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 = ?
11 L : 20 mL
I believe but that was quick mental math
3x + 8
Because you do not know the number so it is x
Answer: A M (2,-3) and N ( 4,1)
Step-by-step explanation:
(-2, 3) after a 180 degrees rotation the coordinates will be in the fourth quadrant (2,-3) and the y coordinate is always negative in the fourth quadrant.
(-4,1) after a 180 degrees rotation the coordinates will be in the first quadrant (4,1) and all the coordinates will be positive.
3 over 4 is already simplified. 15 over 12 is 5 over 4. If you are having trouble with the concept, www.ducksters.com/kidsmath/fractions_reducing_simplifying.php is a great guide
