ANSWER
[tex]x = - \frac{2\pi}{3} [/tex]
EXPLANATION
The given function has equation
[tex]y = \tan( \frac{3}{4}x) [/tex]
This can be rewritten as
[tex]y = \frac{ \sin( \frac{3}{4}x ) } { \cos(\frac{3}{4}x )}[/tex]
The asymptote occurs at:
[tex]\cos(\frac{3}{4}x ) = 0[/tex]
This implies that,
[tex] \frac{3}{4} x = \frac{ \pi}{2} [/tex]
[tex]x = \frac{ \pi}{2} \times \frac{4}{3} [/tex]
[tex]x = \frac{2\pi}{3} [/tex]
Or
[tex]\frac{3}{4} x = - \frac{ \pi}{2} [/tex]
[tex]x = \frac{ - \pi}{2} \times \frac{4}{3} [/tex]
[tex]x = - \frac{2\pi}{3} [/tex]

A fireplace contains 72 bricks along its bottom row. If each row above decreases by 6 bricks, what is the function that shows the bricks on the 14th row?
Answer:
[tex]a_n=78-6n[/tex]
[tex]a_{14}=78-6(14)[/tex]
Step-by-step explanation:
To solve this, we are using the formula for the nth term of an arithmetic progression:
[tex]a_n=a_1+(n-1)d[/tex]
where
[tex]a_1[/tex] is the first term of the progression
[tex]d[/tex] is the difference
[tex]n[/tex] is position of the term in the progression
We know for our problem that the bottom row contains 72 bricks, so [tex]a_1=72[/tex]. We also know that each row above decreases by 6 bricks, so the difference is -6 ([tex]d=-6[/tex]).
Replacing the values:
[tex]a_n=72+(n-1)(-6)[/tex]
[tex]a_n=72-6n+6[/tex]
[tex]a_n=72-6n+6[/tex]
[tex]a_n=78-6n[/tex]
Where [tex]n[/tex] is the row
Since we want to now the number of bricks in the 14th row, [tex]n=14[/tex]:
[tex]a_{14}=78-6(14)[/tex]
[tex]a_{14}=78-84[/tex]
[tex]a_{14}=-6[/tex]
Since bricks can't be negative, we can conclude that this is an impossible real-life situation.

Liz earns a salary of $2,100 per month, plus a commission of 4% of her sales. She wants to earn at least $2,900 this month. Enter an inequality to find amounts of sales that will meet her goal. Identify what your variable represents. Enter the commission rate as a decimal.
Let S = the amount of sales.
She earns 4% of her sales, this would be written as 0.4S ( you multiply the percent as a decimal by the amount of sales).
You then need to add that amount to her salary so you now have 0.4s + 2100
She wants to earn at least 2900 so the inequality becomes:
2900 ≥ 0.4s + 2100
Her sales would need to be:
800 ≥0.4s
s≥ 800/0.4
s ≥ 2000
At a breakfast buffet, 54% of people choose coffee for their beverage while 16% choose juice. Also, 12% choose both coffee and juice. What percentage of people chose coffee only?
Answer:
The answer is 42%.
Step-by-step explanation:
If we make a Venn diagram, we get 12% in the middle, meaning that 12% of people chose both coffee and juice.
54% is the total amount of people who chose coffee, including the % of people who chose coffee as well as juice.
So, we need to subtract 12% from 54%, therefore giving us 42%.
The percentage of people choose coffee only is 42%.
We have given that,

A survey was conducted at a local elementary school. Students were asked to identify their favorite color. The percentages of students who chose each color are shown.
Please fill out:
It is/is not likely that you will choose a person whose favorite color is red.
It is most likely that you will choose a person whose favorite color is _____.
The probability that you choose a student who picked red as his or her favorite color is ___%, but the probability that you chose a person who picked another color is ___%.
Answer:
It is not likely that you will choose a person whose favorite color is red.
It is most likely that you will choose a person whose favorite color is something other than red.
Step-by-step explanation:
The probability that you choose a student who picked red as his or her favorite color is 45%, but the probability that you choose a person who picked another color is 55%.
It is not likely that you will choose a person whose favorite color is red. It is most likely that you will choose a person whose favorite color is blue. The probability that you choose a student who picked red as his or her favorite color is 10%, but the probability that you chose a person who picked another color is 90%.
To solve this problem, we need to analyze the given percentages of students who chose each color as their favorite. The percentages provided are as follows:
- Red: 10%
- Blue: 40%
- Green: 20%
- Yellow: 15%
- Purple: 10%
- Orange: 5%
The total probability of all possible outcomes must equal 100%. In this case, the sum of the percentages of all colors equals 100%, confirming that the probabilities are correctly distributed among the color choices.
Now, let's address the first part of the question: It is/is not likely that you will choose a person whose favorite color is red. Since red has the lowest percentage (10%), it is the least likely choice among all the colors. Therefore, it is not likely that you will choose a person whose favorite color is red.
Next, we determine which color is most likely to be chosen. Since blue has the highest percentage (40%), it is the most likely choice. Thus, it is most likely that you will choose a person whose favorite color is blue.
To calculate the probability of choosing a student who picked red as their favorite color, we use the given percentage for red, which is 10%. This is the probability of randomly selecting a student who prefers red.
Finally, to find the probability of choosing a person who picked any color other than red, we subtract the probability of choosing red from the total probability (100%). This gives us 100% - 10% = 90%. Therefore, the probability that you chose a person who picked another color is 90%.
In conclusion, the probability of choosing a student who likes red is 10%, and the probability of choosing a student who likes any other color is 90%. The most likely color to be chosen is blue.

