ln 1 is the converted from 2 ln 8-3 ln 4 to a single natural logarithm.
We need to convert 2 ln 8-3 ln 4 as a single natural logarithm.
First apply power property
⇒ ln 8² - ln 4³
⇒ ln 64 - ln 64
Now, applying quotient property
⇒ ln 64/64 = ln 1
Here, we finally converted 2 ln 8-3 ln 4 to a single natural logarithm ln 1.
What is natural logarithm?The inverse of an exponential function, the natural log is the logarithm to the base of the number e. Natural logarithms are unique varieties of logarithms that are employed in the treatment of time and growth-related issues.
The distinction between log and ln is that log is expressed in terms of base 10, while ln is expressed in terms of base e. As an illustration, log of base 2 is denoted by log2 and log of base e by loge = ln (natural log).

When a number is decreased by 10% of itself, the result is 81, what is the number?
The number is 90.
What is the number?
Percentage can be described as the fraction of an amount that is expressed as a number out of hundred. The sign used to represent percentage is %. Percentages are a measure of frequency.
When the number is decreased, the number becomes smaller. This means that the original number is larger than 81.
The equation that can be used to represent the information in the question is:
(1 - percentage decrease) initial number = 81
(1 - 0.1)x = 81
0.9x = 81

What is Logarithm?The opposite of exponentiation is the logarithm.This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.Now,
As seen by the definition of logarithms, [tex]log_b(a)=x[/tex]
In case of natural logarithm, b = e, i.e., [tex]log_e(a)=x[/tex] = ln (a) = x
In the given expression, a = e
Hence, ln (e) = x
By properties of logarithms, we get that: ln (e) = 1.
Hence, ln (e) = 1, by the properties of logarithm.

The value of x in the angles is 14.
How to find angles when parallel lines are cut by transversal?When parallel lines are cut by a transversal, angle relationships are formed.
The angle relationships that are formed includes corresponding angles, alternate angles, vertical angle etc.
Therefore, the value of x can be found as follows;
m∠1 = m∠7 (vertical angles)
Therefore,
m∠7 = m∠15(corresponding angles)
Hence,
m∠1 = m∠15
m∠1 = 8x - 4
m∠15 = 6x + 24
Therefore,
8x - 4 = 6x + 24
8x - 6x = 24 + 4
2x = 28
divide both sides by 2
x = 28 / 2

The first 4 terms of the geometric sequence are 12 , 36 , 108 and 324.
In a geometric sequence, each term following the first is found by multiplying the preceding one by a constant, non-zero quantity known as the common ratio.
The nth term of a geometric series with first term a and common ratio r is given by [tex]a_n=ar^{n-1}[/tex] .
Given the first term of the geometric sequence is 12 .
And given [tex]a_n=a_{n-1}\times 3[/tex]
Now using the above formula:
a₂ = a₁ × 3
or, a₂ = 12 × 3 = 36
Again using the above formula:
a₃ = a₂ × 3
or, a₃ = 36×3 = 108
Similarly
a₄ = a₃ × 3
or, a₄ = 108 × 3 = 324
Hence the first four terms of the geometric sequence are 12 , 36 , 108 and 324 .

Point G is the center of the small circle. Point X is the center of the large circle. Points G, H, and X are all on line segment GX.
what should be the area of a new circle that has a line segment GX as the diameter
The area of a new circle that has line segment GX as its diameter is 121 pi cm² .
Suppose that,
The radius of the small circle (GH) = 10 cm.
The radius of the big circle (HX) = 12 cm.
We will add the line GH and HX to get the total length of line segment GX.
So, GX = GH + HX
= 10 + 12
GX = 22 cm.
So, the diameter of new circle will be equal to line segment GX as it is given in the question.
Then, the area of new circle = π r² ( r = radius)
Radius = D/2 = 22/2 (D = Diameter)
r = 11
Now, Area = π × 11²

The value given expression of (x⁵ + 8)/(x + 1) is (x⁶ + 8x).
What is termed as indices/index?In mathematics, an index (indices) is the power but rather exponent raised to the a number or variable. In number 2⁴, for example, 4 is the index of 2. Indexes is the plural form of index. We encounter constants and variables in algebra. A constant is just a value that cannot be altered. A variable quantity, on the other hand, can be assigned such a number or have its value changed.The given expression is-
(x⁵ + 8)/(x + 1) .......equation 1
It is stated that;
x² + x = 1
Taking x common;
x(x + 1) = 1
Bring x on the other side.
(x + 1) = 1/x
Put the value of (x + 1) in equation 1.
= (x⁵ + 8)/(x + 1)
= (x⁵ + 8)/[1/x]
Simplifying;
= (x⁵ + 8)x
Multiplying x on both values;
= x⁵x + 8x
= x⁶ + 8x
Thus, the value of the given expression is (x⁶ + 8x).

The required value of sports imports of the United States in 2012 is $2,745,240,000,000.
.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
the total value of exports from the United States in 2012 = $2,210,585,000,000
Now it is also given that,
the total value of exports from the United States in 2012 = $837,965,000,000 more than half of the US imports
Therefore, we can write
the total value of exports from the United States in 2012 = $837,965,000,000 + imports/2
Putting the value of exports we get,
2,210,585,000,000 = 837,965,000,000 + imports/2
Taking alike terms together we get,
Imports/ 2 = 2,210,585,000,000 - 837,965,000,000
Solving we get,
Imports/ 2 = 1,372,620,000,000
Multiplying by 2 both the side by 2 we get,
Imports = 2,745,240,000,000
Thus, the value of imports of the United States in 2012 = $2,745,240,000,000
Thus, the required value of imports of the United States in 2012 is $2,745,240,000,000.

numbers like 2%, 3%, 4% and 6% are often used to represent the grade of a road. such a number tells how steep a road is. 3% grade means that for every horizontal distance of 100 ft, the road rises or descends 3 feet. in each of the following cases, find the road grade to two decimal places.
(a) Grade = 2.86%
(b) Grade = 5.85%
What is the horizontal distance?The projectile's horizontal range is the distance it travels while in flight. Since there is no acceleration in the horizontal direction, the greatest distance traveled in the horizontal direction is what this definition means.Vertical distance is the distance following the direction of gravity, and horizontal distance is the distance along the ground surface. The distance between a building and the observer is an example of a horizontal distance, and the building's height is an example of a vertical distance.Anything that forms a 90-degree angle (right angle) with the horizontal or the horizon is referred to as vertical because it is the opposite of the horizontal. The line that spans from left to right is therefore considered horizontal.By the angle's tangent, multiply the object's height. Let's assume, for the purposes of this illustration, that the item is 150 feet tall. The product of 150 and 1.732 is 86.603. 86.603 feet separate you from the thing horizontally.Find the road grade to two decimal places:
Grade in terms of percentage = (rise/run) * 100%

Determine whether the vectors in each pair are normal to each other. (6,-3) and (2,4).
Since their dot product is zero, then (6,-3) and (2,4) are normal to each other.
Step-by-step explanation:
Two vectors are said to be normal or perpendicular to each other if the result of their dot product is equal to zero.
These two vectors are also called orthogonal to each other.
Let u = (u₁, u₂) and v = (v₁, v₂), then the dot product u . v is defined as:
u . v = u₁v₁ + u₂v₂
To check whether the vectors are normal to each other, let us check their dot product.
The given vectors are: (6,-3) and (2,4).
Let u = (6, -3) and v = (2, 4), then,
