Answer:
The pressure is changing at
Step-by-step explanation:
Suppose we have two quantities, which are connected to each other and both changing with time. A related rate problem is a problem in which we know the rate of change of one of the quantities and want to find the rate of change of the other quantity.
We know that the volume is decreasing at the rate of and we want to find at what rate is the pressure changing.
The equation that model this situation is
Differentiate both sides with respect to time t.
The Product rule tells us how to differentiate expressions that are the product of two other, more basic, expressions:
Apply this rule to our expression we get
Solve for
when P = 23 kg/cm2, V = 35 cm3, and this becomes
The pressure is changing at .
Paralalell means that is has the same slope
y=mx+b
m=slope
y=-1x-2
slope=-1
the equation of a line that passes through the point (x1,y1) and has a slope of m is y-y1=m(x-x1)
given
(2,-2) and slope is -1
y-(-2)=-1(x-2)
y+2=-x+2
minus 2
y=-x
answer is y=-x
B is the correct answer.
8 x 35 = 280
Answer:
Step-by-step explanation:
Given the following system of equations:
In order to solve the system of equations using the Elimination Method, you can follow these steps:
- Multiply the first equation by -6 and the secondd equation by 4.
- Add both equations.
- Solve for "y".
Then:
- Substitute the value of "y" into one of the original equations and solve for "x":
