Answer:
4
Step-by-step explanation:
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:
The length of the office is 36.4 ft
Step-by-step explanation:
The length of the classroom = 20 ft long
The length of the office = 20 ft + 82% of the classroom length
Now, 82 % of classroom length = 82 % of 20 ft
⇒
or, 82% of 20 ft = 16.4 ft
⇒The length of the office = 20 ft + 16.4 ft = 36.4 ft
Hence, the length of the office = 36.4 ft
Answer:
Part 1) The engine speed that maximizes torque is
Part 2)The maximum torque is
Step-by-step explanation:
<u><em>The correct equation is</em></u>
This is the equation of a vertical parabola open downward (because the leading coefficient is negative)
The vertex represent a maximum
The x-coordinate of the vertex represent the engine speed that maximizes torque
The y-coordinate of the vertex represent the maximum torque
Solve the quadratic equation by graphing
using a graphing tool
The vertex is the point (3.093,74.683)
see the attached figure
therefore
The engine speed that maximizes torque is
---> because is in thousands of revolutions per minute
The maximum torque is
