The perimeter of a triangle is the total length of all its sides. To find the perimeter of a triangle, you need to add the lengths of its three sides.

If the triangle is a right triangle, with one angle measuring 90 degrees, you can use the Pythagorean theorem to find the length of the hypotenuse, which is the longest side of the triangle.

The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. Once you know the length of all three sides, you can simply add them together to find the perimeter.

For non-right triangles, you can use the distance formula or other geometric principles to find the length of each side. The distance formula is based on the Pythagorean theorem and states that the distance between two points in a plane is the square root of the sum of the squares of the differences between their coordinates.

Once you have the length of each side, you simply add them together to find the perimeter. For example, if a triangle has sides of length 5, 7, and 9 units, the perimeter would be:

Perimeter = 5 + 7 + 9 = 21 units.

The arithmetic average return is probably too high for longer periods and the geometric average is probably too low for shorter periods.

When we look at historical returns, the difference between the geometric and arithmetic average returns isn't too hard to understand.

To put it slightly differently, the geometric average tells you what you actually earned per year on average, compounded annually. The arithmetic average tells you what you earned in a typical year. You should use whichever one answers the question you want answered. A somewhat trickier question concerns forecasting the future, and there's a lot of confusion about this point among analysts and financial planners.

Now, If we have estimates of both the arithmetic and geometric average returns, then the arithmetic average is probably too high for longer periods and the geometric average is probably too low for shorter periods.

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

The fewest number of hours he would need to work to reach his goal of $280 is 28 hours working in the library.

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

Amount to earn = $280

Grocery store:

Earnings per hour = $8

1 hour = $8

Multiply 280/8 on both sides.

280/8 x 1 hour = $280

35 hours = $280

Library:

Earnings per hour = $10

1 hour = $10

Multiply 280/10 on both sides.

28 hours = $280

The perpendicular bisector of the line segment whose endpoint are (6,9) and (-2,5) is y = -2x + 11.

The line segment whose endpoint are (6,9) and (-2,5).

Let M be the midpoint of the endpoint.

So the coordinate of M = \(\left(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2}\right)\)

The coordinate of M = \(\left(\frac{6+(-2)}{2},\frac{9+5}{2}\right)\)

The coordinate of M = (2, 7)

The formula of slope m = \(\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\)

Slope of AB = m(1)

m(1) = (5 - 9)/(-2 - 6)

m(1) = -4/-8

m(1) = 1/2

The endpoints are perpendicular bisector. So in the perpendicular bisector slope is:

m(1)·m(2) = -1

m(2) = -1/m(1)

Now put the value of m(1)

m(2) = -1/(1/2)

m(2) = -2

Now the equation of the perpendicular bisector is;

y - \(y_{1}\) = m(x - \(x_{1}\))

As we know that; m = m(2) = -2; \(x_{1}\) = 2 and \(y_{1}\) = 7

Now put the values

y - 7 = -2(x - 2)

Use the distributive property

y - 7 = -2x + 4

Subtract 7 on both side, we get

y = -2x + 11

Answer:

Surface Area = 2 * (length * width + length * height + width * height)

Step-by-step explanation:

To find the surface area of a rectangular solid (also known as a rectangular prism), you need to calculate the areas of its six faces and then add them together. The formula for the surface area of a rectangular solid is:

Surface Area = 2 * (length * width + length * height + width * height)

Here are the steps to find the surface area:

Identify the length, width, and height of the rectangular solid.

Multiply the length by the width to find the area of the top and bottom faces.

Multiply the length by the height to find the area of the front and back faces.

Multiply the width by the height to find the area of the left and right faces.

Add up all the areas calculated in steps 2, 3, and 4.

Multiply the sum by 2 to account for the two identical sets of faces.

The result will be the surface area of the rectangular solid.

It's important to note that all measurements should be in the same unit (e.g., centimeters, inches) for accurate results.

Answer:

Step-by-step explanation:

The area of ​​the rectangular solid (parallelepiped) is calculated by adding the lateral area and twice the base area: Stot=Slat+2Sb; the area of ​​the rectangular parallelepiped is given by the sum of the areas of the six rectangles that make up its surface, ie Stot=2(ab+ah+bh).

To access the first element of an array of integers called "numbers," you can use the expression:
numbers[0]`
This expression uses the array name "numbers" and the index "0" to access the first element.

To access the last element of "numbers," assuming it contains 10 elements, use the expression:

`numbers[9]`

Here, we use the index "9" since arrays are zero-indexed, meaning the last element in a 10-element array has an index of 9.
To access the first element of the array called numbers, we would use the expression "numbers[0]."

To access the last element of the array, assuming it contains 10 elements, we would use the expression "numbers [9]" since arrays are zero-indexed in most programming languages.

To access the last element of the array regardless of its length, we can use the expression "numbers [numbers.length-1]," which subtracts 1 from the length of the array to access the last element.
To access the last element, regardless of its length, use the expression:

'numbers [numbers. length - 1]'

This expression uses the "length" property of the array to find the total number of elements and subtracts 1 to get the correct index for the last element.

