A prism would beat a sphere in a competition because a prism has more sides and angles to outmaneuver the sphere, which is a single-sided shape with no angles.
To understand the riddle, one must consider the properties of both a prism and a sphere. A prism is a polyhedron with two congruent and parallel faces (called bases), and its sides are parallelograms.
The number of sides a prism has depends on the shape of its base. For example, a triangular prism has five faces (two triangular bases and three rectangular sides), while a hexagonal prism has eight faces (two hexagonal bases and six rectangular sides).
On the other hand, a sphere is a perfectly round geometrical object in three-dimensional space that is the surface of a ball (viz., the geometric object consisting of all points in three-dimensional space at a distance r from a central point). Unlike a prism, a sphere has no edges or vertices, and it has only one surface with no sides.
In a competition where maneuverability and the ability to approach from different angles are advantageous, a prism would have more options to outmaneuver a sphere. A prism can present multiple faces to the sphere, potentially confusing or disorienting it, while the sphere, being uniform in all directions, has no such advantage. The prism's angles and edges could also be used strategically to deflect or redirect the sphere, giving the prism a competitive edge.
Therefore, the riddle plays on the geometric properties of the two shapes to suggest that in a hypothetical competition, the prism's multiple faces and angles would allow it to outperform the sphere, which has a single continuous surface and no angles to leverage.
The lengths of the three sides of a triangle are given. Classify each triangle as acute, right or
obtuse.
30, 40, 50
1)
Triangle with side lengths 30, 40, and 50 is a right triangle.
To classify the triangle based on the lengths of its sides, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
For the given lengths of sides:
[tex]\(a = 30\)[/tex]
[tex]\(b = 40\)[/tex]
[tex]\(c = 50\)[/tex]
We can check if the triangle is a right triangle:
[tex]\[c^2 = a^2 + b^2\][/tex]
Substituting the values:
[tex]\[50^2 = 30^2 + 40^2\][/tex]
[tex]\[2500 = 900 + 1600\][/tex]
[tex]\[2500 = 2500\][/tex]
Since [tex]\(2500 = 2500\)[/tex], the Pythagorean theorem holds true, meaning this triangle is a right triangle.
So, the given triangle with side lengths 30, 40, and 50 is a right triangle.
Find the cost price if the selling price is $1800 and profit is $10%
Answer:$1636.4
Step-by-step explanation:
Selling price(sp)=$1800
Profit%=10%
Cost price(cp)=?
Profit%=(sp-cp)/cp x 100
10=(1800-cp)/cp x 100
Cross product
10cp=100(1800-cp)
Open brackets
10cp=180000-100cp
Collect like terms
10cp+100cp=180000
110cp=180000
Divide both sides by 110
110cp/110 = 180000/110
cp=1636.4
Cost price is $1636.4
Answer: Cost Price = $1, 636.36
Step-by-step explanation:
Given from the question Selling price (SP)= $1800; Profit%= 10%= 10/100 = 0.1
Cost price(CP)= ??
Profit% is derived by the formula
=(SP-CP)/ CP x 100
0.1 = (1800 - CP)/CP x 100
Then we cross multiply
0.1 x 100 x CP = 1800 - CP
10 CP = 100(1800 - CP)
Open the bracket
10 CP=180000 - 100CP
Divide both sides by 10
CP = 180000 - 100CP/10
CP = 18000 - 10CP
Combine like terms
CP + 10CP = 18000
11CP = 18000
Divide both sides by 11
CP = 18000/11
CP = $1, 636.36

