Increasing. It helps to graph it out.
Answer:
a) Sinusoidal functions are y = a sin [b(x-h)] + k (or)
y = a cos [b(x-h)] + k
Where a is amplitude a= (max-min)/2=(16-2)/2=7
period p= 2π/b
b=2π/30
Horizontal transformation to 10 units right h=10
k= (max+min)/2=(16+2)/2=9
h = 7 cos [π/15(t-10)]+ 9
b) t=10min=600 sec
substitue in the above equation
h=5.5m
Answer:
C 5/4 s
Step-by-step explanation:
Answer:
I think its D
Step-by-step explanation:
the first line in the chart has x as 0 and Y as 25
this means the fixed amount would be $25
