Start with a data point provided in the table in step 1 from September 26 and Storm Tracker Portfolio Worksheet make this date t = 0. Note the position's longitude and latitude and record them in Table 1. PRECALCULUS: PARAMETRIC FUNCTIONS Since latitude measures north/south and longitude measures east/west, the latitude coordinate will be y and the longitude coordinate will be x. Now progress through the days along the path. Directions: Meteorologists use sophisticated models to predict the occurrence, duration, and Choose and record one point from each day of the storm. Mark each point t = 1, t = 2, etc. trajectory of weather events. They build their models based on observations that they have Track the storm for a total of 5 days so that you have 5 points in the table, one from each day of made in the past. By understanding how previous weather events evolved, meteorologists can the storm. apply that knowledge to future weather events. For example: Parametric equations can be used to graph the path of an object in space. For example, they can Pick one of the data points for September 26 be used to describe the path of a storm moving through an area. In this portfolio, you will use This point ist = 0 historical storm data to trace the path of a hurricane. From this data, you will use parametric Record the x (longitude) and y (latitude) coordinates in Table 1 equations to model the path of the storm. Pick one of the data points for September 27. This point is t=1 Step 1: Analyze Hurricane IAN of 2022 Record the x (longitude) and y (latitude) coordinates in Table 1 The table below shows the latitude and longitude of Hurricane IAN at different times on each day Repeat for September 27 28, 29 and 30 which will be t=2, 3, 4, 5 from September 26th to September 30"h 2022.

Remember t is just a parametric variable. You are creating two and y at each time point. functions x(t) and y(t) ***If you use a linear regression for this portfolio the highest grade you are able.to earn is a 70*2* Using your equations you found in step 3 to find the predicted x and y coordinates. Plug in the a. Plot x (longitude is the vertical axis) versus t (horizontal axis) (1 point) values t - 0, 1, 2, 3, and 4 into your parametric equations and enter your values for x and y in the table below. b. Plot y (latitude is the vertical axis) versus t horizontal axis. These should be two separate graphs. Make sure to submit the 2 graphs for your instructor to view. Label Table 2 Predicted x & y from your model's equation (2 points) your axes and chose appropriate scales and ranges for your axis. Include a title for each graph.

(1 points) 0 What type of function will you be using for x (longitude versus t) What type of function will you be using for y (latitude versus !) 3 Use your calculator to create a formula for the model you have chosen. Enter the ordered pairs into lists and have the calculator create the best fit function for your model. For example, if your 4 path appears to be exponential, you will have a model of the form y = ab using the ExpReg feature on the calculator. If you think the function is quadratic your model will have the form y = at? + bt + c using the QuadReq feature on the calculator. You will then do the same for x. You do not have to use the same model type for both x and y. Pick the model that fits each one best! a. Plot your predicted x (table 2) and your actual x (table 1) versus time on one graph.

Write your final equations: (2 points) label your axes and chose appropriate scales and ranges. Have a key indicating which data are predicted and which are actual. For example use one color for predicted and one color for x(t) = actual. v (t) = C. Visually compare the actual and predicted data on the plots? Do they seem to be similar?
