Answer:
Step-by-step explanation:
looking at the graph,
when x = 3, y = -10
-10 = 2(3)^2 + 3b + 8
-10 = 18 + 3b + 8
-10 = 26 + 3b
3b = -36
b = -36/3
b = -12
Answer:
The final integration in the given limits will be 89.876
Given:
The graph of line.
To find:
The gradient of the line using rise/run method.
Solution:
We know that the gradient of a line is also known as slope.
![Slope=\dfrac{Rise}{Run}](https://tex.z-dn.net/?f=Slope%3D%5Cdfrac%7BRise%7D%7BRun%7D)
Consider the two intercepts, then rise is distance between origin and y-intercept and run is the distance between origin and the x-intercept. But rise must be negative because the value of y decreased from 3 to 0.
![Rise=-3](https://tex.z-dn.net/?f=Rise%3D-3)
![Run=2](https://tex.z-dn.net/?f=Run%3D2)
Now,
![Slope=\dfrac{Rise}{Run}](https://tex.z-dn.net/?f=Slope%3D%5Cdfrac%7BRise%7D%7BRun%7D)
![Slope=\dfrac{-3}{2}](https://tex.z-dn.net/?f=Slope%3D%5Cdfrac%7B-3%7D%7B2%7D)
The gradient of the line is
.
Therefore, the correct option is C.
