Answer: [tex]x=11[/tex]
Step-by-step explanation:
Remembert that, by definition:
[tex]log_b(x)=y[/tex] → [tex]b^y=x[/tex]
Then, you can rewrite [tex]log_4(2x-6)=2[/tex] in exponential form:
[tex]4^2=2x-6[/tex]
Now you can solve for the variable "x":
Add 6 to both sides of the equation:
[tex]4^2+6=2x-6+6[/tex]
[tex]22=2x[/tex]
And finally you must divide both sides of the equation by 2, then:
[tex]\frac{22}{2}=\frac{2x}{2}\\\\x=11[/tex]
Name a container that you see at home that when filled has a liquid volume of about 1 liter.
Answer: flower vase
Step-by-step explanation:
A container that has a liquid volume of about 1 liter at home is typically a soda bottle. A liter is a metric unit of capacity and is equivalent to 1,000 cubic centimeters or milliliters, making it a convenient measure for everyday use.
An example of a container that you might find at home which, when filled, has a liquid volume of about 1 liter is a soda bottle. Liters and milliliters are metric units for measuring capacity. A liter is a convenient measure for everyday liquid volumes and is commonly used for beverages and other liquids in the home. Since a liter is equal to 1,000 milliliters, and taking into account that a juice box holds about 25 centiliters, which is 250 milliliters, a soda bottle's capacity is approximately four times that of a typical juice box. It's interesting to note that the liter can also be connected to cubic meters, as 1 liter is the same as 1,000 cubic centimeters (1,000 cm³), making these units interchangeable.

Answer:
[tex]b = 17[/tex]
Step-by-step explanation:
For this triangle we have to
[tex]a=18.2\\B=62\°\\C=48\°[/tex]
We want to find the length of b
We know that the sum of the internal angles of a triangle is 180 °
So
[tex]A + 62 +48=180\\\\A=180-62-48\\\\A=70\°[/tex]
Now we use the sine theorem to find the length of b:
[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}[/tex]
Then:
[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}\\\\b=\frac{sin(B)}{\frac{sin(A)}{a}}\\\\b=a*\frac{sin(B)}{sin(A)}\\\\b=(18.2)\frac{sin(62)}{sin(70)}\\\\b=17[/tex]
What is the equation of a line that passes through the point (2, 4) and has a y-intercept at y = -10?
Answer:
The equation of the line is y = 7x - 10
Step-by-step explanation:
* Lets revise the form of the equation
- The form of the equation of a line is y = mx + c , where m is the slope
of the line and c is the y-intercept
- The y-intercept means the line intersect the y-axis at point (0 , c)
- The slope of the line which passes through points (x1 , y1) , (x2 , y2)
is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
* Lets solve the problem
∵ The y-intercept is y = -10
∴ The line intersects the y-axis at point (0 , -10)
∵ The line passes through the points (2 , 4) and (0 , -10)
- Lets find the slope of the line using the rule of the slope above
∵ [tex]m=\frac{-10-4}{0-2}=\frac{-14}{-2}=7[/tex]
∴ The slope of the line is 7
∵ c is the y-intercept
∵ The y-intercept is y = -10
∴ c = -10
∵ y = mx + c
∴ y = 7x + -10
∴ y = 7x - 10
* The equation of the line is y = 7x - 10

