The answer i think is A hope that help 
        
             
        
        
        
24 * 3/4 = 18
The radius of smaller cone is 3/4 the radius of original cone, so since these cones are similar, height must also be 3/4 times smaller.
So since radius is squared and we also multiple the height (V = 1/3 π r² h),
the volume of smaller cone would be 3³ / 4³ = 27 / 64 times smaller
So we have 1920 * (27 / 64) = 810.
Final answer: B
        
             
        
        
        

 will be increasing on the intervals where 

 and decreasing wherever 

. Local extrema occur when 

 and the sign of 

 changes to either side of that point.

 is positive when 

 is between -4 and some number between -2 and -1, and also 2 (exclusive) and 4, so you can estimate that 

 is increasing on the intervals [-4, -2] and (2, 4].

 is negative when 

 is between some number between -2 and -1, up to some number less than 2. So 

 is decreasing on the interval [-1, 1].
You then have two possible cases for extrema occurring. The sign of 

 changes for some 

 between -2 and -1, and again to either side of 

.
 
        
             
        
        
        
Answer:
y + 2 = (-4/5)(x - 3)
Step-by-step explanation:
Your slope is -4/5.  Your line passes through (3, -2).
Applying the point slope formula, we get:
y + 2 = (-4/5)(x - 3)
 
        
                    
             
        
        
        
Answer:
b
Step-by-step explanation:
The sum of angles in a triangle is 180°. Therefore,
x - 11 + 48 + 90 = 180
x + 127 = 180
x = 53°
