Graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x
xx is 0.4. point, 4, point In other words, a change of 1 unit in x corresponds to a change of 0.4, point, 4 units in y.
1 answer:
Answer:
The graph is attached.
Step-by-step explanation:
The graph of the line with the slope and the y-intercept
, has the form
In our case the rate of change is
; therefore we have the equation
The graph of which is attached.

The dimension that would give the maximum area is 20.8569
<h3>How to solve for the maximum area</h3>
Let the shorter side be = x
Perimeter of the semi-circle is πx
Twice the Length of the longer side
Length =
Total area =
area of rectangle + area of the semi-circle.
Total area =
When we square it we would have
This gives
From here we divide by 2
The maximum side would be at
This gives us 20.8569
