Answer:
-4
Step-by-step explanation:
distributing gets you to : 8h + 38 = -18 - 6h
then add 6h to 8h and you have 14h + 38 = -18
solve normally & thats how you get your answer
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)
Answer:
Option B is right.
Step-by-step explanation:
We know that a circle is a locus of points keeping equal distance r from a fixed point called centre.
Here we have centre as (2,1)
Hence equation of the circle is given by
To find r, we can use the fact that (5,2) lies on this circle
Hence (5,2) satisfies this equatin.
So
So equation of the circle is
