A certain forest covers an area of 2100 km^2. Suppose that each year this area decreases by 5.25%. What will the area be after 6
1 answer:
Answer:
The area after 6 years is
<em></em>
Step-by-step explanation:
Given
--- Initial Value
--- Rate
Required
Determine the area after 6 years
Because the area reduces,, the following formula will be used to solve the question.
Here
So, we have:
Convert percentage to decimal
-- approximated
<em>The area after 6 years is </em><em></em>

So hmmm check the picture below
so... the vertex is "p" distance from the focus and the directrix, thus, the vertex is really half-way between both
in this case, 2 units up from the focus or 2 units down from the directrix, and thus it lands at 3,3
now, the "p" distance is 2, however, the directrix is up, the focus point is below it, the parabola opens towards the focus point, thus, the parabola is opening downwards, and the squared variable is the "x"
because the parabola opens downwards, "p" is negative, and thus, -2
now, let's plug all those fellows in then
