1. The equation y=x^2-9x+20 models the roller coasters path over time. The variable y represents height (in feet) above or below the platform. At y=0, the roller coaster is even with the platform. The variable x represent the amount of time (in seconds) since the ride began.Part 1: write the equation in factored form.Part 2: find the vertex of the parabola. Hint: to find the x-value of the vertex, take the average of the x-values of the x-intercepts of use the first part of the quadratic Formula (x=-b) —— 2aPart 3: what is the y-intercept? Use the equation y=x^2-9x+20Part 4: Sketch the graph of y=x^2-9x+20. Identify the vertex and x- and y-intercepts on your sketch Part5: use the graph to answer the questions.A. Between what times does the roller coaster dip below the platform?B. What is the height and time at which Erin picture is taken during the roller coaster ride?C. Erin picture is taken at the lowest point of the roller coaster.35points!! To whoever help me with this.

A family is visiting 5 states within 10 days for vacation. There are 4 people in the family. They have the option to travel 304 miles on the first day and visit 1 national park and 2 lakes. Or they can travel 260 miles to see a water park and an amusement park that each cost all ages $5. The national park costs $25 per vehicle and the 2 lakes are free. The next 3 days, they travel 284 miles and relaxed by the pool. The family vehicle can go 300 miles on a tank of gas worth $40. The last 4 days, they spend driving the same route back home and stopping at popular sightseeing landmarks.On the first day, how much does the cheaper route cost? Round your answer to the nearest cent and do not include $ in the answer. For example, if the cost is $19.01, put 19.01.
