The end behavior of the given function is As x → –∞, f(x) → –∞, and as x → ∞, f(x) → –∞.
What is end behavior of function?The term "end behavior" describes the behaviour or trend of a function's graph as its x-values go closer to positive or negative infinity. It explains how the function "ends" or acts when x is extremely large (positive infinity) or extremely small (negative infinity). The degree and leading coefficient of the polynomial formulation of the function can be used to predict the final behaviour. For instance, the left and right ends of the graph will both point upward for a function with an odd-degree polynomial and a positive leading coefficient (towards positive infinity).
For the function f(x) = -2∛x as x approaches negative infinity because the function has a negative coefficient in front of the cube root, which means that as x decreases significantly, the absolute value of the cube root increases. The function also approaches negative infinity as x approaches very big (positive) values and the cube root approaches very small absolute values. As a result, the function's final behaviour is that it approaches negative infinity as x gets closer to both negative and positive infinity.

Answer:
The function f(x) = -2∛x represents a cube root function that is multiplied by -2.
As x approaches negative infinity, the cube root of x becomes more negative, and when it is multiplied by -2, it becomes more positive. Therefore, as x → –∞, f(x) → ∞.
As x approaches positive infinity, the cube root of x becomes more positive, and when it is multiplied by -2, it becomes more negative. Therefore, as x → ∞, f(x) → –∞.
Therefore, the correct answer is: As x → –∞, f(x) → ∞, and as x → ∞, f(x) → –∞. D.

The end behavior is if x becomes very large the value of f(x) also becomes very large, The function will approach zero more slowly as x approaches negative infinity, because 7 is greater than 1.
To describe the end behavior of f(x), we need to consider the limit of f(x) as x approaches positive infinity and negative infinity. We can write this as:
lim f(x) as x → ±∞ = ±∞
This means that as x becomes very large (either positive or negative), the value of f(x) also becomes very large (either positive or negative).
b. If we change the base of the exponential function from 5/7 to 7, the graph of f(x) will change in the following ways:
The function will grow faster, because 7 is greater than 5/7.
The function will start at a higher value, because f(0) = 4(7)^0 = 4.
The function will approach zero more slowly as x approaches negative infinity, because 7 is greater than 1.
c. If we add a constant to the exponential function, the graph of f(x) will be shifted vertically by the amount of the constant. In this case, the graph of f(x) will be shifted downwards by 2 units, because we are subtracting 2 from the function.

As we have shown that both AE is congruent to CE and BE is congruent to DE.
Now, let's focus on the diagonals of the parallelogram, AC and BD. We are told that they intersect at point E.
To prove that AE is congruent to CE, we can use the fact that opposite sides of a parallelogram are congruent. Since AC is a diagonal of the parallelogram, it divides it into two congruent triangles, AEC and CED. This is because AE is parallel to CD (as they are opposite sides of the parallelogram), and EC is common to both triangles.
Therefore, by the Side-Angle-Side (SAS) congruence theorem, we can conclude that triangle AEC is congruent to triangle CED. In particular, this means that AE is congruent to CE.
Similarly, to prove that BE is congruent to DE, we can use the same reasoning. Since BD is a diagonal of the parallelogram, it divides it into two congruent triangles, AEB and DEC. This is because BE is parallel to AC (as they are opposite sides of the parallelogram), and ED is common to both triangles.
Therefore, by the SAS congruence theorem, we can conclude that triangle AEB is congruent to triangle DEC. In particular, this means that BE is congruent to DE.

In a town of 42800 people.48% are male.the rest are female. how many more female are there than males
Answer:
First, we need to find out how many people are male and female in the town:
Step-by-step explanation:
Male population = 48% of 42800 = 20544
Female population = 100% - 48% = 52% of 42800 = 22256
To find out how many more females there are than males, we need to subtract the male population from the female population:
Female population - Male population = 22256 - 20544 = 1712
Therefore, there are 1712 more females than males in the town.

What is the solution set of 6x-24 =0? x^2
The solution to the Quadratic equation x², when x satisfies the equation 6x - 24 = 0, is x²= 16.
What is Quadratic equation?A quadratic equation is a polynomial equation of the second degree, meaning it contains one or more terms that involve a variable raised to the power of two. The standard form of a quadratic equation is:
ax^2 + bx + c = 0,where a, b, and c are constants, and x is the variable.
According to given informationThe given equation is 6x - 24 = 0.
To solve for x, we can isolate x on one side by adding 24 to both sides of the equation:
6x - 24 + 24 = 0 + 24
6x = 24
Then, we can solve for x by dividing both sides by 6:
6x/6 = 24/6
x = 4
Therefore, the solution to the equation 6x - 24 = 0 is x = 4.
Now, to solve for x², we can simply substitute x = 4 into the equation x²:
x² = 4²
x^2 = 16
Therefore, the solution to the equation x², when x satisfies the equation 6x - 24 = 0, is x² = 16.

