Fh. = 40h + 120, fh. = $200
200 = 40h + 120
200 - 120 = 40h
80 = 40h
80/40 = h
2 = h
h = 2 hours.
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:
yes,it is
Step-by-step explanation:
Answer:
x >=-2
Step-by-step explanation:
-10x <= 5
divide each side by -10
remember to flip the inequality when dividing by a negative
-10x/-10 >=5/-10
x >=-2
