Chem Labs uses raw materials I and II to produce two domestic cleaning solutions, A and B. The daily availabilities of raw materials I and II are 100 and 120 units, respectively. One unit of solution A consumes 0.3 unit of raw material I and 0.6 unit of raw material II, and one solutions B uses 0.5 unit of raw material I and 0.8 unit of raw material II. The profits per unit of solutions per unit of solutions A and B are $8 and $10, respectively. The daily demand for solution A lies between 30 and 150 units, and that for solutions B between 40 and 200 units. Find the optimal production amounts of A and B.Determinate the decision variables, objective Function and Constraint.
if you use the sinusoidal waveform to drive the speaker: What change in the sound do you expect to hear when you increase the amplitude of the sinusoidal signal on the function generator
Explain briefly why a capacitor can block DC voltage. How might you use this feature in a design. Explain why the impedance Zeq of a parallel RC circuit decreases as the frequency increases.
An AM signal has an unmodulated carrier voltage VC = 10VP, a load resistance of RL = 10, and a modulation index of m = 1. Determine Write down the frequency components of the received AM signal.
a certain radio frequency generator delivers a power level of 12 dBm. If this signal is amplified, calculate how many decibels of gain is required to produce a power of 20 dBm.
We will make the follwoing probability assumptions: When team A plays team B, the probability that team A wins is given by: P(A wins) = \(([seed(B)+3]^2)/([seed(A)+3]^2 +[seed(B)+3]^2) \)
The steering wheel has backlash. This means there is a delay between the time the wheel is turned, and the time the car responds. The driver tends to overturn, which leads to instability and lack of control of the car.
a particular electric utility charges customers different rates depending on their daily rate of energy consuption 0.05khw up to 20 kwh and 0.1 kwh for all energy usage above 20 kwh in any 24 hour period.
Assume for now that all components are powered up simultaneously and that event detection is instantaneous. This means that one does not need to consider sampling or processing time. Also, all three sensors are required for unambiguous event detec..
Derive equations for the capacitance, and resistance across the dielectric of a coaxial line of inner conductor radius a, and outer conductor radius b, and permittivity ε.
Write a 68000 assembly language subroutine, ROTMEM, which rotates the elements (words-size) of an array stored at location point to by (A0). The depth of the array is stored as the first element.
Find a minimum two level circuit (corresponding to the sum of products expressions) using AND and one OR gate per function for each of the following sets of functions: f(a,b,c,d) =fm(1,3,5,8,9,10,13,14) g(a,b,c,d) =fm(4,5,6,7,10,13,14)
