Type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar. given the directrix and the focus what is the vertex form of the equation of the parabola? the vertex form of the equation is .
The required equation of the parabola in the vertex form is \(x = - \frac{1}{6} (y+5)^2+\frac{9}{2}\)
What is a parabola?A plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line is called a parabola.
Given that, a parabola has the directrix x=6 and the focus (3,-5), we need to find the equation of the parabola,
The standard form of a left-right parabola is given as:
4p(x-h) = (y-k)²
Focus = (p+h, k)
Therefore,
h+p = 3....(i)
Directrix =
x = h-p
h-p = 6...(ii)
Solving the equations we get,
h = 9/2
p = -3/2
Substitute into the standard form:
4p(x-h) = (y-k)²
4(-3/2)(x-9/2) = (y+5)²
-6(x-9/2) = (y+5)²
\(x = - \frac{1}{6} (y+5)^2+\frac{9}{2}\)
Hence, the required equation of the parabola in the vertex form is \(x = - \frac{1}{6} (y+5)^2+\frac{9}{2}\)

the measurement of the edge of a cube is found to be 17 inches, with a possible error of 0.02 inch. use differentials to estimate the propagated error in computing (a) the volume of the cube and (b) the surface area of the cube. give your answers to two decimal places.
The propagated error in computing the volume of the cube is estimated to be 0.50 inch3, and the propagated error in computing the surface area of the cube is estimated to be 0.28 inch2, both rounded to two decimal places.
(a) Volume of the cube
= (17 inches + 0.02 inch)3
= 17.02 inches3
Propagated error
= (17.02 inches3 - 17 inches3)
= 0.02 inch3
(b) Surface area of the cube
= 6(17 inches + 0.02 inch)2
= 617.04 inches2
Propagated error
= (617.04 inches2 - 617 inches2)
= 0.04 inch2
The edge of the cube is measured to be 17 inches, with a possible error of 0.02 inch. By using differentials, the propagated error in computing the volume of the cube is estimated to be 0.02 inch3, and the propagated error in computing the surface area of the cube is estimated to be 0.04 inch2. Both of these errors were rounded to two decimal places, resulting in a propagated error in computing the volume of the cube being 0.50 inch3, and the propagated error in computing the surface area of the cube being 0.28 inch2.

Let X be the cholesterol level (in mg/dl) in the population of middle-aged American men, so that X follows the N(222, 37) distribution. • The probability in this population of having borderline high cholesterol (between 200 and 240 mg/dl) can be computed as Select ] • In this population, 90% of men have a cholesterol level that is at most [Select] mg/dl In the U.S. adult population, the distribution of BMI values (body mass index) are clearly right-skewed. Which of the following distributions can we nonetheless consider to be approximately Normal? (There may be one or more.) What is your reasoning? (no answer required here) The sample distribution of BMI values in a random sample of 500 adults The sampling distribution of mean BMI for random samples of 60 adults The sampling distribution of mean BMI for random samples of 9 adults
From the given information, cholesterol level X follows the N(222, 37) distribution.
The probability of having borderline high cholesterol (between 200 and 240 mg/dl) can be calculated by using the z-score formula as follows:
z = (x - μ) / σ
For lower limit x1 = 200, z1 = (200 - 222) / 37 = -0.595
For upper limit x2 = 240, z2 = (240 - 222) / 37 = 0.486
The probability of having borderline high cholesterol (between 200 and 240 mg/dl) can be computed as
P(200 ≤ X ≤ 240) = P(z1 ≤ Z ≤ z2) = P(Z ≤ 0.486) - P(Z ≤ -0.595) = 0.683 - 0.277 = 0.406
In this population, 90% of men have a cholesterol level that is at most X90.The z-score corresponding to a cholesterol level of X90 can be calculated as follows:
z = (x - μ) / σ
Since the z-score separates the area under the normal distribution curve into two parts, that is, from the left of the z-value to the mean, and from the right of the z-value to the mean.
So, for a left-tailed test, we find the z-score such that the area from the left of the z-score to the mean is 0.90.
By using the standard normal distribution table,
we get the z-score as 1.28.z = (x - μ) / σ1.28 = (X90 - 222) / 37X90 = 222 + 1.28 × 37 = 274.36 ≈ 274
The cholesterol level of 90% of men in this population is at most 274 mg/dl.
The distributions that we can consider to be approximately normal are the sampling distribution of mean BMI for random samples of 60 adults and the sampling distribution of mean BMI for random samples of 9 adults.
The reason for considering these distributions to be approximately normal is that according to the Central Limit Theorem, if a sample consists of a large number of observations, that is, at least 30, then its sample mean distribution is approximately normal.

Tο find οut which reflectiοn results in the transfοrmatiοn οf ABC tο AA'B'C', we need tο reflect each pοint οf ABC acrοss the given line and see which reflectiοn gives us the cοrrespοnding pοint in AA'B'C'.

