The next three numbers in sequence are 22, 32 and 44
Solution:
Given sequence is:
2, 4, 8, 14, ...
We have to find the next 3 numbers in sequence
Let us understand the logic used in this sequence
[tex]First\ term = 1^2 -1+2 = 1 + 1 = 2\\\\Second\ term = 2^2 -2 + 2 = 4\\\\Third\ term = 3^2 - 3 + 2 = 9 - 1 = 8\\\\Fourth\ term = 4^2 -4 + 2 = 16-2 = 14[/tex]
Thus the formula used is:
[tex]a_n = n^2 - n +2[/tex]
Where, "n" is the location of term in sequence
To find the next three terms:
[tex]Fifth\ term = 5^2 - 5 + 2 = 25 - 3 = 22\\\\Sixth\ term = 6^2 - 6 + 2 = 36 - 4 = 32\\\\Seventh\ term = 7^2 -7 + 2 = 49 - 5 = 44[/tex]
Thus the next three numbers in sequence are 22, 32 and 44
FLAGPOLE Julie is 6 feet tall. If she stands 15 feet from the flagpole and holds a cardboard square, the edges of the square line up with the top and bottom of the flagpole. Approximate the height of the flagpole
Answer:
44 ft
Step-by-step explanation:
Given: Julie is 6 feet tall
She stands 15 feet from the flagpole.
The edges of the square line up with the top and bottom of the flagpole.
Lets assume the height of flagpole be "h".
As given, the edges of the square line up with the top and bottom of the flagpole.
∴ Angle and base of triangle are same then ratio of corresponding sides are also equal.
Now, finding the height of flagpole by using tangent rule.
we know, [tex]tan\theta= \frac{Opposite}{adjacent}[/tex]
Remember, both the angle are equal.
∴ Ratio of opposite and adjacent leg for both right angle triangle= [tex]\frac{6}{15} : \frac{h-6}{15}[/tex]
We can put it; [tex]\frac{6}{15} = \frac{15}{h-6}[/tex]
Solving the equation now
⇒ [tex]\frac{6}{15} = \frac{15}{h-6}[/tex]
Multiplying both side by 15
⇒[tex]6 = \frac{15\times 15}{h-6}[/tex]
Multiplying both side by (h-6)
⇒ [tex]6\times (h-6) = 15\times 15[/tex]
Distributive property of multiplication
⇒ [tex]6h-36= 225[/tex]
Adding both side by 36
⇒[tex]6h= 225+36[/tex]
Dividing both side by 6
⇒[tex]h= \frac{261}{6}[/tex]
∴ [tex]h= 43.5\ feet[/tex] [tex]\approx 44 feet[/tex]
Hence, the height of flagpole is 44 feet.
Final answer:
To approximate the height of a flagpole given that Julie, who is 6 feet tall, lines up a cardboard square with the top and bottom of the flagpole while standing 15 feet away, we can use the principles of similar triangles. This results in a calculation showing that the flagpole is approximately 6 feet tall, the same as Julie's height.
Explanation:
The height of the flagpole can be approximated using similar triangles. Julie is 6 feet tall and stands 15 feet from the flagpole. Using the cardboard square, we understand that the triangle formed by Julie and her shadow is similar to the triangle formed by the flagpole and its shadow. Therefore, we can set up a proportion:
Julie's height / Julie's distance from flagpole = Flagpole's height / Flagpole's distance from cardboard.
If we assume that the cardboard square is held adjacent to Julie, the flagpole's distance from the cardboard is also 15 feet. The proportion simplifies to:
6 feet / 15 feet = Flagpole's height / 15 feet
Cross-multiplying to solve for the flagpole's height gives us:
Flagpole's height = 6 feet × (15 feet / 15 feet) = 6 feet
Therefore, the flagpole is approximately 6 feet tall.
Where will her cut be located? Round to the nearest tenth. Genevieve is cutting a 60-inch piece of ribbon into a ratio of 2:3. Since 2 inches are frayed at one end of the ribbon, she will need to start 2 inches in. This is indicated as 2 on the number line. 25.2 in. 29.4 in. 35.1 in. 40.7 in.
Answer:
25.2 in
Step-by-step explanation:
The short piece will have a length that is 2/(2+3) = 2/5 of the entire usable length. The usable length is 60-2 = 58 inches long, so the cut will be ...
(2/5)(58 in) = 23 1/5 in
from the beginning of the usable part. Since the usable part of the ribbon starts 2 inches in, the cut will be 23 1/5 + 2 = 25 1/5 inches from the frayed end of the ribbon.

