Answer:
Choice A
Period = 4
Amplitude=2
Step-by-step explanation:
From the graph you can see that the graph of the function periodically repeats ecah 4 units. This means that the period of the function is T=4.
The range of the function is [-4,0]. The midpoint of the range is y=-2. When you draw the line =-2, you can see that the graph is 2 units above the line y=-2 and 2 units below the line y=-2. This means that the amplitude is 2.
Let selling price = SP and cost price = CP
He makes 20 % on selling price means = >
(sp-cp) / sp = 20 % = 20/100 = 0.2
(sp - cp) / sp = 0.2
1 - cp/sp = 0.2
1 - 0.2 = cp/sp
0.8 = cp/sp
Reversing 1 / 0.8 = sp/cp = 1.25
We need to find profit on cost price means =
=(sp-cp)/ cp
= sp/cp - 1 = 1.25 - 1 = 0.25
Means 25 % profit on cost price : Answer
Hope that will help :)
