Answer:
No
Step-by-step explanation:
f(x) = x²
f(3) = 3²
= 3 × 3
= 9 Not 16
also
√16 = 4
Answer:
1/9
Step-by-step explanation:
Answer:

Step-by-step explanation:
In order to find the answer we need to calculate the directional derivative:


The gradient of f is:

The unit vector can be found as:

The directional derivative at the point is:

Finally, the problem tell us that the point moves a distance of 0.1 units. Hence f(x,y,z) will move:

Answer:
50
Step-by-step explanation:
The range is 50 because the maximum number is 90 and you subtract that from 40 which gives you 50.
90= maximum
40= minimum
90-40=50
