They are all even numbers
(You copied 'upper left' twice, and you left out 'lower right'.
But we know what you mean.)
If those are the corners of the wall, then they're ALL in the plane of
the wall (coplanar with it).
Answer:- The pressure 'p' will be infinity at volume 'V'=0.
Explanation:-
The given equation :- 
where p is a rational function dependent on V.
A rational function is undefined for denominator = 0.
In the given function V is the denominator , if V=0 then the function will be undefined.
⇒ p will approach to zero at V=0.
For assistance see the attachment , the graph of the given function represented by vertical assymptote which approaches to 0 but never touches it..
For part A, if P is the center of that triangle, then PR and PT have the same length; therefore, triangle RPT is isosceles. For part B, by the definition of an incenter...if P is an incenter, then it is the place where all the angle bisectors meet. Therefore, angles SRP and PRT are congruent, as are angles STP and PTR. Since the vertex angle measures 64, then each of the base angles by the isosceles triangle theorem measure 58. Half of 58 makes the base angles within the smaller triangle measure 29. And if both of those measure 29, by the triangle angle-sum theorem, 180-29-29 = 122 And that's the measure of angle RPT. Eek.
Answer:
Let's see what you can do with parallel and perpendicular. In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other
