Answer:
r = 1/6
Step-by-step explanation:

Multiply both sides by 4

Divide both sides by 3

With respect to the parent function,
y = 1/(x+5) +2
is translated 5 units left and 2 units up.
Using the equations for tangent and secant lines:
Let the unknown length of the line inside the circle = y
6^2 = 3 x (y+3)
Simplify:
36 = 3y+9
Subtract 9 from both sides:
27 =3y
Divide both sides by 3:
Y = 9
Now add to get x:
X = 9 + 3 = 12
X = 12
The probability to be inside the large square is 3/10 and the probability to be inside the small square is 7/10
