okay im not sure but maybe try to find a number that can be = to 18 and that might be y
Answer:
2:5
Step-by-step explanation:
david=24mins
mark = 1hour
change 1 hour to mins
DAVID=24
MARK=60
24:60
THEN SIMPLIFY
24/60
<em>=</em><em>2</em><em>/</em><em>5</em>
<em><u>2</u></em><em><u>:</u></em><em><u>5</u></em>
The period is 2.
Normally the period of sin(x) is 2pi, but the pi inside the sin(pix) is a horizontal compression by a factor of 1/pi. So 2pi·1/pi = 2
The "1/2" and "+3" do not impact the period. Those just impact the amplitude (vertical aspect) of the graph.