An office tower is shown in the attached diagram. It consists of a rectangular prism with a square base and a square based right pyramid.
a. Calculate the height of the tower from the ground to the top of the roof's apex.
b. Determine the volume of air inside the building, including the inside of the pyramid-shaped top.
Answer:
[tex]\boxed{\text{a. 111.1 m; b. 56 575 m}^{3}}[/tex]
Step-by-step explanation:
a. Height
(i) Height of prism
The height of the prism is 70 m.
(ii) Height of pyramid
Consider the red triangle in the diagram.
The diagonal of the square base is given by
d² = a² + a² = 2a²
d² = 2(26)² = 2 ×676 = 1352 m²
d = √1352 = 36.77 m
The base of the triangle R is
R = ½d = ½ × 36.77 = 18.38 m
Now,
h² + R² = e²
h² + 18.38² = 45²
h² + 338 = 2025
h² = 1687
h = 41.07 m
(iii) Total height
Total height = height of prism + height of pyramid = 70 + 41.07 = 111.1 m
b. Volume
(i) Volume of prism
V = lwh
V = 70 × 26 × 26 = 47 320 m³
(ii) Volume of pyramid
The formula for the volume of a square pyramid is
V = ⅓a²h
V = ⅓ × 26² × 41.07 = 9255 m³
(iii) Total volume
Total volume = volume of prism + volume of pyramid
V = 47320 + 9255 = 56 575 m³
The total height of the building is [tex]\boxed{\textbf{111.1 m}}[/tex]
The total volume of the building is [tex]\boxed{\textbf{56 575 m}^{3}}[/tex]

Step-by-step explanation:
The equation
x² + y² = r²
Represents a circle centred at the origin with radius r
x² + y² = 25 ← is in this form and
is a circle centre (0, 0) with r = 5
ANSWER
circle
EXPLANATION
The given equation is
[tex] {x}^{2} + {y}^{2} = 25[/tex]
To determine the type of conic, we analyze the coefficient and sign of the quadratic terms.
If the coefficient of the quadratic terms are equal and have the same sign,then the conic is a circle.
If the coefficient of the quadratic terms are equal and have opposite signs,then the conic is a hyperbola.
If the coefficient of the quadratic terms are not equal and have the same sign,then the conic is an ellipse.
Since the coefficients are all 1 and the signs are positive, the given conic is a circle.

Second period: 3, 2, 3, 1, 3, 4, 2, 4, 3, 1, 0, 2, 3, 1, 2
Third period: 4, 5, 3, 4, 2, 3, 4, 1, 8, 2, 3, 1, 0, 2, 1, 3
What is the best measure of spread for the first period and why?
median because there is and outlier
Final answer:
The best measure of spread for the first period is the range, which is found by subtracting the smallest value from the largest value in the dataset.
Explanation:
The best measure of spread for the first period is the range.
The range is found by subtracting the smallest value from the largest value in a dataset. For the first period, the smallest value is 0 and the largest value is 9, so the range is 9 - 0 = 9.
The range is a good measure of spread because it gives the distance between the minimum and maximum values, providing an idea of how much the data values vary.
a car and a lorry started travelling at the same time from town r to town s.

Answer:
112.5 km
Step-by-step explanation:
The lorry needed 45 minutes to travel the remaining 0.4 of the journey and was traveling at 60 km/hr.
First, convert minutes to hours:
45 min × (1 hr / 60 min) = 0.75 hr
Now use distance equation:
distance = rate × time
0.4d = 60 × 0.75
d = 112.5
The distance between the towns is 112.5 km.

