Y=Acos(p)+m, A=amplitude, p=period, m=midline, in this case:
A=1/2, p=360(t/12)=30t, m=(10-9)/2+9=9.5 so
h(t)=(1/2)cos(30t)+9.5
You can do anything between .50 and .75. For example .55. .55=55% .55 also equals 11/20 as a fraction
Eleven plus
t minus seventeen
ten multiplied by n
fifteen multiplied by y
four multiplied by x
a plus b
fourteen times x plus three times y