If you were to line up all the numbers in chronological order, the order would be: 5, 8, 8, 10, 10, 10, 11, 12, 12, 14, 17, 17, 19, 20, 20, 21. Twelve is the center of all the numbers. There's eight numbers on each side of 12. Hope this helps! Please mark brainliest! Thank you v much! :)
Answer:
C) 12
Step-by-step explanation:
Step 1: List the numbers in order from least to greatest. Take a look at the data and cross out numbers as you place them. There are 16 numbers. The order of these numbers are:
5, 8, 8, 10, 10, 10, 11, 12, 12, 14, 17, 17, 19, 20, 20, 21
Step 2: Cross out numbers from each side to the furthest left and right. By the time you do this, the remaining numbers should be 12 and 12.
Step 3: Find the median. Because there are two numbers left, you do this by adding the two remaining numbers and divinding them by 2. However, because they are the same number, you can safely say that the median is 12.
A right triangle △ABC with right angle C is inscribed in a circle. Find the radius of this circle if:
b
Given m∠C = 90°, k(O, r) inscribed in △ABC, AC = 18 cm, m∠B = 30°. Find r.
Answer:
The radius = 18 cm
Step-by-step explanation:
* Lets take about the inscribed triangle in a circle
- If the three vertices of a triangle lie on the circumference of a circle,
then this triangle is inscribed in the circle
- The vertices of the triangle are inscribed angles in the circle
- The inscribed angle opposite to a circle's diameter is always a
right angle (its measure is 90°)
- Now lets solve the problem
∵ Δ ABC is a right triangle at C
∴ m∠C = 90°
∵ Δ ABC is inscribed in a circle
∴ A , B , C lie on the circumference of the circle
∴ ∠A , ∠B , ∠C are inscribed angles in the circle
∴ m∠C = 90°
∵ ∠C is opposite to the side AB
∴ AB is the diameter of the circle ⇒ from the bold note above
∵ m∠B = 30°
∵ AC = 18 cm
- Lets use the trigonometry function to find the length of AB
* In Δ ABC
∵ AC is opposite to angle B
∵ AB is the hypotenuse
∵ sin Ф = opposite/hypotenuse
∴ sin B = AC/AB
∴ sin (30)° = 18/AB ⇒ using cross multiplication
∴ AB sin (30)° = 18 ⇒ divide both sides by sin (30)°
∴ AB = 18/sin(30)°
∵ sin(30)° = 1/2
∴ AB = 18/(1/2) = 36 cm
∵ AB is the diameter of the circle
∵ The length of the radius of a circle = 1/2 the length of the diameter
∴ The radius = 1/2 × 36 = 18 cm

when an exponent of a power is an even number and the base is a negative number, the value is always:
A. positive
B. negative
C. 0
D. none of the choices
Answer:
The correct answer option is A. positive.
Step-by-step explanation:
When an exponent or a power is an even number and the base is a negative number, the value is always positive.
Suppose we have a negative base [tex] - 3 [/tex] and a power which is even, lets say, [tex] 6 [/tex] so what we get is a positive value.
[tex](-3)^6=729[/tex]
Therefore, a negative base with even power is always a positive value.
Answer: A. positive
Step-by-step explanation:
We know that powers are written in this form:
[tex]b^m[/tex]
Where "b" is the base and "m" is the exponent.
By definition, the exponent indicates how many times to base must be multiplied by itself. Then, if the base is negative and the exponent is an even number, you get:
[tex](-3)^4=(-3)(-3)(-3)(-3)=81\\\\\\(-2)^2=(-2)(-2)=2\\\\\\(-5)^6=(-5)(-5)(-5)(-5)(-5)(-5)=15,625[/tex]
Therefore, when an exponent of a power is an even number and the base is a negative number, the value is always positive.
The table below shows two equations:

Equation 2 |2x + 3| + 8 = 3
Which statement is true about the solution to the two equations?
* Equation 1 and equation 2 have no solutions.
* Equation 1 has no solution, and equation 2 has solutions x = −4, 1.
* The solutions to equation 1 are x = 3, −1.5, and equation 2 has no solution. *
* The solutions to equation 1 are x = 3, −1.5, and equation 2 has solutions x = −4, 1.
Answer:
Option C is correct.
Step-by-step explanation:
Equation 1 |4x − 3|− 5 = 4
Adding +5 on both sides
|4x − 3|− 5 +5 = 4 +5
|4x − 3| = 9
Apply absolute rule:
IuI = a and a>0 then u = a and u = -a
so, 4x-3 = 9 and 4x-3 = -9
Solving
4x = 9+3 and 4x = -9+3
4x = 12 and 4x = -6
x = 12/4 and x = -6/4
x = 3 and x = -3/2 or -1.5
Equation 2 |2x + 3| + 8 = 3
Adding -8 on both sides
|2x + 3| + 8 -8 = 3 -8
|2x + 3| = -5
Apply absolute rule:
IuI = a and a>0 then u = a and u = -a
But we cannot apply absolute rule because in our case a < 0 i.e -5
So, Equation 2 has no solutions.
Hence Option C The solutions to equation 1 are x = 3, −1.5, and equation 2 has no solution is correct.
Which number line shows the solutions to n < -3?

