How do you find derivative of a function with two variables.

Leno4ka [110]

A function z=f(x,y) has two partial derivatives and y. These derivatives correspond to each of the independent variables and can be interpreted as instantaneous rates of change (that is, as slopes of a tangent line). Similarly, ∂z/∂y represents the slope of the tangent line parallel to the y-axis.

When two of the three numbers are added at a time, the possible sums are 32, 39, 23. What is the sum of all three numbers?

arsen [322]

Answer:

47

Step-by-step explanation:

Let a, b, and c be those three numbers.

When two of the three numbers are added at a time, the possible sums are 32, 39, 23. Let

$a+b=32\\ \\a+c=39\\ \\b+c=23$

Add these three equations:

$a+b+a+c+b+c=32+39+23\\ \\2a+2b+2c=94$

Divide this equation by 2:

$a+b+c=47$

The sum of all three numbers is 47.
