Answer:
opt 4
Step-by-step explanation:
when x=0, 0+3y= -3, so y=-1 (0,-1) is solution
when x=3 , 21+3y=-3, 3y= -3-21= -24
y= -8 (3,-8) is also solution
The percentage this empty space is of the entire volume is 26.12 % when rounded to the nearest tenth.
We have given that the shape of a
cylinder Container A has a diameter of 30 feet and a height of 18 feet.
diameter =30 feet and height =18 feet
Therefore
![radius=\frac{d}{2} \\\\radius=\frac{30}{2} \ \\\\radius=15](https://tex.z-dn.net/?f=radius%3D%5Cfrac%7Bd%7D%7B2%7D%20%5C%5C%5C%5Cradius%3D%5Cfrac%7B30%7D%7B2%7D%20%5C%20%5C%5C%5C%5Cradius%3D15)
What is the formula for volume of cylinder ?
![volume =\pi r^2h](https://tex.z-dn.net/?f=volume%20%3D%5Cpi%20r%5E2h)
For cylinder A,
![volume =\pi r^2h](https://tex.z-dn.net/?f=volume%20%3D%5Cpi%20r%5E2h)
![volume =\pi (15)^218\\ \\V=12723.45 ft^{3}](https://tex.z-dn.net/?f=volume%20%3D%5Cpi%20%2815%29%5E218%5C%5C%20%5C%5CV%3D12723.45%20ft%5E%7B3%7D)
Similarly for cylinder B,
h=19
radius
![\frac{26}{2} =13feet](https://tex.z-dn.net/?f=%5Cfrac%7B26%7D%7B2%7D%20%3D13feet)
volume of cylinder B
![volume =\pi r^2h\\\\volume =\pi (13)^2(19)\\\\volume =10087.65 feet^3](https://tex.z-dn.net/?f=volume%20%3D%5Cpi%20r%5E2h%5C%5C%5C%5Cvolume%20%3D%5Cpi%20%2813%29%5E2%2819%29%5C%5C%5C%5Cvolume%20%3D10087.65%20feet%5E3)
After pumping all of Cylinder A into Cylinder B there will remain empty space in B
![12723.45-10087.65=2635.8 feet^3](https://tex.z-dn.net/?f=12723.45-10087.65%3D2635.8%20feet%5E3)
The percentage this empty space is,
of the entire volume is
![\frac{2635.8}{10087.65} =0.261289](https://tex.z-dn.net/?f=%5Cfrac%7B2635.8%7D%7B10087.65%7D%20%3D0.261289)
which is 26.12 % when rounded to the nearest tenth.
Therefore,
The percentage this empty space is of the entire volume is 26.12 % when rounded to the nearest tenth.

Answer:
4
Step-by-step explanation:
complex roots always occur in pairs.
so roots are -3+2i,-3-2i ,-2,-2
number of roots=4
