use exponential form to evaluate log8(2)
Answer: [tex]\frac{1}{3}[/tex]
Explanation:
let y = [tex]log_{8} (2)[/tex]
whenever we transfer base from log from one side to other it will remain be base after shifting to the other side.
Change log to exponent form [tex]\log_xm=n\\m =x^{n}[/tex]
here we have n = y, m=2, x=8 by substituting the values
we will get
[tex]8^{y} = 2[/tex] (1)
we can write 8 in power of 2 that is [tex]2^{3}[/tex]
we will rewrite the above equation (1) as
[tex]2^{3y} = 2[/tex]
we can equate the power when base is same then we will get
3y = 1
then
[tex]y=\frac{1}{3}[/tex]
The result of the logarithmic expression [tex]log _82=x[/tex] is 1/3
Let the given logarithmic function be x to have:
[tex]log _82=x[/tex]
This can be transformed into indices to have:
[tex]8^x = 2[/tex]
Solve the resulting indices for "x" a shown:
[tex](2^3)^x = 2^1\\2^{3x}=2^1[/tex]
Cancel the base and equate the power to have:
[tex]3x = 1\\x = \frac{1}{3}[/tex]
Hence the result of the logarithmic expression [tex]log _82=x[/tex] is 1/3

What are triangles?A polygon with three sides, angles, and vertices is called a triangle.
Given that, triangle side lengths, we need to identify the triangle as acute, right or obtuse,
How to solve the triangle?
It will be a right triangle if a² + b² = c², It will be аcute if a² + b² > c² and it'll be obtuse if a² + b² < c².
1) a² + b² = 3² + 4² = 9 + 16 = 25 and c² = 5² = 25
25 = 25
This is a right triangle.
2) a² + b² = 5² + 6²
= 25 + 36 = 61
c² = 7² = 49
61 > 49 = аcute triangle.
3) a² + b² = 8² + 9²
= 64 + 81 = 145
c² = 12² = 144
145 > 144 = аcute triangle.

The sum of two numbers is 67 . the smaller number is 9 less than the larger number. what are the numbers? larger number: smaller number:
To solve the problem, two equations were set up based on the conditions given. After substitution and simple algebraic operations, the larger number was found to be 38 and the smaller number to be 29.
The question involves finding two numbers where the sum is 67, and the smaller number is 9 less than the larger number.
Let's define the larger number as x and the smaller number as y. According to the problem:
x + y = 67 (Equation 1)y = x - 9 (Equation 2)Substitute Equation 2 into Equation 1:
x + (x - 9) = 67
2x - 9 = 67
2x = 67 + 9
2x = 76
x = 38
Now, we can find y using Equation 2:
y = x - 9
y = 38 - 9
y = 29
Therefore, the larger number is 38 and the smaller number is 29.
The party planning committee has to determine the number of tables needed for an upcoming event. If a square table can fit 8 people and a round table can fit 6 people, the equation 150 = 8x + 6y represents the number of each type of table needed for 150 people. The variable x represents the number of . The variable y represents the number of . If y = 9, find the value of x. The committee needs square tables.
Answer:
The variable "x" is the number of square tables and the variable "y" represents the number of round tables.
The committee needs 12 square tables.
Step-by-step explanation:
You know that the equation is 150 = 8*x + 6*y. You also know that 8 people can fit on a square table and 6 people can fit on a round table. Then 8 people multiplied by the amount of square tables plus 6 people by the amount of round tables should add 150 people. So in the previous equation the variable "x" is the number of square tables and the variable "y" represents the number of round tables.
If the number "y" of round tables is 9, you can replace this value in equation 150 = 8*x + 6*y, with 150 = 8*x + 6*9. Solving this last equation, you can calculate the value of the variable "x", that is, calculate the amount of square tables needed.
150= 8*x + 6*9
150= 8*x + 54
150-54= 8*X +54 - 54
96 = 8*x
[tex]\frac{96}{8} =\frac{8}{8} *x[/tex]
12=x
So, the committee needs 12 square tables.
The number of square tables that's needed will be 12 square tables.
The equation given is 150 = 8x + 6y and this represents the number of each type of table that's needed for 150 people.
Since 6 people are already give for the round tables, then to solve the square tables will be:
150 = 8x + 6y
150 = 8x + (6 × 9)
150 = 8x + 54
Collect like terms
8x = 150 - 54
8x = 96
Divide both side by 8
8x/8 = 96/8.
x = 12
Therefore, the number of square table that's needed will be 12 square tables.

