The wheel of a covered wagon has a diameter of 2 feet what is the wheels circumference?

Answer:

What's the question????

Step-by-step explanation:

1. Find the graph of the parabola attached below

2. Vertex (-4, 2)   Focus (-7/2, 2)  Directrix (x = -9/2)  Endpoints (-7/2, 1) (-7/2, 3)

For the parabola,  x = 1/2(y-2)² - 4 we will use the equation x = 4p(y-k)² + h,

Vertex → (h, k)

In our given equation, (y - 2) → (y - k), so k = 2. The term on the rightmost side of our equation (-4) → h in the form, so we know h = -4. ∴  vertex (-4, 2).

focus → (h, k) = (-4, 2); P = 1/2

Parabola is symmetric around the x axis and so the focus lies a distance P, from the center, along the x axis.

∴  Focus is (-4 + p, 2)

(-4 + 1/2, 2) ⇒ (-7/2, 2)

directrix → x = d

Parabola is symmetric around the x axis and therefore the directrix is a line paralled to the y axis a distance away from the ceter (-4, 2) x coordinate.

∴ x = -4 - p   ⇒ x = -4 - 1/2

x = 9/2

focal chord endpoints →

The focus of the parabola is (-7/2, 2).

The y-coordinate of the focus is 2, so the y-coordinates of the endpoints of the focal chord are 2 + 1 and 2 - 1, → 3 and 1.

Therefore, the endpoints of the focal chord are:

(-7/2, 3) and (-7/2, 1).

Answer:

y = ⁷/5x + 13/10

Step-by-step explanation:

Recall: equation in slope-intercept form is given as y = mx + b

Thus, let's rewrite 14x - 10y = -13 in this form.

14x - 10y = -13

Add -14x to both sides

-10y = -14x - 13

Divide both sides by -10

-10y/-10 = -14x/-10 - 13/-10

y = ⁷/5x + 13/10

Answer:

The 95% confidence interval for the true difference between the mean home prices in the two areas is (-$29156.52, $1956.52).

Step-by-step explanation:

Before building the confidence interval, we need to understand the central limit theorem and subtraction of normal variables.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Subtraction between normal variables:

When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.

First area:

33 homes, mean of $168,300, standard deviation of $37,825. Thus:

\(\mu_1 = 168300\)

\(s_1 = \frac{37825}{\sqrt{33}} = 6584.5\)

Second area:

33 homes, mean of $181,900, standard deviation of $25,070. Thus:

\(\mu_2 = 1819000\)

\(s_2 = \frac{25070}{\sqrt{32}} = 4431.8\)

Distribution of the difference:

\(\mu = \mu_1 - \mu_2 = 168300 - 181900 = -13600\)

\(s = \sqrt{s_1^2+s_2^2} = \sqt{6584.5^2 + 4431.8^2} = 7937\)

Confidence interval:

\(\mu \pm zs\)

In which

z is the z-score that has a p-value of \(1 - \frac{\alpha}{2}\).

95% confidence level

So \(\alpha = 0.05\), z is the value of Z that has a p-value of \(1 - \frac{0.05}{2} = 0.975\), so \(Z = 1.96\).  

The lower bound of the interval is:

\(\mu - zs = -13600 - 1.96*7937 = -29156.52 \)

The upper bound of the interval is:

\(\mu + zs = -13600 + 1.96*7937 = 1956.52\)

The 95% confidence interval for the true difference between the mean home prices in the two areas is (-$29156.52, $1956.52).

Year 2: $773.50 * 0.91 = $704.69

Year 3: $704.69 * 0.91 = $641.95

...

Year 34: (continue the pattern)

We can continue this calculation for each year, but to save time, we can use an exponential decay formula:

Remaining Amount = Initial Amount * (1 - rate)^years

Substituting the values:

Remaining Amount = $850 * (1 - 0.09)^34

Calculating this expression:

Remaining Amount ≈ $850 * (0.91)^34 ≈ $255.88

After 34 years, approximately $255.88 will be left with Sally.

According to Classification of Quadrilaterals,

i. Both rectangles have 4 sides - True

ii. Both rectangles have 4 right angle - True

iii. Both rectangles have all sides the same length - False

The classification of Quadrilaterals

Quadrilaterals are a type of geometric shape that have four sides. There are different types of quadrilaterals, and they can be classified based on the characteristics of their sides and angles. The main classifications of quadrilaterals are:

Trapezoid or Trapezium: a quadrilateral with only one pair of parallel sides.

Kite: a quadrilateral whose two adjacent pairs of sides are of equal length.

Parallelogram: a quadrilateral with opposite sides that are parallel to each other.

Rhombus: a quadrilateral with all sides equal in length.

Rectangle: a quadrilateral with opposite sides that are parallel and all four angles are right angles (90 degrees).

Square: a quadrilateral with all sides equal in length and all four angles are right angles (90 degrees).

These are the main classifications of quadrilaterals, and each type has its own specific properties and characteristics that distinguish it from the others.

