Kristen stands 6m from a painting, admiring its beauty. She walks 5m towards it at aconstant rate for 4 s. She stops at this location for 3 s, the she walks away for 4m at aconstant rate for 8s. a) Draw a distance versus time graph to show Kristen’s distance from the painting.b) What is the instantaneous rate of change at 2 seconds?c) What is her average rate of change between t =0 and t =15? Explain why this does notaccurately represent Kristen’s movement between t =0 and t =15.

Incorrect: Your answer is incorrect. sec (b) What was the average velocity of the screwdriver between the time it was dropped and the time it hit the ground? ft/sec (c) What was the velocity of the screwdriver at the time it hit the ground? ft/sec
I don't understand step 4, why it was necessary to find when velocity is 0 and why velocity is 0 at t=20.

You have been hired by a firm that is designing a runway for an airport. Your job is to confirm that the runway is long enough for an airplane to land, but notunnecessarily long. You are given the velocity data for the largest aircraft that will land at the airport. The velocity data will be used to calculate the distancerequired for the aircraft to safely land and come to a stop.Below is a set of data that represents the velocity (in feet per second) of the final 45 seconds of the landing. At t = 0, the plane is on its final descent.Table It in seconds 0 | 5 | 10 |15 | 20 | 25 | 30 v(t) in feet per second 274.27| 223.19 |179.23| 141.4|108.83| 80.80| 56.68 35 | 40 | 45 35.91| 18.04 | 2.65 Calculate the average change in the rate of change using table above From t=0 to t=45 From t=25 to t=45 From t=40 to t=45

The following question are for the attachment. Thank you!! 1) Explain why the first attempt did not make sense to Ken. 2)Explain why the second attempt does not work out to be the correct rate of change either. 3) Determine the correct rate of change. 4) Explain what the rate of change means in terms of the skydiver’s decent.
Suppose that you drive from College Station to Houston (say 100 miles) and it takes you 90 minutes to get there. Now suppose that your on-board computer calculates your average velocity as follows: it samples your current velocity every second, and it calculates the average of all the velocities measured over the span of the trip. What is your best guess for what answer your computer calculates for the average velocity?
The 2011 Tōhoku, Japan earthquake is the newest deadliest earthquake. The power was equal as about 600.000.000 Hiroshima bomb. After the 9.0 magnitude earthquake, 900 aftershocks emerged and around 13,705 casualties had to lose their lives during the course. Because the earthquake so powerful, it has shifted our earth axis by 25 cm. 5. Based on this information, arrive to the conclusion on how much stronger was this earthquake in comparison with 2017 Mexico earthquake. Show work.
The oxygen consumption of a turkey embryo increases from the time the egg is laid through the time the chick hatches. In a brush turkey, the oxygen consumption can be approximated by c(t) = −0.028t3 + 2.9t2 − 44t + 95 milliliters per day (20 ≤ t ≤ 50), where t is the time (in days) since the egg was laid.† (An egg will typically hatch at around t = 50.) Use technology to estimate the total amount of oxygen consumed during the 23rd and 24th days (t = 22 to t = 24). Round your answer to the nearest 10 milliliters.
