No.
Tom forgot about the area of the top/roof, the floor and roof are different dimensions/areas, making his method incomplete.
He needs to find area of Roof, Floor then times height.
Please, for clarity, use " ^ " to denote exponentiation:
Correct format: x^4*y*(4) = y*x^2*(13)
This is an educated guess regarding what you meant to share. Please err on the side of using more parentheses ( ) to show which math operations are to be done first.
Your (x+y)2, better written as (x+y)^2, equals x^2 + 2xy + y^2, when expanded.
The question here is whether you can find this x^2 + 2xy + y^2 in your
"X4y(4) = yx2(13)"
Please lend a hand here. If at all possible obtain an image of the original version of this problem and share it. That's the only way to ensure that your helpers won't have to guess what the problem actually looks like.
Answer:
dC = 2.44
Relative error = 19%
Step-by-step explanation:
![C = 35.74 + 0.6215*T - 35.75*v^(0.16) + 0.4275*T*v^(0.16)](https://tex.z-dn.net/?f=C%20%3D%2035.74%20%2B%200.6215%2AT%20-%2035.75%2Av%5E%280.16%29%20%2B%200.4275%2AT%2Av%5E%280.16%29)
Δv = 3 ; ΔT = 1 , v = 23, T = 8
Use differential Calculus
![dC = Cv.dv + Ct.dt](https://tex.z-dn.net/?f=dC%20%3D%20Cv.dv%20%2B%20Ct.dt)
![Cv = dC/dv = -5.72*v^(-0.84) + 0.0684*T*v^(-0.84)\\Ct = dC/dT = 0.6215 + 0.4275*v^(0.16)\\dC = modulus (Cv.dv) + modulus (CT.dT)\\dC = (-5.72*v^(-0.84) + 0.0684*T*v^(-0.84))* 3 + (0.6215 + 0.4275*v^(0.16))*1\\dC = 2.44](https://tex.z-dn.net/?f=Cv%20%3D%20dC%2Fdv%20%3D%20-5.72%2Av%5E%28-0.84%29%20%2B%200.0684%2AT%2Av%5E%28-0.84%29%5C%5CCt%20%3D%20dC%2FdT%20%3D%200.6215%20%2B%200.4275%2Av%5E%280.16%29%5C%5CdC%20%3D%20modulus%20%28Cv.dv%29%20%2B%20modulus%20%28CT.dT%29%5C%5CdC%20%3D%20%28-5.72%2Av%5E%28-0.84%29%20%2B%200.0684%2AT%2Av%5E%28-0.84%29%29%2A%203%20%2B%20%280.6215%20%2B%200.4275%2Av%5E%280.16%29%29%2A1%5C%5C%3Cstrong%3EdC%20%3D%202.44%3C%2Fstrong%3E)
Relative Error
dC / C @(T = 8, v=23) * 100 = 19 %
Yes. Both are at a right angle and both have the little tick on line AB and XY, so they must be congruent.