Suki has 54 rock songs, 92 dance songs and 12 classical songs on her playlist. If Suki’s music player randomly selects a song from the playlist, what is the probability that the song will not be a classical song?
Answer:
92.4% or 73/79
Step-by-step explanation:
You have to add up all the individual songs, which is 158. Then add up the number of songs that aren't classical, which is 146. Then divide 146 by 158 which gives you your answer.
To find the probability that a randomly selected song from Suki's playlist is not a classical song, follow these steps:
1. **Find the total number of songs**: Add up the number of rock songs, dance songs, and classical songs to get the total number of songs in Suki's playlist.
Total number of songs = Number of rock songs + Number of dance songs + Number of classical songs
Total number of songs = 54 rock songs + 92 dance songs + 12 classical songs
Total number of songs = 158 songs
2. **Calculate the probability of selecting a classical song**: To calculate the probability of selecting a classical song, divide the number of classical songs by the total number of songs.
Probability of selecting a classical song = Number of classical songs / Total number of songs
Probability of selecting a classical song = 12 / 158
3. **Calculate the probability of not selecting a classical song**: The probability of not selecting a classical song is the complement of the probability of selecting a classical song. To get this probability, subtract the probability of selecting a classical song from 1.
Probability of not selecting a classical song = 1 - Probability of selecting a classical song
Probability of not selecting a classical song = 1 - (12 / 158)
4. **Compute the final probability**: Perform the subtraction from step 3 to get the final probability.
Probability of not selecting a classical song = 1 - (12 / 158)
Probability of not selecting a classical song ≈ 0.92405 (rounded to five decimal places)
Therefore, when Suki's music player randomly selects a song, the probability that the song will not be a classical song is approximately 0.92405, or 92.405%.

When Ella does 13 push-ups and 7 sit-ups, it takes a total of 60 seconds. In comparison, she needs 96 seconds to do 13 push-ups and 19 sit-ups. How long does it take Ella to do each kind of exercise?
It takes Ella ___ seconds to do a push-up and ___ seconds to do a sit-up.
The answer is:
It takes Ella 3 seconds to do a push-up and 3 seconds to do a sit up.
Why?To find how many seconds Ella took to do a push-up and a sit-up we must write two equations using the given information.
Let be "x" the time needed to push-ups and "y" be the time needed to do sit-ups.
So, writing the equations we have:
First equation,
If she can do 13 push-ups and 7 sit-ups in 60 seconds, we have:
[tex]13x+7y=60[/tex]
Second equation,
If she can do 13 push-ups and 19 sit-ups in 96 seconds, we have:
[tex]13x+19y=96[/tex]
Now, creating a system of equations, and using the reduction method to solve it, we have:
[tex]\left \{ {{13x+7y=60} \atop {13x+19y=96}} \right.[/tex]
Multiplying the first equation by -1, we have:
[tex]\left \{ {{-13x-7y=-60} \atop {13x+19y=96}} \right.[/tex]
[tex]\left \{ {{-13x-7y=-60} \atop {13x+19y=96}} \right\\\\12y=36\\\\y=\frac{36}{12}=3[/tex]
Then, substituting "y" into the first equation, we have:
[tex]13x+7y=60[/tex]
[tex]13x+7(3)=60[/tex]
[tex]13x+21=60[/tex]
[tex]13x=60-21=39[/tex]
[tex]x=\frac{39}{13}=3[/tex]
Hence, we have that It takes Ella 3 seconds to do a push-up and 3 seconds to do a sit up.
Have a nice day!
Solve the equation below for x.
| 2(x+5)= 3(x-4)
Answer:
x=22
Step-by-step explanation:
2(x+5)=3(x-4)
2x+10=3x-12
-x=-22
x=22
Step 1: Distribute the numbers outside the parentheses to each number inside the parentheses
(2 * x) + (2 * 5) = (3 * x) + (-4 * 3)
2x + 10 = 3x - 12
Step 2: Combine like terms
2x goes with 3x. To do this subtract 2x to both sides (subtraction is the opposite of addition)
(2x - 2x) + 10 = (3x - 2x) - 12
0 + 10 = x - 12
10 = x - 12
10 goes with -12. To do this add 12 to both sides (addition is the opposite of subtraction)
10 + 12 = x + (-12 + 12)
22 = x + 0
22 = x

In 5 hours, the car will travel 800 kilometers.
To convert the car's speed from miles per hour to kilometers per hour, you multiply by the conversion factor of 1.6 kilometers per 1 mile. Therefore, a speed of 100 miles per hour is equivalent to 100 × 1.6 = 160 kilometers per hour.
Next, to calculate how many kilometers the car will travel in 5 hours at the speed of 160 kilometers per hour, you simply multiply the speed by the time. The car will travel 160 km/h × 5 h = 800 kilometers in 5 hours.

How many solutions does the equation -6y+13+9y=8y-3
Answer:
Single Solution of 3.2 (16/5)
Step-by-step explanation:
3x = 8x -16 <--- I combine like terms.
-5x = -16
-16/-5 = x
x = 3.2
BTW Negative times a Negative equals a positive.
To find the solutions to the equation -6y + 13 + 9y = 8y - 3, combine like terms, isolate the variable, and solve for y. The equation has one solution, which is y = 3.2.
Explanation:To find the solutions to the equation -6y + 13 + 9y = 8y - 3, we need to simplify the equation and solve for y. First, combine like terms by adding the y terms on the left side and the constant terms on the right side. This gives us 3y + 13 = 8y - 3. Next, subtract 3y from both sides to isolate the variable term on the right side. This gives us 13 = 5y - 3. Then, add 3 to both sides to isolate the variable term. This gives us 16 = 5y. Finally, divide both sides by 5 to solve for y. This gives us y = 16/5 or y = 3.2.
