Answer:
20 ft by 60 ft
Step-by-step explanation:
"What should the dimensions of the garden be to maximize this area?"
If y is the length of the garden, parallel to the stream, and x is the width of the garden, then the amount of fencing is:
120 = 3x + y
And the area is:
A = xy
Use substitution:
A = x (120 − 3x)
A = -3x² + 120x
This is a downward facing parabola. The maximum is at the vertex, which we can find using x = -b/(2a).
x = -120 / (2 · -3)
x = 20
When x = 20, y = 60. So the garden should be 20 ft by 60 ft.
Answer:
Step-by-step explanation:
20-pack of Dr. Pepper cost $5.50 . As per this deal
Cost of one pack = 5.5/20 = $ 0.275
a 6-pack cost $1.50.As per this deal
Cost of one pack = 1.50/6 = $ 0.25
A 6-pack cost $1.50 is the better deal.
Answer:
13 units
Step-by-step explanation:
So the length of those 2 points is 6+6 = 12.
The height would be 8-3 =5
Using pythagoras, you can find out the length of the line joining the 2 points so:
units
Slope= 3/2
