Answer:
2
Step-by-step explanation:
From the graph, we obtain the trigonometric function as:

The corresponding cosine function have equation.

This function is of the form: 
where
is the amplitude.
Therefore the amplitude is |2|=2
The third choice is correct

Answer:
The correct answer is option C. 75 m³
Step-by-step explanation:
<u>Points to remember</u>
Volume of rectangular prism = Base area * Height
<u>To find the volume of given prism</u>
Here Base area = 15 m² and
Height = 5 m
Volume = base area * height
= 15 * 5
= 75 m³
Volume of prism = 75 m³
Therefore the correct answer is option C. 75 m³
You don't know your terms I suppose.
Arithmetic: goes from one term to the next by adding or subtracting the same amount
Ex. 3,12,21,30,39 (d=9)
(d means difference, use this for arithmetic sequences)
Geometric: goes from one term to the next by multiplying or dividing by the same amount
Ex. 1,2,4,8,16,32,64,128 (r=2) (r means ratio, its just the number multiplied or divided each time)
