Answer:
The coordinates are x=2 and y=16, or (2, 16)
Step-by-step explanation: The definition of the vertex of a parabola(the shown graph) is the highest or lowest point on the graph, depending which way the graph opens. When a graph opens upwards, towards positive y, the vertex is the lowest point. On the contrary, when the graph opens downwards, like this graph, the vertex is the highest point. On the graph, you can see clearly that the highest point on the graph has an x-value of 2 and a y-value of 16, making the vertex (2, 16)
Using a graphing tool
Let's graph each of the cases to determine the solution of the problem
<u>case A)</u>
see the attached figure N
The range is the interval--------> (0,∞)
therefore
the function is not the solution
<u>case B)</u>
see the attached figure N
The range is the interval--------> (0,∞)
therefore
the function is not the solution
<u>case C)</u>
see the attached figure N
The range is the interval--------> (-∞,3)
therefore
the function is the solution
<u>case D)</u>
see the attached figure N
The range is the interval--------> (-3,∞)
therefore
the function is not the solution
<u>the answer is</u>
180 degrees in a triangle therefore you will subtract 54 and 79 from 180 which then gives you the answer --47--
do you understand how to do it now ?
Use the formula above to find the surface area of a cylinder.
For the given cylinder the given data is the height (6mi) and diameter (16mi), use the diameter to find the radius:
Surface area:
Then, the surface area of the given cylinder is: 224π square miles
Answer: A. (72π - 144) mm²
