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.

Answer:
C
Step-by-step explanation:
The perimeter of any shape is the distance around the edge of the shape. It is found by adding the side lengths of each side together.
Add each side length listed for the triangle part.
1 step (B): raise both sides of the equation to the power of 2.
.
2 step (A): simplify to obtain the final radical term on one side of the equation.
.
3 step (F): raise both sides of the equation to the power of 2 again.
.
4 step (E): simplify to get a quadratic equation.
.
5 step (D): use the quadratic formula to find the values of x.
.
6 step (C): apply the zero product rule.
.
Additional 7 step: check these solutions, substituting into the initial equation.
