A portion of the Quadratic Formula proof is shown. Fill in the missing reason. Statements Reasons ax2 + bx + c = 0 Given ax2 + bx = -c Subtract c from both sides of the equation b LC a Divide both sides of the equation by a a b b с b b (x²+x+ Complete the square and add to both sides 2a a 2a 2a С b? b x2 Square on the right side of the equation a + a 2a 2a 4a? 4ac b2 + a Find a common denominator on the right side of the equation 2a 4a2 + 4a2 0 x2 + x + -4ac 4a Add the fractions together on the right side of the equation a 2a b? - 4ac b 2a 4a Rewrite the perfect square trinomial as a binomial squared on the left side of the equation Take the square root of both sides of the equation Multiply both sides of the equation by 2 Square the left side of the equation .
Answer:
The appropriate answer will be "Y = 157.09 N/m³".
Step-by-step explanation:
The given values are:
Diameter
= 7.5 ft
= 0.3048 meter
Height
= 20ft
= 6.096
Weight density
= 45.93 lb/ft³
= 16.0184634 kg/m³
Acceleration
= 9.807 m/s2
As we know,
The specified density of weight can be expressed as:
⇒ Specific weight = density × acceleration
i.e.,
⇒
On substituting the estimated values in the above expression, we get
⇒
⇒
