Given transfer function, the identified correct steady-state response ys(t) to the given input function is: y (t) = 27.116 Sin (1.5 t - 49.4°)

<h3>What is a transfer function?</h3>

A transfer function is a mathematical link between a numerical input to a dynamic system and the subsequent output in statistical time-series analysis, signal processing, and control engineering.

<h3>What is the calculation justifying the above result?</h3>

Step 1

Recall that we are given T(s) = Ys)/F(s) = 75/(145 + 18)

⇒ T(Jw) = 75/ [18 + J14w]

This is called a steady state response to Sinusoidal input.

f(t) = [T(t) ↔T(jw)] → y(t A Sin (wi + φ)

Where A = A1 x [T(jw)] w= w1

⇒ A = A1 [T(jw1)]

And,

φ = θ + [T(jw)] w = w1

Step 2

Given, f(t) = 10 Sin 1.5t

A1 = 10, W1 = 1.5 red/see, θ = 0°

The Magnitude of T(jw) is

[T(jw)] = 75/√[(18²) + (14w)²

⇒ [T(jw] w = w1 = 1.5

= 75/√[(18²) + (141.5)²

⇒ [T(jw1)] = 2.7116

Hence,

A = A1 x [T(jw1)] =

10 x 2.7116

⇒ A = 2.116

⇒ Phase of T(jw) is,

[T(jw)] = - tan ⁻¹ (14w/18)

Hence, φ = 0° - Tan⁻1 (21/18)

φ = -49.4°

Hence,

y(t) = A sin (w1t + φ)

⇒ y (t) = 27.116 Sin (1.5 t - 49.4°)

From home, Mary’s work is two thirds along the way to training. Training is 2.5km from work. Mary normally goes to work, then tr
polet [3.4K]
First thing to do is to illustrate the problem, Since it was mentioned that work was along the way to training, the order is shown in the picture. Mary's home and workplace are nearer compared to her training center. It is also mentioned that the distance between work and home, denoted as x, is 2/3 of the total distance from home to training. The total distance is (x + 2.5). Thus,

x = 2/3(x+2.5)
x = 2/3 x + 5/3
1/3 x = 5/3
x = 5 km

Thus, the distance from home to work is 5 km. This means that Mary has to walk this distance twice to return home to get her shoes. Then, she will travel again the total distance of 5+2.5 = 7.5 km to get to her training center. So,

Total distance = 2(5km) + 7.5 km
Total distance = 17.5 km

The probability of a biased coin landing on heads is 2/7 complete the tree diagram
mamaluj [8]

Answer:

The numbers needed to fill each box are in the image attached

Step-by-step explanation:

The probability of the coin landing on heads is 2/7, so the probability of it landing on tails is 1 - 2/7 = 5/7

The probability of landing heads 2 times is:

P = (2/7) * (2/7) = 4/49

The probability of landing heads and then tails is:

P = (2/7) * (5/7) = 10/49

The probability of landing tails and then heads is:

P = (5/7) * (2/7) = 10/49

The probability of landing tails 2 times is:

P = (5/7) * (5/7) = 25/49

The numbers needed to fill each box are in the image attached.
