The recent earthquake in turkey was measured to be a magnitude 8. How much stronger was this earthquake compared to a magnitude 5
Earthquake in Turkey was 1000 times much stronger, compared to a magnitude 5 earthquake
What is Richter scale?The Richter scale (also known as the Richter magnitude scale) assigns magnitude numbers to quantify the energy released by an earthquake. Developed by Charles Richter in the 1930s, the Richter scale is a base 10 logarithmic scale that defines magnitude as the logarithm of the ratio of seismic wave amplitudes to smaller amplitudes.
As measured by seismographs, an earthquake measuring 5.0 on the Richter scale has 10 times more shaking amplitude than a 4.0 earthquake.
Given,
Magnitude 6 is 10² = 100 times greater than magnitude 4.
Magnitude 4 is 10 times greater than magnitude 4.
By the above data, 1 digit greater magnitude means 10 times powerful.
Earthquake on turkey is of 8 magnitude
∵ Difference of 8 magnitude and 5 magnitude = 8 - 5 = 3
∴ 8 magnitude earthquake is 1000 times greater.
Hence, 1000 times much stronger was earthquake in Turkey, compared to a magnitude 5 earthquake.

Collect like terms
13r + 181 = 90
Subract 181 from both sides
13r = 90-181
13r = - 91
r = - 7
Now insert the value of r into BFG (5r +68)
5r + 68 = 5(-7) +68
= -35 + 68
=33
Check your answer by inserting the value of r into 8r +113
8r + 113 =8(-7) +113
-56+113= 57

After one hour 0.75 mg of medicine remains in the bloodstream. Find an equation that defines f.
The equation that defines "f" for the amount of medicine in the blood stream is f(x) = 0.75ˣ * f(0).
Exponential decay: what is it?The mathematical function known as exponential decay can be used to illustrate a quantity's progressive decline over time. The quantity that is lost or decays in each unit of time is proportionate to the amount that is still present, which is defined by a constant relative rate of change. Exponential decay is frequently seen in physical, chemical, and biological systems, where it explains the ageing of a population or the deterioration of radioactive isotopes, soil minerals, drugs, or nutrients over time.
The following equation to model the situation:
[tex]f(t) = f(0) * e^{(-kt)}[/tex]
where, f(0) is the initial amount of medicine
[tex]f(t) = f(0) * e^{(-k*1)} = 0.75\\\\f(0) * e^{-k} = 0.75\\\\[/tex]
Taking ln on both sides:
-k = ln(0.75 / f(0))
k = -ln(0.75 / f(0))
Substituting this value of "k" back into the equation for "f(x)", we get:
f(t) = f(0) * (0.75 / f(0))ˣ
Simplifying this equation further, we get:
f(t) = 0.75ˣ * f(0)
Therefore, the equation that defines "f" is f(x) = 0.75ˣ * f(0).

The complete question is:
A cistern is to be built of cement. The walls and bottom will be 1ft. thick. The outer height will be 20 ft. The inner diameter will be 10 ft. To the nearest cubic foot, how much cement will be needed for the job?
The amount of cement needed is 609 cubic ft.
The amount of cement needed for the job can be calculated by finding the difference between the volume of the outer cistern and the volume of the inner cistern.
The volume of the outer cistern can be found using the formula for the volume of a cylinder, V = πr²h, where r is the radius and h is the height. The outer radius is half the outer diameter, or 10ft/2 = 5ft. The outer height is 20ft. So the volume of the outer cistern is:
V = π(5ft)²(20ft) = 1570.8 cubic ft
The volume of the inner cistern can be found using the same formula, but with the inner radius and inner height. The inner radius is the outer radius minus the thickness of the walls, or 5ft - 1ft = 4ft. The inner height is the outer height minus the thickness of the bottom, or 20ft - 1ft = 19ft. So the volume of the inner cistern is:
V = π(4ft)²(19ft) = 961.6 cubic ft
The difference between the two volumes is the amount of cement needed:
1570.8 cubic ft - 961.6 cubic ft = 609.2 cubic ft
To the nearest cubic foot, the amount of cement needed is 609 cubic ft.

"The retail revenue from shopping on the Internet was projected to grow
at a rate of 56% per year. is this wxponitial growth"
Yes, this is exponential growth. Exponential growth occurs when the rate of increase is proportional to the current amount. In this case, the retail revenue from shopping on the Internet is projected to grow at a rate of 56% per year, meaning that the amount of growth each year is 56% of the current amount. This is an example of exponential growth because the rate of growth is proportional to the current amount.
To further illustrate this point, let's say that the retail revenue from shopping on the Internet in year 1 is $100. In year 2, it would grow by 56% to $156 ($100 + ($100 * 0.56)). In year 3, it would grow by 56% again to $243.36 ($156 + ($156 * 0.56)). As you can see, the amount of growth each year is proportional to the current amount, which is the definition of exponential growth.

