- Measurement Use the fact that 13 inches is approximately the same length as 33 centimeters to find a mathematical model that relates centimeters y to inches x. Then use the model to find the numbers of centimeters in 10 inches and 20 inches.arrow_forwardMeasurement Use the fact that 14 gallons is approximately the same amount as 53 liters to find a mathematical model that relates liters y to gallons x. Then use the model to find the numbers of liters in 5 gallons and 25 gallons.arrow_forwardTEST YOUR UNDERSTANDING In the situation of the example, if the structure is 90feet tall, how long does it take for the rock to hit the ground?arrow_forward
- Using your graphing calculator, make a scatter plot of the data from the table. Then graph your model from Question 2 along with the data. How well does your model fit the data? What could you do to try to improve your model?arrow_forwardRe-do the example under the assumption that the height of the tent 5 feet toward the center from the outside is 13 not 12 feet. The outside wall of the circus tent depicted in Figure 3.9 is 10 feet high. Five feet toward the center pole, the tent is 12 feet high. The center pole of the tent is 60 feet from the outside wall.arrow_forwardCONCEPTS The point that is 2 units to the left of the y-axis and 4 units above the x-axis has coordinates __, __.arrow_forward