cos^2x-sin^2x/sin^2x+sinxcosx=cotx-1
Answer:
[tex]\bold{\frac{(cosx-sinx)}{(sinx)}}=\bold{\frac{cosx-sinx}{sinx}}[/tex]
Step-by-step explanation:
[tex]\frac{cos^2x-sin^2x}{sin^2x+sinxcosx}=cotx-1[/tex]
We're going to start by manipulating the left side of the equation and making it the same form as [tex]cotx-1[/tex].
Start by applying the difference of two squares formula to the numerator, like so:
[tex]\frac{(cosx+sinx)(cosx-sinx)}{sin^2x+sinxcosx}[/tex]Now simplify the denominator by expanding the [tex]sin^2x[/tex].
[tex]\frac{(cosx+sinx)(cosx-sinx)}{(sinx)(sinx)+sinxcosx}[/tex]The denominator can even be further simplified since both addends (when added together = a sum) have the common factor of [tex]sinx[/tex]. Factor it out.
[tex]\frac{(cosx+sinx)(cosx-sinx)}{(sinx)(sinx+cosx)}[/tex]Cancel out the common factor [tex](cosx+sinx)[/tex].
[tex]\bold{\frac{(cosx-sinx)}{(sinx)}}[/tex]Since this is the furthest simplified that the left side can be manipulated, let's see if can try to manipulate the right side to also look like [tex]\frac{(cosx-sinx)}{(sinx)}[/tex].
Start by expressing [tex]cotx-1[/tex] with [tex]sinx[/tex] and [tex]cosx[/tex], since we know that cotangent is simply [tex]\frac{x}{y} \rightarrow\frac{cosx}{sinx}[/tex].
[tex]\frac{cosx}{sinx}-1[/tex]We can simplify this expression to look like our expression we found by manipulating the left side [tex](\frac{(cosx-sinx)}{(sinx)})[/tex] by making the 1 have a common denominator of [tex]sinx[/tex].
To do this, multiply 1 by [tex]\frac{sinx}{sinx}[/tex]. Now the expression should look like:
[tex]\frac{cosx}{sinx}-\frac{sinx}{sinx}[/tex]Since they have a common denominator we can write the expression under one fraction, like so:
[tex]\bold{\frac{cosx-sinx}{sinx}}[/tex]This looks exactly the same as what we manipulated the left side to be [tex](\frac{(cosx-sinx)}{(sinx)})[/tex], just without parentheses. I put both expressions in bold. Therefore, this identity proves to be true as we just proved it.

Step-by-step explanation:
Write an equation that represents the volume V as a function of the height h
Answer:
h=V/b
Step-by-step explanation:
The volume V can be represented as a function of height h by the equations V = lwh for a rectangular prism or V = πr²h for a cylinder. If other dimensions are constants, this can be simplified to V=k*h, where k represents the base area.
Explanation:To represent the volume V as a function of the height h, we typically consider the volume of a rectangular or cylindrical shape. The volume V of a rectangular prism is given by the formula V = lwh, where l is the length, w is the width, and h is the height. If we consider a cylinder, the volume is given by the equation V = πr²h, where r is the radius of the base circle and h is the height. However, if we simplify this formula assuming only the height can vary and all other dimensions are constants, the function could be simplified to V=k*h, where k represents the area of the base.

What is the solution to the system of equations y=-3×-2 5×+2y=15
Answer: x = - 19
y = 55
Step-by-step explanation:
y = - 3x - 2 (1)
5x + 2y = 15 (2)
substitute y = - 3x - 2 into equation (2)
equation (2) becomes
5x + 2 (-3x - 2) = 15
5x + ( - 6x - 4) = 15
opening the bracket
5x - 6x - 4 = 15
collecting like terms
5x - 6x = 15 + 4
-x = 19
x = - 19
substituting x = - 19 into equation 1
y = - 3x - 2
y = - 3 (-19) - 2
y = 57- 2
y = 55

LaTanya says that the growth factor of f(x) = 100(1.25) is 25%. What mistake did LaTanya make?
Answer:
The first error consists in the multiplication of f (x) = 100 * (1.25), the value she mentions is incorrect since it is 125.
It would be a 125% increase really.
In order for LaTanya's phrase to have no error she had to mention that it was a 25% increase over the original amount, in this way, the phrase would make sense and be valid.
Answer:
LaTanya confused growth factor with growth rate. The growth factor is 1.25. The growth rate is 25%.
Step-by-step explanation:
In the exponential growth model,
f(x)=a(1+r)x
a is the inital amount, r is the growth rate, and (1+r) is the growth factor. Hence, the growth factor of the given function is 1.25.
Find the value of 6+x when x = 15.
Answer:
Step-by-step explanation:
Given the function f(x)=6+x
F(x) is dependent on x,
When x=1
f(x)=6+x
f(x)=6+1,
f(x)=7
When x=2
f(x)=6+x
f(x)=6+2
f(x)=8.
This will continue like this till we get to x=15
So when x=15
We will substitute x=15 into the function f(x)
f(x)=6+x
f(x)=6+15
f(x)=21
Then, the answer is 21.
Answer: 17

