Oriole Company is considering replacing equipment with a cost of $33000, accumulated depreciation of $22000, and a 2-year remaining useful life. The new equipment has a cost of $46200 and a useful life of 6 years. The seller has offered a trade-in allowance of $8250. The new equipment is much more efficient. Oriole projects cost savings of $110000 per year if the new equipment is purchased. Which of the following is not relevant in deciding whether to retain or replace equipment? Cost savings. Cost of new equipment. Trade-in allowance of existing equipment. Book value of existing equipment.

Exercise 32.12 - Enhanced - with Feedback Part A An electromagnetic wave with frequency 65.0 Hz travels in an insulating magnetic material that has dielectric constant 3.64 and relative permeability 5.18 at this frequency. The electric field has amplitude $7.20 \times 10^{-3}$ V/m. What is the speed of propagation of the wave? Express your answer in meters per second. $v = 1.03 \cdot 10^8$ m/s Submit Previous Answers Request Answer Incorrect; Try Again; 5 attempts remaining Part B What is the wavelength of the wave? Express your answer in meters. $\lambda =$ m Submit Request Answer Part C
V. Evaluate $\int_C |z|^2 dz$, where C is $x(t) = t^2$, $y(t) = \frac{1}{t}$, $t: 1 \to 3$ VI. Evaluate $\int_C (\bar{z})^2 dz$ on the contour shown here $\implies$ VII. Find $I = \int_C |iz^2| dz$ where C is the upper half of the ellipse $\frac{(Re \ z)^2}{4} + \frac{(Im \ z)^2}{9} = 1$ from +2 to -2. This one is challenging. Hint #1: Use polar form of the ellipse. Hint #2: Keep the table of integrals handy.
