The amplitude is the highest the function ever gets. That happens when the
cosine is ' 1 '. At that point, the value of the function is<em> 5/2 </em>.
The period is the first time after zero that the angle in the cosine is 2π .
x/2 = 2π
Multiply each side by 2 : x = 4π
The period is <em>4π .</em>
E is wrong. It only says twelve but it is a square and squares have the same side so u would really do twelve times twelve and get 144. And also I got 360 on the challenge one because u would split the irregular figure and you would do ten times nine equals ninety then nine times thirty equals 270. Then add it and you old get 360 m2
