Suppose that a function y=f(x) is increasing on the interval [6,7]. a)The graph of y = f(x + 8) is increasing over the interval [−2, −1].
Explanation:
To determine the interval over which the graph of y = f(x + 8) is increasing, we need to consider the effect of the transformation x + 8 on the original interval [6, 7].
When we substitute x + 8 into the function, it shifts the graph horizontally to the left by 8 units. So, we need to find the new interval that corresponds to the original interval [6, 7] after the shift.
Let's start with the left endpoint of the original interval. When we substitute x = 6 into x + 8, we get 6 + 8 = 14. Therefore, the left endpoint of the new interval is 14.
Next, we consider the right endpoint of the original interval. Substituting x = 7 into x + 8, we get 7 + 8 = 15. Hence, the right endpoint of the new interval is 15.
Therefore, the graph of y = f(x + 8) is increasing over the interval [14, 15]. However, since we shifted the graph to the left by 8 units, the interval becomes [14 - 8, 15 - 8], which simplifies to the final answer of [-2, -1]. Thus, the graph of y = f(x + 8) is increasing over the interval [-2, -1].

Given the equation below,
\(y=-16t^2+64t\)To find the maximum point, dy/dt = 0.
Differentiating the equation above,
\(\begin{gathered} y=-16t^2+64t \\ \frac{dy}{dt}=-32t+64 \end{gathered}\)Where dy/dt = 0,
\(\begin{gathered} -32t+64=0 \\ -32t=-64 \\ t=\frac{-64}{-32}=2 \end{gathered}\)Substituting for t into the equation, maximum height is'
\(\begin{gathered} y=-16t^2+64t \\ \text{Where t = 2} \\ y=-16(2)^2+64(2) \\ y=-16(4)+128_{} \\ y=-64+128=64 \end{gathered}\)Hence, the maximum height of the football is 64 ft.
The vertex form is to be used which is given below as,
\(y=-16(t-2)^2+64\)Where (h, k) represents the coordinate of the vertex and k is the maximum height.
2. Find all of the values of x where the following function is not continuous. For each value, state whether the discontinuity is removable or not. x2 + 2x + 1 f(x) x2 + 3x + 2 =
The function f(x) = x^2 + 2x + 1 / (x^2 + 3x + 2) is not continuous at x = -1 and x = -2. The discontinuity at x = -1 is removable because the function can be redefined at that point to make it continuous.
The discontinuity at x = -2 is non-removable because there is a vertical asymptote at that point, which cannot be removed by redefining the function. At x = -1, both the numerator and denominator of the function become zero, resulting in an indeterminate form.
By factoring both expressions, we find that f(x) can be simplified to f(x) = (x + 1) / (x + 1) = 1, which defines a single point that can replace the discontinuity. However, at x = -2, the denominator becomes zero while the numerator remains nonzero, resulting in an infinite value and a vertical asymptote. Therefore, the discontinuity at x = -2 is non-removable..

the average number of daily emergency room admissions at a hospital is 85 with a standard deviation of 37. in a simple random sample of 30 days, what is the probability that the mean number of daily emergency admissions is between 75 and 95? group of answer choices .8612 .1388 .8990 .2128 .9970
The probability that the mean number of daily emergency admissions is between 75 and 95 is approximately 0.8990.
To find the probability that the mean number of daily emergency admissions is between 75 and 95, we can use the Z-score formula for sample means: Z = (X - μ) / (σ / √n), where X is the sample mean, μ is the population mean, σ is the standard deviation, and n is the sample size.
First, calculate the Z-scores for both 75 and 95:
Z_75 = (75 - 85) / (37 / √30) ≈ -1.62
Z_95 = (95 - 85) / (37 / √30) ≈ 1.62
Now, use a Z-table to find the probabilities corresponding to these Z-scores. P(Z ≤ 1.62) ≈ 0.9474 and P(Z ≤ -1.62) ≈ 0.0526.
Finally, subtract the probabilities to find the probability between the two Z-scores:
P(-1.62 ≤ Z ≤ 1.62) = P(Z ≤ 1.62) - P(Z ≤ -1.62) ≈ 0.9474 - 0.0526 ≈ 0.8948
Among the given answer choices, the closest value is 0.8990.
Therefore, the probability that the mean number of daily emergency admissions is between 75 and 95 is approximately 0.8990.

