A rectangle has length 72 cm and width 56 cm. A second rectangle has the same area as this one, but its width is 21 cm. Do these quantities (length and width) vary directly or inversely?
The length and the width vary inversely.
What is variation?A variation is a relation between a set of values of one variable and a set of values of other variables.
In the equation y = mx + b, if m is a nonzero constant and b = 0, then you have the function y = mx (often written y = kx), which is called a direct variation.
If first rectangle length = 72cm and width = 56cm
Then, area = length x width = 72 x 56 = 4032[tex]cm^{2}[/tex]
If length of second rectangle = x
and width = 21
Area of second rectangle = 21x
so both areas are equal, which means
21x = 4032
x = 4032/21
x = 192cm
Since the first rectangle had a width of 56cm and length, 72 and second rectangle has a reduced width 21 cm and an increased length 192cm. it means that the length and the width vary inversely since the reduction in width led to an increase in length.
In conclusion, the two quantities length and width vary inversely.

a rectangular storage container without a lid is to have a volume of 10m3. the length of its base is twice the width. material for the base costs 10$ per square meter. material for the sides costs 6$ per square meter. find the cost of materials for the least expensive such container.
The cost of materials for the least expensive such container is 245.31 dollars .
Suppose the width of container is x (m),
length of the base of container is 2x (m)
the base area of container is (length × width)sq. m i.e 2x² meter².
Since the volume of container is 10 m³.
the height of container = area of container/ volume of container
height of container= 10/2x² m = 5/x² m
The cost of making such container is cost of base = 2x²*10 = 20x².
cost of sides of container = (2×2x × 5/x² + 2× x × 5/x²)×6 = 180/x
The overall cost is hence the sum of the base and the sides: f(x) = 20x² + 180/x
The get the minimum,
df(x)/dx = 20×(2x - 9/x²) = 0
so 2x = 9/x^2 => 2x = 2.0800 ==> x = 1.651 m

Hi! I can’t figure out m<4 and m<5. Can anyone help me?
Answer:
Step-by-step explanation:
You are sorta on the right track, but .... ∠3+81°+∠4 =180°
along with 88°+∠1=180°
∠1-92°
I know why you put 88° for ∠2 but , it's only 88° from a line parallel to that top line, not the hypotenuse of the triangle. But good idea, just not able to apply that here.
you've nicely marked the two parallel lines so we know that ∠3 will math the other 64° angle , now you can solve for ∠2
∠1=92° and ∠3=64° so ∠2 must equal 180-92-64=24°
∠2=24°
now solve for ∠4
180-64-81=∠4
∠4=35°
finally we can get ∠5
180-35-64=∠5
∠5=81°
and , we should have also seen that ∠5 would be the same as the 81° angle above it by ∠3 and ∠4 since those lines are parallel.

rectangles beneath a semicircle a rectangle is constructed with its base on the diameter of a semicircle with radius 5 and its two other vertices on the semicircle. what are the dimensions of the rectangle with maximum area
Using the area of rectangle, the dimensions of the rectangle with maximum area are 5√2 and 5/√2.
In the given question we have to find the dimensions of the rectangle with maximum area.
Given Semicircle Radius is 5.
As we know that standard equation of circle is [tex]x^2+y^2=a^2[/tex]
a=5, so the equation is [tex]x^2+y^2=(5)^2[/tex]
[tex]x^2+y^2=25[/tex]
Therefore, Half circle y=[tex]\sqrt{25-x^2}[/tex]
Area of Rectangle(A) =xy
Because Half of the rectangle is lies in first quadrant and half lies in second quadrant
Therefore,
Area of Rectangle(A) = 2xy
Now putting the value of y
Area(A) = 2x[tex]\sqrt{25-x^2}[/tex]
Here we need to maximize the area of Rectangle, so find derivative and set equal to zero.
A'= [tex]\frac{d}{dx}(2x\sqrt{25-x^2})[/tex]
A'= 2[tex][x\frac{d}{dx}\sqrt{25-x^2}+\sqrt{25-x^2}\frac{d}{dx}x][/tex]
A'= 2[tex][x\cdot\frac{-x}{\sqrt{25-x^2}}+\sqrt{25-x^2}\cdot1][/tex]
A'= 2[tex][\frac{-x^2}{\sqrt{25-x^2}}+\sqrt{25-x^2}][/tex]
A'= 2[tex](\frac{-x^2+25-x^2}{\sqrt{25-x^2}})[/tex]
A'= 2[tex](\frac{25-2x^2}{\sqrt{25-x^2}})[/tex]
For critical Number A' = 0
2[tex](\frac{25-2x^2}{\sqrt{25-x^2}})[/tex] = 0
25-2x^2 = 0
2x^2=25
x^2=25/2
x=±√25/2
x=±5/√2
Therefore,
Base of the Rectangle = 2x
Base of the Rectangle = 2×5/√2
Base of the Rectangle = 5√2
and
height of rectangle = [tex]\sqrt{25-x^2}[/tex]
height of rectangle = [tex]\sqrt{25-(5/\sqrt{2})^2}[/tex]
height of rectangle = [tex]\sqrt{25-(25/2)}[/tex]
height of rectangle = √(50-25)/2
height of rectangle = √25/2
height of rectangle = 5/√2
Hence, the dimensions of the rectangle with maximum area are 5√2 and 5/√2.

