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.

Grace's walking rate is 1.5 meters per second. Her house is 90 meters from the fountain. How many seconds will it take her to reach the fountain?
Answer: We know that Grace's walking rate is 1.5 meters per second
Number of meters Grace's house is from fountain is 90 meters.
Therefore, the time it will take Grace to reach the fountain is:
Therefore, it will take Grace 60 seconds to reach fountain
Speed=1.5
Distance=90 meters
Time=?
Distance= time × speed
Thus,
T=distance/speed
=90/1.5
= 60 second
= 1 minute

Answer:
d(x) = √[(x - 2)² + (3x - 1)²]
Step-by-step explanation:
The distance between two points with coordinates (x₁, y₁) and (x₂, y₂) is given as
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
So, the distance between point (2,0) and a point (x,y)
d = √[(x - 2)² + (y - 0)²]
d = √[(x - 2)² + (y)²]
But the point (x,y) is on the line y = 3x - 1
We can substitute for y in the distance between points equation.
d(x) = √[(x - 2)² + (3x - 1)²]

Determine the axis of symmetry, x =
Answers
Answer:
Step-by-step explanation:
We have the quadratic function:
And we want to determine its axis of symmetry.
Notice that this is in vertex form:
Where (h, k) is the vertex of the parabola.
From our function, we can see that h = 4 and k = -2.5. Hence, our vertex is the point (4, -2.5).
The axis of symmetry is equivalent to the x-coordinate of the vertex.
The x-coordinate of the vertex is 4.
Therefore, the axis of symmetry is x = 4.
