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
Divide 25 by 4 and you get 6 with a remainder of 1. That remainder of 1 can go over 4 to create the final answer of 6 and 1/4.
Circle O represents The amount of Degrees,
This can also go for 2 ways! degrees as in angles or Degrees in Temperature! hope rhis helps! If I’m Wrong I sincerely apologize you can always ask questions reach me at 407..463..1322..
Step-by-step explanation: The <em>intersection</em> of two figures can
be defined as the set of points that is contained in both figures.
In this figure, lines <em>h</em> and <em>i</em> intersect at C or we can
say that C is the intersection of lines <em>h </em>and <em>i</em>.
In this figure, C is the intersection of lines <em>h</em> and <em>i</em>
because C is the point contained by both <em>h</em> and <em>i</em>.
All you have to do is substitute x for 3.
You get:
14.50 times 3
14.50 times 3 is 43.50
The answer is $14.50
