7. The coordinates of the vertices of a rectangle are goI byR(-3,-4), E(3, 4), C(4,4), and T(4-4). Plot these pointson the coordinate plane at the right and connect them todraw the rectangle. Then connect points E and T to formdiagonal ET.a. Use the Pythagorean Theorem to find the exactlength of ET.b. How can you use the Distance Formula to find thelength of ET? Show that the Distance Formula givesthe same answer

You can determine the approximate temperature in degrees Fahrenheit by counting the number of times a cricket chirps in one minute. Then multiply that by 7, divide by 30, and add 40. a. Write a formula for estimating the temperature based on the number of cricket chirps. b. Write a new formula for the number of chirps you would expect in one minute at a given Fahrenheit temperature. c. Use the formula to find the number of chirps in one minute when the temperature is 89°F.

In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, with a maximum speed of 183.58 mi/h. The one-way course was 5.00 mi long. Acceleration rates are often described by the time it takes to reach 60.0 mi/h from rest. If this time was 4.00 s, and Burt accelerated at this rate until he reached his maximum speed, how long did it take Burt to complete the course ?
