Step-by-step explanation:
V=4
/3πr^3=4/3·π·48^3≈463246.7
ANSWER
The solution is
EXPLANATION
The given equations are:
and
We multiply equation 1 by 3 to get,
We multiply equation 2 also by 2 to get,
We subtract equation 4 from equation 3 to get,
This implies that,
We put this value of y into any of the equations say equation 2
Simplify
Group like terms
Simplify,
Divide both sides by 3 to get,
Therefore the solution is
The correct answer is option D.
Answer:
1) (-3,-2)
2) x=-3
Step-by-step explanation:
1) The vertex of a parabola is the turning point that is the minimum or maximum of the graph, based on the shape of the parabola. In this case, the vertex is the minimum. By looking at the coordinate points, we can tell that the minimum value where the graph changes the direction is at (-3,-2).
2) The line of symmetry is the line on the graph that cuts the shape exactly in half. This means that if you were to fold the graph along this line, the two sides would be identical. All parabolas have a line of symmetry and it always matches the vertex. The equation for the line of symmetry will be x= whatever the x-value of the vertex is. So, for this graph, the line of symmetry is x=-3.
Answer: The answer is 135 murders.
Step-by-step explanation: The report tells us that statistically 67.5% of murders are committed using a firearm. It follows therefore that in a sample of 200 randomly selected murders, one would expect that 67.5% of those would be by a firearm. 
* 200 = 135.
It would certainly be higher that the expected value based on previous data collected but it would not be unusual because one sample may have a higher than "normal" amount of murders by firearm. Statistics aren't going to be exact for every sample.
