Assume that x and y are functions of t, and x and y are related by the equation y= 4x+3. (a) Given that dx/dt=1, find dy/dt when x=2. (b) Given that dy/dt=4, find dx/dt when x=3.
Country A and country B are two neighboring countries. The inverse supply and demand functions for electricity (TWh) in these two countries are given by: Sa = 7,5+0.15Xa Da = 21 -0.075Xa Sb = 15+0.15Xb Db = 24 -0.0375Xb where Sa, is supply price in country A, Da is demand price in country A and Xa, is the corresponding volume in country A. Similar notation for country B. These functions are only valid in the ranges where both prices and...
A circle has an initial radius of 50 ft when the radius begins decreasing at the rate of 2 ft/min. What is the rate in the change of area at the instant that the radius is 23 ft? Write an equation relating the area of a circle, A, and the radius of the circle, r. (Type an exact answer, using a as needed.) Differentiate both sides of the equation with respect to t. dA dr dt dt (Type an exact...

Explain how to get that Bower law function. When illustrating two quantities that are related through a power law function, it is common to use a log vs log plot. It is therefore important to be comfortable with both of these forms. A log vs log plot is shown in Figure 2. From the equation of the trendline, which of the equations below best represents the relationship between the quantity y and the quantity x (Figure 2) Figure y-0.58.3 2...
3. A positive charge is contained inside spherical shells as shown below. dB /dB Consider two small surface elements on the shell surface dA and 68, located on opposite side of the shell 3a. How does the electric flux through the two surface elements, dOA and dog change when the charge is moved from position 1 to position 2? A. DOA increases and dog decreases B. DOA decreases and dog increases C. Both dOA and dog do not change 3b....