Joanna has a flat wooden triangular piece as part of a wind chime. the piece is suspended by a wire anchored at a point equidistant from the sides of the triangle. where is the anchor point located?
Final answer:
Joanna's wind chime is suspended from the centroid of the triangular piece, which is the intersection point of the triangle's three medians and serves as its center of gravity.
Explanation:
The anchor point where Joanna has suspended the flat wooden triangular piece of the wind chime is known as the centroid of the triangle. The centroid is the point where the three medians of the triangle intersect, and it is always located inside the triangle. A median of a triangle is a line segment connecting a vertex to the midpoint of the opposing side. The centroid is also the triangle's center of gravity, meaning it is the balance point where the triangle can be suspended and remain in equilibrium. For any given triangle, the centroid will be found at a point that is one-third of the distance from each vertex to the midpoint of the opposite side.

A square piece of tile with sides 12 inches is cut along a diagonal, What is the length of the diagonal rounded to the nearest inch?
To find the length of the diagonal of a square tile, you can use the Pythagorean theorem. Given that the side length of the tile is 12 inches, the length of the diagonal is approximately 17 inches when rounded to the nearest inch.
Explanation:To find the length of the diagonal of a square tile, you can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, the two sides of the right triangle are the sides of the square tile, and the hypotenuse is the diagonal. Given that the side length of the tile is 12 inches, we can calculate the length of the diagonal as follows:
Square the length of one side: 12 x 12 = 144
Multiply the result by 2: 144 x 2 = 288
Take the square root of the result: √288 ≈ 16.97 inches
Rounded to the nearest inch, the length of the diagonal of the square tile is 17 inches.
Final answer:
The length of the diagonal of the square, rounded to the nearest inch, is 17 inches.
Explanation:
The length of the diagonal of a square can be found using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In this case, the two sides of the square are both 12 inches long. So, we have:
hypotenuse² = side1² + side2²
hypotenuse² = 12² + 12²
hypotenuse² = 144 + 144
hypotenuse² = 288
To find the length of the hypotenuse (or the diagonal), we take the square root of both sides:
hypotenuse = √(288)
hypotenuse = 16.97 inches (rounded to the nearest inch)

Given: Triangles ABC and DBC are isosceles, m∠BDC = 30°, and m∠ABD = 155°.
Find m∠ABC, m∠BAC, and m∠DBC.
Answer:
- m∠ABC = m∠ACB = 25° (as triangle ABC is isosceles).
- m∠BAC = 130°.
- m∠BDC = m∠DCB = 30° (as triangle DBC is isosceles).
Explanation:
We can solve this problem by using the properties of isosceles triangles and the fact that the sum of angles in a triangle is 180 degrees.
1. Since triangle DBC is isosceles, m∠DBC = m∠DCB.
Therefore, m∠DCB = 30°.
2. In triangle ABC, since it's isosceles, m∠ABC = m∠ACB.
3. We know that m∠ABD = 155°. Since triangle ABD is a triangle, the sum of its angles is 180 degrees. So, m∠ABD + m∠BAD + m∠ADB = 180°. Therefore, m∠BAD + m∠ADB = 180° - 155° = 25°.
4. Since triangle ABC is isosceles, m∠ABC = m∠ACB = 25°.
5. In triangle ABC, the sum of its angles is 180 degrees. So, m∠ABC + m∠BAC + m∠ACB = 180°. Substituting the known values, we get 25° + m∠BAC + 25° = 180°. Solving for m∠BAC,
we find m∠BAC = 180° - 25° - 25° = 130°.
