Answer:
Write the problem as a mathematical expression.
y=−x²+18x−72
Rewrite the equation in vertex form.
y=−(x−9)²+9
Use the vertex form, y=a(x−h)2+k , to determine the values of a, h, and k.
a=−1
h=9
k=9
Find the vertex (h,k).
(9,9)

Answer:
5.18 pounds per square inch
Complete question:
If the pressure is 6 pounds per square inch when the temperature is 440° F,find the pressure exerted when the temperature of the gas is 380°F.
Step-by-step explanation:
According to the Gay Lussac's Law:
where, P and T are the pressure and temperature of an enclosed ideal gas.
Given:
Initial pressure = 6 pounds per square inch
Initial Temperature =440° F
Final Temperature =380° F
Final Pressure =?
Substituting all values in the formula
=
= 5.18pounds per square inch
