Question

Write a cosine equation to model the height of the red spot over the distance you ride

Answer 1

Given:

There are given that the radius of the tire is 11 inches, the circumferences of the tire is:

`2\pi r`

Explanation;

From the concept of cosine equation:

A cosine equation or formula is one of the three most common trigonometric functions.

It is the trigonometric function that equals the ratio of the side adjacent to an acute triangle to the hypotenuse.

So,

According to the above concept:

The cosine equation is:

`y=11cos\lparen(1)/(11)x)+11`

Final answer:

Hence, the correct option is A.
