The period is 5. Start at x = 0 and trace the curve until you reach the same height as when you were at x = 0 (which is y = 3). The function repeats itself over again once you get to x = 5.
The amplitude is 2.5 since it is half of the vertical distance from the peak y = 3 to the valley y = -2. This distance is 5 units, half of which is 2.5

You just need to see what letters and arrow matches the answer in the question.
The answer is 168. 12% is also 0.12. 150(0.12) is 18. 150+18=168
Answer:
³/5
Step-by-step explanation:
Total = 5 units
Girls = 3 units
~if ⅔ of the girls wear braces
= 2units of girs wear braces
Boys = 2 units
~if ½ of the boys wear braces
= 1unit of boys wear braces
Hence, 2units + 1unit =3 units of the class wears braces.
Total pupils = 5units
total that wear braces out of the whole class = 3/5
