Answer:
Katie made a mistake. P = (nRT)/P is the correct equation, not V = PnRT
Step-by-step explanation:
The equation for the ideal gas law is PV = nRT, where P is pressure, V is volume, n is the moles of gas, R is the gas constant, and T is the temperature, in Kelvin.
Solving for V:
PV = nRT
V = (nRT)/P
Katie did not solve the equation corretly. To move V from the left to the right side of the equation, she needed to divide both sides by P:
PV = nRT
PV/V = (nRT)/P
P = (nRT)/P is the correct equation
I believe the equation is f(x) = 2^x -3
Answer:
254.34 mm²
Step-by-step explanation:
Diameter (d) = 18 mm
Radius (r) = d/2 = 18/2 = 9 mm
π = 3.14
Area of the circle
= πr²
= (3.14)(9)²
= 3.14 × 81
= 254.34 mm²

Answer:
The coordinates of A could be anything in the form of (x, y, z) if you have a third axis. First you count where A is on the x-axis then the y-axis and if you have a 3-dimensional graph then the z-axis.
