Answer:
Width = 8 ft
Length = 53 ft
Height = 9 ft
Step-by-step explanation:
Let width be x
Length will be 8x-11
Height will be x + 1
Volume = width x height x length
=
x * (8x-11) * (x+1) = 3816
(8x^2 - 11x) * (x+1) = 3816
8x^3 + 8x^2 - 11x^2 - 11x = 3816
8x^3 -3x^2 - 11x = 3816
8x^3+64x^2-61x^2-488x +477x-3816= 0
8x^2 (x-8)+61x(x-8)+488(x-8)
(x-8)(8x^2 + 61x + 477) = 0
x-8
8x^2 + 61x + 477 = 0
Solve the equations:
x = 8
Length = 8x -11 = 64-11 = 53
Height = 8+1 = 9
Answer:
72
Step-by-step explanation:
To prove that tan(u - v) does not equal tan u - tan v, we start by assuming values for u and v.
To do this, we assume the following values
![\mathbf{u = 75}](https://tex.z-dn.net/?f=%5Cmathbf%7Bu%20%3D%2075%7D)
![\mathbf{v = 45}](https://tex.z-dn.net/?f=%5Cmathbf%7Bv%20%3D%2045%7D)
So, we have:
![\mathbf{tan(u - v) \ne tan(u) - tan(v)}](https://tex.z-dn.net/?f=%5Cmathbf%7Btan%28u%20-%20v%29%20%5Cne%20tan%28u%29%20-%20tan%28v%29%7D)
Substitute the assumed values for u and v
![\mathbf{tan(75 - 45) \ne tan(75) - tan(45)}](https://tex.z-dn.net/?f=%5Cmathbf%7Btan%2875%20-%2045%29%20%5Cne%20tan%2875%29%20-%20tan%2845%29%7D)
Subtract 45 from 75
![\mathbf{tan(30) \ne tan(75) - tan(45)}](https://tex.z-dn.net/?f=%5Cmathbf%7Btan%2830%29%20%5Cne%20tan%2875%29%20-%20tan%2845%29%7D)
Using a calculator, calculate the values of tan(30), tan(45) and tan(75)
So, we have:
![\mathbf{0.5774 \ne 3.7321 - 1}](https://tex.z-dn.net/?f=%5Cmathbf%7B0.5774%20%5Cne%203.7321%20-%201%7D)
Subtract 1 from 3.7321
![\mathbf{0.5774 \ne 2.7321}](https://tex.z-dn.net/?f=%5Cmathbf%7B0.5774%20%5Cne%202.7321%7D)
Notice that the expression on the left-hand side and the expression on the right-hand side are not equal.
Hence,
is true
