Answer:

Step-by-step explanation:
The formula of a volume of a cone:

r - radius
H - height
We have r = 10cm and H = 16cm. Substitute:

 
        
             
        
        
        
Answer:
a
Step-by-step explanation:
Domain means the change in x. 
so the domain will be which values of x the fn goes through. 
you can see the black line goes from -9 to 2 in x values. 
the -9 isn't filled in, but the 2 is. filled in means it will be with an equals instead of without. 
so x is between -9 and 2, 2 is with equals -9 is without,
so the first one.

Explanation
Problem #2
We must find the solution to the following system of inequalities:

(1) We solve for y the first inequality:

Now, we multiply both sides of the inequality by (-1), this changes the signs on both sides and inverts the inequality symbol:

The solution to this inequality is the set of all the points (x, y) over the line:

This line has:
• slope m = 3/2,
,
• y-intercept b = -2.
(2) We solve for y the second inequality:

The solution to this inequality is the set of all the points (x, y) below the line:

This line has:
• slope m = -1/3,
,
• y-intercept b = 2.
(3) Plotting the lines of points (1) and (2), and painting the region:
• over the line from point (1),
,
• and below the line from point (2),
we get the following graph:
Answer
The points that satisfy both inequalities are given by the intersection of the blue and red regions:
 
        
        
        
Answer:
Not proportional
