Answer:

A. 2

Step-by-step explanation:

When adding two numbers, you are combining their values.

In this problem, you are combining the value of 1 with the value of 1. When you combine them, you are saying that you have two 1's. So in this problem, you combine both ones and get a final answer of 2.

A sinusoidal carrier wave is used in the modulation process to move the information signal to a higher frequency for transmission. Identify the carrier variable(s) that can be modified to represent the original information signal. g

Answers

Answer:

A - amplitude

f - frequency

Q - phase

Step-by-step explanation:

A sinusoidal carrier wave can be represented as follows: f(x) = Acos(2pi*f + Q)

So to represent the original information, you can modify the following variables mentioned above. If they looking for just one variable, then use the frequency.

Find all solutions to the equation

7 sin^2x - 14 sin x + 2 = -5

Answers

7 sin^2(x) - 14 sin(x) + 2 = -5
Temporarily substitute y in for sin(x) to make it more readable
7y^2 - 14y + 2 = -5
Move the -5 over by adding to both sides
7y^2 - 14y + 7 = 0
Simplicity by dividing both sides by 7 to get
y^2 - 2y + 1 = 0
Factor to get
(y-1)(y-1) = 0
Or y-1 = 0
y = 1
Therefore
Sin(x) = 1
x = pi/2 + 2pi * n where n represents all whole numbers
Final answer:
x = pi/2 + 2pi * n

Find the value of x and y in each triangle

Answers

The value of variables are,

⇒ x = 13.85

⇒ y = 16

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

Base of triangle = 8

Now, We get;

⇒ cos 60° = 8 / y

⇒ 1/2 = 8/y

⇒ y = 8 × 2

⇒ y = 16

And, By Pythagoras theorem we get;

⇒ x² + 8² = y²

⇒ x² + 8² = 16²

⇒ x² + 64 = 256

⇒ x² = 256 - 64

⇒ x² = 192

⇒ x = √192

⇒ x = 13.85

Thus, The value of variables are,

⇒ x = 13.85

⇒ y = 16
