Answer:18
Step-by-step explanation:2(18)+3=1/2(18)+30
36+3=9+30
39=39
In order to determine whether a quadrilateral on the coordinate plane is a parallelogram, you must use <span>the slope formulas, the distance formula and the midpoint formula. By using the distance formula, you will find the length of each sides to see if the opposite side is congruent.</span>
Answer:
The number between 1 and 10 is 3
The power of 10 is 4
The number in scientific notation is
-3.46 × 10^4
For the first question, the region is a bit ambiguous.
and
intersect three times, and there are two regions between them. So either you're approximating
or
I'll assume the second case. Split the interval into 4 smaller ones, taking
with respective midpoints of
. The length of each interval is
. Note that I'm also assuming you are supposed to use equally spaced intervals.
Skipping the second one since I already answered it.
For the third, split up the region of integration at some arbitrary constant
between
and
, then differentiate and apply the fundamental theorem of calculus.
Since
, it follows that
is constant.
