What are the 3 rules of limits?.
We can calculate limits considering the following rules:
Constant Rule The constant rule of limit calculus is utilized when a function is given in which there is no identical variable available. This rule states that the limit of the constant function remains as it is.
Limu→a k = k
Constant time function rule This rule is utilized when there are stagnant coefficients along with the identical variables of the function. This rule states that the constant coefficient will be written outside the limit notation.
Limu→a kf(u) = k Limu→a f(u)
Sum Rule The sum rule is utilized when there are two or more terms or functions given along with the additional sign among them. This rule states that the denotation of the limit will apply to every function separately.
Limu→a [f(u) + g(u)] = Limu→a [f(u)] + Limu→a [g(u)]
Difference Rule The difference rule is utilized when two or more terms or functions are mentioned along with the minus sign among them. This rule expresses that the notation of the limit will be implied to each function segregation.
Limu→a [f(u) – g(u)] = Limu→a [f(u)] – Limu→a [g(u)]

Josie combines 6.72 ounces of strawberries with 6.47 ounces of blueberries to make fruit bowls. She pours the fruit equally into 3 bowls, and has 2.57 ounces of fruit left over. How many ounces of fruit are in each bowl?
Josie combines 6.72 ounces of strawberries with 6.47 ounces of blueberries and divides them equally into 3 bowls. There are 2.57 ounces of fruit left over. We need to find the number of ounces of fruit in each bowl.
To find the number of ounces of fruit in each bowl, we need to divide the total amount of fruit by the number of bowls. The total amount of fruit is the sum of the strawberries and blueberries, which is 6.72 + 6.47 = 13.19 ounces.
If we divide 13.19 ounces by 3, we get 4.3967 ounces per bowl. However, we need to consider the fact that there are 2.57 ounces of fruit left over. This means that the 13.19 ounces of fruit cannot be divided equally into 3 bowls.
To distribute the remaining 2.57 ounces of fruit equally among the 3 bowls, we can add 2.57/3 = 0.8567 ounces to each bowl. Adding this amount to the initial division, we get approximately 4.3967 + 0.8567 = 5.2534 ounces per bowl.
Therefore, each bowl contains approximately 5.2534 ounces of fruit.

End behavior
please explanation required! :3
Step-by-step explanation:
it is simple for such a line.
x goes to -infinity, and therefore y (or f(x)) also goes to -infinity.
x goes to +infinity, and therefore y (or f(x)) also goes to +infinity.
the difference between x and y values is just a constant factor (the slope). that constant factor becomes irrelevant, when the values approach infinity anyway. only the sign is relevant.
but in our case the slope is +1/+2 (the y value increases by +1 for every increase of x by +2).
so, the line (as we can see in the graph) is
y = 1/2 × x - 1
when x goes to +infinity, "-1" is irrelevant, and
1/2 × +infinity = +infinity.
when x goes to -infinity, again, "-1" is irrelevant, and
1/2 × -infinity = -infinity
If a negative relation exists between two variables, then low scores on one variable will be associated with _____ scores on the other variable.
If a negative relation exists between two variables, low scores on one variable will be associated with high scores on the other variable.
In a negative relationship between two variables, a decrease in one variable is accompanied by an increase in the other variable. This means that as scores on one variable decrease (i.e., low scores), the scores on the other variable tend to increase (i.e., high scores). The negative relationship implies an inverse pattern where the variables move in opposite directions.
The exact nature and strength of the negative relationship can vary, but the general trend is that low scores on one variable correspond to high scores on the other variable. This negative association provides insights into the behavior and interactions between the variables being examined.

The summer and winter solstices are the longest day and night of the year, respectively. The summer solstice happens between June 20 and June 21, while the winter solstice is between December 21 and December 23. At a latitude of 28° the summer solstice is 14.5 hours long and the winter solstice is 14 hours long. Write a sinusoidal equation modeling the hours of daylight in a year. Use t for the variable and measure t in weeks. For the purposes of this problem, idealize a year to be 52 weeks long, with the winter solstice a week before the new year. h(t) = __________
The correct answer is h(t) = 14.25 + 0.25 * sin((π/26) * t)
To model the hours of daylight in a year using a sinusoidal equation, we can consider the average length of daylight, the amplitude of the variation, and the period of the function.
Given:
Summer solstice (longest day) is 14.5 hours
Winter solstice (longest night) is 14 hours
Let's analyze the information:
Average daylight: The average daylight throughout the year would be the average of the summer and winter solstices. It can be calculated as:
Average daylight = (14.5 + 14) / 2 = 14.25 hours
Amplitude: The difference between the average daylight and the longest day or night is the amplitude. In this case, the amplitude is half the difference between the summer and winter solstices. It can be calculated as:
Amplitude = (14.5 - 14) / 2 = 0.25 hours
Period: We are modeling the function over a year, which we'll consider as 52 weeks. Since we want to measure time in weeks (t), the period of the function is 52 weeks.
Putting all the information together, we can write the sinusoidal equation:
h(t) = Average daylight + Amplitude * sin((2π / Period) * t)
Substituting the values we calculated:
h(t) = 14.25 + 0.25 * sin((2π / 52) * t)
Simplifying further, the sinusoidal equation modeling the hours of daylight in a year is:
h(t) = 14.25 + 0.25 * sin(π/26 * t)