The number line for the inequality n < -3 would have an open circle at -3 and be shaded to the left, representing all numbers less than -3.
When considering the inequality n < -3, the number line that represents the solutions to this inequality would show all the numbers that are less than -3. This means that any point to the left of -3 on the number line would be shaded to indicate that it is part of the solution set. Additionally, the number -3 would typically be represented with an open circle, indicating that -3 is not included in the set of solutions because the inequality is strictly less than, not less than or equal to.
If you were to graph this inequality on a number line, you would start at the point -3 and shade everything to the left of -3 going towards negative infinity. This visualization shows that n can take any value that is less than -3. Therefore, the number line for the solutions of n < -3 would look like a horizontal line with an open circle at -3 and a shaded region extending to the left from -3.

26 inches : right rectangular prism, 10x 3 x 14 inches
48 inches : cube with 12-inches edges
34 inches : rectangular prism, 5x12x4 diagonal of 13 inches
Step-by-step explanation:
right rectangular prism, 10x 3 x 14 inches
The cross-section is parallel to the base, so it cuts the height, maintaining the length and width. So, we have:
P = 10 + 3 + 10 + 3 = 26 inches
cube with 12-inches edges
This time, the cross-section is done perpendicular to the base, but in this case it doesn't matter since it's a cube... so it could be done in any direction and it wouldn't change the result.
P = 12 + 12+ 12 + 12 = 48 inches
rectangular prism, 5x12x4 diagonal of 13 inches
The cut is done perpendicular to the base, but along a diagonal of 13 inches, so the height is preserved, and the diagonal length becomes the new side other than height.
P = 13 + 4 + 13 + 4 = 34 inches
cross-section, cube, 16 inches
Again, the cross-section is done parallel to the base, but in this case it doesn't matter since it's a cube... so it could be done in any direction and it wouldn't change the result.

Find an equation of the line L that passes through the point (2,-12) and satisfies the given condition.
L is perpendicular to the line 8x + 2y = -8.
Answer:
y = 1/4 x - 12.5
Step-by-step explanation:
8x + 2y = -8 (rewrite in y = mx + b form)
2y = -8x -8 (divide both sides by 2)
y = -4x -2 for first line
Perpendicular line L has "opposite/inverse" slope
y = -4x + b becomes y = 1/4 x + b
What's b (the y-intercept)?
Plug the point (2, -12) into the equation y = 1/4 x + b to solve for b
-12 = 1/4 (2) + b
-12 = 1/2 + b (subtract 1/2 from both sides)
-12.5 =b (rewrite equation)
y = 1/4 x - 12.5

Answer:
[tex]P (t) = 580e ^ {0.18t}[/tex] or [tex]P (t) = 580 (1.18) ^ t[/tex]
Step-by-step explanation:
There are two models of exponential growth that you can use to predict the population of bacteria after t hours.
I) [tex]P (t) = pe ^ {rt}[/tex]
II) [tex]P (t) = p (1 + r) ^ t[/tex]
Where
p is the initial population of bacteria
r is the growth rate
t is the time in hours.
In this case we know that:
[tex]p = 580\\\\r = \frac{18}{100}\\\\r = 0.18[/tex]
Then the equations that can be used to predict the population of bacteria after t hours are:
I) [tex]P (t) = 580e ^ {0.18t}[/tex]
II)[tex]P (t) = 580 (1 + 0.18) ^ t[/tex]

Here [tex]a_1=\frac{2}{9}[/tex] and common ratio [tex](r) = \frac{\frac{2}{3} }{\frac{2}{9} } =3[/tex].
The formula we will use to find the 10th term is:
nth term = [tex]a_1 \times r^{(n-1)}[/tex]
Substituting the values in the formula to get:
10th term = [tex]\frac{2}{9} \times 3^{(10-1)}[/tex]
10th term = 4374
