A closed top box with a square base is to have a volume of 4000 cubic inches. What are the dimensions that will minimize the amount of material used to build the box?.
The minimum dimensions to minimize the amount of material is 15.87 x 15.87 x 15.87 inch.
We need to know about the minimum function to solve this problem. The minimum function can be defined as the minimum value of the variable. It can be calculated by the derivative of the function. The minimum function can be written as
f'(s) = 0
where f'(s) is the derivative function
From the question above, the given parameter is
V = 4000 inch³
The cubic volume can be written as
s² x h = 4000
where s is the length of the base area and h is the height of the box.
the minimum value of the box refer to its surface area, hence
f(s) = 4sh + 2s²
f'(s) = 4h + 4s
4h + 4s = 0
h = s
It means that the length of the base area and the height must have the same dimension. The minimum volume should have a cube shape
V = s³
s³ = 4000
s = 15.87 inch

The required equation of the line is y = (7/4)x + 2.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The given coordinate of the point on the line is ; (-4, -5) and the slope is 7/4
Let the required equation of the line is
⇒ y - y₁ = m [x -x₁]
x₁ = -4, y₁ = -5 and m = 7/4
Substitute values in the equation, we get
y - (-5)= (7/4)(x - (-4))
y + 5 = (7/4)(x + 4)
y + 5 = (7/4)x + (7/4)4
y = (7/4)x + 7 - 5
y = (7/4)x + 2
Therefore, the required equation of the line is y = (7/4)x + 2.

The perimeter of the square can be expressed as either S+S+S+S or 4×S
How to write two different expressions to represent the perimeter of a square?
Perimeter is the distance around the edge of a shape. It can be found by adding up the side lengths of the shapes
Given: a square with a side length of S. Thus, the perimeter can be expressed as:
Perimeter = S + S + S + S = 4S
Since there are 4 equal sides each having a length of S. Thus, we can also write perimeter as:
Perimeter = 4 × S = 4S
Therefore, we can conclude the same expression are the same since they both have the same value of 4S

identify the vertex, axis of symmetry, maximum or minimum, and domain and range of each function. f(x)
The vertex is (7, -27)
The line of symmetry is x = 7.
The minimum is y = -27
The domain is the set of all real numbers.
The range is y ≥ -27.
Given,
The quadratic equation is as follows:
f(x) = (x - 7)^2 - 27
The quadratic equation is in vertex form, hence if the vertex is (h, k), the vertex form will be as follows:
f(x) = (x - h)^2 + k
Then the vertex in this instance is (7, -27).
A line of the form x = h is the line of symmetry, and in this instance the line is x = 7.
The minimum of the quadratic equation is y = -27 since the function has a positive leading coefficient, indicating that the vertex is a minimum.
Finally, the domain is the set of all real numbers, much like the domain of any quadratic equation.
The range includes all real numbers that are greater than or equal to -27.

The amount that Ms. Takata has left to spend is $100.26 .
In the question ,
it is given that ,
total amount that Ms. Takata can spend on redecorate her room = $480
the cost of 1 curtain is = $48.25
the cost for 3 curtain = 3*48.25 = 144.75
the cost of dresser = $234.99
the amount left to spend can be represented by
the amount left to spend = total amount - ( cost of 3 curtain + cost of dresser)
= 480 - (144.75 + 234.99)
= 480 - 379.74

What is Pythagoras' Theorem?
The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares. The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides. Look at the triangle ABC,is present. The base in this equation is AB, the height is AC, and the hypotenuse is BC.
In the given figure, we have:
A right angles triangle.
So, the Hypotenuse meaure is 14.2 cm;
The measure of the base side is 3.6 + 9.7 cm = 13.3 cm;
So, we can find the perpendicular side length using the Pythagorean Theorem
So, using the Pythagoras theorem,
[tex]c^{2} = x^{2} + y^{2}[/tex]
[tex](14.2)^{2} = (13.3)^{2} + x^{2}[/tex]
201.64 = 176.89 + [tex]x^{2}[/tex]
24.75 = [tex]x^{2}[/tex]
So, x = 4.97
So, The perpendicular side is 4.97 cm;
Now using the Pythagoras theorem again in the smaller triangle, we get:
[tex](3.6)^{2} + (4.9)^{2} = x^{2}[/tex]
12.96 + 24.01 = [tex]x^{2}[/tex]
36.97 = [tex]x^{2}[/tex]
So, The value of x is 6.08 cm;
Hence,
The value of x is 6.08 cm;.

A new car is purchased for \$14,000$14,000 and over time its value depreciates by one half every 5.5 years. What is the value of the car 18 years after it was purchased, to the nearest hundred dollars
Answer:
$1400
Step-by-step explanation:
You want the value of a car 18 years on if its initial value was $14,000 and its value is cut in half every 5.5 years.
Exponential modelThe value of the car can be modeled by the exponential equation ...
value = (initial value) × (growth factor)^(t/(growth period))
where "growth period" is the period applicable to the "growth factor."
ApplicationHere, the problem statement tells us ...
initial value = $14,000growth factor = 1/2growth period = 5.5 yearsSo, our exponential model is ...
value = 14,000·(1/2)^(t/5.5)
When t=18 years, this is ...
value = 14,000(1/2)^(18/5.5) = 14000(1/2)^(36/11) ≈ 14000·0.103469 ≈ 1449
The value after 18 years is about $1400.

She need 6 points to score in her 12th game in order to decrease the interquartile range by 1 point.
What is Interquartile range?
An Interquartile range is one of the measure of variability that measures the spread of middle 50% of the data.
Given that;
A basketball player recorded for 11 consecutive games her points as;
13, 20, 15, 22, 24, 21, 18, 20, 25, 17, 27
Now,
Since, We know that;
The formula for the interquartile range is,
⇒ IQR = Q₃ - Q₁
Where, Q₃ is the third quartile , Q₁ is the first quartile.
Here, We arrange the points in the increasing order as;
⇒ 13, 15, 17, 18, 20, 20, 21, 22, 24, 25, 27
The first quartile is calculated as;
Q₁ = (n + 1) / 4 th term
Where, n is number of terms.
Q₁ = (11 + 1) / 4
Q₁ = 3rd term
Q₁ = 17
The third quartile Q₃ is calculated as;
Q₃ = 3(n + 1) / 4
Q₃ = 3 x 3
Q₃ = 9th term
Q₃ = 24
Thus, The interquartile range is,
⇒ IQR = Q₃ - Q₁
⇒ IQR = 24 - 17
⇒ IQR = 7
So, The desired interquartile range is,
⇒ IQR = 7 - 1
⇒ IQR = 6
Therefore, She need 6 points to score in her 12th game in order to decrease the interquartile range by 1 point.