Angle opposite the side of length 89 is 62.8° (approximately). Angle opposite the side of length 145 is 50.2° (approximately). Angle opposite the side of length 190 is 66.9° (approximately).

The question requires us to find out the value of each angle of a triangle given the lengths of its sides which are 145, 190, and 89 cm. Using the law of cosines given in Appendix E, we can use the following formula to find the angles of the triangle cos A = (b² + c² - a²) / 2bccos B = (a² + c² - b²) / 2accos C = (a² + b² - c²) / 2abWhere A, B, and C are the angles of the triangle, and a, b, and c are the sides opposite to the respective angles. We know the length of the sides of the triangle to be 145, 190, and 89 cm. We can label them as follows: a = 145 cm, b = 190 cm, and c = 89 cm. Now we can substitute these values into the above formula to calculate each angle as follows: Angle opposite side of length 89: cos A = (b² + c² - a²) / 2bc= (190² + 89² - 145²) / (2 * 190 * 89)= 0.4544A = cos-1(0.4544)A = 62.8° (approximately)Angle opposite side of length 145: cos B = (a² + c² - b²) / 2ac= (145² + 89² - 190²) / (2 * 145 * 89)= 0.6275B = cos-1(0.6275)B = 50.2° (approximately)Angle opposite side of length 190: cos C = (a² + b² - c²) / 2ab= (145² + 190² - 89²) / (2 * 145 * 190)= 0.4521C = cos-1(0.4521)C = 66.9° (approximately)

Therefore, the angle opposite the side of length 89 is approximately 62.8°, the angle opposite the side of length 145 is approximately 50.2°, and the angle opposite the side of length 190 is approximately 66.9°. Angle opposite the side of length 89 is 62.8° (approximately). Angle opposite the side of length 145 is 50.2° (approximately). Angle opposite the side of length 190 is 66.9° (approximately). Given sides of a triangle are 145, 190, and 89 cm. Using the law of cosines given in Appendix E, we can use the following formula to find the angles of the triangle. cos A = (b² + c² - a²) / 2bccos B = (a² + c² - b²) / 2accos C = (a² + b² - c²) / 2ab. We know the length of the sides of the triangle to be 145, 190, and 89 cm. We can label them as follows: a = 145 cm, b = 190 cm, and c = 89 cm. Now we can substitute these values into the above formula to calculate each angle as follows: Angle opposite side of length 89:cos A = (b² + c² - a²) / 2bc= (190² + 89² - 145²) / (2 * 190 * 89)= 0.4544A = cos-1(0.4544)A = 62.8° (approximately)

Angle opposite side of length 145:cos B = (a² + c² - b²) / 2ac= (145² + 89² - 190²) / (2 * 145 * 89)= 0.6275B = cos-1(0.6275)B = 50.2° (approximately)Angle opposite side of length 190:cos C = (a² + b² - c²) / 2ab= (145² + 190² - 89²) / (2 * 145 * 190)= 0.4521C = cos-1(0.4521)C = 66.9° (approximately)Therefore, the angle opposite the side of length 89 is approximately 62.8°, the angle opposite the side of length 145 is approximately 50.2°, and the angle opposite the side of length 190 is approximately 66.9°.Hence, we can conclude that the angles of the triangle are 62.8° (approximately), 50.2° (approximately), and 66.9° (approximately).

a. Decision rule: Reject the null hypothesis if the calculated z-value is less than or equal to -1.28. b. Calculated z-value: -1.8892. c. Conclusion: Reject the null hypothesis, indicating evidence that the population mean is less than 128.

To complete parts (a) through (c), we need to perform a hypothesis test for the given hypotheses

H0: μ = 128 (null hypothesis)

HA: μ ≤ 128 (alternative hypothesis)

Given: X= 119 (sample mean)

σ = 27 (population standard deviation)

n = 46 (sample size)

α = 0.10 (significance level)

a. The decision rule is to reject the null hypothesis if the calculated value of the test statistic is less than or equal to the critical value(s) of the test statistic. Since the alternative hypothesis is one-sided (μ ≤ 128), we will use a one-sample z-test and compare the calculated z-value with the critical z-value.

To find the critical z-value, we need to determine the z-value corresponding to the significance level α = 0.10. Looking up the critical value in the standard normal distribution table, we find that the critical z-value is -1.28 (rounded to two decimal places).

b. The calculated value of the test statistic, in this case, is the z-value. We can calculate the z-value using the formula

z = (X - μ) / (σ / √n)

Substituting the given values:

z = (119 - 128) / (27 / √46) ≈ -1.8892 (rounded to two decimal places)

c. The conclusion is based on comparing the calculated value of the test statistic with the critical value. Since the calculated z-value of -1.8892 is less than the critical z-value of -1.28, we have enough evidence to reject the null hypothesis. Therefore, we conclude that the population mean is less than 128.

The conclusion statement in part (c) is inconsistent with the given alternative hypothesis and should be revised accordingly.

In this problem we need to form the function of the population in a town.

Here it is given that the initial population of the town is 50000.

the rate at which the population increases is 5000 per year.

So, the increase for the first year will be 5000. And the population will be 55000.

Then again for the next year the growth will be 5000 and the population will be 50000 + (5000×2)
