Step-by-step explanation:

Let f(x) = lnx and g(x) = log₂x. for all 0 < x < 1, f(x) < g(x): True.

In this scenario and exercise, we would determine the corresponding output value for the functions f(x) and g(x) under the given mathematical operation and independent variables.

When x = 1, the output value for f(x) based on the table of values is given by;

f(x) = lnx

f(1) = ln(1).

f(1) = 0.

When x = 2, the output value for f(x) based on the table of values is given by;

f(x) = lnx

f(2) = ln(2).

f(2) = 0.69314718

When x = 1, the output value for g(x) based on the table of values is given by;

g(x) = log₂x

g(1) = log₂(1)

g(1) = 0.

When x = 2, the output value for g(x) based on the table of values is given by;

g(x) = log₂x

g(2) = log₂(2)

g(2) = 1.

In this context, we can logically deduce that the function f(x) is less than function g(x) for all 0 < x < 1.

Answer:

where is the pic............

Answer: 18.18%

Step-by-step explanation:

First, let's calculate the surface area of the original piece of wood. The surface area (SA) of a rectangular prism is given by the formula:

\($$SA = 2lw + 2lh + 2wh$$\)

where \(\(l\)\) is the length, \(\(l\)\) is the width, and \(\(h\)\) is the height. For the original piece of wood, \(\(l = 10\) inches\), \(\(w = 4\) inches\), and \(\(h = 5\) inches\).

After the piece of wood is cut in half, the length becomes 5 inches, but the width and height remain the same. So, for each of the two new pieces of wood, \(\(l = 5\) inches\), \(\(w = 4\) inches\), and \(\(h = 5\) inches\). The total surface area of the two new pieces of wood is twice the surface area of one of the new pieces.

The percent increase in the total surface area is given by the formula:

\($$\text{Percent Increase} = \frac{\text{New Total SA} - \text{Original SA}}{\text{Original SA}} \times 100\%$$\)

Let's calculate these values.

The percent increase in the total surface area when the piece of wood is cut in half is approximately 18.18%.

To calculate your available credit, you need to subtract your current balance and the amount of cash advance you want from your credit limit:

Available credit = credit limit - current balance - cash advance amount

Given that your credit limit is $7,500 and your current balance is $2,200, the available credit can be calculated as follows:

Available credit = $7,500 - $2,200 - cash advance amount

Now, if you want a cash advance of $1,000, for example, your available credit will be:

Available credit = $7,500 - $2,200 - $1,000 = $4,300

Therefore, your available credit is $4,300 if you want a cash advance of $1,000.

To calculate the transaction fee, you need to multiply the cash advance amount by the transaction fee percentage. In this case, the transaction fee is 2.5%. So, if you want a cash advance of $1,000, the transaction fee will be:

Transaction fee = $1,000 x 0.025 = $25

Therefore, if you want a cash advance of $1,000, you will owe a transaction fee of $25. It's important to note that cash advances usually come with a higher interest rate than regular credit card purchases, so it's best to use them only when absolutely necessary and pay them off as soon as possible to avoid accruing interest charges.

By using Pythagoras theorem we get the height of the roof of dog house is 21 inches.

The Pythagoras theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. 

This theorem is named after the Greek philosopher Pythagoras, who lived around 570 BC. born. 

According to the question:

Given, Hypotenuse(h) = 29 inches

           Base(b) = 40/2 = 20 inches

Using Pythagoras theorem, we get

h² = b² + p²

⇒ 29² = 20² + p²

⇒ p² = 29² - 20²

⇒ p² = 841 - 400

⇒ p² = 441

⇒ p = √441

⇒ p = 21

∴ The height of the roof of dog house is 21 inches.

Answer:

Step-by-step explanation:

56

We need to round up to the next higher integer, the sample size required to estimate the mean with an error of +4 and 95 Percent confidence is 170.

To find the sample size to estimate the mean with an error of +4 and 95 percent confidence, we need to use the formula:

n = [(z*sigma)/E]^2

Where:
n = sample size
z = z-score for 95% confidence level (which is 1.96)
sigma = standard deviation (unknown in this case)
E = maximum allowable error (which is +4 in this case)

We are given that o=12, which is the population standard deviation. Since we do not have any information about the sample standard deviation, we can use the population standard deviation as an estimate. Therefore, we can substitute o=12 in the above formula to get:

n = [(1.96*12)/4]^2
n = 169.64

Since we need to round up to the next higher integer, the sample size required to estimate the mean with an error of +4 and 95 percent confidence is 170.

Answer:

Who knows!?

Step-by-step explanation:

Answer:

A. 70.69 is the correct answer.

Step-by-step explanation:

Given:

Two lines:

\(3x - 4y + 5 = 0 \\2x + 3y -1 = 0\)

To find:

Angle between the two lines = ?

