In the function f(t) = sin(t), what is the effect of multiplying t by a coefficient of 2?
liubo4ka [24]

Answer:

"changes the period to pi"

Step-by-step explanation:

f(t) = Sin(t),

Here, t is the period, by definition.

Multiply t by a number that is GREATER THAN 1, makes the period shorter and compressed.

Multiplying t by a number that is between 0 and 1 makes the period expanded.

For the first, if we multiply the period by a, the period becomes \frac{2\pi}{a}

Since the problem tells us to multiply by 2, we know the period becomes compressed and becomes :

\frac{2\pi}{2}=\pi

Third answer choice is right.

Suppose you add two vectors A and B . What relative direction between them produces the resultant with the greatest magnitude? W
Anna71 [15]

Answer: The resultant would be the sum and the difference between the vectors.

Step by step explanation: 1. The possible resultant is between the sum of the 2 vectors and the difference between the two vectors.

2. The greatest magnitude is when the vectors lie in the same direction and the sum would be the scalar sum of the two vectors. The angle between the two would be zero degree.
