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
A three-phase transmission line having a reactance of 120 ohms per phase is connected to a wye-connected load whose resistance is 160 ohms per phase. If the supply volatge is 70kV line-to-line, calculate a) The line-to-neutral voltage per phase.
Design a circuit that will multiply the input voltage by +12. That is the output voltage is 12v1 where v1 is the input voltage. All resistors should be at least 12ohms.
On Earth, we assume normal room temperature is 293 degrees Kelvin. From this, we find that the power spectral density of thermal noise is -174 dBm/Hz. On Venus, the average surface temperature is 462 degrees Celcius.
Pulse Generator, Using one 555 timer, design a pulse generator that will have the following continuously variable ranges
In a voltage stabilizer circuit with a Zener diode, the output voltage decreases when touching the zener diode with your fingers when no load is connected. Ideally, the output voltage should not drop. Explain why there is a decrease in output volt..
