Total Population= 11800÷26
Step-by-step explanation:
- Number of animals captured,tagged and released= 118
- In capture/recapture program 26% have tags
     i.e, 26% of total animals= 118 
     Let total number of animals = P
       (26÷100)× P =118
       26 P =118×100
             P=11800÷26

Answer:
(-3, 4)
Explanation:
 Reflection over the x -axis is (x,y) → (x,−y)
Here the given point:
N(-3, -4)
If reflected:
(-3, 4)
 
        
                    
             
        
        
        
Vertex aka max or min point is found by -b/2a in form
f(x)=ax^2+bx+c
f(x)=-1x^2+8x+20
vertex x value is -8/(2)(-1)=-8/-2=4
input back to find y value
f(4)=-(4^2)+8*4+20
f(4)=-16+32+20
f(4)=36
max (since the graph opens down) is (4,36)
axis of symmetry is the x coordinate
max is (4,36)
axis of symmetrry is x=4
