- One of the world’s least-regarded companies, Chegg Inc.1, runs a website that some critics and reviewers lambaste as a “waste of money” run by “con artists.” This company claims that students who pay for their services are more likely to succeed in college courses, but such claims are dubious at best. Shown below is a graph y = f(x) that displays a typical Chegg user’s performance on graded work in a Math course over a four month period. Their running average is displayed along the vertical y-axis with the horizontal x-axis displaying time. a. Naming the labeled points so that P = (p, f(p)), Q = (q, f(q)) and R = (r, f(r)), arrange the numbers f'(p), f'(q) and f'(r) in order from least to greatest: ___ < ___ < ___b. Based on the given graph, what is the students’ actual course grade (approximately)? That is, approximate thevalue of limx→4− f(x) (limit of 4 from the left-hand side).the graph is attached below. thank you so much.Outside temperature over a day can be modeled as a sinusoids function. Suppose you know the high temperature of 100 degrees occurs at 4pm and the average temperature for the day is 85 degrees. Find the temperature, to the nearest degree, at 6Am ?Help me graph the following equation either by hand or using any graphing software. I think it should be a periodic unit step function.
- After an injection, the concentration of a drug in a patient's body increases rapidly to a peak and then slowly decreases. Graph the concentration of the drug in the body as function of the time since the injection was given. Assume that the patient has none of the drug in the body before the injection. Label the peak concentration and the time it takes to reach that concentration. Do this on your paper.Note you can read up on the Surge Function in Section 4.8 page 222 fig 4.83 a. the curve is concave down always b. the curve is concave up always c. the curve is concave up at first & later concave down d. the curve is concave down at first & later concave up e.

Part 1. Graph this function in an appropriate window. Make sure to label axes, scale, and all important features of the graph. (I think that this is going to be agraph that goes from the bottom right to the upper left, correct?) Part 2. Determine W inverse -1 = (28). What does this mean in the given context?
- This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A group of hikers uses a GPS while doing a 40-mile trek in Colorado. A curve fit to the data shows that their altitude can be approximated by the function y(t)=0.12t5−6.75t4+135t3−1120t2+3200t+9100yt=0.12t5-6.75t4+135t3-1120t2+3200t+9100 where y and t are expressed in feet and hours, respectively. During the 18-hour hike, determine the maximum altitude that the hikers reach. (You must provide an answer before moving on to the next part.) The maximum altitude is ft.An airport can be cleared of fog by heating the air. The amount of heat required depends on the air temperature and the wetness of the fog. The figure below shows the heat H(T,w) required (in calories per cubic meter of fog) as a function of the temperature T (in degrees Celsius) and the water content w (in grams per cubic meter of fog). Note that this figure is not a contour diagram, but shows cross-sections of H with w fixed at 0.1, 0.2, 0.3, and 0.4. (a) Estimate HT (10,0.2): HT (10,0.2) ≈ (Be sure you can interpret this partial derivative in practical terms.) (b) Make a table of values for H(T,w) from the figure, and use it to estimate HT (T,w) for each of the following: T = 20,w = 0.2 : HT (T,w) ≈ T = 30,w = 0.2 : HT (T,w) ≈ T = 20,w = 0.3 : HT (T,w) ≈ T = 30,w = 0.3 : HT (T,w) ≈ (c) Repeat (b) to find Hw(T,w) for each of the following: T = 20,w = 0.2 : Hw(T,w) ≈ T = 30,w = 0.2 : Hw(T,w) ≈ T = 20,w = 0.3 : Hw(T,w) ≈ T = 30,w = 0.3 : Hw(T,w) ≈ (Be sure you can interpret this…Shown is a graph of y=f(x) Is this function even,odd, or neither?
