Write a cosine function that has an amplitude of 2, a midline of 5 and a period of \frac{3\pi}{4} 4 3π ​ .

Given:

Amplitude = 2

Midline = 5

Period of .

To find:

The cosine function.

Solution:

The general cosine function is:

           ...(i)

Where, |A| is amplitude, is period, is phase shift and D is the mid line.

Period of function is . So,

Substituting in (i), we get

Therefore, the required cosine function is .

answer:

125 yards

explanation:

75+50=125. that is my answer

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