Zamir needs to determine the height of the building
What’s the Height “A”
What’s Height “B”
What’s the Height of “X”
PLEASE
Answer:
Height of the building = 115.4 ft.
Step-by-step explanation:
Height of building = AB + 46.4 + CD + 30.5
By applying Pythagoras theorem in ΔABP,
(26)² = (10)²+ (AB)²
676 - 100 = AB²
AB² = 576
AB = 24 ft
By applying sine rule in ΔCDE,
cos(60°) = \(\frac{CD}{CE}\)
CD = CE × \(\frac{1}{2}\)
CD = \(\frac{29}{2}\)
CD = 14.5 ft
Total Height = 24 + 46.4 + 14.5 + 30.5

if $x$ and $y$ are positive integers such that $5x+3y=100$, what is the greatest possible value of $xy$?
The greatest possible value of $xy$ is $17\times5=\boxed{85}$. To get the greatest possible value of $xy$, we need to maximize the values of $x$ and $y$. We can start by rearranging the equation $5x+3y=100$ to solve for one of the variables in terms of the other:
$5x+3y=100 \implies 5x=100-3y \implies x=\frac{100-3y}{5}$
Since $x$ must be a positive integer, $100-3y$ must be divisible by 5. The largest multiple of 3 less than 100 is 99, so we can try values of $y$ starting from 1 and working up to 33 (because if $y\geq34$, then $5x\leq0$, which is not positive).
When $y=1$, we get $x=\frac{100-3}{5} = 19.4$, which is not an integer.
When $y=2$, we get $x=\frac{100-6}{5} = 18.8$, which is also not an integer.
When $y=3$, we get $x=\frac{100-9}{5} = 18.2$, still not an integer.
When $y=4$, we get $x=\frac{100-12}{5} = 17.6$, still not an integer.
When $y=5$, we get $x=\frac{100-15}{5} = 17$, which is an integer.
From here, we can continue to increase $y$ and see that the values of $x$ will only decrease. Thus, the greatest possible value of $x$ is 17 and the corresponding value of $y$ is 5.

Find the area enclosed by y = 3x and y=x^2. Round your answer to one decimal place.
The area enclosed by the curves y = 3x and \(y = x^2\) is 13.5 square units (rounded to one decimal place).
To find the area enclosed by the curves y = 3x and \(y = x^2\), we need to find the points of intersection and integrate the difference between the curves with respect to x.
First, we find the points of intersection by setting the two equations equal to each other:
\(3x = x^2x^2 - 3x = 0x(x-3) = 0x = 0 or x = 3\)
So the curves intersect at the points (0,0) and (3,9).
To find the area enclosed between the curves, we integrate the difference between the curves with respect to x from x=0 to x=3:
Area =\(\int\limits (y = x^{2} \ to\ y = 3x) dx\) from 0 to 3
= \(\int\limits(3x - x^2) dx \ from \ 0 \ to \ 3\)
= \([3/2 x^2 - 1/3 x^3] from 0 to 3\)
= (27/2 - 27/3) - (0 - 0)
= 13.5 square units
Therefore, the area enclosed by the curves y = 3x and \(y = x^2\) is 13.5 square units (rounded to one decimal place).

Suppose two equally strong tennis players play against each other until one player wins three games in a row. The results of each game are independent, and each player will win with probability 1 2 . What is the expected value of the number of games they will play?
The expected value of the number of games the two equally strong tennis players will play until one wins three games in a row is 14.
Let's consider the possible sequences of games that can occur until one player wins three games in a row. We will denote the winning player as W and the losing player as L. The sequences can be represented as a combination of W's and L's, such as WWL, WLW, LWW, etc.
The key insight is that for each sequence, the last game played must be won by the player who wins three games in a row. This means that the number of games played until the streak ends is fixed at three. However, the preceding games can have various combinations of wins and losses.
To calculate the expected value, we need to consider all possible sequences and their probabilities. Since each player has a 50% chance of winning each game, the probability of any specific sequence occurring is (1/2)^n, where n is the length of the sequence.
We can calculate the expected value by summing the product of the number of games played in each sequence and its corresponding probability.
Considering all possible sequences and their probabilities, the expected value of the number of games played until one player wins three games in a row is found to be 14.

Three students have started a fence-painting business. Working together, Pragnesh and Qazi can paint the fence in 2 hours. Similarly, Pragnesh and Ronghui can paint the fence in 3 hours when they work together. Finally, when Qazi and Ronghui work together, they can paint the fence in 4 hours. How long would it take if all three students worked together to paint the fence.
Answer:
in about 0.92 hours or 55.2 minutes
Step-by-step explanation:
The time they take to paint the room:
Pragnesh and Qazi = 2 hours
Pragnesh and Ronghui = 3 hours
Qazi and Ronghui = 4 hours
Meaning, each hour (1) they'll paint:
Pragnesh and Qazi = \(\frac{1}{2th}\) of the room
Pragnesh and Ronghui = \(\frac{1}{3th}\) of the room
Qazi and Ronghui = \(\frac{1}{4th}\) of the room
By summing all their work abilities we can determine how long it would take if all three students worked together to paint the fence, which is:
\(\frac{1}{2} + \frac{1}{3} + \frac{1}{4} = \frac{13}{12th}\) of the room each hour. Therefore the whole (1) room would be painted in 1 ÷ \(\frac{13}{12}\) = \(\frac{12}{13} hours\) or 0.92 hours or 55.2 minutes (0.92 * 60).
