What is the general equation of a sine function with an amplitude of 2, a period of pi and a horizontal shift of pi units?

The general form of the sine function is

Explanation:

The general form of a sinusoidal function is in the form

Here, A = amplitude

C = Horizontal shift

D = Vertical shift or mid line

The formula for finding the period is

Further Explanation:

It has been given that, the amplitude is 2. Thus, A = 2

Now, the period is π. Thus, we can use the formula for period for finding the value of B.

Therefore, the value of B is 2.

Now, since the variable c is phase shift or horizontal shift and it has been given that horizontal shift is π units.

Thus, C = π

Therefore, the general form of the sine function is

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

d

step-by-step explanation:

the 2000 florida legislature amended section 322.05, florida statutes, changing the requirements to obtain a class e license for a driver under the age of 18 holding a learner's license. the following requirements must be met in order to obtain a regular class e license if a learner's license is issued on or after october 1, 2000:

must hold a learner's license for at least 12 months or until the 18th birthday.

must have no convictions 12 months from the issue date of the learner's license.

may have one traffic conviction within 12 months from the issue date of the learner's license if adjudication is withheld.

a parent, legal guardian, or responsible adult over 21 years old must certify that the driver has 50 hours driving experience, including 10 hours of night time driving.
