The length of the midsegment of 28. is 17 units and 29. is 27 units.

A line drawn by joining the midpoints of any two of the triangle's sides is known as the midsegment. All three sides of a triangle can be divided in half, with the midpoint being the point that is equally spaced from either vertex, regardless of whether the triangle is a right triangle, isosceles triangle, or sometimes an equilateral triangle.

If the slope and sides are same then we can cut the midsegment ad paste it such that it becomes an rectangle.

28. Now the length of the rectangle = n + 12 + n + 12 = 4n + 6 + 2n - 2

⇒ 2n + 24 = 6n +4

⇒ 20 = 4n

⇒ n = 20/4

⇒ n = 5

Length of midsegment = 5 + 12

                                       =  17 units

29. Now the length of the rectangle = 2n+ 11 + 2n+ 11 = 5n - 2 + n + 8

⇒ 4n + 22 = 6n + 6

⇒ 16  = 2n

⇒ n = 16/2

⇒ n = 8

Length of midsegment = 2(8) + 11

                                       =  27 units

Thus, he length of the midsegment of 28. is 17 units and 29. is 27 units.

To compute the Laplace transform of a function, we use the integral definition , F(s) = L{f(t)} = ∫ f(t) e^(-st) dt.

What is integral definition ?

The integral definition of the Laplace transform is a mathematical method used to find the Laplace transform of a function. It is defined as,

F(s) = L{f(t)} = ∫ f(t) e^(-st) dt , Where F(s) is the Laplace transform of the function f(t), s is a complex variable known as the frequency domain variable, and t is the time domain variable.

Given the functions f(t) provided ,

f(t) = e^(-8t)sin(5t)

F(s) = L{e^(-8t)sin(5t)} = ∫ e^(-8t)sin(5t) e^(-st) dt = (5/(s+8+5i))(e^(-8-s)) - (5/(s+8-5i))(e^(-8-s))

f(t) = e^(-st)sinh(7t)

F(s) = L{e^(-st)sinh(7t)} = ∫ e^(-st)sinh(7t) e^(-st) dt = (7/(s^2+49))(e^(-s-7i)) - (7/(s^2+49))(e^(-s+7i))

f(t) = -7t cosh(5t)

F(s) = L{-7t cosh(5t)} = ∫ -7t cosh(5t) e^(-st) dt = (-7/s^2)(e^(-s-5)) - (7/s^2)(e^(-s+5))

f(t) = 9t sin(ut)

F(s) = L{9t sin(ut)} = ∫ 9t sin(ut) e^(-st) dt = (9/(s^2 + u^2))(e^(-su)) - (9/(s^2 + u^2))(e^(su))

Note that in all cases, we should check if the integral converges, and that the limits of integration are appropriate.

Answer:

5509 yes votes

Step-by-step explanation:

We will start by adding together our ratio, so we know how many voters there were in a total ratio, so we can divide our total number of people by it, and then multiply it by the number of people who said yes (7 people).

Our ratio was 7:4, so adding those two numbers together gives us 11. Then, dividing 8657 by 11 gives us:

8657 / 11 = 787

Now, we will multiply 787 by 7, since that was the number of people who said yes:

787 * 7 = 5509

So, there were 5509 yes votes.

Researchers frequently select a level of significance of 0.05. The reason for this is that if we chose a lower threshold of significance, we will have less room to reject the null hypothesis and so a higher likelihood of making a type 2 error.

On the other hand, if the degree of significance is higher, more type 1 errors are made, leading us to reject the hypothesis even though it is correct. Therefore, 0.05 is a balanced level that is neither significantly greater nor significantly smaller. The health care and nutrition-related industries are mostly included in some of the studies where we require a lower level of importance. This type of industry has a higher error rate, which causes more fatalities and negative side effects.

We can use a higher level of relevance in a variety of circumstances, such as the entertainment and marketing-related industries. The reason for this is that even if there are more potential for error, it won't harm the person; instead, it just affects the information, which we can assess using common sense.

Answer:

-35/24

Step-by-step explanation:

5/8 - (3 - 1/4) + 2/3 =

Distribute the negative sign to 3 and -1/4. When a negative sign is distributed to a negative number, that number becomes positive:

- (3 - 1/4)  ==> -3 + 1/4

5/8 - 3 + 1/4 + 2/3 =

Now multiply the equation by 24/24 = 1. Multiplying anything by 1 results in the same equation. For example, 8 * 1 = 8.