Are 11dx2 and 22d not equivalent or equivalent?
Are 8m+(9m-1) and 8m-8 not equivalent or equivalent?
Please help me...
(1) 10(e + 0.5)g
Using distributive property, a × (b + c) = a × b + a × c
10(e + 0.5)g = 10 eg + 10 × 0.5g
Therefore, 10(e + 0.5g) and 10e + 5g are not equivalent.
(2) 6(p + q)
Using distributive property,
6(p + q) = 6p + 6q
Therefore, 6(p + q) and 6p + q are not equivalent.
(3) 7y – 15 + 2y
Using commutative property, a + b = b + a
7y – 15 + 2y = 7y + 2y – 15
= 9y – 15
Therefore 7y – 15 + 2y and 9y – 15 are equivalent.
(4) 1 + (8r + 9)
Using associative property, a + (b + c) = (a + b) + c
1 + (8r + 9) = (1 + 9) + 8r
= 10 + 8r
= (2 + 8) + 8r
Therefore 1 + (8r + 9) and (2 + 8) + 8r are equivalent.
(5) 0 × 11 + 5n
Using multiplicative identity property: a × 0 = 0
0 × 11 + 5n = 0 + 5n
= 5n
Therefore, 0 × 11 + 5n and 5n are equivalent.
(6) 16s – 4 + s
Using associative property, a + (b + c) = (a + b) + c
16s – 4 + s = 16s + s – 4
= 17s – 4
Therefore, 16s – 4 + s and 12s not equivalent.
(7) 11d × 2 = 22d
Therefore, 11d × 2 and 22d are equivalent.
(8) 8m + (9m – 1)
Using associative property, a + (b + c) = (a + b) + c
8m + (9m – 1) = (8m + 9m) – 1
= 17m – 1
Therefore, 8m + (9m – 1) and 8m – 8 not equivalent.

Eva and her children went into a restaurant and where they sell hotdogs for $5 each and tacos for $2.50 each. Eva has $30 to spend and must buy at least 7 hotdogs and tacos altogether. If Eva decided to buy 2 hotdogs, determine the maximum number of tacos that she could buy.
Answer: 8 tacos
Step-by-step explanation: 2 hotdogs are $10 as they are $5 each. Tacos are $2.50 each. $2.50 x 8 equals $20. $20 + 10 = $30. Eva can buy 8 tacos.
After buying 2 hotdogs with $10, Eva will have $20 left. With the remaining $20, she can buy a maximum of 8 tacos at $2.50 each.
Explanation:Since Eva is determined to buy 2 hotdogs at $5 each, she will spend $10 on hotdogs. She has a total of $30 to spend, meaning she will have $20 left after purchasing the hotdogs. Tacos cost $2.50 each. Therefore, with the remaining $20, Eva can afford to buy a maximum of 8 tacos (since $20 divided by $2.50 equals 8). This will also meet the condition of purchasing at least 7 hotdogs and tacos in total.

how would I find x?
Step-by-step explanation:
In the question figure,
∠ 1 = 115 °, ∠ 2 = 115 °, ∠ 3 = 120 °, ∠ 4 = 14x °, ∠ 5 = 133 °, ∠ 6 = 167 °, ∠ 7 = 138° and ∠ 8 = 18x °
To find, the value of x = ?
We know that,
The sum of all angles of heptagon = 1080°
∴ ∠ 1 + ∠ 2 + ∠ 3 + ∠ 4 + ∠ 5 + ∠ 6 + ∠ 7 + ∠ 8 = 1080°
⇒ 115 ° + 115 ° + 120 ° + 14x ° + 133 ° + 167 ° + 138° + 18x ° = 1080°
⇒ 32x ° + 788° = 1080°
⇒ 32x ° = 1080° - 788° = 292°
⇒ x ° = 9.125°
∴ x ° = 9.125°

