Using the laws of logarithms, the value of x is 1024

We are given the equations:

log x = 1,000,000,000

log₂ x = 10

Using the definition of logarithms, we know that log x = y is equivalent to x = 10^y. Therefore, we can rewrite the given equations as:

x = 10^1,000,000,000

x = 2^10

We can use a calculator to find that 10^1,000,000,000 is an extremely large number (a "googol" is a 1 followed by 100 zeroes, and this number is much larger than a googol). However, we can simplify the expression x = 2^10 by calculating 2^10, which is 1024.

Each girl will receive the ratio of Girl 1: R2000, Girl 2: R3000 Girl 3: R7000

To find out how much each girl will get, we need to first add up the ratios:

Then, we can divide the total amount of money by the total ratio:

12000 ÷ 12 = 1000

This means that each "part" of the ratio is worth R1000.

To calculate how much each girl will get, we need to multiply their respective ratios by R1000:

Girl 1: 2 parts x R1000/part = R2000

The ladder will reach a height of 8 feet, which is greater than 7 feet. So, the ladder will indeed reach 7 feet high, and even higher.

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 area of the square whose side is the hypotenuse.

We can use the Pythagorean theorem to determine if the ladder will reach 7 feet high. Let's let x be the height that the ladder reaches, as shown in the diagram below:

According to the Pythagorean theorem, we have:

[tex]$\begin{align*}x^2 + 6^2 &= 10^2 &= 100 - 36 &= 64 \x &= \sqrt{64} \x &= 8\end{align*}[/tex]

Therefore, the ladder will reach a height of 8 feet, which is greater than 7 feet. So, the ladder will indeed reach 7 feet high, and even higher.

The reciprocal of the complex number [tex]\frac{\sqrt{2} }{2} - \frac{\sqrt{2} \ i }{2}[/tex] is determined as  [tex]\frac{\sqrt{2} }{2} + \frac{\sqrt{2} \ i }{2}.[/tex]

To find the reciprocal of a complex number, we need to divide 1 by the complex number. We can simplify the division by multiplying the numerator and denominator by the complex conjugate of the denominator.

The complex conjugate of

[tex]\frac{\sqrt{2} }{2} - \frac{\sqrt{2} \ i }{2}= \frac{\sqrt{2} }{2} + \frac{\sqrt{2} \ i }{2}[/tex]

So, the reciprocal of the complex number is:

[tex]\begin{aligned} \frac{1}{\frac{\sqrt{2} }{2} - \frac{\sqrt{2} \ i }{2}} &= \frac{1}{\frac{\sqrt{2} }{2} - \frac{\sqrt{2} \ i }{2}} \cdot \frac{\frac{\sqrt{2} }{2} + \frac{\sqrt{2} \ i }{2}}{\frac{\sqrt{2} }{2} + \frac{\sqrt{2} \ i }{2}} \ &= \frac{\frac{\sqrt{2} }{2} + \frac{\sqrt{2} \ i }{2}}{\frac{2}{2}} \ &= \frac{\sqrt{2} }{2} + \frac{\sqrt{2} \ i }{2} \end{aligned}[/tex]

Therefore, the reciprocal of the complex number;

Answer:

(x-6)(x-2)

Step-by-step explanation:

To factor, we use the quadratic formula, which gives us the roots of the equation. In an equation as ax²+ bx + c, we can use (-b±√(b^2-4ac))/2a. Since we have x² - 8x +12, a will be 1, b will be -8, and c will be 12.

(-(-8)±√((-8)²-4(1)(12))/2(1)

(8±√(64-48)/2

(8±√16)/2

(8±4)/2

We now have two cases: (8+4)/2 and (8-4)/2. We can solve these:

(8+4)/2 = 12/2 = 6

(8-4)/2 = 4/2 = 2

Since we have to factor this, we have to write it in the form of

(x-z)(x-y)

for z, we have 6, and for y, we have 2

(x-6)(x-2) is our final answer.

1. Find the length of DE. 2. Calculate the length of BD. 3. Add BD and EC to get AD.

To find the length of AD, the following steps can be followed:

1. To find the length of DE, the Pythagorean theorem can be used. It states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, the triangle is DEBC.

Therefore, DE2 = (12)2 + (10)2 = 144 + 100 = 244.

Taking the square root of 244 gives the length of DE as 15.722.

2. The length of BD can then be calculated as 12, since it is already given in the figure.

3. To find the length of AD, the lengths of BD and EC can be added together. That is, AD = BD + EC = 12 + 10 = 22.

Therefore, the length of AD is 22.

As the density of Mercury is higher than that of both Copper and Zinc, so both the new & old penny will float on mercury.

By dividing the object's mass by its volume, we may determine the density of metal.

Mass/volume equals density.

For ex, the object would have a density of 0.284 per cubic inch if its mass were 7.952 pounds and its volume were 28 cubic inches.

Now here in the given question,

Density of copper = 8.8g/cm³

Density of zinc = 7.2g/cm³

Here, both the densities are lesser than that of mercury.

Let's assume that the cone and cylinder have a radius of 'r' and a height of 'h'.

The volume of the cylinder is given by [tex]= \pi r^2h.[/tex]

The volume of the cone is given by V_cone = [tex](1/3)\pi r^2h.[/tex]

Therefore, we can simplify the volumes as V_cylinder = [tex]\pi r^2h[/tex] and V_cone = [tex](1/3)\pi r^2h.[/tex]

The ratio of the volume of the cone to the volume of the cylinder is then:

V_cone/V_cylinder = [tex]((1/3)\pi r^2h) / (\pi r^2h) = (1/3) / 1 = 1/3[/tex]

So, the volume of the cone is one-third of the volume of the cylinder.

The 85% confidence interval that the true mean number of words a third grader can read per minute is between 30.131 and 30.869.

To create a confidence interval for the mean number of words a third grader can read per minute, an educational psychologist wishes to know the mean number of words a third grader can read per minute. She intends to produce an estimate at an 85% level of confidence.

For a sample of 146 third graders, the mean words per minute read was 30.5. Assume a population standard deviation of 3.1.

To create a confidence interval, the following formula can be used:

µ±z_α/2*σ/√n

Here, we are given the following details:

Sample size: n = 146

Mean: µ = 30.5

Population standard deviation: σ = 3.1

Level of confidence: α = 1 - 0.85 = 0.15

We need to determine the critical value of z_α/2.

α/2 ⇒ 0.15/2 ⇒ 0.075

Using a standard normal distribution table, we find that the value of z_0.075 is 1.44.

Confidence Interval: µ ± z_α/2*σ/√n

⇒ 30.5 ± 1.44 × (3.1/√146)

⇒ 30.5 ± 0.369
