Technically no. It extends forever in the X and Y axis, but does not have a Z axis.
Answer:
Opt A and D
Step-by-step explanation:
65% is 100 based number, this means that 65% is the same as 65/100, or 0,65.
65% of 20 is obtained performing the following operation:
0,65 * 20
or
65*20/100
Any of them
Answer:
H.A.=4
Step-by-step explanation:
If the bottom equation is factored, you get (x+1)(x-4)
If the V.A. is -1 ( gotten by putting [x+1] equal to zero I'm guessing) then the H.A. can be gotten by putting (x-4) equal to zero.
Also, I graphed it.
Answer and explanation:
Given : The position of an object moving along an x axis is given by
where x is in meters and t in seconds.
To find : The position of the object at the following values of t :
a) At t= 1 s
![x(t)=3.24t-4.20t^2+1.07t^3](https://tex.z-dn.net/?f=x%28t%29%3D3.24t-4.20t%5E2%2B1.07t%5E3)
![x(1)=3.24(1)-4.20(1)^2+1.07(1)^3](https://tex.z-dn.net/?f=x%281%29%3D3.24%281%29-4.20%281%29%5E2%2B1.07%281%29%5E3)

![x(1)=0.11](https://tex.z-dn.net/?f=x%281%29%3D0.11)
b) At t= 2 s
![x(t)=3.24t-4.20t^2+1.07t^3](https://tex.z-dn.net/?f=x%28t%29%3D3.24t-4.20t%5E2%2B1.07t%5E3)
![x(2)=3.24(2)-4.20(2)^2+1.07(2)^3](https://tex.z-dn.net/?f=x%282%29%3D3.24%282%29-4.20%282%29%5E2%2B1.07%282%29%5E3)
![x(2)=6.48-16.8+8.56](https://tex.z-dn.net/?f=x%282%29%3D6.48-16.8%2B8.56)
![x(2)=-1.76](https://tex.z-dn.net/?f=x%282%29%3D-1.76)
c) At t= 3 s
![x(t)=3.24t-4.20t^2+1.07t^3](https://tex.z-dn.net/?f=x%28t%29%3D3.24t-4.20t%5E2%2B1.07t%5E3)

![x(3)=9.72-37.8+28.89](https://tex.z-dn.net/?f=x%283%29%3D9.72-37.8%2B28.89)
![x(3)=0.81](https://tex.z-dn.net/?f=x%283%29%3D0.81)
d) At t= 4 s
![x(t)=3.24t-4.20t^2+1.07t^3](https://tex.z-dn.net/?f=x%28t%29%3D3.24t-4.20t%5E2%2B1.07t%5E3)

![x(4)=14.24](https://tex.z-dn.net/?f=x%284%29%3D14.24)
(e) What is the object's displacement between t = 0 and t = 4 s?
At t=0, x(0)=0
At t=4, x(4)=14.24
The displacement is given by,
![\triangle x=x(4)-x(0)](https://tex.z-dn.net/?f=%5Ctriangle%20x%3Dx%284%29-x%280%29)
![\triangle x=14.24-0](https://tex.z-dn.net/?f=%5Ctriangle%20x%3D14.24-0)
![\triangle x=14.24](https://tex.z-dn.net/?f=%5Ctriangle%20x%3D14.24)
(f) What is its average velocity from t = 2 s to t = 4 s?
At t=2, x(2)=-1.76
At t=4, x(4)=14.24
The average velocity is given by,
![\triangle x=x(4)-x(2)](https://tex.z-dn.net/?f=%5Ctriangle%20x%3Dx%284%29-x%282%29)
![\triangle x=14.24-(-1.76)](https://tex.z-dn.net/?f=%5Ctriangle%20x%3D14.24-%28-1.76%29)
![\triangle x=14.24+1.76](https://tex.z-dn.net/?f=%5Ctriangle%20x%3D14.24%2B1.76)
