// // // // // The tangent line to a circle may be defined as the line that intersects in a single point, called the point of tangency. See the figure.

If the equation of the circle is x2+y2 = r2 and the equation of the tangent line is y = mx+b, SHOW THAT:

a) r2 (1+m2) = b2 [The quadratic equation x2 + (mx + b)2 = r2 has exactly one solution.

b) The point of tangency is (-r2m/b , r2/b)

c) The tangent line is perpendicular to the line containing the center of the circle and the point of tangency

Question:Looking below is this answer correct? If you follow the math, you reach the entire population before 8 hours have passed yet the solution says 8.86 hours....Is the solution giving us the numbers in the set and not the actual elapsed hours???Does anyone know why?
the population of humorville is 8,500 people. in this town, jokes travel fast. in one hour, each person who hears a joke tells three other people who have not heard it, and tells no one else. last frieday, a visitor from out of town told the police chief a new joke at 10:00 a.m. how long did it take for everyone in humorville to hear the joke? math - Reiny, Sunday, February 24, 2008 at 9:34pm
at 10:00 one person heard it
at 11:00 1 + 3 heard it
at 12:00 1 + 3 + 9 hear it
..
.
looks like a geometric series with
a=1
r = 3, and Sn = 8500 1(3^n - 1)/(3-1) = 8500
3^n - 1 = 17000
3^n = 17001
n = log 17001/lg3
n = 8.86 hours or appr 9 hours so at 19:00 hrs, or in the US way of stating time, at 7:00 pm
