Answer:
The scale factor is 1/3
Step-by-step explanation:
Compare side length XW with RQ, the side length decreases from 15 to 5, which is a shrinking by a factor of 1/3, since 5 is 1/3 of 15. You can check this by comparing the sides WV with RS, and since 8 is 1/3 of 24, the scale factor is 1/3 going from UVWX to STQR.

The rooftops of the village are shaped as square pyramids. If the height of the roof is 5 feet and the length of the sides are 6 feet. What is the volume of the roof?
The volume of the square pyramid-shaped roof with a height of 5 feet and a side length of 6 feet is 60 cubic feet.
A square pyramid has a square base and four triangular sides that come together to form a single point. To calculate the volume of a square pyramid, you can use the formula: 1/3 x Base x Height, where the base is the area of the square base and the height is the height of the pyramid.
In the given scenario, the rooftops of the village are shaped like square pyramids. The height of the roof is 5 feet and the length of the sides is 6 feet. Let us calculate the volume of the roof using the formula mentioned above:
The base of the square pyramid = side * side= 6 * 6= 36 sq. ft, Height of the square pyramid = 5 ft. Volume of the square pyramid= 1/3 * Base * Height= 1/3 * 36 sq. ft * 5 ft= 60 cubic feet. Therefore, the volume of the roof is 60 cubic feet.
Summary: A square pyramid has a square base and four triangular sides that come together to form a single point. The formula to calculate the volume of a square pyramid is 1/3 x Base x Height. The rooftops of the village are shaped as square pyramids with a height of 5 feet and the length of the sides is 6 feet.

Hi! From what I know, your answer should be 5n = 1.75.
This is because all 5 of those n's ultimately equal the large box of 1.75 on the top. Think of it as fractions. if we replaced 1.75 with 1, those n's would each be 1/5.
Evaluate the definite integral (a) √3.5 √7 - 2xdx (b) Ste-2/2dt.
(b) the value of the definite integral ∫[0, 2] \(e^{(-2t/2)}\) dt is -\(e^{(-2)}\) + 1.
(a) To evaluate the definite integral ∫[√3.5, √7] (√7 - 2x) dx:
Let's first find the antiderivative of (√7 - 2x):
∫(√7 - 2x) dx = (√7x - \(x^2\)) - \(x^2\)/2 + C
Now, we can evaluate the definite integral:
∫[√3.5, √7] (√7 - 2x) dx = [((√7 * √7) - \((sqrt7)^2\)) - (√\(7)^2\)/2] - [((√3.5 * √3.5) - (√\(3.5)^2\)) - (√\(3.5)^2\)/2]
Simplifying the expression:
= [7 - 7 - 7/2] - [3.5 - 3.5 - 3.5/2]
= [-7/2] - [-3.5/2]
= -7/2 + 3.5/2
= -3.5/2
= -1.75
Therefore, the value of the definite integral ∫[√3.5, √7] (√7 - 2x) dx is -1.75.
(b) To evaluate the definite integral ∫[0, 2] \(e^{(-2t/2)}\) dt:
Notice that \(e^{(-2t/2)}\) simplifies to e^(-t).
Now, we can evaluate the definite integral:
∫[0, 2] \(e^{(-t)}\) dt = [-\(e^{(-t)}\)] from 0 to 2
= -e\(^{(-2)} - (-e^0)\)
= -\(e^{(-2)}\) + 1

The distance (p) between two parallel sides of the hexagon is approximately 5.4 cm.
We may use trigonometry and the characteristics of a hexagon to determine the separation between two parallel sides of a regular hexagon.
Each internal angle in a regular hexagon is 120 degrees, and the opposing sides are parallel.
We may create an equilateral triangle by connecting the hexagon's center to two of its opposite vertices using two radii.
Let's think about one of the hexagon's equilateral triangles:
An equilateral triangle has just 60-degree inner angles. Each side of the equilateral triangle is 6.3 cm long, just as each side of the hexagon is.
The height (p) of the equilateral triangle, which is the separation between two parallel sides of the hexagon, can be calculated using trigonometry.
The following formula can be used to get the height:
p = sin(60 degrees)side length
Putting the values,
p = sin(60 degrees)6.3 cm
Now, let's calculate the value of p:
p = sin(60 degrees)6.3 cm
p = (√3/2)6.3 cm
p = 1.732/2 × 6.3 cm
p ≈ 5.4435 cm
Therefore, the distance (p) between two parallel sides of the hexagon is approximately 5.4 cm.

