A lottery winner got $350,000 that invested as follows: part of it in a money market account, part in municipal bonds, and part in a mutual fund. After one year, he recieved a total of $24,200 in simple intersest from the three investments. The money market paid 6% annually, the bonds paid 7% annually, and the mutually fund paid 8% annaully. There was $40,000 more invested in the mutual funds than in bonds. Find the amount this person invested in each category. To solve the problem follow the following step:a) write the system of equations that describes this problem. Identify clearly unknowns.b) Express the sysem of equation in matrix form.c) write a matlab script that will calculate :i) the determinant of the system, and if the determinant is different from zero,ii) find the inverse of the system matrixiii) using the inverse,solve for the unknowns
Design an active low pass filter with a cutoff of 10kHz or more by more than 30db and have the pass band gain positive that does not deviate from 20db by more than 3 db. The pass band frequncy need is 800Hz and below.
where the assigned loop current leaves the voltage source. If current leaves the voltage source at its positive terminal, the voltage would be positive and if it leaves the voltage source at its negative terminal,the voltage would be negative.
The speed of a 10HP, 230V, 1200 rpm separately excited DC motor is controlled by a 1-phase full-wave bridge converter. The rated armature current of the motor is 10 A. The armature resistance is 0.25 Ohm and the armature inductance is 10 mH.
A three-phase, 60Hz, wye-connected synchronous generator has balanced line-to-line voltages of 480V at its terminals. The generator is supplying power to two balanced and delta connected, three-phase loads. the first load is made up of three.
The maximum voltage that James can apply to this capacitor is limited by Vmax = Kd, where K is the breakdown strengh of the dielectric. deriven an expression for the maximum energy that can be stored in this capacitor in terms of K and the volume ..
The reliability performance of each microprocessor is based on the exponential reliability distribution with the following failure rates: A = 23.5 × 10^-3 , B = 12.5 × 10^-4 , C = 12.5 × 10^-4 and D = 23.5 × 10^-3
A 600kVA, 600 V, 0.9-PF-leading, Y-connected synchronous motor has a synchronous reactance of 1.0 per unit and an armature resistance of 0.1 per unit. At the current time, EA = 1
The motor driven by a switch-mode dc-dc converter, which has a bus voltage of 200V. The switching frequency fs = 25 kHz. Calculate and plot the waveforms for va(t), ea(t), ia(t), and id(t) under the following conditions
The detector will take in numbers from 1510 to 010 encoded in binary labeled [N3:N0] with N3 being the most significant bit. The output will be asserted when the decimal value of the input is a prime number (i.e., 2,3,5,7,11,13). The output is de-..
Given a two-dimensional array named number of three rows and four columns of type int, write the single code statement that will both declare and initialize the array such that the first row is initialized to 0, 1, 2, 3
Determine the relationship between the steady-state error to a ramp input and the gain K and system parameter b. For what values of K and b can we guarantee that the magnitude of the steady-state error to a ramp input
Which requires more harmonics to accurately model it (triangle, square, and sawtooth) and why?
