Answer:
The value of rate of decrease of volume = - 3600 
Step-by-step explanation:
According to Boyle's law P V = C ------- (1)
Pressure ( P ) = 100 k pa = 10 
Volume ( V ) = 900 
Put these values in equation ( 1 ) we get,
⇒ C = 10 × 900 = 9000 N-cm = 90 N-m
Differentiate Equation ( 1 ) with respect to time we get,
⇒ V
+ P
= 0
⇒ V
= - P 
⇒
= -
---------- (2)
This equation gives the rate of decrease of volume.
Given that Rate of increase of pressure =
= 40 
C = 90 N-m
P =
pa = 10 
V = 900
Put all the above values in equation 2 we get,
⇒
= -
× 40
⇒
= - 3600 
This is the value of rate of decrease of volume.
Do the opposite to the x..if it was -2x you plus that
Step-by-step explanation:
1. Use the Pythagorean theorem to solve for side KM:
- 16^2+KM^2=34^2
- 256+KM^2=1156
- KM^2=900
- KM=30
2. Cosine is adjacent over hypotenuse, so cosine of M would be KM/34, or 30/34
3. Tangent is opposite over adjacent, so tangent of L will be KM/16, or 30/16
4. Sine is opposite over hypotenuse, so sine of M will be 16/34
5. KM=30, solved for in step 1.
hope this helps!!
