Rock Particles are categorized into 6 types:
Trina is buying favors for a birthday party. All of the party favors cost more than $13. What is the least expensive the party favors could be?
The least expensive will be the lowest cost among the cost greater than $13.
i.e $13.5
If the cost of the favors is:
$13.5 < $14 < $15 < $20
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
All of the party favors cost more than $13.
This means,
Cost = x
x > 13
Now,
If the following are the cost of the favors:
$13.5, $14, $15, and $20
The least expensive will be the lowest cost among the cost greater than $13.
i.e $13.5
13.5 < 14 < 15 < 20
Thus,
The least expensive will be the lowest cost among the cost greater than $13.

What is an increasing function?If the slope of a function is continuously increasing or constant in an interval, the function is known as an increasing function.
Let us assume \(f(x)=ab^x+c\)
at x=0, f(0)=-10
So, \(-10=a+c\)
Similarly, by satisfying the above table in the f(x)
\(f(x)=-\frac{33}{5} (\frac{1}{11} )^x-\frac{17}{5}\)
\(f'(x) > 0\)
So we can say that f(x) is an increasing function.
\(g(x)=-18(\frac{1}{3} )^x+2\)
\(g'(x)=-18(\frac{1}{3} )^xln(\frac{1}{3} )\)
\(ln\frac{1}{3} < 0\)
So, \(g'(x) > 0\)
So, g(x) is an increasing function.
For any x∈f(x) and x∈g(x) \(g'(x) > f'(x)\)
So, g increases at a faster average rate
Thus, Both functions are increasing, but function g increases at a faster average rate.

What is the volume and surface area of this cone?
Answer:
Volume = 261.8 cm³
Surface area = 254.2 cm²
Step-by-step explanation:
To calculate the volume of the cone, we have to use the following formula:
\(\boxed{V = \frac{1}{3} \pi r^2 h}\),
where:
V ⇒ volume
r ⇒ radius = 5 cm
h ⇒ height = 10 cm
Using the above formula and the provided measures, we get:
V = \(\frac{1}{3}\) × π × (5)² × 10
= \(\frac{1}{3}\) × π × 25 × 10
= 261.8 cm³
In order to calculate the surface area of the cone, we have to use the following formula:
\(\boxed{SA = \pi r^2 + \pi r l}\)
where:
SA ⇒ surface area
r ⇒ radius = 5 cm
l ⇒ slant length = \(\sqrt{r^2+h^2}\) = \(\sqrt{5^2+10^2}\) = 5√5 cm
Using the formula,
SA = π × (5)² + π × 5 × 5√5
= π × 25 + π × 25√5
= 254.2 cm²

tyler rolled six 4s how close can he get to 1 without going over
Tyler would have an average roll of 5 which is only the closest he can get to 1 without going over if he is using standard six-sided dice.
How do we know this?We have the scenario that if Tyler has rolled six 4s, the highest possible sum he can achieve is 24 (6 x 4).
Tyler should aim to roll the remaining dice as low as possible, for him get as close as possible to 1 without going over.
It is assumed that Tyler is using standard six-sided dice, the lowest number he can roll on a single die is 1. So for him to get as close to 1 as possible, Tyler should roll six 1s on the remaining dice.
In conclusion, this would give Tyler a total of 30 (24 + 6) and an average roll of 5.

A box with a square base is taller than its wide. In order to send the box through the U.S. mail, the height of the box and the perimeter of the base can sum to no more than 108 inches. What is the maximum volume for such a box
The maximum volume for a box with a square base that is taller than its width, given the constraint that the sum of the height and the perimeter of the base cannot exceed 108 inches, would occur when the box is a cube, resulting in a maximum volume of 36,000 cubic inches.
To find the maximum volume for a box with a square base, subject to the constraint that the height of the box and the perimeter of the base can sum to no more than 108 inches, we can use optimization techniques.
Let's denote the side length of the square base as "s" and the height of the box as "h".
Since the box is taller than it is wide, we have h > s.
The perimeter of the base is given by 4s, and we know that the sum of the height and the perimeter of the base must be less than or equal to 108 inches.
Therefore, we have the inequality h + 4s ≤ 108.
To find the maximum volume, we need to maximize the function V = s² \(\times\)h.
Since h > s, we can express h in terms of s as h = s + k, where k is a positive constant.
Substituting this expression into the inequality, we have s + k + 4s ≤ 108.
Simplifying the inequality, we get 5s + k ≤ 108.
Now, we can express k in terms of s as k = 108 - 5s.
Substituting this expression back into the equation for the volume, we have V = s² * (s + (108 - 5s)).
Simplifying further, we have V = s³ + 108s² - 5s³.
To find the maximum volume, we take the derivative of V with respect to s and set it equal to zero: dV/ds = 3s² + 216s - 5 = 0.
Solving this equation, we find the value of s that maximizes the volume.
Once we have the value of s, we can substitute it back into the expression for h = s + k to find the corresponding height.
Finally, we can calculate the maximum volume using V = s² * h.

