7:46 PM Mon Sep 29 HW1 1 of 4 1. Three chains act on a bracket such that they create a resultant force having a magnitude of 500 lbf (direction is unknown). If the forces in two of the chains are known (both magnitude/direction), determine the angle $\theta$ of the third chain, so that the magnitude of force F in this chain is a minimum. What is this magnitude F in terms of lbf? (25 Points) y 300 lb 30° x θ F 200 lb 80% Done

Investor X invested $2,500 ten years ago and expected to have $7,500 today. They have neither added nor withdrawn any money since their initial investment. All interest was reinvested and compounded annually. As it turns out, they have only $6,800 in their account today. Which one of the following statements must be true? Multiple Choice The interest rate and the number of compounding per year turned out to be higher than expected. They ignored the Rule of 72, which caused the account to decrease in value. They earned simple interest rather than compound interest. They did not earn any interest on interest. They earned a lower interest rate than expected.

1. Design the band pass filter whose desired pass frequency is from 0.1 rad/s to 100 rad/s. Then evaluate the performance of the bandpass filter using MATLAB. 2. Design the band reject filter whose desired reject frequency is from 0.1 rad/s to 100 rad/s. Then evaluate the performance of the bandpass filter using MATLAB. 3. Design the low pass filter whose desired bandwidth frequency is 200 rad/s. Then evaluate the performance of the bandpass filter using MATLAB. 4. Design the high pass filter whose desired cut-off frequency is 200 rad/s. Then evaluate the performance of the bandpass filter using MATLAB.

A function and its graph are given. Use the second derivative to determine each of the following. Check your results against the graph shown. $f(x) = \frac{1}{4}x^4 + \frac{1}{2}x^3 - 3x^2 + 8$ f(x) 20 15 10 5 -8 -6 -4 -2 2 4 6 8 x -5 -10 -15 -20 Determine intervals on which the function is concave up. (Enter your answer using interval notation.) Determine intervals on which the function is concave down. (Enter your answer using interval notation.) Locate the points of inflection. (If an answer does not exist, enter DNE.) $(x, y) = ($ (smaller x-value) $(x, y) = ($ (larger x-value)
