Step-by-step explanation:
Hello! We can check to see if the inequality is true by replacing r with 18 as we have been told to find them in which 18 as r makes the equation true.
So our equations to test for are:

We can input 18 as r and then we see the following are correct:
1. No, as a -21 is not greater than -6
2. Yes, as -15 is less than 6.
3. No, as 21 is not greater than 6
4. No, as -15 is not greater than 6.
Cheers!

Answer:
D
Step-by-step explanation:
Accuracy refers to how close measurements are to the "true" value (which is the target in this case), while precision refers to how close measurements are to each other.
Since the arrows fall away from the bullseye and are spread out I would classify this as low accuracy and low precision.
Answer:
Step-by-step explanation:
We can write the given expression as :

As given, f = ∇f.
∇f =
+
+
We can write the partial derivative with respect to x, y and z.
___(Equation 1)
______(Equation 2)
______(Equation 3)
Take equation 2 and integrate with respect to y,

----------Equation 4
Derivate both sides w.r.t x , we get :

or

integrate
a(x,z)=b(z)
put in equation 4 ,
we get :

take derivative wrt z

we can take here:

integrate:

b(z) = C
The function can be written as :
from equation 4 :
Where C is a constant.
