8x=90
90/8= 11.25
x= 11.25
What is the half of the number
Answer:
The answer is when they work 4 hours x=4
Step-by-step explanation:
510 + 80x = 650 + 45x
80x - 45x = 650 - 510
35x = 140
x = 140/35
x = 4 hours
Step-by-step explanation:
We have t(x,y,z) as a scalar function. Divergence and curl are operations that can be done on a vector function. So they are not necessary for a scalar function. Grad is what is used for a scalar function.
Therefore the gradient is the sensible operator on temperature compared to others.
a. Grad T = δT/ δx.(xˆ ) + δT/ δy.(yˆ) + δT/ δz.(zˆ)
b. The gradient of T(x,y,z) gives a measure of the direction and the rate at which temperature changes in all directions.
C. The result is going to be a vector quantity.
I have written out the answer to a in an attachment.
