Cot^2x - cot^2x cos^2x
= cot^2x - {(cot^2x)(cos^2x)}
= cot^2x { 1 - cos^2x }
= cot^2x { sin^2x }
= (cos^2x/sin^2x) { sin^2x }
= cos^2x

<span>16=4² 
25=5² 
</span>So that means the square root of 22 is between 4 and 5.
Square 4.5 
4.5² = 20.25 
<span>4.5 < √22 < 5 
So the nearest whole number would be 5.

Answer:
7(x)=5x+7
to find the x / zero intercept, plug in f (x) = 0 
0=5x+7
move the left side and change the sign 
-5x7
divide both of the equation by -5
x= 
same steps for g(x)=-2x-4
x=-2
 
        
             
        
        
        
Answer:
0, -1, -3
Step-by-step explanation:
f(x) = y = height of the line plotted
if you treat the x axis as the "ground" or "floor"....you're looking for the point when the graph "hits" the "floor", meaning zero height.
