Find the partial derivatives indicated Assume the variables are restricted to a domain on which the function is defined. z=x8+3y+xy.

Step-by-step explanation:

The question is incomplete. Here is the complete question.

Find the partial derivatives indicated Assume the variables are restricted to a domain on which the function is defined. z=++

a) Zx b) Zy

In differentiation, if y = axⁿ, y' = . Applying this in question;

Given the function z = x⁸++

Note that y is treated as a constant since we are to differentiate only with respect to x.

For Zy;

Here x is treated as a constant and differential of a constant is zero.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
