You're on a roll — here's the solution for Item 1: a) Write the inverse of each of the critical points and . Step 1: Find the critical points and by solving the given quadratic equation. The project's progress is modeled by the equation: x^2 - 10x + 16 = 0 We can factor this quadratic equation: (x - 2)(x - 8) = 0 The roots are x = 2 and x = 8. Let = 2 and = 8. Step 2: Write the inverse of each critical point. The inverse of is (1)/(). (1)/() = (1)/(2) The inverse of is (1)/(). (1)/() = (1)/(8) The inverses of the critical points are (1)/(2) and (1)/(8). b) Help Eli come up with an equation that models these inverse critical points. Step 1: Identify the new roots. The new critical points (inverse critical points) are (1)/(2) and (1)/(8). Step 2: Calculate the sum of the new roots. Sum = (1)/(2) + (1)/(8) = (4)/(8) + (1)/(8) = (5)/(8) Step 3: Calculate the product of the new roots. Product = (1)/(2) × (1)/(8) = (1)/(16) Step 4: Form the new quadratic equation. A quadratic equation with roots r_1 and r_2 can be written as y^2 - (sum of roots)y + (product of roots) = 0. y^2 - ((5)/(8))y + ((1)/(16)) = 0 To eliminate fractions, multiply the entire equation by the least common multiple of the denominators (16): 16 (y^2 - (5)/(8)y + (1)/(16)) = 16 × 0 16y^2 - 10y + 1 = 0 The equation that models these inverse critical points is 16y^2 - 10y + 1 = 0.