the numerator of a fraction is 12 the gcf witch stand for great common factor of the numerator and denominator is 4. what is the denominator
Answer:
16.
Step-by-step explanation:
The denominator could be 16.
The GCF of 12 and 16 is 4.
Final answer:
The denominator of the fraction with a numerator of 12 and a GCF of 4 with the denominator is 12. You divide the numerator by the GCF and then multiply the result by the GCF to get the denominator.
Explanation:
The student is asking for the denominator of a fraction when the numerator is 12 and the greatest common factor (GCF) of the numerator and the denominator is 4. To find the denominator, you would divide the numerator (12) by the GCF (4). This gives us 12 ÷ 4, which equals 3. Therefore, the denominator of the fraction must be a number that when divided by the GCF (4) will give us a quotient of 3. Since the denominator is 4 times larger than this quotient, we multiply 3 by 4 to find the denominator. Therefore, the denominator is 3 × 4, which equals 12.
A certain television is advertised as a 29-inch TV (the diagonal length). If the width of
the TV is 20 inches, how many inches tall is the TV?
Answer:
21 inches
Step-by-step explanation:
refer to attached graphics
we can find the height by the Pythagorean theorem.
diagonal² = width² + height²
height² = diagonal² - width²
we are given that diagonal = 29" and width = 20", hence
height² = 29² - 20²
height² = 841 - 400
height² = 441
height = √441 = 21 inches
Convert the complex number z = -7 - 8i from rectangular form to polar form.
The polar form of z = -7 - 8i is:
z = 3√13 (cos 230.2° + i sin 230.2°)
Converting -7 - 8i to polar form:
The rectangular form of a complex number is given by z = a + bi, where a is the real part and b is the imaginary part. In this case, a = -7 and b = -8.
The polar form of a complex number is given by z = r(cos θ + i sin θ), where:
r is the modulus (or absolute value), which represents the distance of the complex number from the origin in the complex plane.
θ is the argument (or angle), which represents the direction of the complex number relative to the positive real axis.
1. Finding modulus (r):
r = √(a² + b²) = √((-7)² + (-8)²) = √(113) = √(13 * 9) = √13 * 3 (using factorization and perfect squares)
Therefore, r = 3√13.
2. Finding argument (θ):
θ = arctan(b/a) = arctan((-8)/(-7)) ≈ 50.2° (using the arctangent function on a calculator). However, this only gives one possible angle for the complex number.
Note: The arctangent function typically outputs values between -90° and 90°, which corresponds to Quadrant 1 or 4 in the complex plane. Since -7 - 8i lies in Quadrant 3, we need to add 180° to get the correct angle:
θ = 50.2° + 180° = 230.2°
Therefore, the polar form of z = -7 - 8i is:
z = 3√13 (cos 230.2° + i sin 230.2°)
The volume of a box is 39.375 inches³. What is the volume of the box if it is scaled down by a factor of 1/10?
The volume of scaled object is 0.039375 cubic inches
Solution:
Given that,
Volume of box = 39.375 cubic inches
Scaled down by a factor = [tex]\frac{1}{10}[/tex]
The volume of a scaled object will be equal to the volume of object times scale factor cubed
Therefore,
Volume of scaled object = Volume of box x scale factor cubed
[tex]Volume\ of\ scaled\ object = 39.375 \times (\frac{1}{10})^3\\\\Volume\ of\ scaled\ object = 39.375 \times \frac{1}{1000}\\\\Volume\ of\ scaled\ object = 0.039375[/tex]
Thus volume of scaled object is 0.039375 cubic inches
One positive number is three larger than another positive number. If sixteen times the reciprocal of the smaller number is added to nine times the reciprocal of the larger number, the sum is one. Find the two number.
Answer: = [tex]\frac{25+\sqrt{949} }{6}[/tex] and y = \frac{25+\sqrt{949} }{6} - 3.
Step-by-step explanation:
Take x as the larger number and y as the smaller number.
x + 3 = y
[tex]\frac{16}{y}[/tex]+ [tex]\frac{9}{x}[/tex] = 1
Substitute x + 3 for y in the second equation.
[tex]\frac{16}{x+3}[/tex]+ [tex]\frac{9}{x}[/tex] = 1
Make a common denominator.
[tex]\frac{16(x) + 9(x+3)}{(x+3)(x)} =1[/tex]
Simplify and get rid of that fraction.
[tex]16x + 9x + 27 = x^{2} + 3x[/tex]
[tex]x^{2} + 3x - 25x - 27 = 0[/tex]
[tex]x^{2} -22x - 27 = 0[/tex]
By quadratic formula (and because they must be positive), x = [tex]\frac{25+\sqrt{949} }{6}[/tex] and then y = \frac{25+\sqrt{949} }{6} - 3.
To solve for the two positive numbers, we can set up an equation and solve for x.
Explanation:Let's call the smaller number x and the larger number x + 3.
From the given information, we can write the following equation:
16(1/x) + 9(1/(x + 3)) = 1
To solve this equation, we can find a common denominator and then simplify:
16(x + 3)/(x(x + 3)) + 9x/(x(x + 3)) = 1
After simplifying and solving for x, we find that the smaller number is 4 and the larger number is 7.

