2. Graph the model of the roller coaster using the graphing calculator. Take a screenshot of your graph and paste the image below, or sketch a graph by hand. (5 points)
Model 1: One plan to secure the roller coaster is to use a chain fastened to two beams equidistant from the axis of symmetry
of the roller coaster, as shown in the graph below:

Okay so that is the graph I need to draw but just the orange half part of the circle but I can’t seem to find the equation to put in Desmos and draw it because every equation I try doesn’t work so if you could help that would be greatly appreciated!:)

1. how do you convert the repeating, nonterminating decimal 0. to a fraction? explain the process as you solve the problem.

What is the point slope form of a line with slope -5 that contains point (2,-1)

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i.e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
