Seeing the graph from desmos.com, we know there is only one place where the graph will go up then down, or down then up given that the maximum exponent of x is it squared. That place, as seen, is -0.375 for the minimum as it goes down then up. There's no maximum in sight :(
 
        
        
        
Answer:
tan(-π/3) =  -1.732050808
Step-by-step explanation:
Given in the question, we have to find the value of tan(-pi/3) or it can be written as:

where x is the exact value of the given tangent.
However, in this question, one may get confused and put the value of π = 3.14, which is wrong. The value given is in radians, which is used to measure angles, just like degrees.
To make it easier, lets convert the radians into degrees. We know that 
π = 180°
-π/3 = -180/3 = -60°
Find x:
x = tan (-60°)
x = -1.732050808
 
        
             
        
        
        
Step-by-step explanation:
One gallon = 25 miles 
8 gallon= 25×8 miles= 200 miles
 
        
             
        
        
        
From principle of floatation:
W = U
The volume of water displaced is as a result of the volume of object submerged. 
The wood would also float with 1/4 of its total height or total volume below the water surface.