To reach the break-even point, the publisher should sell 40,000 books.
A break-even point (BEP) is the point where revenues = total cost. Hence, at this point, the company does not gain profit or loss.
On the other hand, total cost is calculated as:
Total cost = fixed cost + variable cost
Where variable cost depends on the number of units produced.
Therefore,
Total cost = fixed cost + number of unit produced x cost per unit
Parameters given in the problem:
fixed cost = h. 400,000
unit cost = h. 35
selling price = h.45 per unit
Let p be the number of books sold. Then,
Revenues = 45 x p
Total cost = 400,000 + 35 x p
At break-even point:
Revenues = total cost
45 x p = 400,000 + 35 x p
10 p = 400,000
p = 40,000
Hence, the break-even point is 40,000 books

As given in the question,
Condition for the expression:
Sally and Anne both went for a movie.
Each one purchased a drink.
Shared one popcorn and one veggie bought by them.
Consider movie ticket price = 9
drink price = 1.35
Popcorn price = 3.50
Veggie price = 1.74
Explanation for different expressions are:
1. one-half (9 + 1. 35 + 3. 50 + 1. 74)
Here sum of all the amount is divided equally, which is not correct as movie ticket and drink they have purchased individually.
2. 9 + 1. 35 + one-half (3. 50 + 1. 74)
This is correct option as it represents :
Movie ticket price = 9
Drink = 1.35
one-half (3. 50 + 1. 74) = one popcorn and one veggie divided equally.
3. 18 + 2. 70 + one-half (3. 50 + 1. 74)
As per consideration of price this is not correct option.
Movie ticket price =18
Drink = 2.70
one-half (3. 50 + 1. 74) = one popcorn and one veggie divided equally.
4. 9+1. 35+2(3. 50+1. 7)
This is not correct option as popcorn and veggie price is doubled.
Therefore, expression which represents the amount of money spend by each woman is equal to [ 9 + 1.35 + (one- half)(3.50 + 1.74)].

The table shows the closing stock prices of a new energy company for the past 5 days. One of the closing prices is missing from the table. The 5-day simple moving average is $54.27. The closing price of the stock on Monday, Tuesday, Wednesday, and Friday was $52.45, $53.18, $52.37, and $57.11. We need to find the closing price on Thursday. Let the missing value of the stock price be denoted by the variable "x". The average is the sum of all the values divided by the total number of values. We can solve the given equation.
A = (52.45 + 53.18 + 52.37 + x + 57.11)/5
54.27 = (52.45 + 53.18 + 52.37 + x + 57.11)/5
54.27*5 = (52.45 + 53.18 + 52.37 + x + 57.11)
271.35 = 215.11 + x
x = 271.35 - 215.11

What is Factor theorem?A polynomial can be factored, and its roots can be discovered using the factor theorem. The polynomial residual theorem is indeed a special instance of this one.
A polynomial f(x) has a factor (x-a), as was noted in the beginning, if and only if f(a) = 0.
As per the given equation in the question,
3x⁵ + 25x⁴ + 26x³ - 86x² + 76x - 48
The function can be written as:
f(x) = g(x).h(x) (i)
The real solutions from the graph is,
x₁ = -6, x₂ = -4 and x₃ = 1.
So,
g(x) = (x + 6) × (x + 4) × (x - 1)
g(x) = (x² + 10x + 24) × (x - 1)
g(x) = x³ + 9x² + 14x - 24.
Now, substitute the values in (i)
3x⁵ + 25x⁴ + 26x³ - 86x² + 76x - 48 = (x³ + 9x² + 14x - 24) × (ax² + bx + c)
Therefore,
ax⁵ = 3⁵
a = 3.
-24c = -48
c = 2.
-24(bx) + 14(cx) = 76x
-24b + 28 = 76
b = -2.
The equation for non-real solution:
h(x) = 3x² - 2x + 2.
Δ = b² - 4ac = (-2)² - 4(3)(2) = -20
x₁ = (2 + √20)/6 = (1 + √5 i)/3

1000,500,250,125 arithmetric, geometric, or neither
Answer:
[tex] G [/tex]eometric.
Step-by-step explanation:
To get the common ratio in a Geometric Progression (GP), T2/a(T1). a(T1) = 1000, T2 = 500.
So, 500/1000 = 1/2. Therefore, common ratio = 1/2
Now, multiply by the the given term to find the next term i.e
1/2 × 1000 = 500, 1/2 × 500 = 250, 1/2 × 250 = 125, 1/2 × 125 = 62.5, etc.
I hope this helpsAt 80°F, a certain insect chirps at a rate of 102 times per minute, and at 87°F, they chirp 116 times per minute. Write an equation in slope-intercept form that represents the situation.
The situation can be represented in a linear equation using a slope-intercept form as y = 2x - 58
Linear EquationA linear equation is an algebraic equation of the form y = mx + b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.
Data;
y₁ = 102y₂ = 116x₁ = 80x₂ = 87We can find the slope of the line using
m = y₂ - y₁ / x₂ - x₁
Substituting the values into the equation
m = 116 - 102 / 87 - 80
m = 2
We can find the y-intercept using any point.
y = mx + c
102 = 2(80) + c
102 = 160 + c
c = -58
The equation in slope-intercept form will be y = 2x - 58