For a 20-year endowment insurance on (65) with face amount 1,000:
benefits are payable at the moment of death, or at the end of 20 years if the
insured survives.
− Mortality follows the Illustrative Life Table with = 0.06.
− Deaths are uniformly distributed between integral ages.
− Gross premiums are payable at the beginning of each year for 20 years, and are
determined by the equivalence principle.
− Commissions and taxes are 35% of the gross premium in the first year, 5% in the
other years, and are paid at the beginning of each year.
− Other expenses are 1 in all years, paid at the beginning of the year.
Calculate the gross premium for the endowment insurance
The gross premium for the endowment insurance is 73.
How to solveTo calculate the gross premium for the endowment insurance, we can use the equivalence principle, which states that the present value of the premiums must equal the present value of the benefits.
We can break down the problem into two parts: the present value of the death benefit and the present value of the endowment benefit.
First, let's calculate the present value of the death benefit. The death benefit is payable at the moment of death, and the probability of dying at age x is given by qx, where qx is the probability of surviving to age x.
Since deaths are uniformly distributed between integral ages, we can assume that deaths occur at the midpoint of the age interval. Therefore, the probability of dying at age x can be approximated by
.
Let's denote the present value of the death benefit as DB. Using the equivalence principle, we can write:
DB = A*(1+0.35) - E0 - C1 - 0.05A(1+0.05)
- 0.05A(1+0.05)
- ... - 0.05A(1+0.05)
where A is the annual premium, E0 is the expense paid at the beginning of the first year, and C1 is the commission and tax paid at the beginning of the first year.
The factor (1+0.35) accounts for the commission and tax on the first year premium.
Using the formula for the present value of a perpetuity, we can simplify the above equation to:
DB =
= 116.22
where q65/2 is the probability of dying at age 65. We can obtain q65/2 from the Illustrative Life Table, which gives
q65/2 = 0.112488.
Therefore, the gross premium for the endowment insurance is 73.

Cari owns a horse farm and a horse trailer that can transport up to 8,000 pounds of livestock and tack. She travels with 5 horses whose combined weight is 6,240 pounds. Let t represent the average weight of tack per horse. What inequalities could show the weight of each horse?
The inequalities that could show the weight of each horse are:
h ≤ 1248
t ≤ 352
To determine the inequalities that could show the weight of each horse, we can use the fact that the total weight of the horses and tack must be less than or equal to the capacity of the horse trailer. We can set up the following inequalities:
5h + 5t ≤ 8000
where h represents the average weight of each horse.
However, we don't know the value of t, so we need to express it in terms of h. We are given that the combined weight of the horses is 6,240 pounds, so we can write:
5h ≤ 6240
Solving for h, we get:
h ≤ 1248
This means that the weight of each horse must be less than or equal to 1,248 pounds.
Now we can substitute this upper bound for h into the first inequality to get:
5(1248) + 5t ≤ 8000
6240 + 5t ≤ 8000
5t ≤ 1760
t ≤ 352
This means that the average weight of tack per horse must be less than or equal to 352 pounds.

Tom and Philip were given the graph of a linear function and asked to find the slope. Tom says that the slope is 12 while Philip says that the slope is 2.
Which reason correctly justifies Tom's answer?
Without seeing the graph of the linear function, it is impossible to determine if Tom's answer of 12 is correct or incorrect. However, it is important to understand the concept of slope and how it is calculated for a linear function.
The slope of a linear function represents the rate at which the y-coordinate changes for each unit increase in the x-coordinate. In other words, it measures the steepness of the line. Mathematically, the slope of a line is defined as the ratio of the change in the y-coordinate to the change in the x-coordinate between any two points on the line.
To calculate the slope of a line given its graph, one can choose any two points on the line and find the difference in their y-coordinates and x-coordinates. The slope is then the ratio of the change in y-coordinates to the change in x-coordinates. This can be expressed as:
slope = (change in y-coordinate) / (change in x-coordinate)
Now, if Tom has correctly identified two points on the line and calculated the difference in their y-coordinates and x-coordinates, and if he has obtained a ratio of 12 for the change in y-coordinate to the change in x-coordinate, then his answer of 12 for the slope would be correct.
However, it is also possible that Tom made an error in his calculation, or that he misread the graph, and obtained an incorrect answer. Therefore, it would be necessary to verify his calculations by checking the points he used and the formula he applied.
In conclusion, without further information about the graph of the linear function and the points chosen by Tom to calculate the slope, it is impossible to determine if his answer of 12 is correct or incorrect.

