1. The graph is a parabola.
2. The parabola opens up, because there's no negative number in front of .
3. The vertext is (5,-1), because of the vertex form.
This means that that -1 will be the least y-value used on the graph and the garph will open up from there.
The range is (-1, infinity) or { y | y > -1 }.
Answer:
The maximum error in the calculated area of the rectangle is
Step-by-step explanation:
The area of a rectangle with length and width
is
so the differential of <em>A</em> is
so
We know that each error is at most 0.1 cm, we have ,
. To find the maximum error in the calculated area of the rectangle we take
,
and
,
. This gives
Thus the maximum error in the calculated area of the rectangle is
