A Riemann sum approximates the area of a certain region. Usually it's used in calculus, where you use the Riemann sum to approximate the area a curve instead of using an integral to find the exact value, since that tends to take a lot more time and effort.
<span>8p = 3p + 25
Subtract 3p from both sides: 5p = 25 Divide both sides by 5: '
p = 5</span>
Answer:
28.27530
Step-by-step explanation:
Given the expression 62.834 × 0.45, to solve this expression, first we need to convert it to fraction
62.834 = 62834/1000
0.45 = 45/100
Take the product if the resulting fraction:
62.834 × 0.45 = 62834/1000 × 45/100
= (62834×45)/1000×100
= 2,827,530/100,000
= 28.27530

Explanation:</h2>
Looking at the graph we realize that the y-intercept is given by:
![b=-2](https://tex.z-dn.net/?f=b%3D-2)
The Slope-intercept form of the equation of a line is given by:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
So, our equation becomes:
![y=mx-2](https://tex.z-dn.net/?f=y%3Dmx-2)
So the only option that matches a negative y-intercept is C. Let's see that the slope
. Look at the y-intercept, if you increase x by 3 units, then y increases by 2 units and goes from
to
. In other words:
![Change \ in \ x=\Delta x=3 \\ \\ Change \ in \ y=\Delta y=2 \\ \\ \\ m=\frac{\Delta y}{\Delta x}=\frac{2}{3}](https://tex.z-dn.net/?f=Change%20%5C%20in%20%5C%20x%3D%5CDelta%20x%3D3%20%5C%5C%20%5C%5C%20Change%20%5C%20in%20%5C%20y%3D%5CDelta%20y%3D2%20%5C%5C%20%5C%5C%20%5C%5C%20m%3D%5Cfrac%7B%5CDelta%20y%7D%7B%5CDelta%20x%7D%3D%5Cfrac%7B2%7D%7B3%7D)
