A scalene triangle has the lengths 6, 11, and 12. Keyla uses the law of cosines to find the measure of the largest angle. Complete her work and find the measure of angle Y to the nearest degree. 1. 122 = 112 + 62 − 2(11)(6)cos(Y) 2. 144 = 121 + 36 − (132)cos(Y) 3. 144 = 157 − (132)cos(Y) 4. −13 = −(132)cos(Y)

What is the graph of the function fx x+2/x-3?

Abusiness plan is centered around a circular area of distribution. the plan calls for the radius of the distribution to increase 50 miles per year. the investors have asked that the plan include a reference to the area of distribution based on the number of years in business. these functions model this plan: radius in y years: r(y) = 50y total area: a(r) = πr2; r in miles what is a(r( the total area in y years? a(r(y)) = 50πy2 a(r(y)) = 2,500πy2 a(r(y)) = 50πr2 a(r(y)) = 2,500πr2