A bouncing toy reaches a height of 64 inches at its first peak, 48 inches at its second peak, and 36 inches at its third peak. Which explicit function represents the geometric sequence of the heights of the toy?
f(x) = 48(Five-sixths) Superscript x minus 1
f(x) = 48(three-fourths) Superscript x minus 1
f(x) = 64(three-fourths) Superscript x minus 1
f(x) = 64(Five-sixths) Superscript x minus 1
Answer:
The correct option is;
f(x) = 64(three-fourths)Superscript x minus 1
Step-by-step explanation:
The first peak height that the bouncing toy reaches = 64 inches
The second peak height that the bouncing toy reaches = 48 inches
The third peak height that the bouncing toy reaches = 36 inches
Therefore, given that the sequence has a common ratio, r = 48/64 = 36/48 = 3/4
The first term of the sequence, a = The first peak height reached = 64
The xth term of the geometric sequence with general form, xth term = ar⁽ˣ⁻¹⁾
The xth term of the geometric sequence, f(x), is therefore, given as follows;
\(f(x) = 64 \times \left(\dfrac{3}{4} \right) ^{(x - 1)}\)
The correct option is;
f(x) = 64(three-fourths)Superscript x minus 1
Step-by-step explanation:
The first peak height that the bouncing toy reaches = 64 inches
The second peak height that the bouncing toy reaches = 48 inches
The third peak height that the bouncing toy reaches = 36 inches
Therefore, given that the sequence has a common ratio, r = 48/64 = 36/48 = 3/4
The first term of the sequence, a = The first peak height reached = 64
The xth term of the geometric sequence with general form, xth term = ar⁽ˣ⁻¹⁾
The xth term of the geometric sequence, f(x), is therefore the correct answer is C
for which wahcs of real k is the differential equation (aos(3x)+ky−y 2
+2)dx+(−2yx+3x−1)dy=0 exact?
The value of k for which the given differential equation is exact is k = (9-a^2)/4, where a is any real number.
To determine the values of k for which the given differential equation is exact, we need to check if it satisfies the condition of exactness, which is given by:
∂(aos(3x)+ky−y^2+2)/∂y = ∂(−2yx+3x−1)/∂x
Differentiating the first term with respect to y, we get:
∂(aos(3x)+ky−y^2+2)/∂y = a
Similarly, differentiating the second term with respect to x, we get:
∂(−2yx+3x−1)/∂x = −2y+3
Equating these two expressions, we get:
a = −2y + 3
Solving for y, we get:
y = (3-a)/2
Substituting this value of y in the original differential equation and simplifying, we get:
[(3-a)os(3x)+k/4-(9-a^2)/4]dx + [(a-3)x-1]dy = 0
For this equation to be exact, we need:
∂[(3-a)os(3x)+k/4-(9-a^2)/4]/∂y = ∂[(a-3)x-1]/∂x
Differentiating the first term with respect to y, we get:
∂[(3-a)os(3x)+k/4-(9-a^2)/4]/∂y = 0
Similarly, differentiating the second term with respect to x, we get:
∂[(a-3)x-1]/∂x = a - 3
Equating these two expressions, we get:
a - 3 = 0

The 33rd percentile is 75.4.
Percentile is defined as the value below which a given percentage falls under. The percentile formula is used when we need to compare the exact values or numbers over the other numbers from the given data i.e. the accuracy of the number.
To find the percentile, here are a few steps to use the percentile formula. If q is any number between zero and hundred, the qth percentile is a value that divides the data into two parts i.e the lowest part contains the q percent of the data and the rest of the data is the upper part.
We find the rank.
Rank = Percentile ÷ 100
Rank = 33 ÷ 100 = 0.33
So, the rank is 0.33.
Using the percentile formula,
Percentile = Rank × Total number of the data set
Percentile = 0.33 × 117
Percentile = 38.61 ≅ 39
Now, counting 39 values from left to right we reach 75.4, and we can say that all the values below 75.4 will come under the 33rd percentile. In other words, 33% of the values are below 75.4.
Therefore, the 33rd percentile is 75.4.

Which of the following statements is
false?
A. -1 is a perfect square.
B. 1 is a perfect cube.
C.
1 is a perfect square.
D. √1 is rational.
find each of these values. a) (−133 mod 23 261 mod 23) mod 23 b) (457 mod 23 ⋅ 182 mod 23) mod 23
The value of (a) is (−133 mod 23 261 mod 23) mod 23 equals 20 and the value of (b) is (457 mod 23 ⋅ 182 mod 23) mod 23 equals 16.
a) To calculate (−133 mod 23 261 mod 23) mod 23, we start by evaluating the innermost parentheses.
−133 mod 23 equals -10, because -133 divided by 23 gives a quotient of -5 with a remainder of -10.
Similarly, 261 mod 23 equals 7, because 261 divided by 23 gives a quotient of 11 with a remainder of 7.
Now, we substitute these values into the expression:
(-10 mod 23 7 mod 23) mod 23.
Next, we evaluate the outermost parentheses:
-10 mod 23 equals -10, and 7 mod 23 equals 7.
Finally, we substitute these values back into the expression:
(-10 mod 23 7 mod 23) mod 23 equals (-10 7) mod 23.
Calculating the subtraction first, we get -3 mod 23.
To ensure the result is positive, we add 23 to -3, giving us 20 mod 23.
Therefore, (−133 mod 23 261 mod 23) mod 23 equals 20.
b) To find (457 mod 23 ⋅ 182 mod 23) mod 23, we begin by evaluating the innermost parentheses.
457 mod 23 equals 4, as 457 divided by 23 gives a quotient of 19 with a remainder of 4.
Similarly, 182 mod 23 equals 4, because 182 divided by 23 gives a quotient of 7 with a remainder of 4.
Now, we substitute these values into the expression:
(4 ⋅ 4) mod 23.
Multiplying 4 by 4 gives us 16.
Finally, we substitute this value back into the expression:
(4 ⋅ 4) mod 23 equals 16 mod 23.
Therefore, (457 mod 23 ⋅ 182 mod 23) mod 23 equals 16.
