First find the gradient by using partial derivatives.
Sub in given point (0,-1,2) for x,y,z
∨
Next, find unit vector from directional vector (0,-1,2) --> (-3,4,-3)
Finally, use dot product on gradient and unit vector to get directional rate of change.
Answer is approx 61.398

Step-by-step explanation:
The given number is 7700.
We need to find the relationship between the values of the digit 7s in it.
The digit in the extreme left is 7 and second no is again 7.
The place value of first 7 is 7000
The place value of second 7 is 700.
Taking ratio of place value of 7 in first 7 and for second 7 as follows :
So, value of first 7 is 10 times that of the value of second 7.
