Answer:
8 11/100
Step-by-step explanation:
8.11 is the same thing as 8 whole numbers and since the .11 is in the hundreths place, it becomes 11/100.
Let P be the plane that intersects
- x-axis at point (-5,0,0);
- y-axis at point (0,-2,0);
- z-axis at point (0,0,5).
Write the equation of the plane P:
![\left|\begin{array}{ccc}x-(-5)&y-0&z-0\\0-(-5)&-2-0&0-0\\0-(-5)&0-0&5-0\end{array}\right|=0\Rightarrow \left|\begin{array}{ccc}x+5&y&z\\5&-2&0\\5&0&5\end{array}\right|=0.](https://tex.z-dn.net/?f=%5Cleft%7C%5Cbegin%7Barray%7D%7Bccc%7Dx-%28-5%29%26y-0%26z-0%5C%5C0-%28-5%29%26-2-0%260-0%5C%5C0-%28-5%29%260-0%265-0%5Cend%7Barray%7D%5Cright%7C%3D0%5CRightarrow%20%5Cleft%7C%5Cbegin%7Barray%7D%7Bccc%7Dx%2B5%26y%26z%5C%5C5%26-2%260%5C%5C5%260%265%5Cend%7Barray%7D%5Cright%7C%3D0.)
Then
![-10(x+5)+10z-25y=0,\\ \\2(x+5)-2z+5y=0,\\ \\2x+5y-2z=-10.](https://tex.z-dn.net/?f=-10%28x%2B5%29%2B10z-25y%3D0%2C%5C%5C%20%5C%5C2%28x%2B5%29-2z%2B5y%3D0%2C%5C%5C%20%5C%5C2x%2B5y-2z%3D-10.)
The coefficients at variables x, y and z are the coordinates of perpendicular vector to the plane. Thus
![\vec{v}=(2,5,-2)\perp P.](https://tex.z-dn.net/?f=%5Cvec%7Bv%7D%3D%282%2C5%2C-2%29%5Cperp%20P.)
Answer: ![\vec{v}=(2,5,-2).](https://tex.z-dn.net/?f=%5Cvec%7Bv%7D%3D%282%2C5%2C-2%29.)
