what is the equation for a circle that has a center at (-8,-5) and a point on the circle at (-1,1)
Answers
The equation of a circle with a center at (-8, -5) and a point on the circle at (-1, 1) can be found using the distance formula. The equation is (x + 8)^2 + (y + 5)^2 = 98.
To find the equation of a circle, we need to know the coordinates of the center and a point on the circle. Let's denote the center of the circle as (h, k) and the point on the circle as (x1, y1).
The distance formula can be used to find the radius of the circle, which is the distance between the center and any point on the circle. The formula is:
r = sqrt((x1 - h)^2 + (y1 - k)^2)
In this case, the center is (-8, -5) (h = -8, k = -5), and the point on the circle is (-1, 1) (x1 = -1, y1 = 1).
Substituting these values into the distance formula, we get:
r = sqrt((-1 - (-8))^2 + (1 - (-5))^2)
= sqrt((7)^2 + (6)^2)
= sqrt(49 + 36)
= sqrt(85)
Now that we know the radius is sqrt(85), we can write the equation of the circle using the formula:
(x - h)^2 + (y - k)^2 = r^2
Plugging in the values, we have:
(x + 8)^2 + (y + 5)^2 = (sqrt(85))^2
(x + 8)^2 + (y + 5)^2 = 85
Therefore, the equation of the circle with a center at (-8, -5) and a point on the circle at (-1, 1) is (x + 8)^2 + (y + 5)^2 = 85.

8 1 practice the pythagorean theorem and its converse form k
Answers
The Pythagorean theorem is a fundamental concept in geometry that relates the lengths of the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Mathematically, it can be expressed as:
a² + b² = c²
where a and b are the lengths of the two legs of the right triangle, and c is the length of the hypotenuse.
The converse of the Pythagorean theorem states that if the square of the length of one side of a triangle is equal to the sum of the squares of the lengths of the other two sides, then the triangle is a right triangle.
The Pythagorean theorem is a powerful tool in solving problems involving right triangles. It allows us to calculate unknown side lengths or determine whether a triangle is a right triangle based on the lengths of its sides. It has numerous applications in various fields, including engineering, architecture, physics, and navigation.
Understanding the Pythagorean theorem and its converse is essential for working with right triangles and applying geometric principles. It provides a foundation for further exploration of trigonometry and advanced geometric concepts.

Answers
Answer:
Q=17
Step-by-step explanation:
5q − 10 = 75
Add ten to both sides=5q=85
Divide both sides by 5=q=17
Answer:
A. 17
Step-by-step explanation:
Solve for q:
\( \longrightarrow\) 5q - 10 = 75
Add 10 to both sides:
\( \longrightarrow\) 5q + (10 - 10) = 10 + 75
10 - 10 = 0:
\( \longrightarrow\) 5q = 75 + 10
75 + 10 = 85:
\( \longrightarrow\) 5q = 85
Divide both sides of 5q = 85 by 5:
\( \longrightarrow\) \( \sf \dfrac{5q}{5} = \dfrac{85}{5} \)
\( \sf \dfrac{5}{5} \) = 1:
\( \longrightarrow\) q = \( \sf \dfrac{85}{5} \)
\( \sf \dfrac{85}{5} \) = 17:
\( \longrightarrow\) q = 17

Answers
z1 = (lb - lb) / lb = z1, z2 = (lb - lb) / lb = z2. If the percentage is high, it means many women are within the limits and few are excluded. If the percentage is low, it means many women are excluded.
To find the percentage of women whose weights are within the specified limits, we need to calculate the z-scores for the lower and upper limits and then find the area under the normal distribution curve between those z-scores.
First, we calculate the z-score for the lower limit: z1 = (lower limit - mean) / standard deviation.
z1 = (lb - lb) / lb = z1
Next, we calculate the z-score for the upper limit: z2 = (upper limit - mean) / standard deviation.
z2 = (lb - lb) / lb = z2
Using the z-table or a calculator, we can find the area between z1 and z2. This area represents the percentage of women whose weights are within the specified limits.
Now, to determine if many women are excluded from those specifications, we need to look at the percentage calculated in the previous step. If the percentage is high, it means many women are within the limits and few are excluded. If the percentage is low, it means many women are excluded.

