find the 4th partial sum, s4, of the series [infinity] n−2 n=9 s4 =

Answer:

23.5 it is hard to see the little dashes

Step-by-step explanation:

The hypothetical value of the sum of the geometric series is 1

The first term that we have in this progression is given as 1/2. Next we have to find the common ratio that lies between the values.

The sum of the infinite geometric series can be gotten by

a / (1 -r)

where a is the first term in the series = 1/2

r is the common ratio of the progression = 1/2

we would have to input the values. such that we would have:

1/2 / (1- 1/2)

(1/2) / (1/2)

= 1

The sum of the series is 1.

The points on the graph of f(x) = log9x are (20, 4.5), (11/9, 0.087183), (2439, 3.168910), (181, 2.55231), and (2, 1).

The points on the graph of f(x) = log9x can be calculated by substituting the given values of x in the equation. For example,

f(-1/81) = log9(-1/81) = log9(-1) - log9(81) = undefined

f(20) = log9(20) = log9(2*2*2*5) = log9(2) + log9(2) + log9(2) + log9(5) = 1 + 1 + 1 + 1.5 = 4.5

f(11/9) = log9(11/9) = log9(11) - log9(9) = 1.041393 - 0.954210 = 0.087183

f(-13) = log9(-13) = log9(-1) - log9(13) = undefined

f(2439) = log9(2439) = log9(3*13*37) = log9(3) + log9(13) + log9(37) = 0.477121 + 1.11394 + 1.579789 = 3.168910

f(181) = log9(181) = log9(3*3*7*7) = log9(3) + log9(3) + log9(7) + log9(7) = 0.477121 + 0.477121 + 0.84509 + 0.84509 = 2.55231

f(2) = log9(2) = log9(2) = 1

Hence, the points on the graph of f(x) = log9x are (20, 4.5), (11/9, 0.087183), (2439, 3.168910), (181, 2.55231), and (2, 1).

After 50 hours,  Plan B be more profitable than Plan A for the painter

What is linear inequation?

Inequation shows the comparision between two algebraic expressions by connecting the two algebraic expressions by >, <, ≥, ≤

A one degree inequation is known as linear inequation.

Here, a linear inequation needs to be solved

Let after t hours,  Plan B be more profitable than Plan A for the painter

For plan A

A painter Charges $500 plus $45 per hour

Cost after t hours = $(500 + 45t)

For plan B

A painter Charges  $55 per hour

Cost after t hours = $55t

By the problem,

55t > 500 + 45t

Step-by-step explanation:

A hypothesis test involves a comparison between research results from a sample and a hypothesis about a population.

Thus, option (A) is correct.

In hypothesis testing, a researcher starts with a null hypothesis, which represents the assumption of no difference or no effect in the population.

The researcher collects data from a sample and performs statistical analysis to determine whether the evidence supports or rejects the null hypothesis in favor of an alternative hypothesis.

The research results obtained from the sample are compared to the hypothesis about the population to determine whether there is enough evidence to reject the null hypothesis and accept the alternative hypothesis.

The lengths in the scale drawing are smaller than the corresponding lengths in the original figure.

When the scale factor is less than 1, the image of a shape will be reduced in size compared to the original shape. This means that all dimensions of the shape will be scaled down by the same factor. For example, if a shape is scaled down by a factor of 0.5, its length, width, and height will all be half the size of the original shape. Additionally, the area and volume of the image shape will be scaled down by the square and cube of the scale factor respectively.

In other words, when the scale factor is between 0 and 1 it will be a reduction and if it's greater than 1 it will be an enlargement.

As can be seen from the question, the scale factor is less than one as it is 1 / 3. This means that the lengths on the scale drawing would be smaller than the lengths on the original drawing.

We can start by using the following equation to determine the number of yards of red fabric r she will need for each costume:

1 + r = y (y represents the total number of yards of fabric for each costume)

We know that the total number of yards for all the costumes is 8 and there are 5 costumes, so we can use this information to set up another equation:

5y = 8 (y represents the total number of yards of fabric for each costume)

Now we can substitute the first equation into the second equation to get:

5(1 + r) = 8

Expanding the left side of the equation:

5 + 5r = 8

Subtracting 5 from both sides:

5r = 3

Dividing both sides by 5:

r = 3/5

So, Mrs. Byers will need 3/5 yards of red fabric for each costume.

Answer:

Step-by-step explanation:

the nth term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

the first term a₁ from the table below n = 1, a₂ below n = 2 and so on

here a₁ = 100 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{-50}{100}[/tex] = - [tex]\frac{1}{2}[/tex] , then

[tex]a_{n}[/tex] = 100 [tex](-\frac{1}{2}) ^{n-1}[/tex]

During exercise, there was a substantial link between heart rate, coronary flow, and cardiac oxygen consumption. As heart rate increases, so does oxygen consumption, which seems to reach a maximum at very fast heart rates.

Your pulse and heart rate both serve as indicators of how your heart is working. Your heart rate is the number of times it beats in a minute. Your arteries widen as a result of the number of times your heart beats every minute.

In healthy people, heart rate, workload, and oxygen consumption are all linearly connected up to a certain point. The heart's reaction to physical exercise or stress is considered to be controlled by the sympathetic nervous system.

Yes, it is possible to form a triangle with sides of 3.5cm, 4.5cm, and 7.5cm. This is because these triangle's sides adhere to the triangle inequality theorem.

The triangle inequality theorem which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. This is because in order to form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side, otherwise it would be impossible to connect the three sides and form a closed shape.

In this case,

3.5 cm + 4.5 cm = 8 cm > 7.5 cm

3.5 cm + 7.5 cm = 11 cm > 4.5 cm

4.5 cm + 7.5 cm = 12 cm > 3.5 cm

Longitudes: The vertical lines running north-south, join the two poles. They are called the meridians of longitude. They are spaced farthest apart at the equator and converge at a point at each pole.

Horizontal lines called latitudes are used to measure distances north or south of the equator. Vertical lines known as longitudes are used to determine the west or east of the meridian in Greenwich, England. Latitude and longitude work together to help cartographers, geographers, and others find specific locations on the globe.

What is the uses of latitude?

Any location's distance from the equator may be determined using its latitude, which is based on its degree. We can locate any point on Earth using longitude and latitude. The GPS or Global Positioning System uses these coordinates.

The grid system that enables us to locate absolute or precise places on the surface of the Earth is made up of latitude and longitude. Latitude and longitude can be used to pinpoint certain locations. Landmark identification also benefits from knowledge of latitude and longitude.

The triangle formed by sides 24, 25 and 5 cm is not a right angled triangle.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Let us consider the triangle is a right angle triangle
