Price of Gold. The price of gold (end-of-year closing price in dollars per troy ounce) is shown in the table below. Year 1986 1996 2006 2016 Price $391 $369 $636 $1152 The prices shown in the table are not adjusted for inflation. Revise the above table to express all prices in terms of 2016 dollars. If you bought 3 ounces of gold in 1986 and sold it in 1996, would you have seen a profit (adjusted for inflation)? Explain. If you bought 3 ounces of gold in 2006 and sold it in 2016, would you have seen a profit (adjusted for inflation)? Explain.
A Falling Ball In a physics experiment a lead ball is dropped from a height of 5 m. The students record the distance the ball has fallen every one-tenth of a second. (This can be done by using a camera and a strobe light.) Their data are shown in the margin. (a) Make a scatter plot of the data. (b) Use a calculator to find a power model.

Question content area Part 1 At low altitudes, the altitude of a skydiver and time in the air are linearly related. A skydiver jumps out of a low-flying plane. If the plane is 2000 feet above the ground and the jump lasts 85 seconds, how high above the ground was the skydiver 50 seconds after he jumped? He would be enter your response here feet above the ground. (Round answer to nearest tenth of a foot.)
Consider an astronaut on a large planet in another galaxy. To learn more about the composition of this planet, the astronaut drops an electronic sensor into a deep trench. The sensor transmits its vertical position every second in relation to the astronaut's position. The summary of the falling sensor data is displayed in the following table. Time after Position (m) dropping (s) 1. -1 -2 3 -4 4 -8 5 -14 (a) Using a calculator or computer program, find the best-fit quadratic curve to measure the position of the sensor (in m) as a function of t, the time (in s) after the sensor is dropped.

When we chart the price of milk in 1995 dollars we find that it has become slightly more expensive ,but when we chart it in 1975 dollars we find that it has become cheaper. Which statement is correct ?? a. Not make sense, because prices always rise with time b. Not make sense, because the same trend would be seen regardless of what kind of dollars are used c.make sense, because 1975 dollars are worth than 1995 dollars d.make sense,because 1995 dollars more worth than 1975 dollars

Extra Problem A student is speeding down Highway 16 in her fancy red Porsche when her radar system warns her of an obstacle 400 feet ahead. She immediately applies the brakes, starts to slow down, and spots a skunk in the road directly ahead of her. The "black box" in the Porsche records the car's speed every two seconds, producing the following table. The speed decreases throughout the 10 seconds it takes to stop, although not necessarily at a uniform rate. Time since brakes applied (sec) 0 2 4 6 8 10 Speed (ft/sec) 105 85 55 20 15 0 A. What is your best estimate of the total distance the student's car traveled before coming to rest (note that the best estimate is probably not the over or under estimate that you can most easily find, use the trapezoidal approximation)? distance = B. Given the fact that the Porsche slows down during breaking, give a sharp i. underestimate of the distance traveled: ii. overestimate of the distance traveled: C.