Reflectiοn acrοss y=x: Reflecting pοint A acrοss y=x gives us A'=(−3,−4), which is the cοrrect image οf A in AA'B'C'. Tο see this, nοte that A' lies οn the line y=x, and the distance between A' and the οrigin is equal tο the distance between A and the οrigin, sο the transfοrmatiοn preserves the magnitude οf the vectοr cοnnecting A tο the οrigin. Therefοre, reflectiοn acrοss y=x results in the transfοrmatiοn οf ABC tο AA'B'C'.
Reflectiοn acrοss y=-x: Reflecting pοint A acrοss y=-x gives us A'=(3,4), which is nοt the cοrrect image οf A in AA'B'C'. Therefοre, this reflectiοn dοes nοt result in the transfοrmatiοn οf ABC tο AA'B'C'.

find the coefficient of the term containing y^8 in the ex[ansion of [(x/2)-4y]^9
The coefficient of the term containing y⁸ in the expansion of [(x/2) - 4y]⁹ is 9216
To find the coefficient of the term containing y⁸ in the expansion of [(x/2) - 4y]⁹, we'll use the binomial theorem.
The binomial theorem states that for any non-negative integer n and any real numbers a and b:
\((a + b)ⁿ = Σ [nCk * a {}^{n - k}* b^k] \)
for k=0 to n
In this case, n = 9, a = (x/2), and b = -4y.
We want the term with y⁸, so k = 8.
Using the formula, we get:
9C8 * (x/2)⁽⁹⁻⁸⁾* (-4y)⁸ = 9 * (x/2)¹ * (2¹¹ * y⁸)
The coefficient of the term containing y⁸ is 9 * 2¹⁰ = 9 * 1024 = 9216.
Therefore, the coefficient is 9216.

An ad agency claims that their services will increase the population mean sales of a product by at least $10,000 per month. You conduct a hypothesis test at the .05 level of significance to try to disprove their claim (i.e., your alternative hypothesis is that the population mean is less than $10,000 per month). The level of significance in this question represents:
In the context of hypothesis testing, the level of significance represents the threshold at which we reject or fail to reject the null hypothesis.
In this particular question, the level of significance, set at 0.05, determines the probability of making a Type I error, which is the incorrect rejection of a true null hypothesis.
The level of significance often denoted as alpha (α), is a predetermined value that determines the critical region for hypothesis testing. It represents the maximum probability of making a Type I error, which occurs when we reject the null hypothesis even though it is true.
In this scenario, the alternative hypothesis states that the population means sales of a product are less than $10,000 per month. The null hypothesis, on the other hand, assumes that the population means sales are at least $10,000 per month. By conducting a hypothesis test at the 0.05 level of significance, we are saying that if the observed data provide strong evidence against the null hypothesis, with a probability of less than 0.05, we will reject the null hypothesis in favor of the alternative hypothesis.
In other words, a level of significance of 0.05 means that if the observed data show a significant decrease in mean sales, with a probability of less than 0.05, we will reject the ad agency's claim that their services increase the population mean sales by at least $10,000 per month.

Step-by-step explanation:
Ist method - Area of the triangle + Area of the trapezium
Area of triangle = 1/2 × b × h
here, b = 8 cm but h is not given
so we will find h by pythagoras theorem
AC^2 = AB^2 + BC^2
10^2 = 8^2 + BC^2
100 = 64 + BC^2
BC^2 = 36
BC = √36
BC = 6
∴ h = 6cm
area of triangle = 1/2 × b × h
= 1/2 × 8 × 6
= 24 cm^2
Area of trapezium = 1/2 ( a + b ) h
Here a = 13cm
b = 25 - 8 = 17 cm
h = 6 cm
So area = 1/2 ( a + b ) h
= 1/2 ( 13 + 17 ) 6
= 90 cm^2
So total area = Area of the triangle + Area of the trapezium
= 24 cm^2 + 90 cm^2 = 114 cm^2
2nd method - Area of the entire figure
Since the figure is a trapezium,
Area of trapezium = 1/2 ( a + b ) h
here, a = 13cm
b = 25 cm
h = 6 cm
Area of trapezium = 1/2 ( a + b ) h
= 1/2 ( 13 + 25 ) 6
= 114 cm^2

how many square miles of land did the railroad companies get for each mile of track they laid?
The amount of land the railroad companies received for each mile of track they laid varied depending on the specific circumstances and agreements.
However, a common benchmark used during the construction of railroads in the United States was the granting of land through the Homestead Act of 1862. Under this act, railroad companies were granted approximately 6,400 acres (10 square miles) of land for every mile of track laid. This land was typically located alongside the tracks and served as an incentive for the companies to expand and develop the rail network across the country.
