Hello, you haven't provided any continuous-time system, therefore, I am going to explain to you how to solve this problem in general and you can apply this to your system or any continuous-time system.

Answer step-by-step explanation:

  • Linear: A system is linear if it obeys the principle of superposition Z{aX1(t)+bX2(t)}=aZ{X1(t)}+bZ{X2(t)}=aY1(t)+bY2(t), where Z is an operator which maps the input into output (Z is the system itself)
  • Causal: A system is causal if it doesn't depend on future inputs Y(t)=Z(x(t)) up to time t
  • Time-Invariant: A system is time-invariant if a time-shift on the input causes a equivalent shift on the output, if Y(t)=Z(x(t)) then Y(t-t0)=Z(x(t-t0))
  • Stable: A system is stable if every bounded input produces a bounded output, abs(Y(t))<B if abs(X(t))<A / abs(A) < inf and abs(B) < inf
  • Memoryless: A system is memoryless if its output at time t is dependent only on the input at that time, Y(t) at time t depends only on X(t) at time t
  • Invertible: A system is invertible if we can get back the input by passing the output through another system (No information loss)

Joey puts 25% of his allowance into savings each week. If last week he put 10$ in savings, what was his allowance last week?​
GrogVix [38]

Answer:

$40

Step-by-step explanation:

25% is 1/4.

If 10 is 1/4 of the full amount, then you take 10 and multiply by 4 to get the full amount.

10 times 4 equals 40.

The bearing of point B from point A is 064°.<br> Find the bearing of point A from point B.
Alex777 [14]

Answer:

The bearing of A from B is 296 degrees

Step-by-step explanation:

Here, we want to find the bearing of point A from point B

To find the bearing of point A from B, we simply subtract the bearing of B from A from 360

Mathematically, that will be;

360 - 64 = 296 degrees
