Use the fact that the resistance of a wire carrying an electrical current is directly proportional to its length and inversely proportional to its cross-sectional area. ​ A 13-foot piece of copper wire produces a resistance of 0.2 ohm. Use the constant of proportionality k = 0.000833 to find the diameter of the wire. ​ (Round the answer to three decimal places.) ​

Use Descartes’ Rule of Signs to determine the possible number of positive and negative zeros of .

While performing a square wave test on an arterial line monitoring system at the start of your shift, you notice that the waveform indicates the system is under damped. How will this affect the pressure readings on the monitor?

Determine whether the line through the given points and the line through R(8,7) and S(5,14) are parallel, perpendicular, or neither. ​ Choose the correct letter for each question.

Select from the following which is the polynomial function that has the given zeros. ​

Solve the inequality. ​ 18.2 – 1.3x < -5.2 ​

Choose the correct statement regarding Clark electrodes and Galvanic cells.

Assume that y is directly proportional to x. If x = 28 and y = 21, determine a linear model that relates y and x.

All of the following are reasons for finding an alternative site for arterial puncture except:

The simple interest on an investment is directly proportional to the amount of the investment. By investing $6500 in a certain certificate of deposit, you obtained an interest payment of $130.00 after 1 year. Determine a mathematical model that gives the interest, I, for this CD after 1 year in terms of the amount invested, P.
