Question 2 - Signal and System Properties. State whether each of the statements is true or false. Note that a statement is true
gregori [183]

Answer:

  (a) true

  (b) true

  (c) false; {y = x, t < 1; y = 2x, t ≥ 1}

  (d) false; y = 200x for .005 < |x| < 1

Step-by-step explanation:

(a)  "s(t) is periodic with period T" means s(t) = s(t+nT) for any integer n. Since values of n may be of the form n = 2m for any integer m, then this also means ...

  s(t) = s(t +2mt) = s(t +m(2T)) . . . for any integer m

This equation matches the form of a function periodic with period 2T.

__

(b) A system being linear means the output for the sum of two inputs is the sum of the outputs from the separate inputs:

  s(a) +s(b) = s(a+b) . . . . definition of linear function

Then if a=b, you have

  2s(a) = s(2a)

__

(c) The output from a time-shifted input will only be the time-shifted output of the unshifted input if the system is time-invariant. The problem conditions here don't require that. A system can be "linear continuous time" and still be time-varying.

__

(d) A restriction on an input magnitude does not mean the same restriction applies to the output magnitude. The system may have gain, for example.

Help me find p.....​
asambeis [7]

Answer: p = 120 degrees

Step-by-step explanation:

Figure a shows a pentagon. The sum of interior angles in a pentagon is equal to 540 degrees.

1. Subtract the known numerical angle

540 - 60 = 480

All of the remaining angles (represented by the variable p) are equal to one another. Therefore, we can use the expression 4p = 480 to find the value of p.

2. Evaluate the equation to find the value of p.

4p = 480

p = 120

The manufacturer of computers spends $500 to make each computer and sells them for 800. The manufacturer also has fixed costs ea
ryzh [129]

Answer:

C(x) = 5700 + 500x

Step-by-step explanation:

Total cost = fixed cost + variable cost

Fixed cost are cost that do not change in the process of production such as machineries, furnitures & fittings.

Variable cost are cost that changes with production such as cost of raw material, cost of labor.

From the question:

Fixed cost= $5,700

Cost per unit of computer = $500

If x number of computers are produced in a month

Variable cost = 500x

Total cost = fixed cost + variable cost

C(x) = 5700 + 500x

Where,

C(x) = total cost

5700= fixed cost

500x= variable cost
