Answer:

x=0

Step-by-step explanation:

in the quadratic formula to only have one solution

b^{2} -4ac=0 for ax^2+bx+c=0

so we have

ax^2+b=c

ax^2+(b-c)=0

if we insert in the formula we have

0^2-4(a)(b-c)=0\\\\-4ab+4ac=0\\\\4ac=4ab\\\\\frac{4ac}{4a} = \frac{4ab}{4a}\\\\c=b

ax^2+b=c\\\\ax^2=b-b\\\\ax^2=0 since a≠0

\frac{ax^2}{a}=\frac{0}{a}  \\\\x^2=0\\\\x=0

Please Help!! A septic tank has the shape shown in the figure. How many gallons does it hold? (1 cu ft = 7.48 gallons.) (Round t
Hoochie [10]

The overall volume is the sum of the volume of a cylinder of height 5'9" and diameter 3'6", and a sphere of diameter 3'6" (two hemispheres = full sphere).

Volume of the cylinder = (area of the base) x (height) = pi * (diameter/2)^2 * 5.75ft = 3.1415 * (3.5ft/2)^2 * 5.75 ft = 55.32 ft^3

Volume of the sphere = 4/3 * pi * (3.5ft)^3 / 8 = 22.45 ft^3

Total volume = (Volume of cylinder) + (Volume of sphere) = (55.32 + 22.45) ft^3 = 77.77 ft^3
