Answer:

Step-by-step explanation:
We are given the following in the question:
Controller cost = $135
System cost = $2.50 per foot of pipeline
The total cost depends upon the length of Pole.
Let the system requires F feet of pipeline.
Total cost will be given by the equation:

is the required expression for total cost
F: feet of pipeline required
c(F): Total cost of installation
Answer:
A triangle.
Step-by-step explanation:
The plane would pass through opposite sloping faces of the pyramid and through the base; the shape formed is a triangle.
Hello :
let : A(0,3) B(4,8)
<span>the slope is : (YB - YA)/(XB -XA)
</span>(8-3)/(4-0) = 5/4
same method for 4
it is 0.01 times the value because it is a hundreds time smaller than the other four.
All you need is use sin cos tan for doing this
sin (angle)= O/H
cos (angle)= A/H
tan (angle)= O/A
