Domain:
Range:
=======================================================
Explanation:
domain = set of all possible x inputs
range = set of all possible y outputs
--------------
In this case, the domain is the set of all real numbers because the graph stretches forever to the left and right. There aren't any gaps, holes, jumps, etc to worry about. Any real number works as an input.
We can say x is between and and write
That turns into the interval notation
The curved parenthesis are <u>always</u> used with either infinity because we cannot reach them.
--------------
The range is the same story, but with the y values this time. The graph stretches forever upward and downward due to the arrow.
If it peaked at y = 4, then the range would be , but instead the graph goes beyond y = 4 because of that upward arrow.
Given Information:
Volume of candle = V = 75 in³
Height of candle = h = 6 in
Required Information:
Radius of candle = r = ?
Answer:
Radius of candle = r = 2 in
Step-by-step explanation:
Recall that the volume of a cylindrical shape is given by
Where V is the volume, r is the radius and h is the height
Re-arrange the above equation for radius
Now substitute the given values into the above equation
Rounding to the nearest inch
Therefore, the radius of this candle is 2 inches.
we'd do the same as before on this one as well.
if we take 27.99 to be the 100%, what is 12 off of it in percentage?
Answer:
81
Step-by-step explanation:
Substitute 3 in place of y
7 * 3 * 3 - 16 + 5 * 3 *2 + (16 / 4)
63 - 16 + 30 + 4
