Answer:
(a) 120 square units (underestimate)
(b) 248 square units
Step-by-step explanation:
<u>(a) left sum</u>
See the attachment for a diagram of the areas being summed (in orange). This is the sum of the first 4 table values for f(x), each multiplied by 2 (the width of the rectangle). Quite clearly, the curve is above the rectangle for the entire interval, so the rectangle area underestimates the area under the curve.
left sum = 2(1 + 5 + 17 + 37) = 2(60) = 120 . . . . square units
<u>(b) right sum</u>
The right sum is the sum of the last 4 table values for f(x), each multiplied by 2 (the width of the rectangle). This sum is ...
right sum = 2(5 +17 + 37 +65) = 2(124) = 248 . . . . square units
The transformation <span>using the rule (x, y) → (–x, –y) is a refrection across the line y = x about the origin.
Clearly from the coordinates given, it can be seen that the original triangle is in the first quadrant and the image is in the third quadrant.
Therefore, </span>t<span>he transformation was a 180° rotation about the origin.</span>
Answer:
it should be (based on the instructions we don't have)
Step-by-step explanation:
because the "D" in the parenthesis has 2 negative signs, it inverts itself making it just what D equals, which on the number line is
