Answer:
the cost of each notebook is $4.8
Step-by-step explanation:
Cost of each notebook= ?
Cost of a poster = $6
Total amount she spent = $20.40
If we subtract the cost of poster from total amount we get the cost of 3 notebooks.
$20.40-$6
=$ 14.4
It means the cost of 3 notebooks = $14.4
To find the cost of each notebook divide the cost of 3 notebooks by the number of books.
=14.4/3
=$4.8
Thus the cost of each notebook is $4.8....
The indicated partial derivative of z is; 1.
<h3>Partial derivatives</h3>
According to the question:
- We are required to determine the partial derivative of the variable z.
The given value of z is; Z = u, v, −w
Hence, it follows that;
d³z = ∂/∂u(u) + ∂/∂v(v) - ∂/∂w(w)
Ultimately, the value of ∂³z is; 1.
