Answer:
6.4 kilometer
==============================
Step-by-step explanation:
See the attached figure.
Let Julian starts from point O (0,0)
Julian jogs 2 kilometers east ⇒ arrived to point A (2,0)
4 kilometers north ⇒ arrived to point B (2,4)
and then 7 kilometers west ⇒ arrived to point C (-5,4)
How far is Julian from his starting position?
So, it is required to find the distance OC
From the graph OC =
So, the distance from his starting position ≈ 6.4 km (to the nearest tenth of a kilometer)
Answer:
Therefore the dimensions of the garden is 16 feet by 13 feet.
Step-by-step explanation:
Let the length of the garden be x and the width of the garden be y.
Given that the area of the rectangular garden is 208 square feet.
Therefore,
xy =208
Again given that,
The garden is to be surrounded on three sides by a brick wall costing $ 8 per feet and the remaining sides by a fence costing $5 per feet.
The perimeter of the rectangle is = 2(length+ breadth)
= 2(x+y)
=2x+2y
The total cost of fence
= (16x+ 8y +5y)
To find the maximum or minimum point, we need to find out and set =0.
Then
Again
Therefore at x= 13 , the cost is minimum.
Therefore x = 13 feet.
The other side of the garden is feet = 16 feet.
Therefore the dimensions of the garden is 16 feet by 13 feet.