Also multiply the equation by 24/24 because 24 is the LCM (Least Common Multiple) of the denominators 8, 4, and 3: 8*3=24. 6*4=24.

(5/8 - 3 + 1/4 + 2/3) * 24/24 =

(5*24/8 - 3*24 + 1*24/4 + 2*24/3) / 24 = ==> multiply each term by 24 and

                                                                    divide the entire expression by 24

(120/8 - 72 + 24/4 + 48/3) / 24 = ==> simplify

The value of the numerical expression 5/8 - (3 - 1/4) + 2/3 is -35/24.

When used to represent a quantity or a mathematical relationship, symbols and numbers are combined to form an expression in mathematics. It may contain exponents, brackets, variables, constants, and mathematical operations like addition, subtraction, multiplication, and division.

To simplify the expression 5/8 - (3 - 1/4) + 2/3, we need to follow the order of operations (also known as PEMDAS):

First, we need to simplify the expression inside the parentheses (3 - 1/4):

3 - 1/4 = 12/4 - 1/4 = 11/4

Next, we need to subtract 11/4 from 5/8:

5/8 - 11/4 = 5/8 - 22/8 = -17/8

Finally, we need to add 2/3 to the result:

-17/8 + 2/3

To add these two fractions, we need to find a common denominator. The least common multiple of 8 and 3 is 24, so we can rewrite the fractions with a denominator of 24:

-17/8 + 2/3 = (-51/24) + (16/24) = -35/24

Answer: If Pedro starts reading at page 20 and reads at an average rate of 25 pages per hour, and Bella starts reading at the same time but starts at page 60 and reads at an average rate of 18 pages per hour,

We can use the formula: distance = rate x time

To find out when they will meet we need to find out when they are on the same page.

let's say t be the time in hours, Pedro will be reading t25 pages, and Bella will be reading t18 pages.

So we can write the equation: 20+t25 = 60+t18

Solving this equation we get t = 2

So, they will meet after 2 hours.

Pedro will be on page 20+225 = 70, and Bella will be on page 60+218 = 96

So they will meet at page 70 when Pedro reaches that page after 2 hours of reading, which means Bella will have read 26 pages more than Pedro on that point.

Since the points on this graph represent a relationship between x- and y-values, a statement about the relationship which is true include the following: A, it cannot be proportional because the straight line through the points does not go through the origin.

In Mathematics, the graph of any proportional relationship between two (2) variables is always characterized by a straight line with the data points starting from the origin (0, 0) and passes through other unique data points on the cartesian coordinate.

By critically observing the graph which shows a relationship between the x-values and y-values, we can logically deduce that it does not start from the origin (0, 0) and as such, it does not represent a proportional relationship.

Therefore, the missing side (a) is 11.18 m.

We are trying to find the missing side (a) of the triangle shown in the diagram.

To do this, we will use the Pythagorean Theorem, which states that the sum of the squares of the two shorter sides of a right triangle is equal to the square of the longest side.

The two shorter sides of the triangle are 5 m and 10 m.

We will use the Pythagorean Theorem to calculate the missing side (a).

First, we need to square the lengths of the two shorter sides:

5² = 25

10² = 100

Next, we add the squares of the two shorter sides together:

25 + 100 = 125

Finally, we take the square root of the sum to find the length of the missing side:

[tex]a=7[/tex]

Step-by-step explanation:

The legs of an isosceles right triangle are congruent.

The Pythagorean Theorem may be used to calculate the length of side a: [tex]a^{2}[/tex] = 72 + [tex]b^{2}[/tex] = 49 + [tex]b^{2}[/tex]. When we solve for a, we obtain a = (49 + [tex]b^{2}[/tex]). As a result, the length of side an equals the square root of 49 multiplied by the square of side b.

The Pythagorean Theorem is a mathematical equation that asserts that the square of the length of the hypotenuse (the side opposite the right angle) in a right triangle is equal to the sum of the squares of the other two sides. The Pythagorean Theorem is stated in equation form as [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex], where a and b are the lengths of the triangle's legs (the two sides that meet at a right angle) and c is the length of the hypotenuse.
