Answer:
59
Step-by-step explanation:
Answer:
The pressure is 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
In this problem we have

where
V is the volume of a gas at a constant temperature
P is the pressure
we have
For
,
step 1
Find the value of k
substitute the values of V and P


The equation is equal to 
step 2
Find the pressure when the volume is 125 cubic inches
For 
substitute in the equation and solve for P


Answer:
The sign is negative
Step-by-step explanation:
Given



Required
Determine the sign
The expression can be split into 3 factors

If x > 0 then x is positive and If y < 0 then y is negative
So, the expression becomes:

<em />
Leave only signs


So, we have:



So, we have:

<em>Hence, the sign of the expression is negative</em>
<em></em>
Take for instance;


The expression would be:
-- negative
Answer:
3
Step-by-step explanation:
mark brainliest

has critical points where the derivative is 0:

The second derivative is

and
, which indicates a local minimum at
with a value of
.
At the endpoints of [-2, 2], we have
and
, so that
has an absolute minimum of
and an absolute maximum of
on [-2, 2].
So we have
