<h2>
Maximum area is 25 m²</h2>
Explanation:
Let L be the length and W be the width.
Aidan has 20 ft of fence with which to build a rectangular dog run.
Fencing = 2L + 2W = 20 ft
L + W = 10
W = 10 - L
We need to find what is the largest area that can be enclosed.
Area = Length x Width
A = LW
A = L x (10-L) = 10 L - L²
For maximum area differential is zero
So we have
dA = 0
10 - 2 L = 0
L = 5 m
W = 10 - 5 = 5 m
Area = 5 x 5 = 25 m²
Maximum area is 25 m²

Answer:
y=2x-5
Step-by-step explanation:
Slope is rise over run, or y/x
The points given were (0,-5) and (-1,-3)
Using y2-y1/x2-x1 we can find the slope.
-3-(-5)/-1-0 = 2/-1 = -2 = slope
Next, we have to find the y-intercept. The y-intercept is where the point on the line meets the y-axis.
This point is shown at -5.
Now, putting our information into y=mx+b (slope-intercept form)
y=2x-5
2 is our slope
-5 is our y intercept
Step-by-step explanation:
65 km / h = 65,000 m / 3600 s
what do we need to multiply 3600 with to get 3 ?
3600 × f = 3
f = 3/3600 = 1/1200
now, we need to multiply 65,000 by the same factor to get how many meters the car is driving in these 3 seconds :
65000 × 1/1200 = 65000/1200 = 54.16666666...
so, rounded, it travels 54 meters in 3 seconds.
Answer:
C. The solution (25, 20) tells the contractor the number of hours on a job where the hourly rate is the same for both billing options.
Step-by-step explanation:
In the graph, the x axis represents the number of hours worked and the y-axis represents the hourly rate.
It is given that the hourly rate is $20.
While seeing the options, clearly, (0, 20), (0, 500) and (20, 25) are not points on the graph.
Hence, the correct option is (C).