By answering the above question, we may infer that Ling will thus require equation 42 feet of wallpaper border to install at the top of the three walls.
What is equation?A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The logo and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.
Three walls, each 14 feet long and 12 feet tall, are being wallpapered by Ling. Just the top of the wall will be covered by the border. As a result, each wall requires a 14-foot-long wallpaper border.
The length of the border on each of the three walls must be added together to determine the overall length of wallpaper border required. So:
Whole wallpaper border length is one wall's border length times the number of walls.
Overall wallpaper border length is 14 feet multiplied by 3 walls.
42 feet is the total length of the wallpaper border.
Ling will thus require 42 feet of wallpaper border to install at the top of the three walls.

Exercise 6.2: \( 3+3 \) points. Let \( A=\left[\begin{array}{ccc}1 & 0 & 0 \\ 0 & 1 & 1 \\ 0 & -1 & 1\end{array}\right] \). (a) Is \( A \) diagonalizable as an element of \( M_{3 \times 3}(\mathbb{R})
The matrix \( A \) is not diagonalizable as an element of \( M_{3 \times 3}(\mathbb{R}) \), because there does not exist a basis of \( \mathbb{R}^{3} \) consisting of eigenvectors of \( A \).
The matrix \(A=\left[\begin{array}{ccc}1 & 0 & 0 \\ 0 & 1 & 1 \\ 0 & -1 & 1\end{array}\right] \) is diagonalizable as an element of \( M_{3 \times 3}(\mathbb{R}) \) if and only if there exists a basis of \( \mathbb{R}^{3} \) consisting of eigenvectors of \( A \).
To determine if \( A \) is diagonalizable, we need to find the eigenvalues and eigenvectors of \( A \).
The characteristic polynomial of \( A \) is given by:
\(\det(A-\lambda I)=\left|\begin{array}{ccc}1-\lambda & 0 & 0 \\ 0 & 1-\lambda & 1 \\ 0 & -1 & 1-\lambda\end{array}\right|=(1-\lambda)^{3} \)
The eigenvalues of \( A \) are the roots of the characteristic polynomial, which are \( \lambda=1 \) with multiplicity 3.
To find the eigenvectors of \( A \), we need to solve the equation \( (A-\lambda I)x=0 \) for each eigenvalue.
For \( \lambda=1 \), we have:
\( (A-1I)x=0 \)
\(\left[\begin{array}{ccc}0 & 0 & 0 \\ 0 & 0 & 1 \\ 0 & -1 & 0\end{array}\right]x=0 \)
The solution to this equation is the eigenspace of \( \lambda=1 \), which is spanned by the eigenvector \( x=\left[\begin{array}{c}1 \\ 0 \\ 0\end{array}\right] \).
Since the eigenspace of \( \lambda=1 \) has dimension 1, there is only one linearly independent eigenvector for this eigenvalue. Therefore, the matrix \( A \) is not diagonalizable as an element of \( M_{3 \times 3}(\mathbb{R}) \), because there does not exist a basis of \( \mathbb{R}^{3} \) consisting of eigenvectors of \( A \).

The z-scores for 17, 33, and 53 are -0.82, 0.22, and 1.52, respectively.
To find the z-scores for 17, 33, and 53, we first need to calculate the mean and standard deviation of the data set.
Mean = (10 + 13 + 17 + 19 + 22 + 23 + 29 + 33 + 34 + 35 + 35 + 38 + 53 + 68)/14 = 29.57
Standard deviation = √[(10-29.57)² + (13-29.57)² + (17-29.57)² + (19-29.57)² + (22-29.57)² + (23-29.57)² + (29-29.57)² + (33-29.57)² + (34-29.57)² + (35-29.57)² + (35-29.57)² + (38-29.57)² + (53-29.57)² + (68-29.57)²]/13 = 15.37
Now we can calculate the z-scores using the formula:
z-score = (data point - mean)/standard deviation
Z-score for 17 = (17-29.57)/15.37 = -0.82
Z-score for 33 = (33-29.57)/15.37 = 0.22