Every day, Bert spends an hour commuting to and from his office, driving at an average speed of 50 mph and taking the same route each way. How far does Bert live from his office?
When speed and time are known, distance can be calculated using the formula 'distance = speed x time'. Given Bert's speed of 50 mph and travel time of 0.5 hours each way, the distance from his home to the office is calculated to be 25 miles.
Explanation:The subject of this problem is fundamentally about understanding the relationship between speed, time, and distance. In this particular case, Bert is spending a total of an hour commuting to and from office. However, this total time includes both the journey to work and the journey back home so each journey takes half an hour or 0.5 hours. Given that his average speed is 50 mph, we can calculate the distance he travels one way using the formula "Distance = Speed x Time."
So, for Bert:
Distance = 50 mph x 0.5 hours = 25 miles

Which of the following equations can be a harmonic on a string that is 10 cm long? Select all that apply. (three correct answers)
A.) y=2sin(pi/5 x)
B.) y=2sin(2pi/7 x)
C.) y=2sin(pi/10 x)
D.) y=2sin(10pi x)
E.) y=2sin (5/2pi x)
Answer:
The options are: A, C and D
Step-by-step explanation:
The sine wave has a general form : y = A sin (BX)
Where A is the amplitude and B = 2π/period
So, we will check which of the options will be a harmonic on a string that is 10 cm long.
A.) y=2sin(pi/5 x)
B = π/5 ⇒ period = 2π/B = 2π ÷ π/5 = 2π * 5/π = 10
So, one cycle of y=2sin(pi/5 x) will be a harmonic on a string that is 10 cm long.
B.) y=2sin(2pi/7 x)
B = 2π/7 ⇒ period = 2π/B = 2π ÷ 2π/7 = 7
C.) y=2sin(pi/10 x)
B = π/10 ⇒ period = 2π/B = 2π ÷ π/10 = 20 = 2 * 10
So, half a cycle of y=2sin(pi/10 x) will be a harmonic on a string that is 10 cm long.
D.) y=2sin(10pi x)
B = 10π ⇒ period = 2π/B = 2π ÷ 10π = 1/5 = 10/50
So, 50 cycles of y=2sin(10pi x) will be a harmonic on a string that is 10 cm long.
E.) y=2sin (5/2pi x)
B = 5/2π ⇒ period = 2π/B = 2π ÷ (5/2π) = 4π²/5
So, options A, C and D can be a harmonic on a string that is 10 cm long.
Answer:
A. y=2sin(pi/5x)

Step-by-step explanation:
In circle A:
∠BAE ≅ ∠DAELine segments A B, A E, and A D are radiiLines are drawn from point B to point E and from point E to point D to form secants B E and E DThe length of B E is 3 x minus 24 and the length of E D is x + 10We need to find the length of BE
∵ AB and AD are radii in circle A
∴ AB ≅ AD
In Δs EAB and EAD
∵ ∠BAE ≅ ∠DAE ⇒ given
∵ AB = AD ⇒ proved
∵ EA = EA ⇒ common side in the two triangles
- Two triangles have two corresponding sides equal and the
including angles between them are equal, then the two
triangles are congruent by SAS postulate of congruence
∴ Δ EAB ≅ Δ EAD ⇒ SAS postulate of congruence
By using the result of congruence
∴ EB ≅ ED
∵ EB = 3 x - 24
∵ ED = x + 10
- Equate the two expressions to find x
∴ 3 x - 24 = x + 10
- Add 24 to both sides
∴ 3 x = x + 34
- Subtract x from both sides
∴ 2 x = 34
- Divide both sides by 2
∴ x = 17
Substitute the value of x in the expression of the length of BE to find its length
∵ BE = 3 x - 24
∵ x = 17
∴ BE = 3(17) - 24
∴ BE = 51 - 24
∴ BE = 27

