You have just graduated from college, and your personal goal is to retire in 40 years, when you are about 62 years of age. To do so, you think you will need to have amassed $10,000,000 on the date of your retirement. Your parents plan to gift $36,000 annually to you, and you plan to save an additional $15,000 annually from your wages. Assume you invest the annual $36,000 gift from your parents and your annual $15,000 of savings at the end of each year at an 8% rate. a. Show calculations to determine whether you will have enough in 40 years to meet your $10,000,000 retirement goal. b. Show calculations to determine the exact rate of return on your annual investments of gifts from your parents combined with your annual savings that will result in exactly $10,000,000 in 40 years. (Round your answer to the nearest tenth of a percent.) Mortgage amount: $630,000 Term: 30 years (360 months) Annual fixed interest rate: 6.0% (.5% per month) Payments are due monthly at the end of each month. The monthly payment is the same amount over life of the loan; the loan is fully amortizing.

What happens if the two initial lines of defense of our body cannot adequately protect us from a disease-causing pathogen? Nonspecific immunity develops and recognizes pathogens by relying on commonalities among different pathogens. Adaptive immune responses occur and memory toward the specific pathogen develops. The body must rely on medication as there is no natural recourse if the two initial lines of defense of our body fail. Innate immunity develops and is enhanced after contact with a specific pathogen and protects the organism upon subsequent exposure to that particular pathogen.

A quadrature encoder has 2000 pulses per revolution. You will connect a roller to the encoder to ride on a linear surface. You want an output of 1000 pulses per inch. What should the diameter of the roller be? Question 3. You have a 10 turn 100kOhm potentiometer, and a linear slide that travels 24 inches from end to end. The potentiometer is driven by a rack and gear. The rack has 64 teeth per inch. For the full travel of 24 inches, the potentiometer should make 8 turns. How many teeth should the gear have? 24 inches Number of teeth? 64 teeth/inch Assume 24VDC is applied across the pot, and the potentiometer is centered at the 12 inch point of the table. What will the voltage readout be at the center of travel, and at each end of travel? Question 4. Your PLC has an analog input card that has 12 bit resolution and measures from 0-20mA. If you select a Pressure Sensor that has a range of 0-3000 psi for an output of 4-20 mA, what is the smallest pressure change that you can sense?
