After heating up in a teapot, a cup of hot water is poured at a temperature of 207∘F. The cup sits to cool in a room at a temperature of 68∘F. Newton's Law of Cooling explains that the temperature of the cup of water will decrease proportionally to the difference between the temperature of the water and the temperature of the room.
The cup of water reaches the temperature of 186∘F after 2.5 minutes. Using this information, find the value of kk, to the nearest thousandth. Use the resulting equation to determine the Fahrenheit temperature of the cup of water, to the nearest degree, after 5.5 minutes.
Enter only the final temperature into the input box.
Prices of diamonds are determined by what is known as the 4 Cs: cut, clarity, color, and carat weight. The prices of diamonds go up as the carat weight increases, but the increase is not smooth. For example, the difference between the size of a 0.99-carat diamond and a 1-carat diamond is undetectable to the naked human eye, but the price of a 1-carat diamond tends to be much higher than the price of a 0.99 diamond. In this question, we use two random samples of diamonds, 0.99 carats and 1 carat, each sample of size 23, and compare the average prices of the diamonds. In order to be able to compare equivalent units, we first divide the price for each diamond by 100 times its weight in carats. That is, for a 0.99-carat diamond, we divide the price by 99. For a 1 carat diamond, we divide the price by 100. The distributions and some sample statistics are shown below

Astronomers can approximate the distance to a galaxy by measuring its red shift, which is a shift in the wavelength of light due to the velocity of the galaxy. This is similar to the way the sound of a siren coming toward you seems to have a higher pitch than the sound of the siren moving away from you. A formula for red shift is
red shift =
?r − ?s
?s
,
where
?r
and
?s
are wavelengths of a certain frequency of light. Calculate the red shift for a galaxy for which
?r = 4.16 × 10−6
meter and
?s = 4.02 × 10−6
meter. (Enter your answer in scientific notation and round the decimal value to two decimal places.)

- The airspeed of a plane is its speed in the absence of wind. With a headwind, ground speed (the actual speed in relation to the ground) is decreased by the speed of the wind. With a tailwind, ground speed is increased by the speed of the wind. Let A denote the airspeed of a plane and W the speed of the wind, both in miles per hour. Suppose it takes the plane 6 hours to travel the 720 miles from one town to another facing a headwind of W. The return trip, now with a tailwind of W, takes only 3 hours. (a) Express the ground speed on the trip out in terms of A and W. (b) Use the information from part (a) and the fact that distance equals rate times time to find an equation involving A and W for the trip out.
