Step-by-step explanation:
Given
Required
Write as an absolute value inequality
The absolute value inequality can be derived using
First Step: Get the middle of the interval
Next: Get the Length of the interval
Substitute values for Mid and Length in
Hence:
<em>The absolute inequality is </em><em></em>
can also be written as 2i
where i = √-1
Rationalizing denominator,
Answer:
2 places after the decimal point.
Step-by-step explanation:
Check the picture below.
now, we know the directrix is at y = 1, and the focus point is at 1,3, well, notice the picture, the distance between those fellows is just 2 units.
the vertex is half-way between those fellows, therefore, the vertex will be at 1,2.
the distance "p", from the vertex to either the directrix or focus, is really just 1 unit. Since the focus point is above the directrix, is a vertical parabola, and it opens upwards, like in the picture, and since it opens up, the "p" value is positive, or +1.
