how to find the period, amplitude, and vertical shift of a sinusoidal graph. please explain in the simplest way possible, tyyyy
Kay [80]

Answer:

Step-by-step explanation:

a) period is the length of one cycle  ( one full squiggle ) If you are lucky and the graph is on exact numbers.. at a high point and to the next high point.. then just take that horizontal distance,  that's one period  also if it's not  you could find the period, T,  by using  T = 2pi / k    where k is a number that represents how fast , or how many times the wave cycles in one second or some other amount of time.  

b) Amplitude is a number that goes right before the sinusoid, which is multiplied by it because,  sin , cos,  are at max 1 or at min -1  

c)  vertical shift is what is added , for upwards shift... before or after the                      sinusoid  ie  sin , cos,  ect ect.

does this help?

Slide and transformation
Ludmilka [50]

The rule that describes this transformation is (x - 3, y + 1)

Step-by-step explanation:

Step 1:

The points of the trapezoid are

M; (-3, -1),

N; (-4, 3),

P; (1, 3), and

Q; (-1, -1).

Step 2:

To translate the points to 3 units on the left, we subtract the x coordinate by 3 because it is moved to the left. So x becomes x - 3.

In order to translate the points to 1 unit up, we add 1 to the y coordinate as it is moved in the positive direction of y. So y becomes y + 1.

Combining these we get (x, y) becomes (x - 3, y + 1).

George created a table based on two charged objects.
docker41 [41]

Answer:

Two negative charges will not attract each other.

Step-by-step explanation:

According to the law of electrostatic induction, it states that "Like charges repel, unlike charges attracts.

Charges can either be positive or negative. For the charges to repel, charges with the same sign must be brought together e.g positive-positve or negative-negative.

For the charges to attract, charges with different sign must be brought together e.g positive-negative or negative-positive.

Based on the conclusion above, it can be seen that the table is incorrect because two negatively charged particle will always repel not attract.

The graph of f(t) = 4.2 shows the value of a rare coin in year t. What is the
12345 [234]

<u>Given</u>:

The graph of f(t)=4 \cdot 2^t shows the value of a rare coin in year t.

We need to determine the meaning of the y - intercept.

<u>Meaning of the y - intercept:</u>

Here, t represents the x - axis and f(t) represents the y - axis.

The value of y - intercept is the value of y when x = 0.

Hence, the the value of f(t) can be determined by substituting t = 0 in the function f(t)=4 \cdot 2^t

Thus, we have;

f(0)=4 \cdot 2^0

f(0)=4

Thus, the value of the y - intercept is 4.

The y - intercept represents the value of the rare coin in year 0.

Therefore, the meaning of the y - intercept is "When it was purchased (year 0), the coin was worth $4".

Hence, Option B is the correct answer.
