Multiply by 4 to get rid of fraction
4(18) = 4(x/4 + 7)
72 = x + 28
x = 44
Solution; x = 44
|x| < 7
means x < 7 and x > -7
answer is -7 < x < 7
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
Answer:
11/12
Step-by-step explanation:
according to this calculator thats the answer ... hope this helps