Sharkey's Fun Center contains a number of electronic games as well as a miniature golf course and various rides located outside the building. Paul Sharkey, the owner, would like to construct a water slide on one portion of his property. Mr. Sharkey gathered the following information about the slide: a. Water slide equipment could be purchased and installed at a cost of $525,000. According to the manufacturer, the slide would be usable for 12 years after which it would have no salvage value. b. Mr. Sharkey would use straight-line depreciation on the slide equipment. c. To make room for the water slide, several rides would be dismantled and sold. These rides are fully depreciated, but they could be sold for $127.750 to an amusement park in a nearby city. d. Mr. Sharkey concluded that about 50,000 more people would use the water slide each year than have been using the rides. The admission price would be $5.00 per person (the same price the Fun Center has been charging for the old rides). e. Based on experience at other water slides, Mr. Sharkey estimates that annual incremental operating expenses for the slide would be: salaries, $95,000; insurance, $5,800; utilities, $14,600; and maintenance, $11,400. Required: 1. Prepare an income statement showing the expected net operating income each year from the water slide. 2-a. Compute the simple rate of return expected from the water slide. 2-b. Based on the above computation, would the water slide be constructed if Mr. Sharkey requires a simple rate of return of at least 13% on all investments? 3-a. Compute the payback period for the water slide. 3-b. If Mr. Sharkey accepts any project with a payback period of five years or less, would the water slide be constructed?
Answers
1. The expected net operating income each year from the water slide is $238,150.
2. The simple rate of return expected from the water slide is 12.5%.
Let us discuss in a detailed way:
⇒ To calculate the net operating income, we need to consider the additional revenue from increased attendance and subtract the incremental operating expenses.
The additional attendance from the water slide is estimated to be 50,000 people per year. With an admission price of $5.00 per person, the additional revenue would be $250,000 ($5.00 x 50,000).
The incremental operating expenses for the water slide amount to $126,800 ($95,000 + $5,800 + $14,600 + $11,400).
Therefore, the expected net operating income each year is $238,150 ($250,000 - $126,800).
⇒ The simple rate of return is calculated by dividing the average annual net income by the initial investment cost and expressing it as a percentage.
The average annual net income is calculated by subtracting the annual operating expenses from the additional revenue generated. In this case, the average annual net income is $113,350 ($238,150 - $124,800).
The initial investment cost is $525,000.
Using these values, the simple rate of return is 21.6% ($113,350 / $525,000).

m∠D = 55°, DE ≈ 8.40 units, DF ≈ 14.65 units
Answers
Answer:
D
Step-by-step explanation:
the sum of the 3 angles in Δ DEF = 180° , that is
∠ D + 90° + 35° = 180°
∠ D + 125° = 180° ( subtract 125° from both sides )
∠ D = 55°
------------------------
using the tangent and cosine ratios in the right triangle
tan35° = \(\frac{opposite}{adjacent}\) = \(\frac{DE}{EF}\) = \(\frac{DE}{12}\) ( multiply both sides by 12 )
12 × tan35° = DE , then
DE ≈ 8.40 ( to 2 dec. places )
--------------------------
cos35° = \(\frac{adjacent}{hypotenuse}\) = \(\frac{EF}{DF}\) = \(\frac{12}{DF}\) ( multiply both sides by DF )
DF × cos35° = 12 ( divide both sides by cos35° )

Answers
The series ∑(n=1 to ∞) 1/5^n converges.
To determine the convergence or divergence of the series ∑(n=1 to ∞) 1/5^n, we can use the geometric series test.
The general form of a geometric series is ∑(n=0 to ∞) ar^n, where a is the first term and r is the common ratio.
In this case, a = 1 and r = 1/5.
For a geometric series to converge, the absolute value of r must be less than 1 (|r| < 1). If |r| ≥ 1, the series will diverge.
In our series, |1/5| = 1/5 < 1, so the series is a geometric series that converges.

The probability of a random patient being alcoholic with elevated cholesterol levels is 55/80, or 0.6875. The probability of a random patient being nonalcoholic is 320/400, or 0.8. Lastly, the probability of a random patient being nonalcoholic with Non elevated cholesterol levels is 248/400, or 0.62.
To calculate the probability of a random patient being alcoholic with elevated cholesterol levels, we must first determine the total number of patients with elevated cholesterol levels. This can be done by adding the number of alcoholic patients (55) with elevated cholesterol levels to the number of nonalcoholic patients (72) with elevated cholesterol levels.
The result is a total of 127 patients with elevated cholesterol levels. This means that out of 400 patients, 55 of them were alcoholic and had elevated cholesterol levels. Therefore, the probability of a random patient being alcoholic with elevated cholesterol levels is 55/400, or 0.6875.
The probability of a random patient being nonalcoholic is equal to the total number of nonalcoholic patients (320) divided by the total number of patients (400). This yields a probability of 0.8.

Over the past seven years, Kathy's uncle has been paying her a monthly allowance of $1,000 in arrears, which means the allowance is deposited into her bank account at the end of each month. The interest rate on the allowance is 6% per annum, compounded monthly. Since the allowance is paid at the end of each month, we can calculate the future value of the monthly allowance using the formula for compound interest: Future Value = P * (1 + r/n)^(n*t).
Where: P = Principal amount (monthly allowance) = $1,000; r = Annual interest rate = 6% = 0.06; n = Number of compounding periods per year = 12 (monthly compounding); t = Number of years = 7. Plugging in the values: Future Value = 1000 * (1 + 0.06/12)^(12*7) ≈ $1,117.17.

The level of measurement for the temperature of refrigerators cannot be determined based on the given information. The temperature could potentially be measured on a nominal scale if the refrigerators were categorized into different temperature ranges. However, without further context, it is not possible to determine the specific level of measurement.
The horsepower of race car engines can be measured on a ratio scale. Ratio scales have a meaningful zero point and allow for meaningful comparisons of values, such as determining that one engine has twice the horsepower of another.
The marital status of school board members can be measured on a nominal scale. Nominal scales are used for categorical data without any inherent order or ranking. Marital status categories, such as "married," "single," "divorced," etc., can be assigned to school board members.
The ratings of television programs, such as "poor," "fair," "good," and "excellent," can be measured on an ordinal scale. Ordinal scales represent data with ordered categories or ranks, but the differences between categories may not be equal or measurable.
The ages of children enrolled in a daycare can be measured on an interval scale. Interval scales have equal intervals between values, allowing for meaningful differences and comparisons. Age, measured in years or months, can be represented on an interval scale.
