What x values are not included in the domain of the quotient of two functions? You can choose more than 1 answer.
1. Any x -values that are in the domains of both functions.
2. Any x-values that are not in the domain of both functions.
3. Any x-values that result in the numerator being equal to 0.
4. Any x-values that result in the denominator being equal to 0.
The correct answer is 4. Any x-values that result in the denominator being equal to 0.
When finding the domain of the quotient of two functions, we need to consider the domains of both the numerator and the denominator. The domain of a function is the set of all possible input values for which the function is defined. For the quotient of two functions, this means that the domain is the set of all x-values that are in the domains of both the numerator and denominator.
However, there is one additional restriction on the domain of the quotient of two functions. The denominator of the quotient cannot be equal to 0, because division by 0 is undefined. Therefore, any x-values that result in the denominator being equal to 0 are not included in the domain of the quotient.
In summary, the x-values that are not included in the domain of the quotient of two functions are any x-values that result in the denominator being equal to 0.

A total of 699 tickets were sold for the school play. They were either adult tickets or student tickets. There were 51 fewer student tickets sold than adult tickets. How many adult tickets were sold?
Answer:
Sold:
adults: 375 tickets
student: 324 tickets
Step-by-step explanation:
a + s = 699 Eq. 1
a = s + 51 Eq. 2
a = adult tickets sold
s = student tickets sold
Replacing Eq. 2 im Eq. 1
(s+51) + s = 699
2s + 51 = 699
2s = 699 - 51
2s = 648
s = 648/2
s = 324
From Eq. 2
a = 324 + 51
a = 375
Check:
From Eq. 1:
a + s = 699
375 + 324 = 699

Given that n is an integer greater than 1, explain why the largest prime factor of
2(7^n) - 2(7^n-1)+7^n+1 is 61.
Answer:
See below.
Step-by-step explanation:
Given expression:
[tex]2(7^n) - 2(7^{n-1})+7^{n+1}[/tex]
[tex]\textsf{Apply exponent rule} \quad a^b \cdot a^c=a^{b+c}[/tex]
[tex]\implies 2(7^n) - 2(7^{n-1})+7^{n} \cdot 7^1[/tex]
[tex]\textsf{Apply exponent rule} \quad \dfrac{a^b}{a^c}=a^{b-c}[/tex]
[tex]\implies 2(7^n) - 2\left(\dfrac{7^{n}}{7^{1}}\right)+7^{n}\cdot 7^1[/tex]
Simplify:
[tex]\implies 2(7^n) - \dfrac{2}{7} (7^n)+7(7^{n})[/tex]
Factor out the common term 7ⁿ:
[tex]\implies \left(2- \dfrac{2}{7} +7\right)7^{n}[/tex]
Therefore:
[tex]\dfrac{61}{7}(7^n)[/tex]
A prime number is a whole number greater than 1 that cannot be made by multiplying other whole numbers. Therefore, the factors of a prime number are 1 and the number itself.
If n is an integer greater than 1, the number will always have at least 4 factors (1, 7, 61 and itself) and therefore cannot be a prime number by definition.
For example:
[tex]n = 2 \implies \dfrac{61}{7}(7^2)=61 \times 7=427[/tex]
[tex]n = 3\implies \dfrac{61}{7}(7^3)=61 \times 7^2=2989[/tex]
Therefore, the largest prime number is when n = 1:
[tex]n = 1 \implies \dfrac{61}{7}(7^1)=61[/tex]
One angle of a triangle meaure 10 degree greater than the mallet angle and the third angle meaure 10° le than twice the mallet angle find the meaure of the three angle
One angle in a triangle is 10 degrees larger than the smallest angle, while the third angle is 10 degrees less than twice the smallest angle. As a result, the three angles are 55°, 45°, and 80°.
Three vertices and three sides make up a triangle. The angles of the triangle are formed by the connection of the three sides end to end at a single point. The sum of the triangle's three angles is 180 degrees.
Let's consider the three angles of the triangle as ∠P, ∠Q, and ∠R. Let's consider Q as the smallest angle. The sum of angles P, Q, and R is given as ∠P+∠Q+∠R=180°
Then, ∠P = ∠Q + 10° and ∠R = 2∠Q - 10°. Substituting these two angle values in the above equation,
[tex]\begin{aligned}\angle Q + 10^{\circ}+\angle Q+2\angle Q - 10^{\circ}&=180^{\circ}\\4\angle Q&=180^{\circ}\\\angle Q&=45^{\circ}\end{aligned}[/tex]
Then,
∠P = ∠Q + 10° = 45°+ 10° = 55°
∠R = 2∠Q - 10° = 2(45°) - 10° = 90° - 10° = 80°
The answers are 55°, 45°, and 80°.