The two real solutions of the equation are:
z=32.5/18 ± √(81+32.5z)/18
The equation 18z2-65z-72=0 can be solved by completing the square. We start by taking half of the coefficient of the squared term and squaring it:
(18/2)2 = (9)2 = 81
We then add 81 to both sides of the equation to complete the square:
18z2-65z-72+81=0+81
18z2-65z+9=81
Now, we take half of the coefficient of the z-term, subtract it from both sides of the equation, and add it in the parentheses:
18z2-(65/2)z+(65/2)z+9=81+(65/2)z
(18z-32.5)2=81+32.5z
We now have a perfect square on the left side, so we can simplify:
(18z-32.5)2=81+32.5z
18z-32.5=±√(81+32.5z)

For the inequality y ≤ -2/3x + 6 the graph is plotted with the points (0, 6) and (9, 0).
What is an inequality?
In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.
The inequality y ≤ -2/3x + 6 is already in slope-intercept form (y = mx + b), where the slope is -2/3 and the y-intercept is 6.
To find some possible solutions for this inequality, we can choose any value of x and then solve for y.
Let's choose x = 0 -
y ≤ -2/3(0) + 6
y ≤ 6
So when x = 0, any y value less than or equal to 6 will satisfy the inequality.
This gives us the solution set -
{(x, y) | y ≤ 6}
Now choose a value of y to find another point that satisfies the inequality. Let's choose y = 0 -
0 ≤ -2/3x + 6
2/3x ≤ 6
x ≤ (6 × 2)/3
x ≤ 9
So when y = 0, any x value less than or equal to 0 will satisfy the inequality.

To subtract these rational expressions, we need to find a common denominator. The least common denominator (LCD) of 4d and 6d is 12d. We can then rewrite the expressions with the LCD as the denominator:
(3)/(4d) = (3 * 3)/(4d * 3) = (9)/(12d)
(1)/(6d) = (1 * 2)/(6d * 2) = (2)/(12d)
Now we can subtract the numerators and keep the same denominator:
(9)/(12d) - (2)/(12d) = (9 - 2)/(12d) = (7)/(12d)
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor (GCF), which is 1:

***Please show steps.
The domain of the function y = log(6 + 5x) is (-6/5, ∞).
To find the domain of the given function, y = log(6 + 5x), we need to determine the values of x for which the function is defined.
Step 1: The logarithmic function is only defined for positive values of the argument. So, we need to set the argument of the logarithm greater than zero:
6 + 5x > 0
Step 2: Solve for x:
5x > -6
x > -6/5
Step 3: The domain of the function is the set of all x values that satisfy the inequality. So, the domain is:
{x | x > -6/5}
In interval notation, the domain can be written as:

→ the area of the triangle = 26 : 2 = 13 square units
Answer:
Step-by-step explanation:
you would copy and paste another triangle on top to form a rectangle. That would make the rectangle's length 13 units and its width 2 units. the area of a rectangle is found by A=length x width which in this case is 26 units^2. A single triangle's area is 1/2 the area of the rectangle making it 26/2 which is 13.
So the area of the triangle is 13 units^2.

Which of the pair of functions are not inverseTo determine if two functions, g(x) and h(x), are inverses of each other, we need to check if the composition of the two functions, g(h(x)) and h(g(x)), both result in x.
A. g(x) = 2 + 9 = 11, h(x) = 1/2x - 9
g(h(x)) = g(1/2x - 9) = 2 + 9 = 11
h(g(x)) = h(11) = 1/2(11) - 9 = -3/2
Since g(h(x)) ≠ x and h(g(x)) ≠ x, the functions g(x) and h(x) are not inverses of each other.
B. g(x) = x - 1, h(x) = x + 1
g(h(x)) = g(x + 1) = (x + 1) - 1 = x
h(g(x)) = h(x - 1) = (x - 1) + 1 = x
Since g(h(x)) = x and h(g(x)) = x, the functions g(x) and h(x) are inverses of each other.
C. g(x) = 3x - 6, h(x) = 1/3x + 2
g(h(x)) = g(1/3x + 2) = 3(1/3x + 2) - 6 = x
h(g(x)) = h(3x - 6) = 1/3(3x - 6) + 2 = x
Since g(h(x)) = x and h(g(x)) = x, the functions g(x) and h(x) are inverses of each other.
D. g(x) = 3x + 4, h(x) = x - 4/3
g(h(x)) = g(x - 4/3) = 3(x - 4/3) + 4 = 3x - 4
h(g(x)) = h(3x + 4) = (3x + 4) - 4/3 = 3x + 8/3
Since g(h(x)) ≠ x and h(g(x)) ≠ x, the functions g(x) and h(x) are not inverses of each other.

