Log_2 8 = 3 (because 2^3 = 8), log_2 16 = 4 and log_2 32 = 5.
What are Logarithms?A base must be raised to a certain exponent or power, or logarithm, in order to produce a specific number. If bx = n, then x is the logarithm of n to the base b, which is expressed mathematically as x = logb n.
For instance, 23 = 8; hence, 3 is the base-2 logarithm of 8 or 3 = log2 8. In the same way, 2 = log10 100 since 102 = 100. The latter type of logarithms, those with base 10, are known as common or Briggsian logarithms and are denoted by the letter log n.
Logarithms, which were developed in the 17th century to expedite calculations, significantly decreased the amount of time needed to multiply integers with numerous digits.
Therefore, Log_2 8 = 3 (because 2^3 = 8), log_2 16 = 4 and log_2 32 = 5.

The lengths of the sides of a right triangle are a and b, and the hypotenuse is
c. find the area of the triangle. a=2 squareroot 3; c=4 a = sq. ft.
Answer:
Area is 2√3 ft².
Step-by-step explanation:
Given,
A right triangle having sides,
a = 2√3 ft,
c = 4 ft,
Where, c is the hypotenuse of the triangle,
If b is the other leg of the triangle,
By the pythagorean theorem,

Write the sum using summation notation, assuming the suggested pattern continues.
2 - 12 + 72 - 432 + ...
Answer:
[tex]\displaystyle \sum_{k=1}^{n}2(-6)^{k-1}[/tex]
Step-by-step explanation:
we have to write the sum using summation notation of the following series:
2-12+72-432+...
which could also be written as:
2+(-12)+72+(-432)+...
We observe that first term=2
second term=2×-6
Third term=2×-6×-6
Fourth term=2×-6×-6×-6
nth term=[tex]2\times (-6)^{n-1}[/tex]
Hence, the series sum= [tex]\displaystyle \sum_{k=1}^{n}2(-6)^{k-1}[/tex]

How to factor out the greatest common factor in a polynomial?
Final answer:
To factor out the GCF in a polynomial, identify the highest common factor, write it outside the parentheses, divide each term by the GCF, and write the quotients inside the parentheses.
Explanation:
To factor out the greatest common factor (GCF) in a polynomial, follow these steps:
First, identify the highest common factor that is present in each term of the polynomial.Write down this factor outside of a set of parentheses.Divide each term of the polynomial by the GCF, and place the resulting quotient inside the parentheses. This step can be seen as dividing both sides by the same factor to turn polynomial terms into integers, if that is easier to understand.Check your answer to see if it simplifies further and whether it is reasonable.For example, for the polynomial 6x³ + 9x², the GCF is 3x2. Factoring out the GCF gives us:
3x²(2x + 3)
The products inside the parentheses are the result of dividing the original terms by the GCF. Remember, by finding the GCF, we simplify the algebra and may check the work by expanding the factored form back out to verify it equals the original polynomial.

Which expression gives the same result as ∑4i=0(5)(1/3)i?
The symbol, ∑ is a summation sign that drills us to sum the elements of a sequence. The variable of summation is represented by an index that is placed under the summation sign and is often embodied by i. The index is always equal to 1 and adopt values beginning with the value on the right hand side of the equation and finishing it with the value over head the summation sign. So in the expression ∑4i = 0(5)(1/3)i will be the same as:
∑4i = 0(5)(1/3)i
= (1/3)⁰ + (1/3)¹ + (1/3)² + (1/3)³ + (1/3)⁴ + (1/3)⁵
= 364/243

Kite DCFE is inscribed in circle A shown below:
If the measure of arc DEF is 266°, what is the measure of ∠DEF?
Numerical Answers Expected!
Answer:
133 degrees
Step-by-step explanation:
Given is a picture of a kite DCFE inscribed in circle A
The vertices of the kite D, C, E and F lie on the circle.
A is the centre.
Arc DEF = 266 degrees
This means the subtended angle of arc DEF at the centre = Angle DAF = 266
By theorem on circles, we have central angle of any arc is twice the angle subtended by the arc on the remaining part of the circumference
Hence
Angle DEF = 1/2 angle DAF
i.e. DEF =[tex]\frac{266}{2} =133[/tex]
133 degrees
How do you solve equations for indicated variables?
ax+r=7
Solving for x?
The solution is x = (7 - r) / a.
To solve the equation ax + r = 7 for x, follow these steps:
Subtract r from both sides of the equation:
ax + r - r = 7 - r
This simplifies to:
ax = 7 - r
Divide both sides by a:
x = (7 - r) / a
Substitute the value of x back into the original equation to ensure it is correct.

The shoe store has twice as many black shoes as it does brown shoes. The total number of shoes is 66. How many brown shoes are there?
To solve the problem, denote the number of brown shoes as x, and the black shoes as 2x, as the store has twice as many black shoes. The total number of shoes is x + 2x = 66. Solving this gives us x (brown shoes) as 22.
Explanation:The subject is concerning a mathematical problem involving ratios. In the given problem, it is stated that the shoe store has twice as many black shoes as brown shoes, and the total number of shoes is 66. Here's a step-by-step process to solve it:
Let's denote the number of brown shoes as x. Therefore, due to the problem stating that there are twice as many black shoes, the number of black shoes will be 2x.The total number of shoes is the sum of the brown shoes (x) and the black shoes (2x), thus the equation becomes: x + 2x = 66.Solving this equation gives us:3x = 66.Divide both sides of the equation by 3 to isolate x, which gives us x = 22.Therefore, there are 22 brown shoes in the store.

The distance between points (3, 7) and (x1, y1) is the square root of (x1 - 3)2 + (y1 - 7)2. True or false?
Answer:
True
Step-by-step explanation:
By the distance formula,
The distance between two points [tex](a_1, b_1)[/tex] and [tex](a_2, b_2)[/tex] is,
[tex]d=\sqrt{(a_2-a_1)^2+(b_2-b_1)^2}[/tex]
Here, [tex]a_1=3[/tex], [tex]b_1=7[/tex], [tex]a_2=x_1[/tex] and [tex]b_2=y_1[/tex]
Thus, the distance would be,

The measure of an angle is 60° less than nineteen times the measure of its supplement. what is the measure of the angle?
The measure of the angle will be;
⇒ 60°
What is Supplementary angle?The sum of two or more angle is 180 degree then the angle is called the Supplementary angle.
Given that;
The statement is,
''The measure of an angle is 60° less than nineteen times the measure of its supplement.''
Let measure of an angle = x
So, The measure of its supplement = 180° - x
Hence, We can formulate;
⇒ x = (180 - x) - 60°
Solve for x as;
⇒ x = 180 - x - 60
⇒ x + x = 120
⇒ 2x = 120
⇒ x = 120/2
⇒ x = 60°