An agricultural land of 2 hectares is planted with cereals. 20% of it is planted with corn, 10% with oats, and the rest with wheat. Find how many dynyms is each surface
First, we need to find the total area of the land that is planted with cereals. To do this, we multiply the total area of the land, which is 2 hectares, by the percentage of the land that is planted with cereals, which is 100% - 20% - 10% = 70%. This gives us a total area of 2 hectares * 70% = 1.4 hectares.
Next, we need to divide the total area of 1.4 hectares into three parts, one for each type of cereal. Since 20% of the land is planted with corn, the area of land planted with corn is 1.4 hectares * 20% = 0.28 hectares. Similarly, since 10% of the land is planted with oats, the area of land planted with oats is 1.4 hectares * 10% = 0.14 hectares. Finally, the area of land planted with wheat is 1.4 hectares - 0.28 hectares - 0.14 hectares = 0.98 hectares.
Since 1 hectare is equal to 10,000 square meters, the area of land planted with corn is 0.28 hectares * 10,000 square meters/hectare = 2,800 square meters. The area of land planted with oats is 0.14 hectares * 10,000 square meters/hectare = 1,400 square meters, and the area of land planted with wheat is 0.98 hectares * 10,000 square meters/hectare = 9,800 square meters. So, each surface of land planted with corn is 2,800 square meters, each surface of land planted with oats is 1,400 square meters, and each surface of land planted with wheat is 9,800 square meters.
The length of a rectangle is 2m longer than its width. If the perimeter of the rectangle is , 60 find its length and width.
Answer:
Let the width of the rectangle be w.
Then the length of the rectangle is w+2.
The perimeter of the rectangle is the sum of all its sides, so it is 2(w) + 2(w+2) = 60.
Expanding the parentheses and combining like terms, we get:
2w + 2w + 4 = 60
4w + 4 = 60
4w = 56
w = 14
The width of the rectangle is 14.
The length of the rectangle is 14+2 = 16.
Therefore, the length of the rectangle is 16 and the width is 14.

In the second year, its value decreased by 30%
Work out whether the clock increased in value, decreased in value or remained the
same value over the two years.
You must show your working clearly.
The overall price considering the percentages is decreased.
What are percentages?Percentage is defined as "out of 100." Similar to fractions and decimals, percentages are used in mathematics to represent subsets of a whole. When expressing a sum as a percentage, 100 equal components are regarded to make up the whole. A percentage can be shown by the symbol % or, less frequently, by the abbreviation 'pct'.
In stores, online, in commercials, and in the media, you can see percentages practically anywhere. Understanding what percentages signify is a crucial skill that could help you save time and money and raise your employability.
Calculation:Let us suppose mary bought that antique clock for 100$.
So now in the first year its value is increased by 30% which is 100+30 = 130$ after the 1 st year.
Now the clock price is 130$
So now in the second year its value is decrease by 30% which is 130- 39 = 91 $
So the overall clock price has been decreased by $9 since mary bought it.
The overall price considering the percentages is decreased.

When a coin is weighted, there is a two-thirds chance that it will land on its head. suppose you toss this coin 15 times. let x represent the number of heads. Mean = 10 and Standard deviation = 2.88
The mean of x, which represents the number of heads when the coin is tossed 15 times, is 10. This is because the probability of getting heads is two-thirds, meaning that two out of every three tosses will result in heads.We apply the following formula to determine the standard deviation:
Standard Deviation = √(p*q*n), where p is the probability of getting heads, q is the probability of getting tails, and n is the number of tosses. In this case, p = 2/3, q = 1/3, and n = 15, so the standard deviation of x is 2.88.

1. A model car travels horizontally after being released. The car travels a distance d metres in a time of t seconds. d is directly proportional to t. The car travels 20 metres in a time of 2 seconds. a) Calculate the distance the car travels in 3 seconds.
If d is directly proportional to t, then we can say that d = k * t, where k is a constant of proportionality. We can find the value of k by substituting the given values for d and t into this equation:
d = k * t
20 = k * 2
Solving for k, we get k = 10.
Now that we know the value of k, we can calculate the distance the car travels in 3 seconds by substituting 3 for t in the equation d = k * t:
d = 10 * 3
d = 30
Therefore, the car travels 30 meters in a time of 3 seconds.
