A toroidal solenoid has 600 turns, cross-sectional area 6.20 cm2cm2, and mean radius 4.70 cmcm. Part A Calculate the coil's self-inductance. Express your answer in henries. If the current decreases uniformly from 5.00 AA to 2.00 AA in 3.00 msms, calculate the self-induced emf in the coil. The current is directed from terminal a of the coil to terminal b. Is the direction of the induced emf from a to b or from b to a? From a to b From b to a

B rielemelosmick I0/23724 - Illustrative 1 Mathematics Lesson 22 Practice Problems 1. To qualify for a loan from a bank, the total in someone's checking and savings accounts together must be \( \$ 500 \) or more. a. Which of these inequalities best represents this situation? \[ \begin{array}{l} x+y<500 \\ x+y \leq 500 \\ x+y>500 \\ x+y \geq 500 \end{array} \] b. Complete the graph so that it represents solutions to an inequality representing this situation. (Be clear about whether you want to use a solid or dashed line.)
A national online business magazine reports that the average cost of a speeding ticket in Miami, including court fees, is \( \$ 220 \). A local police department claims that this amount has increased. To test their claim, they collect data from a simple random sample of 16 drivers who have been fined for speeding in the last year. Assuming that the distribution of speeding ticket costs is normally distributed and the population standard deviation is \( \$ 13 \), is there sufficient evidence to support the police department's claim at the 0.02 level of significance? \begin{tabular}{|l|l|l|l|l|l|l|l|} \hline \multicolumn{7}{|c|}{ Speeding Ticket Costs in Miami } \\ \hline\( \$ 200 \) & \( \$ 238 \) & \( \$ 208 \) & \( \$ 213 \) & \( \$ 243 \) & \( \$ 215 \) & \( \$ 246 \) & \( \$ 244 \) \\ \hline\( \$ 227 \) & \( \$ 240 \) & \( \$ 225 \) & \( \$ 226 \) & \( \$ 215 \) & \( \$ 224 \) & \( \$ 240 \) & \( \$ 200 \) \\ \hline \end{tabular} Copy Data Step 2 of 3: Compute the value of the test statistic.

Use Stokes's Theorem to evaluate \( \int_{C} \mathbf{F} \cdot d \mathbf{r} \). In this case, \( C \) is oriented counterclockwise as viewed from above. \[ \mathbf{F}(x, y, z)=y z \mathbf{i}+(2-7 y) \mathbf{j}+\left(x^{2}+y^{2}\right) \mathbf{k}, x^{2}+y^{2} \leq 36 \] S: the first-octant portion of \( x^{2}+z^{2}=36 \) over \( x^{2}+y^{2}=36 \)
