The percent of a country's households with broadband Internet access can be modeled by the function f left parenthesis x right 0.11 x squared plus 6.51 x plus 3, where f left parenthesis x right parenthesis is the projected percent of households with broadband Internet access and x is the number of years since 2000. a. Will this function have a maximum or a minimum? How can you tell?
b. According to this model, in what year will the percent of homes with broadband Internet access be at its maximum or minimum?
c. What is the predicted maximum/minimum percent of homes with broadband Internet access?

Intersecting secant-tangent theorem states 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.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
