Min cost = $464.76
Dimensions = 11.619 feet by 5.164 feet
Each value mentioned above is approximate.
========================================================
Explanation:
x = horizontal dimension
y = vertical dimension
xy = 60
y = 60/x
The amount of outer fencing needed is 2x+2y feet, aka the perimeter of the largest rectangle.
There are 5 vertical inner fences, so we need 5y feet of inner fencing.
Let's set up the cost function.
Cost = 10*(amount of outer fencing) + 5*(amount of inner fencing)
C = 10*(2x+2y) + 5*(5y)
C = 20x+20y+25y
C = 20x+45y
Plug y = 60/x into the cost function.
C = 20x+45y
C = 20x+45(60/x)
C = 20x + (2700/x)
Then use either calculus or a graphing calculator to find the lowest point on the cost curve is roughly located at (11.619, 464.758)
Use the x value x = 11.619 to find its paired y value
y = 60/x
y = 60/11.619
y = 5.16395558998192
y = 5.164
The entire enclosure should be roughly 11.619 feet by 5.164 feet
The total cost is minimized at approximately $464.76
Answer:
11.619 by 5.164 feet$464.76 minimum costStep-by-step explanation:
You want the dimensions and cost of a rectangular enclosure with an area of 60 square feet and 5 internal partitions. The cost of outside fence is $10 per foot, and the cost of partition fence is $5 per foot.
SetupLet x represent the length of the enclosure, and y the width (and the partition length). Then we have ...
xy = 60
10(2x) = cost fencing for length
10(2y) +5(5y) = cost of fencing for width
We know the cost will be minimized when the cost of fence for the length is equal to the cost of fence for the width.
20x = 45(60/x)
Solutionx² = 135 . . . . . . . . . . . multiply by x/20
x = 3√15 ≈ 11.619 . . . .square root
y = 60/(3√15) = (4/3)√15 ≈ 5.164 . . . . . find y
Then the cost is ...
2(10(2x)) = 120√15 ≈ 464.76 . . . . minimum cost
The enclosure is 11.619 by 5.164 feet, for a cost of $464.76.

The final interval notation is F ∩ H = [7, 4] & F ∪ H = [-∞, ∞].
What is the interval notation?
A set of real numbers known as an interval in mathematics contains all real numbers falling inside any two of the set's numbers. For instance, the interval containing 0, 1, and all integers in between is the set of values x satisfying 0 x 1.
We have,
F and H are sets of real numbers defined as follows.
F = { v l v < 4}
H = { v l v ≥ 7}
F is the set of all real numbers that are less than or equal to 4. H is the set of real numbers greater than 7.
F U H is the union (or combination) of the two sets, so it is the set of all real numbers that are less than equal to 3 or greater than 6:
F ∩ H is the set of real numbers that are in both sets; but since F is less than or equal to 4 and H is greater than 7, there are no numbers that are in both sets. Hence the answer is the empty set, Ø:
F ∩ H = Ø
F ∩ H = [7, 4]
F ∪ H = [-∞, ∞]
Hence, the final interval notation is F ∩ H = [7, 4] & F ∪ H = [-∞, ∞].

The manufacturer's suggested retail price (MSRP) for a particular car is $25020, and it is expected to be worth $14212 in 4 years.
a) Find a linear depreciation function for this car.
(b) Estimate the value of the car 5 years from now.
(c) At what rate is the car depreciating?
Answers
The linear depreciation function is: Depreciation = [tex]\frac{Cost-scrap value}{Estimated life span}[/tex], (b) the value after five years is $11510 and (c) rate of depreciation is 11%
How to calculate depreciation?We should know that depreciation is a loss on a fixed asset over the accounting period that benefited from it.
The given parameters are
Cost of the asset (MSRP)= $25020
Scrap value = $14212
Estimated life span = 4 years
a. Applying the depreciation model
Deprecation = [tex]\frac{Cost of asset - scrap value}{estimated life span}[/tex]
Depreciation = [tex]\frac{25020-14212}{4}[/tex]
depreciation = 10808/4
Dep. = $2702
(b) Note that the accumulated depreciation after 5 years is 2702*5
=$13510
The value of the car after 5 years is $(25020-13510)
=$11510
(c) The rate of depreciation is determined by the model
% dep. = 1-[tex]\sqrt[n]{\frac{s}{c} }[/tex]
where n= number of years
s=scrap value
c cost of the asset
Applying the formular we have
% dep - 1-[tex]\sqrt[5]{\frac{14212}{25020} } = 1-\sqrt[5]{0.5680}[/tex]
% dep= 1-0.89
=0.11*100
=11%
In conclusion, the linear depreciation function is (Cost - Scrap value)÷Number of years, the value of the car 5 years from now is $11510 and the rate of depreciation is 11%

Answers
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
The probability of pulling a green one and then, without replacing it, pulling a blue one is 0.021.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Total number of balls = 20
Red = 5
Blue = 4
Green = 2
Brown = 4
Yellow = 5
The probability of pulling a green one.
= 2/20
= 1/10
Number of balls remaining = 20 - 1 = 19
The probability of pulling a blue without replacing the first green one.
= Number of blue balls / Total number of remaining balls
= 4/19
Now,
The probability of pulling a green one and then, without replacing it, pulling a blue one.
= 1/10 x 4/19
= 4/190
= 2/95
= 0.021

In trigonometry, there are six functions of an angle that are often utilised. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their names.
Given,
sin (2x)cos(6x) - cos(2x)sin(6x) = - 0.8
Let, assume 2x = A and 6X= B
As we know, sin (A-B) = sin A cos B - cos A sin B
Putting the value of 2x and 6x in the given equation, we get
or, sin A cos B - cos A sin B = -0.8
or, sin (A-B) = -0.8
or, sin (2x-6x) = - 0.8
or, sin (-4x) = - 0.8
or, - sin 4x = - 0.8
or, sin 4x = 0.8
Apply sin on both side we get,

Answers
1.67 pounds flour we get per dollar.
What does pounds mean in weight?Pound, avoirdupois weight unit equivalent to 16 ounces, 7,000 grains, or 0.45359237 kg, and troy and apothecaries' weight unit equal to 12 ounces, 5,760 grains, or 0.3732417216 kg The symbol lb comes from the Roman predecessor of the contemporary pound, the libra.
Given,
Cost for 2 pounds of flour = $ 1.20
Cost per pound of flour = $ 1.20 /2

Now for 2 dollar we get flour = 2 pounds.
for 1 dollar we will get flour = 2/1.20 pounds