According to the given information:

i. Both have 4 sides - True

A rectangle has four sides because it is defined as a quadrilateral with two pairs of parallel sides and four right angles. This means that opposite sides of a rectangle are parallel to each other and have the same length, while adjacent sides are perpendicular to each other and form right angles.

So, by definition, a rectangle must have four sides in order to meet these criteria and be classified as a rectangle.

ii. Both have 4 right angle - True

In a rectangle, by definition, opposite sides are parallel to each other and adjacent sides are perpendicular to each other. This means that each of the four corners of a rectangle must form a right angle, where two sides meet at a 90-degree angle.

iii. Both have all sides the same length - False

Not all rectangles have all sides the same length. While a square is a type of rectangle where all sides are equal, rectangles can have different lengths for their adjacent sides.

Step-by-step explanation:

It seems you have a number x such that ...

 \(\dfrac{2}{5}(x-1)<\dfrac{3}{5}(x+1)\\\\2x-2<3x+3\qquad\text{multiply by 5, eliminate parentheses}\\\\-5<x\qquad\text{subtract $2x+3$}\)

This matches choice B: x > -5.

Answer:

  x = 31.2

Step-by-step explanation:

You want the solution to the proportion 12/x = 5/13.

You can eliminate the fractions by multiplying this equation by the least common denominator. That value is 13x, the product of these denominators. Multiplying by 13x, we have ...

  \(\dfrac{12}{x}\times13x=\dfrac{5}{13}\times13x\\\\\\12\cdot13=5\cdot x\qquad\text{simplified}\)

Now, the value of x is found by dividing both sides by its coefficient.

  \(\dfrac{12\cdot13}{5}=\dfrac{5x}{5}\\\\\\\dfrac{156}{5}=x\\\\\boxed{31.2=x}\)

__

Additional comment

The first step we did, multiplying by 13x, is also sometimes called "cross multiplication." The result of that step is that each numerator is multiplied by the opposite denominator.

Multiplying both sides of the equation by the same value (13x) is supported by the multiplication property of equality. The term "cross multiplication" is descriptive of the result, but is not a recognized property of equality. It is a good idea to keep the math operations you do grounded in the properties of equality.

You will notice that the steps we did were "multiply by 13x" and "divide by 5". These can be done at once by "multiply by 13x/5". Of course, that operation is done to both sides of the equation.

Any proportion can be written 4 ways:

  \(\dfrac{12}{x}=\dfrac{5}{13}\qquad\dfrac{x}{12}=\dfrac{13}{5}\qquad\dfrac{x}{13}=\dfrac{12}{5}\qquad\dfrac{13}{x}=\dfrac{5}{12}\)

These can be thought of as "upside down" and "sideways." We like the versions with the variable on top of a fraction, because the solution to that is simply multiplication by the variable's denominator.

Answer:55+52=107 and 55times5s equals 2860

Step-by-step explanation:

The simplified form of the expression 4x(x + 1) − (3x − 8)(x + 4) is -3x^2 - 4x - 32.

To simplify the expression 4x(x + 1) − (3x − 8)(x + 4), we can expand the parentheses and combine like terms.

Expanding the first term, we get 4x^2 + 4x.

Expanding the second term, we have -(3x)(x) - (3x)(4) - (-8)(x) - (-8)(4), which simplifies to -3x^2 - 12x - (-8x) - (-32), further simplifying to -3x^2 - 12x + 8x - 32.

Combining like terms, we obtain -3x^2 - 4x - 32.

We know 35 over 8 is \(\frac{35}{8}\)

And we know were trying to get 6

The unknown is the "add" which gives us X

Equation: x + \(\frac{35}{8}\) = 6

When we solve the equation we get x = 13/8

And leaves us with x = 6

1) The Point-Slope Formula (y – y1) = m(x – x1)

2) The Slope-Intercept Formula y = mx + b

To determine the equation of a line, you may use two variations of the general form of a line.

These formulas are:

1) The Point-Slope Formula (y – y1) = m(x – x1)

2) The Slope-Intercept Formula y = mx + b

The standard form of a linear equation, also known as the “general form“, is:

ax+by=c

The letters aa, bb, and cc are all coefficients. When using standard form, aa, bb, and cc are all replaced with real numbers. The letter x represents the independent variable and the letter y represents the dependent variable.

A few notes on Standard Form:

Let us now determine the y-intercept. Remember, this is where the line crosses the y-axis and where x=0 To do so, we will substitute 0 for x

3y-5x=30

3y-5(0)=30

Midpoint formula: The midpoint M of a line segment with endpoints (x1, y1) and (x2, y2) is given by:

M = ((x1+x2)/2, (y1+y2)/2)

Here, we know that the midpoint M is (4, -2), and one endpoint A is (2, 2). Let B be the other endpoint, so we can use the midpoint formula to find B:

4 = (2+x2)/2 --> 8 = 2+x2 --> x2 = 6

-2 = (2+y2)/2 --> -4 = 2+y2 --> y2 = -6
