Answer:
The input is zero, the output is -1
Step-by-step explanation:
We want to know the y value when the x value is zero
When x =0, y = -1
The input is zero, the output is -1
Answer:
261.67 cubic feet
Use the Cone Volume formula V=πr^2 h/3
Volume = (l * w * h) or (11 * 3 * x) which will equal surface area. Volume is 33x for now
Surface Area = 2 (x * 11) + 2 (x * 3) + 2 (11 * 3)
Set Volume equal to surface area. I simplified SA already.
33x = 22x + 6x + 66
33x - 28x = 66
5x = 66
x = 66/5 or 13.2
Answer:
14.25 units
Step-by-step explanation:
Area of a square= ![l*b= (x-3)(x-3)=x^{2}-3x-3x+9=x^{2}-6x+9](https://tex.z-dn.net/?f=l%2Ab%3D%20%28x-3%29%28x-3%29%3Dx%5E%7B2%7D-3x-3x%2B9%3Dx%5E%7B2%7D-6x%2B9)
![x^{2}-6x+9=126.5625](https://tex.z-dn.net/?f=x%5E%7B2%7D-6x%2B9%3D126.5625)
![x^{2}-6x-117.5625](https://tex.z-dn.net/?f=x%5E%7B2%7D-6x-117.5625)
Solving the equation using quadratic equation then as attached
x=14.25 units
To prove
x-3=14.25-3= 11.25 units
area=11.25*11.25=126.5625 sq units
12x2= $24
24+28+45= $97
So $97 is 100%
So 100%-30% =70% (30% off)
(note: 70% = 70/100 = 0.7)
97 x 0.7 = $67.90
