Step-by-step explanation:
Maximum rate of change of a function f(x,y) is expressed as the gradient of such function at the given point. Gradient of a function is expressed as;
∇f(x,y) =
Given f(x,y)=ln(x²+y²) at the point (-2, 2)
<em>Hence the maximum rate of range of the function at the point (-2,2) is </em><em></em>
To get the direction, we willl use the formula;
From the vector gotten, x = -1/2 and y = 1/2
<em>Since tan theta is negative in the second quadrant, the direction in which it occurs will be 180-45 = 135°</em>
Answer:
(0,-5)
(4,-2)
(-16,-17)
Step-by-step explanation:
Any (x,y) point that satisfies the equation is a solution. First simplify the equation.
3x - 4y - 8 = 12
3x - 4y = 20
Substitute x = 0 and y = -5.
The equation becomes 3(0) -4(-5) = 20.
0 + 20 = 20
This is a solution.
The following points also work and are solutions.
(4, -2) and (-16,-17)