The question refers to numerical approximation methods used for integration: the Trapezoidal, Midpoint, and Simpson's Rules. Answers for specific n-values and error calculations require a calculator or programming tool and are not provided here. The processes, however, involve application of respective formulae and comparison of approximations against the desired accuracy level.
Explanation:Solution:
The question is related to approximating the value of an integral using numerical methods, specifically using the Trapezoidal Rule (Tn), Midpoint Rule (Mn), and Simpson's Rule (Sn). Additionally, it asks about the corresponding estimation errors which are defined as differences between the true integral value and the approximations.
Part (a)
To find T10, M10, and S10 for ∫₀π (21 sin x) dx, we would use respective formulae. Unfortunately, without a calculator or computational tool, it's not practical to perform these calculations here in this answer.
Part (b)
The actual errors ET, EM, and ES compare to the theoretical error bounds given by the respective theorems for each rule. Again, without the approximated values from part (a), we cannot calculate these errors.
Part (c)
Choosing n so that the approximations are accurate to within 0.00001 is a trial and error process where you start with n and continue to increase it until the approximation is within the desired accuracy. This typically requires use of a computational tool or programming.
Please note, these answers can vary depending on the specific constants and functions used in the integration.

At the zoo, the ratio of mammals to reptiles is 4:3. There are 20 mammals in the zoo.
(a) How many reptiles are in the zoo?
(b) If the zoo adds 12 more mammals to its collection, how many more reptiles will they have to add to keep the ratio the same?
(c) A zoo in a different city has a ratio of mammals to reptiles of 6:5. Which zoo has the larger ratio of mammals to reptiles?
Thank you!
Answer: im not sure but a)15 B)24 c)zoo in a different city
Step-by-step explanation:
There are 15 reptiles in the zoo. To keep the ratio 4:3, if the zoo adds 12 more mammals, they will need to add 9 more reptiles. The first zoo has a larger ratio of mammals to reptiles (4:3) compared to the second zoo (6:5).
To answer the question, let's solve each part step by step:
Given the ratio of mammals to reptiles is 4:3 and there are 20 mammals, we can set up a proportion to find the number of reptilesIf the zoo adds 12 more mammals, to keep the same ratio of 4:3, we calculate the number of reptiles to add. We can find this by multiplying the 12 additional mammals by 3/4, which results in 9 more reptiles.To compare the ratios of the zoos, we can turn them into comparable fractions: 4/3 for the first zoo and 6/5 for the second zoo. By finding a common denominator or comparing their cross-multiplication products, we can determine which ratio represents a larger number of mammals to reptiles. Here, 4/3 is larger than 6/5, so the first zoo has a larger ratio of mammals to reptiles. This can be confirmed by cross multiplication: 4*5=20 and 6*3=18, since 20 is greater than 18, the first zoo has a larger ratio.Can there be two modes in a data set?? for example 2,5,6,7,9,9,11,11,12,13
Final answer:
Yes, a data set can have two modes, which occurs when two different values appear with equal and highest frequency, making the set bimodal.
Explanation:
Yes, there can be two modes in a data set. The mode is the most frequent value or values in a set of data. When a data set has exactly two modes, it is called bimodal. This phenomenon occurs when two different numbers appear with equal frequency and more often than any other numbers in a set. For example, in the data set 2,5,6,7,9,9,11,11,12,13, both 9 and 11 appear twice and more frequently than any other values, making them both modes of the data set.
