Answer:
That is correct
Step-by-step explanation:
I would say all of them can be model as functions.
<span>model number:
This would be a onto function, meaning that the outputs are not unique.
f(model_1) = f(model_2) = computer_type.
</span><span>part number:
</span>This would mean the function takes in multiple parameters.
f(part_1, part_2, part_3, ...) = computer
<span>serial number:
This is the most obvious one; an one-to-one function:
f(s_num_1) = computer_1;
f(s_num_2) = computer_2;</span>
Answer:
Step-by-step explanation:
66=2(w+5)+2w L=14+5
66=2w+10+2w L=19
66=4w+10
-10
56=4w/4
14=w
Answer:
Rotate a semicircle 180° about its diameter
Step-by-step explanation:
For common figures, the shape of a figure that revolves about a line which is at the base of the figure to give a 3 dimensional shape is the shape of the cross section of the 3 dimensional figure when the angle of revolution is 180° and half the shape of the cross section of the formed 3 dimensional figure, when the angle of revolution is 360°
The cross section of an hemisphere is a semicircle, therefore, the shape of an hemisphere is formed by rotating a semicircle 180° about the diameter (which is the straight line at the "base") of the semicircle
Therefore;
The correct option that gives the revolution that will generate the hemisphere is;
Rotate a semicircle 180° about its diameter.
