Answer:
<h3>
C) - x - 9y.</h3>
Step-by-step explanation:
Given : -(3x+y)+2(x-4y).
To find : which expression is the simplest form .
Solution : We have given
-(3x+y)+2(x-4y).
Remove parenthesis
-3x -y + 2x -8y .
Combine like terms
-3x + 2x -y - 8y .
-x -9y.
<h3>
Therefore, C) - x - 9y.</h3>
ANSWER
EXPLANATION
The cotangent function that is fully transformed is of the form
where 'a' is the amplitude.
is the period.
This implies that b=1
The phase shift is
Substitute b=1 to get;
and d=2 is the vertical shift.
We choose a=1 to get the required function as
Answer:
162
Step-by-step explanation:
V = L X W X H
V = 6 X 3 X 9
6 times 3 is 18
V = 18 X *
18 times 9 is 162
V = 162
hope this helped :D
Answer:
82.79MPa
Step-by-step explanation:
Minimum yield strength for AISI 1040 cold drawn steel as obtained from literature, Sᵧ = 490 MPa
Given, outer radius, r₀ = 25mm = 0.025m, thickness = 6mm = 0.006m, internal radius, rᵢ = 19mm = 0.019m,
Largest allowable stress = 0.8(-490) = -392 MPa (minus sign because of compressive nature of the stress)
The tangential stress, σₜ = - ((r₀²p₀)/(r₀² - rᵢ²))(1 + (rᵢ²/r²))
But the maximum tangential stress will occur on the internal diameter of the tube, where r = rᵢ
σₜₘₐₓ = -2(r₀²p₀)/(r₀² - rᵢ²)
p₀ = - σₜₘₐₓ(r₀² - rᵢ²)/2(r₀²) = -392(0.025² - 0.019²)/2(0.025²) = 82.79 MPa.
Hope this helps!!
