Answer:

Step-by-step explanation:
All the relations are not functions. We can determine ( identify ) whether a relation is function or not by drawing a vertical line intersecting the graph of the relation. This is called vertical line test.
- If the vertical line intersects the graph of a relation at one point , the relation is a function .
- If it cuts at more than one point , it is not a function. It means that if there are more points of the graph of a relation of a vertical line , same first component ( pre - image ) has more images ( second component ) which is not the function by definition.
--------------------------------------------------
Let's check all of the options :
☐ Option A : 
- The vertical line cuts the graph at two points. So , the graph does not represent a function.
☐ Option B 
- No! This is also not a function as the vertical line cuts the graph at two points.
☐ Option C 
- Nah! This too can't be called a function as the vertical line cuts the graph at two points.
☑ Option D
- Yep! The vertical line cuts the graph at one point. Thus , the graph represents a function.
Yayy!! We found our answer. It's ' Option D '.

Answer=16ft
√256=16ft
length=16ft
        
                    
             
        
        
        
We are given 
sequence is 2 , 4 , 8 ,16 , 32 , .....
Firstly , we will check whether it is geometric sequence
Checking geometric sequence:
We will find common ratio between successive terms 
and then we check whether they are equal
r1=(second term)/(first term)

r2=(third term)/(second term)

r3=(fourth term)/(third term)

r4=(fifth term)/(fourth term)

we can see that all four ratios are same

so, this is geometric sequence 
Calculation of general term:
We got 
common ratio is 

Let's assume 
number of terms is n
first term is 2

now, we can use formula 

we can plug values
and we get

volume cylinder
=3.14×2^2×5
=62.8 cubic inches
volume sphere
=4/3×3.14×2^3
=33.49
difference between cylinder and sphere
=62.8-33.49
=29.31 cubic sphere
