1. In an alternating-current circuit...

1. In an alternating-current circuit, the voltage E is given by E=IZ, where I is the current (in A) and Z is the impedance (in Omega) If I=0.859-0.318j amperes and Z=210+150j ohms, find the complex number representation for E. E= volts

2.The electric power P (in W) supplied to an element in a circuit is the product of the voltagee and the current i (in A). Find the expression for the power supplied if e=8.29(angle sign) 90.1(degrees) volts and i=0.0665(angle sign) -31.9(degrees) amperes. P=

3.For a certain model of truck, its resale value V(in dollars) as a function of its mileage m is V=52,000-0.4m. Plot V as a function of m for m</= 100,000 mi. **This asks to graph**

4. Use a calculator to find the irrational root (to the nearest 0.01) that lies between the given values. r^4-3r^3-r^2-r-5=0 (3 and 4) *The root that lies between 3 and 4*

5. If tan(theta)=5/12, what is the value of sin^2theta+cos^2theta?

6. Determine the quadrant in which the terminal side of theta(angle) lies, subject to the given conditions. sec(theta)0
