Split up the interval [0, 2] into <em>n</em> equally spaced subintervals:
Let's use the right endpoints as our sampling points; they are given by the arithmetic sequence,
where . Each interval has length .
At these sampling points, the function takes on values of
We approximate the integral with the Riemann sum:
Recall that
so that the sum reduces to
Take the limit as <em>n</em> approaches infinity, and the Riemann sum converges to the value of the integral:
Just to check:
Answer:
<h2><em><u>-x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em></h2>
Step-by-step explanation:
<em><u>If</u></em><em><u>,</u></em>
x = -2
<em><u>Then</u></em><em><u>,</u></em>
-x = -(-2)
=> <em><u>-x = 2 (Ans)</u></em>
Answer:
4.9
Explanation:
We are given m = 4 and n = 36 and the expression m + .9.
Replace m with the given value:
4 + .9
Add them together:
4.9
3cmx4models is the beginning to figure out how big the tallest. if you multiply 3 Centimeters (The smallest) by the amount of models (4) you would get 12 so thats you answer 12CM is the height so 4³
Y=12
This is about similarity
12x4=48
5x4=20
So 3x4=12
