Answer:
Step-by-step explanation:
Let C(x) be the cost to produce x batches of widgets, and let R(x) be the revenue in thousands of dollars.

Profit function = Revenue - cost
So we get profit function by subtracting C(x) from R(x) using algebraic method of subtraction.
Profit function of x
= 
Answer:
other parallel side is 23m
Step-by-step explanation:
Let's assume other parallel sides as 'x'
One of the parallel sides of the trapezium plot measure 18m
so, y=18
distance between the two parallel sides measure 20m
so, h=20
now, we can use area of trapezium formula

now, we can plug values

we can set A=410
and then we can solve for x




Yes as long as one side on a square is the same on another they are the copies of each other
Answer: Just put the numbers of the x and y coordinates onto the graph and draw a line.
