1. You con solve the quadratic equation x^2+20x+100=50<span> by following the proccedure below:
2. Pass the number 50 from the right member to the left member. Then you obtain:
x^2+20x+100-50=0
</span><span> x^2+20x+50=0
</span><span>
3. Then, you must apply the quadratic equation, which is:
x=(-b±√(b^2-4ac))/2a
</span><span>x^2+20x+50=0
</span><span>
a=1
b=20
c=50
4. Therefore, when you substitute the values into the quadratic equation and simplify ir, you obtain that the result is:
-10</span>±5√2 (It is the last option).
Answer:
x^4 - 2x^3 - 29x^2 - 42x
Step-by-step explanation:
Equal all the zeros to x then move them over.
x=7,x=-3,x=0,x=-2
x-7,x+3,x+0,x+2
Then multiply each factor
(x-7)(x+3)(x)(x+2)
x^4 - 2x^3 - 29x^2 - 42x
The volume of each container is: 25,133 ![cm^{3}](https://tex.z-dn.net/?f=cm%5E%7B3%7D)
Given:
height of container (h) = 80 cm
diameter of container (d) = 20 cm
radius = half of diameter =
of ![20 = 10 cm](https://tex.z-dn.net/?f=20%20%3D%2010%20cm)
Recall:
Volume of a cylinder = ![\pi r^{2} h](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D%20h)
<em>Substitute the values into the formula:</em>
![Volume = \pi \times 10^{2} \times 80 = 25132.74123](https://tex.z-dn.net/?f=Volume%20%3D%20%5Cpi%20%5Ctimes%2010%5E%7B2%7D%20%5Ctimes%2080%20%3D%2025132.74123)
Therefore, volume of each cylinder is approximately 25,133 ![cm^{3}](https://tex.z-dn.net/?f=cm%5E%7B3%7D)

Paralell has same slope
y=mx+b
m=slope
y=1/2x+b
find b
(x,y)
(4,0)
x=4
y=0
0=1/2(4)+b
0=2+b
minus 2 both sides
-2=b
the equaiton is
y=1/2x-2
or
x-2y=4
