If your graph is a COS or SIN graph :

a is the Amplitude
and period is:

If your graph is a TAN graph :

A TAN graph has no amplitude as it has no Maximum or Minimum value.
To find period :
Answer: 62+63+64
Step-by-step explanation:
Divide 189 by 2. That gives you 63. Then go for a number 1 above it and 1 below it.
<span>D = 22ft
h = 9 ft
Lateral area of the cylinder = </span>π × D × h = 3,14 × 22 × 9 = 621,72 ft²
the second is a negative slope due to the fact the line is going the the left and the ind variable is breakfast dep is performance
