THE CORRECT ANSWER IS 57 CM³

Explanation:

Let's consider the vertical block first, having height 9 cm, length 1 cm, width 5 cm.

Hence the volume of that block = l.w.h = 9×5×1 = 45 cm³

Coming to the horizontal block, having height 4 cm, width 3cm, & length 1 cm.

Hence the volume of that block will be = 4×3×1 = 12 cm²

The total volume of irregular figure = Volume of vertical block + horizontal block = 45+12 = 57 cm³

Answer: Infinitely many solutions (ie set of all real numbers)

====================================================

Explanation:

First we subtract 7 from both sides

|x - 14| + 7 > 4

|x - 14| + 7-7 > 4-7

|x - 14| > -3

Recall that absolute value is never negative. So the |x-14| will never dip below zero.

In other words, the smallest |x-14| can possibly get is 0.

Because 0 > -3 is always true, this means |x − 14| > -3 is always true for any x value you pick.

Therefore, there are infinitely many solutions. The x value can be any real number.

The answer is not one of the options listed. The closest option is (a) 9 * 8 * 7 * 5, but this does not take into account the requirement that the last digit must be odd.

To solve this problem, we can use the multiplication principle, which states that if there are m ways to do one thing and n ways to do another thing, then there are m * n ways to do both things together.

First, we need to choose the last digit of the PIN to be odd. There are 5 odd digits to choose from (1, 3, 5, 7, and 9).

Next, we need to choose the first digit of the PIN. Since it cannot be the same as the last digit, there are only 9 choices left (since 0 is allowed as the first digit).

For the second digit, we can choose from 8 digits (we can't choose the first digit or the last digit, which leaves 8 choices).

For the third digit, we can choose from 7 digits (we can't choose the first digit, the second digit, or the last digit, which leaves 7 choices).

Therefore, the total number of choices for the PIN is:

5 * 9 * 8 * 7 = 2,520

So the answer is not one of the options listed. The closest option is (a) 9 * 8 * 7 * 5, but this does not take into account the requirement that the last digit must be odd.

Since M is the centroid of triangle ΔGHI, so KI = 10

The centroid of a triangle is the point at which the three medians of the triangle intersect.

In triangle ΔGHI, M is the centroid of the triangle. If HI = 20, we need to find KI. We proceed as follows.

We know that M is the centroid of the triangle and is the center point where the three medians of the triangle intersect.

Now, GK is a median which passes through HI at K.

Since GK is a median, this implies that HK = KI.

Also, HK + KI = HI

So, since HK = KI, we have that

HK + KI = HI

KI + KI = HI

2KI = HI

KI = HI/2

Given that HI = 20, substituting this into the equation, we have that

KI = HI/2

= 20/2

= 10

So, KI = 10

Answer:

There are a total of 10 + 15 + 25 = 50 marbles in the bag, and 10 of them are red. Therefore, the probability of Tammy selecting a red marble on any given draw is 10/50 = 1/5.

Since Tammy is returning the marble to the bag after each draw, the probability of selecting a red marble on any given draw remains the same. This means that each of the 90 draws is an independent event with a probability of 1/5 of selecting a red marble.

To find the expected number of times Tammy will select a red marble in 90 draws, we can use the formula:

Expected number of red marbles = Total number of draws x Probability of selecting a red marble on any given draw

Expected number of red marbles = 90 x 1/5

Expected number of red marbles = 18

Therefore, Tammy can expect to pull out a red marble approximately 18 times in 90 draws.

The horizontal distance from the base of the skyscraper out to the ship is 944.1 feet approximately.

You look straight parallel to ground. But when you have to watch something down, then you take your sight down by moving your head up. The angle from horizontal to the point where you stopped your head is called angle of depression.

See the figure where angle DAC is the angle when Nakeisha saw the boat from the top of the skyscrapper. It  is measured from the horizontal line AD.

For this case, referring to the figure attached below, we see that:

\(m\angle ACB = m\angle DAC = 51^\circ\) (because of them being alternate interior angles). (the small 'm' ahead of angles show that we're taking about measurement of angles).