scores on an english test are normally distributed with a mean of 33.3 and a standard deviation of 7.1. find thescore that separates the top 41% from the bottom 59%
The score that separates the top 41% from the bottom 59% is approximately 35.08. To find the score that separates the top 41% from the bottom 59% of scores on an English test with a mean of 33.3 and a standard deviation of 7.1, we need to use the standard normal distribution.
First, we need to find the z-score that corresponds to the top 41% of scores, which can be found using a standard normal distribution table or a calculator. The z-score corresponding to the top 41% is approximately 0.27. We can then use the formula z = (x - μ) / σ to find the corresponding raw score, x, where μ is the mean and σ is the standard deviation. Rearranging the formula gives us x = zσ + μ, which gives us the score that separates the top 41% from the bottom 59%.
In this case, we have z = 0.27, σ = 7.1, and μ = 33.3. Plugging these values into the formula gives us x = 0.27 * 7.1 + 33.3, which simplifies to x = 35.08. Therefore, the score that separates the top 41% from the bottom 59% is approximately 35.08.
This means that if a student scores above 35.08 on the English test, they would be in the top 41% of scores, while if they score below 35.08, they would be in the bottom 59% of scores.

what is the length and width of a basketball court
The length of a standard basketball court is 94 feet (28.65 meters), and the width is 50 feet (15.24 meters).
A standard basketball court is rectangular in shape and follows certain dimensions specified by the International Basketball Federation (FIBA) and the National Basketball Association (NBA). The length and width of a basketball court may vary slightly depending on the governing body and the level of play, but the most commonly used dimensions are as follows:
The length of a basketball court is typically 94 feet (28.65 meters) in professional settings. This length is measured from baseline to baseline, parallel to the sidelines.
The width of a basketball court is usually 50 feet (15.24 meters). This width is measured from sideline to sideline, perpendicular to the baselines.
These dimensions provide a standardized playing area for basketball games, ensuring consistency across different courts and facilitating fair play. It's important to note that while these measurements represent the standard dimensions, there can be slight variations in court size depending on factors such as the venue, league, or specific regulations in different countries.

A camera shop stocks eight different types of batteries, one of which is type A76. Assume there are at least 31 batteries of each type. (a) How many ways can a total inventory of 31 batteries be distributed among the eight different types
Answer: 12,620,256
Step-by-step explanation:
Given: The camera shop socks eight different types of batteries and there re at least 31 batteries of each type.
Here we want to select r= 31 batteries from n= 8 kinds of batteries, then formula we use to find number of ways is \(^{n+r-1}C_r=\ ^{31+8-1}C_{31}\)
\(=^{38}C_{31}=\dfrac{38!}{31!(38-31)!}\\\\=\dfrac{38!}{31!7!}\\\\=\dfrac{38\times37\times36\times35\times34\times33\times32\times31!}{31!\times5040}\\\\=12620256\)
Hence, the number of ways can a total inventory of 31 batteries be distributed among the eight different types = 12,620,256
The union of two sets is a set that contains only the elements that appear in both sets
a. True
b. False
The union of two sets is to avoid counting the same elements twice.
What is set?
The mathematical logic subfield of set theory investigates sets, which can be loosely defined as collections of objects. Although any object can be combined into a set, set theory, as a mathematical discipline, focuses primarily on those that are relevant to mathematics as a whole.
Given union of set
(A ∪ B),
The set of all objects that are members of either A or B, or both, is the union of the sets A ∪ B.
let us take example,
A = { 1, 2, 3, 4}
B = {3, 4, 5, 6, 7}
(A ∪ B) = { 1, 2, 3, 4} ∪ {3, 4, 5, 6, 7}
we can simply write all of A and B's elements in a single set to avoid duplicates to find A U B.
(A ∪ B) = {1, 2, 3, 4, 5, 6, 7}
Hence the union of two sets is a set that contains all the elements of both set and avoid duplicates.
