What is a natural logarithm?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.
Typically, the natural logarithm of x is denoted by the symbols ln x, loge x, or, if the base e is implicit, just log x. When adding parentheses for clarity, the values ln(x), loge(x), or log (x). In order to avoid ambiguity, this is notably done when the argument to the logarithm is not a single symbol.
The power to which e would need to be raised in order to equal x is the natural logarithm of x.
For instance, e2.0149... = 7.5, thus ln 7.5 equals 2.0149.
Since e1 = e, the natural logarithm of e itself, or ln e, is equal to 1, while the natural logarithm of 1 is 0, since e0 = 1.

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:

Solve the following radical equations.
√(x+3) = 4√x-2
The solution for the radical equation √(x+3) = 4√x-2 is 7 / 3.
The phrase "algebraic expression" refers to any arrangement of terms that have undergone operations like addition, subtraction, multiplication, division, etc. (or variable expression).. Let's use the equation 5x + 7 as an example. Thus, 5x + 7 is an illustration of an algebraic expression.
Eliminate the radical on the both sides by squaring on both sides-
Both sides must be raised to the second power.
√(x+3) ²=(4√x-2 )²
After squaring we get
x+3=16(x-2)
Solving the equation-
We get rearranged equation as :
x+3=16x-32
15x=35 x=35/15 which further reduces to 7/3 .
Check if the solution is correct by putting it in original equation-
putting x=7/3 in the equation √(x+3) = 4√x-2
we get √16/3=√16/3
Therefore, the solution for the radical equation √(x+3) = 4√x-2 is 7 / 3.

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

How to Solve and Evaluate Equations?To solve for a variable in an equation, we need to isolate the variable to one side of the equation.
A. a = b/c²
a(c²) = b/c²(c²) [multiplication property of equality]
ac² = b
b = ac² (dark green)
Substitute a = 1/8 and c = 4 into the equation
b = (1/8)(4²)
b = (1/8)(16)
b = 2
B. m - v = k
m - v - m = k - m [subtraction property]
-v = k - m
v = -k + m
v = m - k (light blue)
Substitute k = -7 and m = -2 into the equation
v = -2 - (-7)
v = -2 + 7
v = 5
C. p/q = r/s
Cross multiply
qr = ps
qr/r = ps/r [division property]
q = ps/r (yellow)
Substitute k = -7 and m = -2 into the equation
q = (14)(-4)/-7
q = 8
D. 4m + 2n = 5n
4m + 2n -2n = 5n - 2n [subtraction property]
4m = 3n
4m/4 = 3n/4 [division property]
m = 3n/4 (red)
Substitute n = 8 into the equation
m = 3(8)/4
m = 6
E. w = x/y - z
w + z = x/y - z + z [addition property]
w + z = x/y
y(w + z) = x/y(y) [multiplication property]
y(w + z) = x
x = y(w + z) (light green)
Substitute w = -8, y = -5, and z = 6 into the equation
x = -5(-8 + 6)
x = -5(-2)
x = 10
F. m = 1/2(d1 + d2)
2m = d1 + d2 [multiplication property]
2m - d2 = d1 [subtraction property]
d1 = 2m - d2 (dark blue)
Substitute m = 10 and d2 = 13 into the equation
d1 = 2(10) - 13
d1 = 20 - 13
d1 = 7
G. 2r = 5s/2 - s/4
2r = (10s - s)/4
2r = 9s/4
2r(4) = 9s/4(4) [multiplication property]
8r = 9s
8r/9 = 9s/9 [division property]
8r/9 = s
s = 8r/9 (purple)
Substitute r = 9/2 into the equation
s = 8/9(9/2)
s = 4
H. vw² + y = x
vw² + y - y = x - y
vw² = x - y
vw²/v = (x - y)/v
w² = (x - y)/v
w = [tex]\sqrt{\frac{x - y}{v} }[/tex] (orange)
Substitute v = 5, x = 38, y = -7 into the equation
w = [tex]\sqrt{\frac{38 - (-7)}{5} }[/tex]
w = √9
w = 3
I. [tex]y - y_1 = m(x - x_1)[/tex]
[tex]\frac{y - y_1 }{m} = x - x_1\\\\\frac{y - y_1 }{m} + x_1 = x[/tex]
x = [tex]\frac{y - y_1 }{m} + x_1[/tex] (pink)
Substitute x1 = 9, y = 19, y1 = -5, and m = -3 into the equation
x = (19 - (-5))/-3 + 9
x = -8 + 9
x = 1
J. 2a + 3c = 17a - 21
2a - 17a = -3c - 21
-15a = -3c - 21
-15a + 21 = -3c
-15a/-3 + 21/-3 = -3c/-3
5a - 7 = c
c = 5a - 7 (brown)
Substitute a = 16/5 into the equation
c = 5(16/5) - 7
c = 16 - 7
c = 9

If x^2 + x = 1
what is (x^5 + 8)/ x+1
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).
