Answer:x³-8x²-x+8
Step-by-step explanation:
x are equal to -1,1,8 respectively
to form the polynomials just simply use this method put (x-)to the given numbers that are zeros of the polynomials
(x-(-))(x-1)(x-8)
(x+1)(x-1)(x-8) →(x+1)(x-1) are diff. of two squares (x²-1)
(x²-1)(x-8)
x²(x-8)-1(x-8)
p(x)=x³-8x²-x+8
The 3rd answer, when m is next to a number it means “per” for something like per second or (in this case) per minute, etc...
Answer:
The volume of the cone is ![942cm^3](https://tex.z-dn.net/?f=942cm%5E3)
Step-by-step explanation:
The given cone has a radius of 10 cm and and height of 9 cm.
The volume of a cone is given by:
![V=\frac{\pi r^2h}{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B%5Cpi%20r%5E2h%7D%7B3%7D)
We substitute r=10 and h=9 ,
to obtain:
![V=\frac{3.14*10^2*9}{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B3.14%2A10%5E2%2A9%7D%7B3%7D)
Simplify exponents to get:
![V=\frac{3.14*100*9}{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B3.14%2A100%2A9%7D%7B3%7D)
Simplify:
![V=314*3\\V=942cm^3](https://tex.z-dn.net/?f=V%3D314%2A3%5C%5CV%3D942cm%5E3)
Therefore the volume of the cone is ![942cm^3](https://tex.z-dn.net/?f=942cm%5E3)
It will change from having a value of 7,000 to having a value of 70
