Step-by-step explanation:
Given that
The logarithmic equation[tex]log(x.(x^2 + 3 )^{\frac{-1}{2} })[/tex]
To find
The solution of this given logarithmic equationSo, according to the question
we have,
The logarithmic equation[tex]log(x.(x^2 + 3 )^{\frac{-1}{2} })[/tex]
We know that,
∵ log(m.n) = logm + logn
Now using this property to solve that logarithmic equation
= [tex]log(x.(x^2 + 3 )^{\frac{-1}{2} })[/tex]
= [tex]logx+log(x^2 + 3 )^{\frac{-1}{2} }[/tex]
We know that,
∵ log(mⁿ) = nlogm
Now using this property to solve that logarithmic equation
= [tex]logx+log(x^2 + 3 )^{\frac{-1}{2} }[/tex]
= [tex]logx+({\frac{-1}{2} )log(x^2 + 3 )[/tex]
= [tex]logx-{\frac{1}{2} log(x^2 + 3 )[/tex]
This is the the solution of given logarithmic equation.
Logarithmic equation.
The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number. The logarithm, in its most basic form, counts the number of times the same factor appears when multiplied repeatedly; for instance, since 1000 = 10 x 10 x 10 = 103, its "logarithm base 10" is 3, or log10 (1000) = 3. When there is no possibility of confusion or when the base is irrelevant, as in big O notation, the logarithm of x to base a is written as logₐ (x), logₐ x, or even without the explicit base, log x.Answer:

Find x. Sum of angle measures: 360
Answers
Answer:

Step-by-step explanation:
→ Find the sum of the angle
x + x - 35 + x - 46 + 0.5x = 3.5x - 81
→ Equate to 360
3.5x - 81 = 360
→ Add 81 to both sides
3.5x = 441
→ Divide both sides by 3.5

Find the distance between the two numbers on a number line. Write your answer as a mixed number - 1 1/3; 12 7/12
Answers
-1 1/3 as a fraction with 12 as the denominator equals -1 4/12, because we would have to multiply all numbers by 4.
Given the two numbers -1 1/3 and 12 7/12, we can now convert into an improper fraction:
12 • 1 = 12
12 + 4 = 16
Our improper fraction conversion for -1 1/3 would be -16/12.
As for converting 12 7/12 to an improper fraction:
12 • 12 = 144
144 + 7 = 151
Our improper fraction conversion for 12 7/12 would be 151/12.
Given the two fractions -16/12 and 151/12, we can add to find the distance:
-16/12 + 151/12 = 135/12
The distance between these two numbers is 135/12, but we are not done.
Let’s convert back to a mixed number:
12 • 11 = 132
132 + 3 = 135
Therefore, our mixed number conversion would be 11 3/12. That reduces to 11 1/4. The distance between the two numbers on a number line is 11 1/4 units.

It is given that AD = AC is the midpoint of the segment DC. Therefore, DB = BC by the definition of the midpoint making the segment AB as a bisector. Additionally, ∠D is congruent to the angle ∠C by the definition of the vertical angle theorem. Triangle ΔADB is congruent to triangle ΔACB by SAS theorem.
Since angles like ∠ ABD and ∠ABC are a linear pair adding up to 180 and congruent by linear pair postulate. This means that the angle ABD and ABC each measures 90 degrees. Therefore, segment AB is perpendicular to segment DC by midpoint isosceles theorem making segment AB both as a bisector and perpendicular to the segment DC.
