 . . . . inches

Step-by-step explanation:
Mathpapa is a pretty good and reliable algebra calculator would say to use it. It also has Inequalitys and system of equations calculators.
a fraction is a representation of a proportion, like say you have a pizza and cut it in 6 pieces, each piece is 1/6 of the pizza,
.
the total number of available slices in the pizza is 6, you cut it in 6 slices, and a single unit of it or just 1, is 1/6 or one sixth of the pizza.
in short, a rational number is one you can write as a fraction, and an irrational number is one that can't be written as a fraction, a good example of those are π , or e euler's constant or √2.
I think it is a one to one function
Answer:

Step-by-step explanation:
we know that
The <u>Triangle Inequality Theorem</u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
so
Applying the Theorem
case 1) 



case 2) 


-----> rewrite
case 3) 



therefore
