It is probably random, since they are asking random users to identify new features they would use. :)
Answer:
2km
Step-by-step explanation:
8km/h×15minutes÷60minutes=2km
Step-by-step explanation:
3x + 2y = 6
-3x -3x
2y = 6 - 3x
/2 /2 /2
y = 3 - 1.5x
If you'd graph this function, you'd see that it's positive on [-1.5,0], and that it's possible to inscribe 3 rectangles on the intervals [-1.5,-1), (-1,-0.5), (-0.5, 1].
The width of each rect. is 1/2.
The heights of the 3 inscribed rect. are {-2.25+6, -1+6, -.25+6} = {3.75,5,5.75}.
The areas of these 3 inscribed rect. are (1/2)*{3.75,5,5.75}, which come out to:
{1.875, 2.5, 2.875}
Add these three areas together; you sum will represent the approx. area under the given curve on the given interval: 1.875+2.5+2.875 = ?
