Answer:
11 meters
Step-by-step explanation:
Use the formula:

V = 7599, h = 20, π = 3.14
Plugin the numbers and solve for r

Answer:
a. 
Step-by-step explanation:
The given equation is;

To solve by the x-intercept method we need to graph the corresponding function using a graphing calculator or software.
The corresponding function is

The solution to
is where the graph touches the x-axis.
We can see from the graph that; the x-intercepts are;
(-1,0),(3,0) and (6,0).
Therefore the real solutions are:

Answer:
It's the last one (-14) +(-8)
Step-by-step explanation:
since (-14)-8 is -22 and the last one is also -22
Answer:

Step-by-step explanation:
To solve, first subtract 2x from both sides.

You appear to want the solution for -y, so I've included it. Given that you also want the solution for y, divide both sides by -1.
