Y=kx is the direct variation equation
First plug in the x, y values given to find K 
18=k(5)
18/5=k
3.6 = k
Use the k and write a new equation. 
y=3.6x
Plug in the x value to solve for y. 
y = 3.6(11)
y= 39.6
        
             
        
        
        
Answer:
1385.28 m²
Step-by-step explanation:
apothem = √16² - 8² = √256 - 64 = √192 = 13.86
Base area = 3 x 16 x 13.86 = 665.28
6 side area = 3 x 16 x 15 = 720
surface area = 665.28 + 720 =1385.28
 
        
             
        
        
        
Answer:
C. 
Step-by-step explanation:
The formula for a cylinder is V = (pi) (r^2) (h) so 12*12 is 144. 144*pi*17 is 2448 pi units cubed. 
 
        
             
        
        
        
The graph of a function is given. It is required to find the function that represents the graph.
Notice from the graph that the function has roots or zeros at -3,-2, and 2.
Hence, the function takes the form:

Where a is a constant to be determined.
Notice that the given graph passes through the point (0,-12).
Substitute x=0 and f(x)=-12 into the equation of the function to find a:

Hence, the function is:

<h2>
The third option is the answer: f(x)=(x+2)(x+3)(x-2).</h2>
 
        
             
        
        
        
Answer:
Step-by-step explanation:
yes, since that are 2 points:
y-int is (0, y)
x-int is (x, 0)
since you need only two points for a function with no restrictions, we can use y and x intercepts as points