Where n represents the total number of items, and r represents the number of items being chosen at a time
Let us first calculate 5 baseball players from 12 baseball players
Here, n = 12 and r = 5
[tex]\begin{array}{l}{12 C_{5}=\frac{12 !}{5 !(12-5) !}} \\\\{12 C_{5}=\frac{12 !}{5 ! \times 7 !}}\end{array}[/tex]
For a number n, the factorial of n can be written as:
[tex]n !=n \times(n-1) \times(n-2) \times \ldots . \times 2 \times 1[/tex]
Therefore,
[tex]\begin{aligned}12 C_{5} &=\frac{12 \times 11 \times 10 \times \ldots \ldots \times 2 \times 1}{5 \times 4 \times 3 \times 2 \times 1 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1} \\\\12 C_{5} &=\frac{12 \times 11 \times 10 \times 9 \times 8}{5 \times 4 \times 3 \times 2} \\\\12 C_{5} &=792\end{aligned}[/tex]
Similarly, 4 basketball players be selected 13 basketball players
n = 13 and r = 4
Similarly we get,
[tex]\begin{aligned}&13 C_{4}=\frac{13 !}{4 !(13-4) !}\\\\&13 C_{4}=\frac{13 !}{4 ! \times 9 !}\end{aligned}[/tex]
[tex]13C_4 = 715[/tex]
Thus total number of ways are:
[tex]12C_5 + 13C_4 = 792 + 715 = 1507[/tex]
Thus there are 1507 different ways
To determine the number of ways to select 5 baseball players from 12, and 4 basketball players from 13, we use the combination formula for both and multiply the results, applying the Counting Principle.
Explanation:The question asks how many different ways can 5 baseball players and 4 basketball players be selected from 12 baseball players and 13 basketball players. This is a problem of combinatorics, specifically the use of combinations, since the order of selection does not matter.
To find the number of ways to select the baseball players, we use the combination formula C(n, k) = n! / (k! * (n-k)!), where 'n' is the total number to choose from, 'k' is the number to choose, and '!' denotes factorial. For the 5 baseball players from 12, it is C(12, 5).
For the basketball players, it's C(13, 4), as we are choosing 4 out of 13. To find the total number of ways to form the group, we multiply these two values together, because each combination of baseball players can be paired with each combination of basketball players, which is an example of the Counting Principle.
So, the calculation is C(12, 5) * C(13, 4).

C. p + 11
D. 8p + 1
E. 7p – 1
Answer:
the anwser is a
Step-by-step explanation:
The expression represents the total number of tomato plants is [tex]\rm p + (3p - 5) + (4p + 6)[/tex].
Given that
Lauryn grew p tomato plants.
The Padma grew 5 fewer than 3 times the number Lauryn grew.
Kent grew 6 more than 4 times the number Lauryn grew.
We have to determine
Choose an expression and a simplified expression to represent the total number of tomato plants that Lauryn, Padma, and Kent grew.
According to the question
Let the number of tomato plants be p.
Lauryn grew p tomato plants.
[tex]\rm = p[/tex]
The Padma grew 5 fewer than 3 times the number Lauryn grew.
[tex]\rm= 3p-5[/tex]
Kent grew 6 more than 4 times the number Lauryn grew.
[tex]\rm = 4p+6[/tex]
Therefore,
An expression to represent the total number of tomato plants = Lauryn + Padma + and Kent grew.
[tex]\rm p + (5 - 3p) + (6 + 4p)[/tex]
Hence, the expression represents the total number of tomato plants is [tex]\rm p + (3p - 5) + (4p + 6)[/tex].
