Answer: 5.18 pound per square inch
Step-by-step explanation:
According to pressure law, the pressure of a gas is directly proportional to the temperature
P1/T1 = P2/T2
where P1 is the initial pressure = 6 pounds
T1 is the initial to temperatures = 440°F
P2 is the final pressure = Z
T2 is the final temperature = 380°F
Thus, let final pressure be Z
P1/T1 = P2/T2
6/440 = Z/380
0.0136 = Z/380
Make Z the subject formula
Z = 380 x 0.0136
Z = 5.18 pound per square inch
Thus, the final pressure at 380°F is 5.18 psi (pound per square inch)
You wish to evaluate y at t= 2.0 and t=2.5. the average velocity over this interval will be 1/(0.5)*(v(2.5)-v(2.0))
Answer:
No (1,8) is not a solution to 19x+3y=2.
However, (1,8) is a solution to 3x+y=11.
Step-by-step explanation:
(1,8)
The one represents the x shown in each equation, the eight represents the y.
Substitute the one in for the x and the eight in for the y.
19x+3y=2
19(1)+3(8)
3x+y=11
3(1)+(8)
Next, solve the equation.
19(1)+3(8) = 43
3(1)+(8) = 11
As you can see, 43 does not equal 2.
But, 11 does equal 11.
Answer:
Step-by-step explanation:
In this case the solution of the integral is
[R^{2} - 0]h = \pi R^{2}h](https://tex.z-dn.net/?f=%5Cint%5Climits%5E%7B2%5Cpi%7D%20_0%20%7B%7D%20%5C%2C%20d%5Cphi%20%5Cint%5Climits%5ER_0%20%7B%5Crho%7Dh%20%5C%2C%20d%5Crho%20%3D%20%5B2%5Cpi%20-%200%5D%28%5Cfrac%7B1%7D%7B2%7D%20%29%5BR%5E%7B2%7D%20-%200%5Dh%20%3D%20%5Cpi%20R%5E%7B2%7Dh)
because h is a constant, and where the expression
was used.
I hope this is usefull for you