Thus, using the tangent ratio from the perspective of \(\angle ACB\), we get:

\(\tan(\angle ACB) = \dfrac{|AB|}{|CB|}\\\\\\\tan(51^\circ) = \dfrac{1166}{x}\)

where |AB| denotes the length of the line segment AB.

From calculator, we get \(\tan(51^\circ) \approx 1.235\)

Thus, we get:

\(\tan(51^\circ) = \dfrac{1166}{x}\\\\1.235 \approx \dfrac{1166}{x}\\\\x \approx \dfrac{1166}{1.235} \approx 944.129 \approx 944.1 \: \rm ft\)

Thus, the horizontal distance from the base of the skyscraper out to the ship is 944.1 feet approximately.

The population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

To determine whether the population proportion who participated in voting or the sample proportion from the survey is higher, we need to compare the percentages.

The population proportion who participated in voting is given as 63% of all registered voters.

This means that out of every 100 registered voters, 63 participated in voting.

In the survey of retired voters, 162 out of 275 participants voted. To calculate the sample proportion, we divide the number of retired voters who participated (162) by the total number of retired voters in the sample (275) and multiply by 100 to get a percentage.

Sample proportion = (162 / 275) \(\times\) 100 ≈ 58.91%, .

Comparing the population proportion (63%) with the sample proportion (58.91%), we can see that the population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

Therefore, based on the given data, the population proportion who participated in voting is higher than the sample proportion from this survey.

It's important to note that the sample proportion is an estimate based on the surveyed retired voters and may not perfectly represent the entire population of registered voters.

Answer:

Step-by-step explanation:

the molecular formula is obtained by multiplying the empirical formula (CH) by the molecular formula ratio: Molecular formula = (CH) * 6 = C6H6

To determine the percent composition, empirical formula, and molecular formula of the substance, we need to use the given masses of the elements and the molecular mass.

a. Percent Composition:

The percent composition represents the proportion of each element's mass in the total mass of the substance.

For carbon:

Percent composition of carbon = (mass of carbon / total mass of substance) * 100

Percent composition of carbon = (43.910 g / 47.593 g) * 100

Percent composition of carbon ≈ 92.09%

For hydrogen:

Percent composition of hydrogen = (mass of hydrogen / total mass of substance) * 100

Percent composition of hydrogen = (3.683 g / 47.593 g) * 100

Percent composition of hydrogen ≈ 7.74%

Therefore, the percent composition of carbon and hydrogen in the substance is approximately 92.09% and 7.74%, respectively.

b. Empirical Formula:

The empirical formula represents the simplest ratio of the elements in a compound.

To determine the empirical formula, we need to find the mole ratios of the elements. First, we calculate the moles of each element using their masses and molar masses:

Moles of carbon = mass of carbon / molar mass of carbon

Moles of carbon = 43.910 g / 12.01 g/mol

Moles of carbon ≈ 3.659 mol

Moles of hydrogen = mass of hydrogen / molar mass of hydrogen

Moles of hydrogen = 3.683 g / 1.01 g/mol

Moles of hydrogen ≈ 3.649 mol

Next, we divide the number of moles of each element by the smallest number of moles to get the simplest ratio:

Carbon : Hydrogen ≈ 3.659 mol / 3.649 mol ≈ 1:1

The empirical formula of the substance is CH.

c. Molecular Formula:

To determine the molecular formula, we need the molecular mass of the substance.

The molecular mass is given as 78.11 u.

The empirical formula mass can be calculated by adding the molar masses of carbon and hydrogen:

Empirical formula mass = (molar mass of carbon * number of carbon atoms) + (molar mass of hydrogen * number of hydrogen atoms)

Empirical formula mass = (12.01 g/mol * 1) + (1.01 g/mol * 1)

Empirical formula mass = 13.02 g/mol

To find the molecular formula, we divide the molecular mass by the empirical formula mass and determine the whole-number ratio:

Molecular formula ratio = molecular mass / empirical formula mass

Molecular formula ratio = 78.11 g/mol / 13.02 g/mol

Molecular formula ratio ≈ 6

The answer is answer\[\tan^{-1}(2 i)=\frac{1}{2 i} \ln \left(\frac{i-1}{i+1}\right)\] and \[\cosh^{-1}(-1)\] is undefined.

