Question 1162859: Imagine you are set designer for Universal Studios movie company. You plan movie sets using freehand sketches and your computer. In one scene, a banner will hang across a parabolic archway. To make it look interesting, you have decided to put the banner at an angle along a line defined by the linear equation y = 0.6x+ 3.8, with x representing the horizontal distance and y the vertical distance in metres, from the foot of the archway. The archway is modelled by the quadratic equation y = - 0.27x^2+ 3.04x.
a) How can you use the equations to determine the points where the banner needs to be attached to the archway? You can use Technology or the grid below to help with your explanation.
b) What would be the length of the banner?

Question 1163246: Please help me with this question please.
*A Civil Engineer is designing paving around a rectangular pool measuring, L x W (in metres). The paving is to be the same width, x (in metres), around all sides of the pool (still forming a rectangle). Use the quadratic formula to algebraically determine the width of the walkway based on having A m^2 of paving.
Hint: Do not substitute values and then attempt to solve. The values of the variables are not known. Also please include a diagram.
Thank you

Question 1163641: In 1995, the sports league introduced a salary cap that limits the amount of money spent on players' salaries. The quadratic model y=0.2313x2+2.600x+35.17 approximates this cap in millions of dollars for the years 1995-2006, where x=0 represents 1995, x=1 represents 1996, and so on. Complete parts a and b.
a) Approximate the sports league salary cap in .
b) According to the model, in what year did the salary cap reach 65 million dollars?