Seven pounds of raw material are needed to manufacture each unit of a certain product. Express the number of units that can be produced from n pounds of raw material using either the floor or the ceiling notation. Which notation is more appropriate?
The number of units that can be produced from n pounds of raw material using the ceiling notation is ⌈n/7⌉.
To determine the number of units that can be produced from n pounds of raw material, we need to divide the total amount of raw material by the amount of raw material needed to manufacture one unit. Let x be the number of units that can be produced from n pounds of raw material. Then:
x = n ÷ 7
If we use the floor notation, denoted by ⌊x⌋, we obtain the largest integer less than or equal to x:
⌊x⌋ = ⌊n/7⌋
This notation gives the maximum number of whole units that can be produced from n pounds of raw material, but it does not take into account any leftover raw material that cannot be used to make another unit.
If we use the ceiling notation, denoted by ⌈x⌉, we obtain the smallest integer greater than or equal to x:
⌈x⌉ = ⌈n/7⌉
This notation gives the maximum number of units that can be produced from n pounds of raw material, taking into account any leftover raw material that can be used to make a partial unit.
In this case, since the amount of raw material needed to manufacture one unit is a whole number, using the ceiling notation is more appropriate.
This ensures that we do not waste any raw material and produce as many units as possible.

What do the following two equations represent? x+3y=5x+3y=5x, plus, 3, y, equals, 5 4x+12y=204x+12y=204, x, plus, 12, y, equals, 20 choose 1 answer:
The two equations x + 3y = 5 and 4x + 12y = 20 represent a system of linear equations.
To solve this system, we can use the method of substitution. Let's begin by solving the first equation for x in terms of y:
x + 3y = 5
Subtract 3y from both sides:
x = 5 - 3y
Now, substitute this expression for x into the second equation:
4x + 12y = 20
Replace x with 5 - 3y:
4(5 - 3y) + 12y = 20
Distribute the 4:
20 - 12y + 12y = 20
Combine like terms:
20 = 20
The equation 20 = 20 is true for any value of y. This means that the system of equations has infinitely many solutions. In other words, any pair of x and y values that satisfy the equation x + 3y = 5 will also satisfy the equation 4x + 12y = 20.
To summarize, the two equations x + 3y = 5 and 4x + 12y = 20 represent a system of linear equations that has infinitely many solutions.

Shape = Right-angled triangleLegs = x and x + 5Hypotenuse = x + 6Solving further, we make use of the Pythagoras theorem of a right triangle
Mathematically, this theorem states that:
Hypotenuse² = Adjacent² + Opposite²
This can also be represented as
Hypotenuse² = Leg² + Other leg²
So, we have
(x + 6)² = x² + (x + 5)²
Evaluate the exponents
x² + 12x + 36 = x² + x² +10x + 25
Evaluate the like terms
x² - 2x - 11 = 0
Solve for x using quadratic formula
\(x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\)
So, we have
\(x = \frac{2 \pm \sqrt{(-2)^2 - 4 * 1 * -11}}{2 * 1}\)
Evaluate
x = -2.5 and x = 4.5
The value of x cannot be negative
So, we have
x = 4.5
Recall that
Legs = x and x + 5Hypotenuse = x + 6So, we have
Legs = 4.5 and 4.5 + 5 = 9.5Hypotenuse = 4.5 + 6 = 10.5Hence, the side lengths are 4.5, 9.5 and 10.5 units

Find the limit !!!!!!
Answer:
1/8.
Step-by-step explanation:
Use l'Hopitals rule - we find the derivative of top and bottom of the fraction.
Derivative of the numerator = 0 - 1/2 (16 - x)^-1/2 -1
= 1 / [ 2 * (16 - x)^1/2
Derivative of the denominator = 1
When x approaches 0 this is 1 / (2*4)
= 1/8.
Another way to do this is to multiply top and bottom by 4 + (16 - x)^1/2
This becomes 16 - (16 - x) / x(4 + (16-x)^1/2)
= 1 / (4 + (16 + x)^1/2
When x ---> 0
this = 1 /(4 + 4)
