What is geometric series?

Geometric series is an infinite series of the form:

\(a+ar+a r^{2} +ar^{3} +..........\)

where r is known as common ratio.

Now, first term is x and each term there after is twice the previous term.

So the series will be;

x , 2x , 4x , 8x, ..........

Clearly this series is geometric series with common ratio 2.

And the nth term of geometric series is \(ar^{n-1}\)

⇒ fifth term is 160

\(ar^{5-1} = 160\\ar^{4} = 160\\a 2^{4} =160\\a=\frac{160}{16} \\a=10\)

Here, first term is x.

The value of x in sequence of number is 10.

Answer:

1 bag of chips cost $1.25

Step-by-step explanation:

total money spent minus cost of soda = price of 2 bags of chips

$4.00- $1.50 = $2.50

2 bags of chips divided by 2 = price for one bag

$2.50 / 2 = $1.25

The concentration of the sodium chloride solution is 250,000 parts per million (ppm).

To calculate the concentration of the solution in parts per million (ppm), we need to determine the amount of solute (sodium chloride) present in relation to the total solution.

The concentration of a solution is typically expressed as the ratio of the mass of solute to the mass of the solution or the volume of solute to the volume of the solution. In this case, we have 0 grams of sodium chloride dissolved in 100 grams of solution.

To convert this into parts per million (ppm), we need to multiply the concentration by 1,000,000. Since ppm represents one part in a million, it is equivalent to mg/L or µg/g.

Using the given values, we have:

Concentration (ppm) = (mass of solute / mass of solution) * 1,000,000

Substituting the values, we get:

Concentration (ppm) = (0 grams / 100 grams) * 1,000,000

Concentration (ppm) = 0 * 1,000,000

Concentration (ppm) = 0

Therefore, the concentration of the solution is 0 parts per million (ppm), indicating that there is no sodium chloride present in the solution.

Alessia spent $5,408 on entertainment in 2021.

To determine how much Alessia spent on entertainment in 2021, we need to work backward from the given information about her salary in 2022.

Let's assume Alessia's salary in 2021 was the same as in 2022, which is $26,000 after tax.

Since Alessia spends 35% of her after-tax salary on rent, we can calculate her rent expenditure:

Rent = 35% × $26,000

= $9,100

The remaining amount is split between food, petrol, and entertainment in the ratio 6:11:8.

To determine the ratio's total parts, we sum the individual parts:

Total parts = 6 + 11 + 8 = 25

Next, we calculate the value of one part of the ratio:

One part = ($26,000 - $9,100) / 25

= $16,900 / 25

= $676

Now, we can calculate how much Alessia spent on entertainment in 2021, which is 8 parts of the ratio:

Entertainment expenditure = 8 × $676

= $5,408

Step-by-step explanation:

(a) a° +60°+35°=180 (sum of angles in a triangle)

a° +95° = 180

a° = 180-95 = 85°

(b) 80°+75°+ b° = ( sum of angles in a triangle )

155°+b° =180°

b= 180-155 =25°

(c) 61°+73°+c° = 180°

134° + c° = 180°

c° = 180-134= 46°

(d) since this is a right angled triangle

d°+ 37° + 90° = 180°

127°+ d° = 180°

d° = 180- 127= 53°

(e) 11°+132° +e° = 180°

143° + e° = 180

e° = 180-143 = 37°

(f) this is also a right angled triangle

44° +f° +90° 180°

134° + f° = 180

f ° = 180° - 144° = 36°

Given, Region bounded by y = x² + 1, y = 1 and x = 1Revolve the given region around the line x = 2We have to find the volume of the resulting solid obtained.Let's plot the given region below.

The given region and the axis of revolution can be seen below: We have to slice the given region perpendicular to the axis of revolution so that we get the discs for each slice.The discs obtained for each slice is shown below:We can write the volume of each disc obtained as:V = πr²hwhere, radius of each disc = (2 - x) and height of each disc = (y₂ - y₁)

When we revolve around the line x = 2, the axis of revolution, then the limits for x are: 1 ≤ x ≤ 2and the corresponding limits for y are: 1 ≤ y ≤ (x² + 1)So, we can write the volume of the resulting solid as:V = ∫₁²π(2 - x)²((x² + 1) - 1) dx= π ∫₁²(4 - 4x + x²)(x²) dx= π ∫₁²(4x² - 4x³ + x⁴) dx= π[4(2/3) - 4(1/4) + (1/5)] (Substitute limits of integration) = π[(8/3) - 1 + (1/5)]= (29π/15)

Therefore, the volume of the solid generated by revolving the region bounded by y = x² +1, y = 1 and x = 1 about the line x = 2 is (29π/15) cubic units.

