1. Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Then find the area of the region. y = 6 + \sqrt{x}, y = 6 + (1/4) x
2. Sketch the region enclosed by x = 5 y^2 and x + y = 4. Decide whether to integrate with respect to x or y. Then find the area of the region.
3. Sketch the region enclosed by x + y^2 = 42 and x = y. Decide whether to integrate with respect to x or y. Then find the area of the region.
4. Find the area of the region enclosed between y = 3 sin(x) and y = 4 cos(x) from x=0 to x=0.7*pi. Hint: Notice that this region consists of two parts.
5. Find c > 0 such that the area of the region enclosed by the parabolas y = x^2 - c^2 and y = c^2 -x^2 is 30. c= 6. Find the area of the region bounded by the parabola y = 4 x^2, the tangent line to this parabola at (3, 36) and the x axis.
A 150MW alternator generates an open-circut line-t0-line voltage of 12kV at nomial DC excitiation. When the terminals are placed in short-circuit the resulting current per phase is 8000A. a) Calculate the approximate value of the synchronous reacta..
What is the maximum symbol rate for this link and the number of bits per symbol? What format would you recommend for the transmitted current pulses on this baseband link?
The rotor of a 3phase, 5kw, 400v, 50Hz, slip ring indution motor is wound for 6 poles while its stator is wound for 4 poles. The approx average no load steady state speed when this motor is connected to 400v, 50Hz what is the supply
Consider a communications channel with a passband of 3 kHz to 27.4 kHz. A modem will be connected to this communications channel and the modem will operate with a signaling rate that is 0.56 the maximum allowable signaling rate for this communicat..
A microwave system requires a +4-dBm audio level to provide 100% modulation. Determine the voltage level required if this is a 600 ohm audio system.
