Write an equation for the parabola shown to the right. a (4.0 ( 3-1) The equation of the parabola is (Use integers or fractions for any numbers in the equation)

Answer 1

Solution: .y (4,0) xx List yl The standard equation of the parabola. (4-K) = 49(x-h) Chok) = (3,-1) (4-(-0= 4a)(x-3 (4+1) = 4a (8-3) and passing through point (4,0). (0+11? = y0 (4-3) . ya al ک۔ Therefore, Equation of parabola is ( 4 + 5^= 4 ; z-3) 키 (y+12=(x-3)

solution: Given that : Bridge Span s=120 ft maximum height h = = 35 feet S (0,39) 60,0) (60,0) Equation : he? = 40 (4- B5) of parabola And passing through point, (60,0) 60% = 4a (0-35) ya 602 a = x² -19 Therefore, =4 (139) (4-35) 7 x ² =-720 (4-35) o For x=10 ft 76103²=720 (9-35) height (y) = 34.027 ft ha 26.25 ft in For a=soft ; h= 10.69 ft $ ) For se= 30ft ;
