Answer:
F = 3x +(2.7×10^7)/x
Step-by-step explanation:
The formulas for area and perimeter of a rectangle can be used to find the desired function.
<h3>Area</h3>
The area of the rectangle will be the product of its dimensions:
A = LW
Using the given values, we have ...
13.5×10^6 = xy
Solving for y gives ...
y = (13.5×10^6)/x
<h3>Perimeter</h3>
The perimeter of the rectangle is the sum of the side lengths:
P = 2(L+W) = 2(x+y)
<h3>Fence length</h3>
The total amount of fence required is the perimeter plus one more section that is x feet long.
F = 2(x +y) +x = 3x +2y
Substituting for y, we have a function of x:
F = 3x +(2.7×10^7)/x

<em>Additional comment</em>
The length of fence required is minimized for x=3000. The overall size of that fenced area is x=3000 ft by y=4500 ft. Each half is 3000 ft by 2250 ft. Half of the total 18000 ft of fence is used for each of the perpendicular directions: 3x=2y=9000 ft.
The domain (input values) of the cosine function is all negative and positive angle measures.
Let the function be f(x) = cos(x)
The domain of cos(x) is -∞ < x < ∞
The range is -1 ≤ f(x) ≤ 1
Hence, domain of cos(x) is all (+) and (-) angle measures.
Same goes with sine function as well
For function f(x) = sin(x)
The domain is -∞ < x < ∞ and range -1 ≤ f(x) ≤ 1
However for f(x) = tan(x) the same is not applicable.
Side angle side
angle angle side
side side side
and thats all for now

Previous question Rational numbers prior question delete your full name you accidently wrote in your question for rational numbers by pressing edit icon answered here so your edit is possible ok! Answer is -2t +7t = 5t Step-by-step explanation: question asks for addition only (4t-6t= -2t)+(8t-1t=7t) This question on page = 1) At 2:16 p.m.= -180ft - 40ft = -220ft 2) At 2:17 p.m = -175ft-40ft= -115ft 3) At 2:18 p.m. = -185ft - 40ft = -225ft 4) The difference is show your work by reversal 2:18-2:15 = 3 minutes so the distance is also reversed at (-225) - (-40 )= -225 + 40 = -175
Step-by-step explanation: This is minus - number minus- number = minus number counting bkwards but when when we subtract two minus number with another minus it becomes a plus + just between the brackets see question 4 brackets use. The work is using brackets for question 4.
