Answer:
a)
b) , .
c)
Step-by-step explanation:
Remember, if F= <f,g,h> is a vector field and is the operator
- the divergence of F is
- the curl of F is
a)
The divergence of F is
The curl of F is
b)
The divergence of F is
The curl of F is
Since the curl of F is 0 the we will try find f such that the gradient of f be F.
Since , .
Since , .
Since and , then . Thins means that
Therefore,
.
c)
The divergence of F is
The curl of F is
Answer:
21 cm
Step-by-step explanation:
2 sides of a triangle must equal to more than the last side of the triangle. So, 6 + 15 is more than 6 cm, also more than 8 cm, and also more than 18 cm. So the answer must be 21 cm. I hope this helped and please mark me brainliest!
The distance between two points is the number of units between them
The distance between the oak tree and the maple tree is 9 yards
<h3>How to determine the distance?</h3>
From the diagram, we have the following highlights:
- The distance between the maple tree and the end is yards
- The distance between the oak tree and the end is yards
The distance (d) between the oak tree and the maple tree is the difference between the above measurements.
So, we have:
Simplify the expression in the bracket
Subtract
Hence, the distance between the oak tree and the maple tree is 9 yards

Answer:25 in^2
Step-by-step explanation:
d1=10 d2=5
area of rhombus=( d1 x d2)/2
Area of rhombus=(10x5)/2
area of rhombus=50/2
Area of rhombus=25 in^2