Given,\[\tan^{-1} (2i)\]We know that tan(z) = i, where z is a complex number.

Therefore, we have\[\frac{e^{iz}-e^{-iz}}{i(e^{iz}+e^{-iz})}=i\]\[\Rightarrow\frac{e^{2iz}-1}{e^{2iz}+1}=-i\]\[\Rightarrow e^{2iz}+1 = i (e^{2iz}-1)\]\[\Rightarrow e^{2iz} = \frac{i-1}{i+1}\]Let, \[\frac{i-1}{i+1} = x + iy\]where x, y are real number.\[ \begin{aligned} \Rightarrow x + iy &=\frac{i-1}{i+1} \\ &=(i-1)(1-i) \\ &=\frac{(1-i)}{\sqrt{2}} \cdot \frac{(1+i)}{\sqrt{2}} \\ &=\frac{1}{2}(1+i) \cdot \frac{1}{2}(1-i) \\ &=\frac{1}{4}(2i) \cdot \frac{1}{4}(2) \\ &=\frac{1}{2} \cdot \frac{1}{2}i \\ &=\frac{1}{2}i^2 \\ &=-\frac{1}{2} \end{aligned} \]

Therefore, \[x = 0, y = -\frac{1}{2}\]\[\Rightarrow z = \frac{1}{2i}\ln \left(\frac{i-1}{i+1}\right)\]

Now, let's solve \[\cosh^{-1}(-1)\]We have,\[\cosh^{-1}x = \ln \left(x+\sqrt{x^{2}-1}\right)\]

Here, x = -1\[\Rightarrow \cosh^{-1}(-1)=\ln \left(-1+\sqrt{1-1}\right)\] As we know that,\[\sqrt{x^{2}-1}\]is undefined for x ≤ 1, so \[\cosh^{-1}(-1)\]is also undefined as \[\sqrt{1-1}=0\]

After considering the given data and given set of options we conclude that sequence projects a divergence therefore the correct option is diverges.  

To estimate and find whether the sequence \(an = 3 + 5n^2 / 1+n\) converges or diverges, we can apply the following steps:
We can apply divison of both the numerator and denominator of the sequence by \(n^2\) to get an equivalent expression: \(an = (5/n) + 3n / (1/n + 1).\)
As n comes towards infinity, the term 5/n approaches zero and the term 3n approaches infinity.
Hence, the sequence diverges to infinity.

The quadrant model of communication styles is based on the assumption that all people have a relatively consistent point on both the dominance and sociability continuums. This means that people tend to have a preferred communication style that is characterized by a particular combination of dominance and sociability. However, this does not mean that people fit into four discrete, unchanging categories that can be easily assessed by others.

The Laplace transform of the given function is F(s) = 25/(s^5) + 5/(s^4) e^(-s).

To find F(s), we need to take the Laplace transform of the given function. We have:

U(t – 1) = 1/s e^(-s)

Applying the product rule of Laplace transform, we get:

L{5t(5t + 1)U(t – 1)} = L{5t(5t + 1)} * L{U(t – 1)}

Now, we need to find the Laplace transform of 5t(5t + 1). We have:

L{5t(5t + 1)} = 5L{t} * L{5t + 1} = 5(1/s^2) * (5/s + 1/s^2)

Simplifying the expression, we get:

L{5t(5t + 1)} = 25/(s^4) + 5/(s^3)

Substituting L{5t(5t + 1)} and L{U(t – 1)} back into the original equation, we get:

F(s) = (25/s^4 + 5/s^3) * (1/s e^(-s))

Simplifying the expression further, we get:

F(s) = 25/(s^5) + 5/(s^4) e^(-s)
