Answer:
Maximum added area will be 60,000 ft²
Each paddock measure 200 ft by 150 ft, and the paddocks share a 200-ft long side.
Step-by-step explanation:
Consider the provided information.
There is sufficient funding to rent 1200 feet of temporary chain-link fencing.
The plan is to form two paddocks with one shared fence running down the middle.
The total length of fencing is 1200 feet that is same as the total perimeter including that shared line down the middle.
Therefore, the perimeter is
Solve for L
As we know the area of rectangle is A=L×W
Substitute the value of L in above formula.
The above equation makes a downward parabola.
In order to find the maximum, find the vertex of parabola as shown:
Hence, the width should be 200 ft in order to get maximum area,
Therefore, the length will be:
Now substitute the value of L and W in area formula.
A=300×200=60,000
Hence, maximum added area will be 60,000 ft²
Hence, the length should be 300 ft, and each paddock should then be 150 feet long.
Each paddock measure 200 ft by 150 ft, and the paddocks share a 200-ft long side.
<u><em>Answer:</em></u>
He would need to climb 480.97 m
<u><em>Explanation:</em></u>
The ground, the plane to climb and the altitude (100 m) all form a right-angled triangle
Therefore, we can apply the special trig functions.
<u>These functions are as follows:</u>
sin(θ) =
cos(θ) =
tan(θ) =
<u>From the diagram, we have:</u>
θ = 12°
The distance that he needs to climb is the hypotenuse
The altitude = 100 m is the opposite
<u>Therefore, we can use the sin function as follows:</u>
sin(12°) =
hypotenuse =
hypotenuse = 480.97 meters to the nearest hundredth
Therefore, he would need to climb 480.97 meters
Hope this helps :)
