Just need to take partial derivatives of the function with respect to x and y then plug in the point coordinates
dT/dx = -38x/(2 + x^2 + y^2)^2dT/dy = -38y/(2 + x^2 + y^2)^2 (only difference is the y in the numerator)
so at point 1,2dT/dx = -38/49 = -0.7755dT/dy = -76/49 = -1.551
The solution of the inequality will be x > 2 and x < -2. And the graph is drawn below.
<h3>What is inequality?</h3>
Inequality is defined as an equation that does not contain an equal sign.
The inequality is given below.
3|x| > 6
By solving the equation, we have
|x| > 2
x > 2
x < -2
Then the graph will be drawn.

The length of the base is 8
area=56
height= 14
A=1/2 bh
56=1/2 b(14)
56=b(14)/2
8=b
