Question

Question 22 (multiple choice) A football field inside a stadium has a parabolic shape to help rain drain from the field. The approximate height of the field is modeled by the quadratic equation (-2.34 x 10-4) (d-80) +1.5 4.5 3.5 h (-2.34 x 104 (d 80) 1.5 2.5 ?? 1.5 0.5 A0 20 40 60 80 100 120 140 160 d distance across the field (feet) 2016 FlipSwitch. Created using GeoGebra Consider the statement: When the height of the field is 1.29 feet, the distance across the field is approximately 59.33 feet or 100.67 feet. Which option describes the validity of this statement? The statement is incorrect. The standard form should be set equal to 1.29 and solved for d :-0.000234d2 + 160d + 6400-1.29. Then, the distance equals 33.77 or 126.23 feet. The statement is correct. The standard form should be set equal to 1.29 and solved ford:-0.000234d2 + 0.03744d + 0.0024 = 1.29. Then, the distance equals 59.33 or 100.67 feet. The statement is incorrect. The standard form should be set equal to 1.29 and solved for d :-0.000234d2 + 0.03744d + 0.0024-1.29. Then, the distance equals 50.04 or 109.96 feet. The statement is correct. The standard form should be set equal to 1.29 and solved for d :-0.000234d2 + 160d + 6400-1.29. Then, the distance equals 59.33 or 100.67 feet.
