Answer:
- maximum: 40
- minimum: -10
- midline: 15
- amplitude: 25
- rate constant: ??
Step-by-step explanation:
The maximum value is the y-coordinate of the most extreme point in the positive direction. On this graph, it is 40.
The minimum value is the y-coordinate of the most extreme point in the negative direction. On this graph, it is -10.
The midline is the line halfway between the maximum and minimum. Its y-coordinate is the average of the maximum and minimum: (40-10)/2 = 15.
The amplitude is the difference between the maximum and the midline:
40 -15 = 25.

The term "rate constant" is used for many things, but is rarely seen as a descriptor of a sine function. For that, you'll need to <em>consult your text</em> or other reference material. (Google turns up kinetic rate constants, chemical reaction rate constants, and others—nothing related to sine functions.)
The usual descriptors are frequency or period. (Frequency is the reciprocal of period.) On this graph, the period of the function is 6 units, so the frequency is 1/6 cycles per unit.
