1. Use the zero product property to find the solutions to the equation x2 – 13x + 30 = 0.
2 answers:
1) x² - 13x + 30 = 0 x² ⇒ x * x -13x ⇒ -10x - 3x 30 ⇒ -10 * -3 (x-10) (x-3) = 0 x - 10 = 0 ⇒ x = 10 x - 3 = 0 ⇒ x = 3 Answer is Choice D:) x = 3 or x = 10 2. P(x) = 480x - 2x² a) P(100) = 480(100) - 2(100²) = 48,000 - 20,000 = 28,000 b) P(120) = 480(120) - 2(120²) = 57,600 - 28,800 = 28,800 c) P(240) = 480(240) - 2(240²) = 115,200 - 115,200 = 0 THIS IS THE ANSWER.