The length of the base of the parallelogram is 10.25 inches.

given that,

the area of parallelogram=102 1/2 square inches

height=10 inches

The following formula determines the area of a parallelogram:

Base + height = area.

The parallelogram's area and height are provided. By entering these values in the above formula we obtain:

102 1/2 = base × 10

We can divide both sides by 10 to find the base:

102 1/2 ÷ 10 = base

By dividing 1 by 2, we may convert the mixed number 1/2 to a decimal:

102 1/2 ÷ 10 = 102.5 ÷ 10 = 10.25

therefore, the length of the base of the parallelogram is 10.25 inches long.

The claim that two situations are similar, despite major differences being ignored and only minor similarities being emphasized, is a fallacy known as false analogy.

False analogy is a logical fallacy that occurs when two situations are compared based on minor similarities while ignoring significant differences. It involves drawing an invalid or weak comparison between two unrelated or dissimilar things. In this fallacy, the person making the claim assumes that because two situations share some superficial similarities, they must be similar in all aspects. However, this overlooks the fundamental differences that make the situations distinct.

For example, if someone argues that banning the use of plastic bags in a city is similar to banning the use of cars, based solely on the fact that both involve restricting a common item, they would be committing a false analogy. While there may be minor similarities between the two situations, such as the concept of imposing restrictions, there are major differences in terms of environmental impact, necessity, and alternatives. Ignoring these significant differences leads to an invalid comparison and can result in flawed reasoning.

In conclusion, false analogy occurs when two situations are deemed similar based on minor similarities while disregarding major differences. It is essential to carefully evaluate the relevant factors and understand the nuances of each situation before drawing comparisons to ensure logical and valid arguments.

Using Ratio test we can say the series ∑ n=1 to infinity of \(n^2(-6)^n\) is convergent since the limit is less than 1 (specifically, it is equal to 1/6).

To determine whether the series ∑ n=1 to infinity of\(n^2(-6)^n\) is convergent or divergent, we can use the Ratio Test.

First, let's identify a_n, which represents the general term of the series. In this case, a_n =\(n^2(-6)^n.\)

Now, let's evaluate the limit as n approaches infinity of the absolute value of a_n+1 divided by a_n:

lim n→infinity (∣∣a_n+1 / a_n∣∣) = lim n→infinity (∣∣\((n+1)^2(-6)^(n+1) / (n^2\))\((-6)^n\)∣∣)

Simplifying the expression:

lim n→infinity (∣\((n+1)^2(-6)^(n+1) / (n^2)(-6)^n\)∣) = lim n→infinity (∣\((n+1)^2\) / \((n^2)(-6)\)∣∣)

Since the absolute value of -6 is 6, we can further simplify:

lim n→infinity (∣∣\((n+1)^2 / (n^2)(-6)\)∣∣) = lim n→infinity (∣∣\((n+1)^2 / (n^2)(6)\)∣∣)

Now, let's compute this limit:

lim n→infinity \(((n+1)^2 / (n^2)(6))\) = 1/6

Since the limit is less than 1 (specifically, it is equal to 1/6), the Ratio Test tells us that the series is convergent.

Therefore, the series ∑ n=1 to infinity of\(n^2(-6)^n\)is convergent.

\(V = 32\frac{5}{8}in^3\)

Step-by-step explanation:

Given

\(B = 14\frac{1}{2}in^2\) --- Base Area

\(h = 2\frac{1}{4}in\) --- Height

Required

Correct statement to calculate the volume of the box.

No options were given. So, the general explanation is as follows.

Given the base area and the height of the box, the volume is calculated by multiplying the given base area and the height.

So, we have:

\(Volume (V) = Base\ Area * Height\)

\(V = B *h\)

\(V = 14\frac{1}{2} * 2\frac{1}{4}\)

Convert to improper fractions

\(V = \frac{29}{2} * \frac{9}{4}\)

\(V = \frac{29*9}{2*4}\)

\(V = \frac{261}{8}\)

\(V = 32\frac{5}{8}in^3\)
