Step-by-step explanation:
The given equation is
![- \frac{1}{2} {x}^{2} + 2 = 2 {x}^{2} - 8](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%202%20%3D%202%20%7Bx%7D%5E%7B2%7D%20%20-%208)
The graph of the left hand side of this equation is
![y = - \frac{1}{2}{x}^{2} + 2](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%7Bx%7D%5E%7B2%7D%20%20%2B%202)
This quadratic graph has its vertex at (0,2) and turns upside down.
The right hand side of the equation is
![y = 2 {x}^{2} - 8](https://tex.z-dn.net/?f=y%20%3D%202%20%7Bx%7D%5E%7B2%7D%20%20-%208)
This quadratic graph opens upwards and has its vertex at (0,-8).
The two graphs intersects at two points , which are (-2,0) and (2,0).
Answer:
The correct answer is first option. 270 m³
Step-by-step explanation:
Formula:
Volume of prism = Base area * Height
Area of triangle = bh/2 where b - base and h - height
From the figure we can see that height of prism = 36 m
Base is a right angled triangle with base 5 m and height = 3 m
<u>To find the Base area</u>
Area of triangle = bh/2 = (3 * 5)/2 = 15/2 = 7.5
<u>To find the volume of prism</u>
Volume = Base area * height = 7.5 * 36 = 270 m³
Therefore the correct answer is first option . 270 m³