Solution:

Acute Angle between two lines can be found by using the below formula:

\(tan \theta = |\dfrac{(m_1 - m_2)}{ (1 + m_1m_2)}|\)

Where \(\theta\) is the acute angle between two lines.

\(m_1, m_2\) are the slopes of two lines.

Slope of a line represented by \(ax+by+c=0\) is given as:

\(m = -\dfrac{a}{b }\)

So,

\(m_1 = -\dfrac{3}{- 4} = \dfrac{3}{4}\)

\(m_2 = -\dfrac{2}{ 3}\)

Putting the values in the formula:

\(tan \theta = |\dfrac{(\dfrac{3}{4}- (-\dfrac{2}{3}))}{ (1 + \dfrac{3}{4}\times (-\dfrac{2}{3 }))}|\\\Rightarrow tan \theta = |\dfrac{\dfrac{3}{4}+\dfrac{2}{3}}{ (1 -\dfrac{1}{2})}|\\\Rightarrow tan \theta = |\dfrac{\dfrac{17}{12}}{ \dfrac{1}{2}}|\\\Rightarrow tan \theta = \dfrac{17}{6}\\\Rightarrow \theta = tan^{-1}(\frac{17}{6})\\\Rightarrow \theta = \bold{70.69^\circ}\)

Answer:

See Explanation

Step-by-step explanation:

(a) Proof: Product of two rational numbers

Using direct proofs.

Let the two rational numbers be A and B.

Such that:

\(A = \frac{1}{2}\)

\(B = \frac{2}{3}\)

The product:

\(A * B = \frac{1}{2} * \frac{2}{3}\)

\(A * B = \frac{1}{1} * \frac{1}{3}\)

\(A * B = 1 * \frac{1}{3}\)

\(A * B = \frac{1}{3}\)

Proved, because 1/3 is rational

(b) Proof: Quotient of a rational number and a non-zero rational number

Using direct proofs.

Let the two rational numbers be A and B.

Such that:

\(A = \frac{1}{2}\)

\(B = \frac{2}{3}\)

The quotient:

\(A / B = \frac{1}{2} / \frac{2}{3}\)

Express as product

\(A / B = \frac{1}{2} / \frac{3}{2}\)

\(A / B = \frac{1*3}{2*2}\)

\(A / B = \frac{3}{4}\)

Proved, because 3/4 is rational

(c) x + y is rational (missing from the question)

Using direct proofs.

Let x and y be

Such that:

\(x = \frac{1}{2}\)

\(y = \frac{2}{3}\)

The sum:

\(x + y = \frac{1}{2} + \frac{2}{3}\)

Take LCM

\(x + y = \frac{3+4}{6}\)

\(x + y = \frac{7}{6}\)

Proved, because 7/6 is rational

The above proof works for all values of A, B, x and y; as long as they are rational values

Answer:

Step-by-step explanation:

B is the least expensive

Using the normal distribution, it is found that:

a) The percentage of pregnancies lasting between 265 and 275 days is of 20.52%.

b) The longest 25% of the pregnancies last at least 276 days.

c) The distribution is approximately normal, with mean of 264 days and the standard deviation of 2.85 days.

d) The probability that the mean is less than 267 days is of 0.8531 = 85.31%.

The z-score of a measure X of a variable that has mean symbolized by \(\mu\) and standard deviation symbolized by \(\sigma\) is given by the rule presented as follows:

\(Z = \frac{X - \mu}{\sigma}\)

The mean and the standard deviation of pregnancy lengths are given, respectively, by:

\(\mu = 264, \sigma = 18\)

The proportion between 265 and 275 is the p-value of Z when X = 275 subtracted by the p-value of Z when X = 265, hence:

X = 275:

\(Z = \frac{X - \mu}{\sigma}\)

Z = (275 - 264)/18

Z = 0.61

Z = 0.61 has a p-value of 0.7291.

X = 265:

\(Z = \frac{X - \mu}{\sigma}\)

Z = (265 - 264)/18

Z = 0.06

Z = 0.06 has a p-value of 0.5239.

0.7291 - 0.5239 = 0.2052 = 20.52% is the percentage.

The longest 25% of pregnancies last at least the 75th percentile, which is X when Z = 0.675, hence:

\(Z = \frac{X - \mu}{\sigma}\)

0.675 = (X - 264)/18

X - 264 = 0.675 x 18

X = 276 days.

For the sample of 40 women, the standard deviation is given as follows:

\(s = \frac{18}{\sqrt{40}} = 2.85\)

For item d, the probability is the p-value of Z when X = 267, hence:

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem

\(Z = \frac{X - \mu}{s}\)

\(Z = \frac{267 - 264}{2.85}\)

Z = 1.05

Z = 1.05 has a p-value of 0.8531.

Assume that the duration of human pregnancies can be described by a normal model with a mean 264 days and a standard deviation 18 days.
