1) Determine a equação da reta que passa por P(3,-5) e pelo baricentro do triângulo de vértices nos pontos A(-1,5), B(5,7) e C(8,3). 2) Sabendo que a distância do ponto P(3,b) à reta 4x – 3y + 2 = 0 é igual a 2. Determine o valor de b²

Abilliard ball is struck by a cue. it travels 1 0 0 cm 100cm before ricocheting off a rail and traveling another 1 2 0 cm 120cm into a corner pocket. the angle between the path as the ball approaches the rail and the path after it strikes the rail is 4 5 ∘ 45 ∘ . how far is the corner pocket from where the cue initially struck the ball? do not round during your calculations. round your final answer to the nearest centimeter.
