The percentage change in the number of stamps is 140%.

Step-by-step explanation:

We are given the following information in the question:

Number of stamps added = 42

Initial number of stamps = 30

Total umber of stamps = 72

Formula:

Percentage change =

$\displaystyle\frac{V_2-V_1}{V_1}\times 100\%$

Putting the values, we have:

$\displaystyle\frac{72-30}{30}\times 100\%\\\\=\frac{42}{30}\times 100\%\\\\=140\%$

Hence, the percentage change is 140%.

sin 0 = 0

sin 90 = 1

sin 180 = 0

sin 270 = -1

sin 360 = 0

So its Graph C.
