3. An action movie is being filmed at the Perrine Bridge in Twin Falls, Idaho. The hero of the movie, Wynono Homer, leaps off the bridge over the Snake River and then pulls a parachute to slow his fall. To avoid risk, the director will use computer-generated imagery (CGI) for this scene. The animators must create an accurate model of the jump and descent to make the scene look realistic! Before he pulls the parachute, Wynono's path can be modeled by the equation h = -4.9t² +t+ 148. The height above the Snake River is represented by h (meters), and t (seconds) is the amount of time of his jump. The movie director gives the animators the following table, which shows the approximate heights and times the director wants Wynono to pass through after he opens his parachute. Time from initial jump (seconds) 10| 15 20 Height above Snake River (meters) 38.8 25.8 8.8 According to this information, at what height will Wynono open his parachute in the movie scene? Your Task: Work with your team to find as many ways as you can (with and without your graphing calculator) to determine the height above the river at which Wynono opens his parachute. Be sure to analyze tables, graphs, and equations as you work. What is an appropriate domain for each of the functions that describe Wynono's descent?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