The conclusion that about 8.6% of the students in the school have a January birthday is not necessarily valid based on the information provided.
The sample size of the survey is too small (only 3 students with January birthdays) and limited to one math class, so it may not be representative of the whole school population. Additionally, the sample is not randomly selected, which introduces the possibility of selection bias.

An inequality that represent this situation is x + 21 ≥ 47 and the solution is x ≥ 26.
The inequalities that can be used to represent the situation are;
D. x - 7.35 ≥ 2.87
E. x ≥ 10.22
How to write and determine the solution to the inequalities?Based on the information provided about the math test, the following inequality must be solved by students;
x - 5 < 11
By adding 5 to both sides of the inequality, we have the following:
x - 5 + 5 < 11 + 5
x < 16
Therefore, the error which Mason made was subtracting 5 from both sides.
Since the temperature dropped 6 degrees before it was fixed and it was still at least 67 degrees when the heater started working again, we can model it as follows;
x - 4 ≥ 67
x ≥ 71
Since Ramiro has $21 and wants buy a skateboard that cost $47, the amount of money that he needs can be modeled by this inequality;
x + 21 ≥ 47
x ≥ 47 - 21
x ≥ 26
In conclusion, the inequalities that can be used to represent the total amount, x, Kendra needs for the bead are;
x - 7.35 ≥ 2.87
x ≥ 2.87 + 7.35
x ≥ 10.22

A fifth grade teacher believes that 12% of her students are late for class. If the teacher is right, what is the probability that the proportion of late students in a sample of 538 students would differ from the population proportion by less than 3%? Round your answer to four decimal places.
Answer:
Step-by-step explanation:
Given:
Proportion of students who are late for class in the population: p = 0.12
Sample size: n = 538
Margin of error: E = 0.03
The standard error of the proportion can be calculated using the formula:
SE = sqrt(p*(1-p)/n)
SE = sqrt(0.12*0.88/538)
SE = 0.019
The margin of error corresponds to a z-score at the 97.5th percentile (since we want the probability of the sample proportion being within 3% of the population proportion in either direction, which gives us a two-tailed test with an alpha level of 0.025 on each side). This z-score can be found using a standard normal distribution table or calculator and is approximately 1.96.
The margin of error can also be calculated using the formula:
E = z*(SE)
0.03 = 1.96*(0.019)
To find the probability that the sample proportion differs from the population proportion by less than 3%, we need to find the area under the standard normal distribution curve between the z-scores of -1.96 and 1.96. This area is equivalent to the probability of the sample proportion being within 3% of the population proportion. This probability can be found using a standard normal distribution table or calculator and is approximately 0.8534.
Therefore, the probability that the proportion of late students in a sample of 538 students would differ from the population proportion by less than 3% is 0.8534 or 85.34% (rounded to four decimal places)
find the surface area to the nearest whole number. do not round until the end. X=4 units Y= 13 units Z= 7 units (giving brainliest!!!)
The Surface area of figure is 396.896 unit².
We have,
x = 4 unit, y = 13 unit and z = 7 unit.
First Surface Area of Cylinder
= 2πrh
= 2(3.14)(4)(7)
= 175.84 unit²
and, Surface Area of Cone
= πrl
= (3.14)(4)(13.6)
= 170.816 unit²
Thus, the Surface area of figure is
= 175.84 + 170.816 + 50.24
= 396.896 unit²

What is equation?An equation is a mathematical statement that shows the equality between two expressions. It typically consists of mathematical symbols, such as numbers, variables, operators, and equal signs. Equations are used to represent relationships between quantities and are commonly used in various fields of mathematics, science, and engineering to solve problems, make predictions, and describe phenomena.
Define fraction?A fraction is a mathematical representation of a part or parts of a whole. It consists of two numbers, separated by a horizontal or diagonal line, called the numerator and the denominator. The numerator represents the number of parts being considered, while the denominator represents the total number of equal parts that make up the whole.