The difference in a sustraction is equal to the remainder of the minute less the sustrancing.
The remainder between the new minuendo and the sustraendo will be greater than the previous remainder if the minuendo increases by just 10 units.
For instance, the difference is 15 if the remainder is
=> 25 – 10.
If we only increase the minimum by 10 units,
we will have

1. A person should choose one family pizza.
2. The area of two medium pizza < area of 1 large pizza.
3. The area of two medium pizza is 1413.8 square cm and the area of one large pizza is 1661.9 square cm.
What is area?
An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.
I would one family pizza.
I would choose one family because the total area of two medium pizzas is less than the area of a family pizza.
This means that the two medium pizzas will have less pizza to share between the same number of people, so everyone will get a smaller slice of pizza.
To calculate the areas of the pizzas, we need to use the formula for the area of a circle -
Area of a circle = π × (radius)²
For the family pizza with a diameter of 46 cm, the radius is 23 cm. Therefore, the area of the family pizza is -
Area of family pizza = π × (23 cm)² ≈ 1661.9 square cm
For two medium pizzas with a diameter of 30 cm, the radius is 15 cm. Therefore, the area of each medium pizza is -
Area of each medium pizza = π × (15 cm)² ≈ 706.9 square cm
The total area of two medium pizzas is -
Total area of two medium pizzas = 2 × (Area of each medium pizza) ≈ 1413.8 square cm
Since the total area of two medium pizzas is less than the area of the family pizza, it means that two medium pizzas have less pizza to share between the same number of people.
Therefore, choosing one family pizza would be a better option.

Add the proper constant to the binomial so that the resulting trinomial is perfect square. Then factor the trinomial y2 _ 18y Add the proper constant to make a perfect square trinomial: y2 _ 18y (Type an integer or a simplified fraction )
To make the trinomial y2 - 18y a perfect square, we need to add a constant that is equal to (18/2)^2 = 81.
This is because a perfect square trinomial is in the form (x + a)^2 = x^2 + 2ax + a^2. In this case, x = y and 2a = -18, so a = -9 and a^2 = 81. So, the trinomial becomes y2 - 18y + 81, which is a perfect square.
To factor the trinomial, we can use the formula (x + a)^2 = x^2 + 2ax + a^2, where x = y and a = -9. So, the trinomial y2 - 18y + 81 can be factored as (y - 9)^2.
Therefore, the proper constant to add to the binomial y2 - 18y to make it a perfect square trinomial is 81, and the factored form of the trinomial is (y - 9)^2.

A glass fish tank is in the shape of a rectangular box with length 1.1 m, width 8 m, height 7 dm a Calculate the area of glass for the tank without lid B how many liters of water need to be filled to calculate the volume of water occupying 70 % volume of a tank 1 decimeter cubic meter is equal to 11 water *Help me please*this is 5th grade math
4312 liters of water need to be filled to calculate the volume of water occupying 70% volume of the tank.
What is volume ?
Volume is the amount of space occupied by an object or a substance. It is a measure of the amount of three-dimensional space an object or a substance occupies. The volume of an object or substance is typically measured in cubic units, such as cubic meters (m³), cubic centimeters (cm³), or cubic feet (ft³).
A) To calculate the area of glass for the tank without lid, we need to find the total surface area of the rectangular box.
The front and back sides have dimensions 1.1 m x 7 dm = 1.1 m x 0.7 m = 0.77 m² each.
The top and bottom sides have dimensions 1.1 m x 8 m = 8.8 m² each.
The left and right sides have dimensions 7 dm x 8 m = 0.7 m x 8 m = 5.6 m² each.
Therefore, the total surface area of glass for the tank without lid is:
0.77 m² + 0.77 m² + 8.8 m² + 8.8 m² + 5.6 m² + 5.6 m² = 30.6 m²
B) To calculate the volume of water occupying 70% of the tank, we first need to calculate the volume of the tank.
The volume of a rectangular box is found by multiplying its length, width, and height:
Volume = length x width x height
We have:
length = 1.1 m
width = 8 m
height = 7 dm = 0.7 m
Volume = 1.1 m x 8 m x 0.7 m = 6.16 m³
Next, we need to find 70% of the volume of the tank:
70% of 6.16 m³ = 0.7 x 6.16 m³ = 4.312 m³
Finally, we need to convert cubic meters to liters, using the conversion factor given:
1 m³ = 1000 L
Therefore,
4.312 m³ x 1000 L/m³ = 4312 L
Therefore, 4312 liters of water need to be filled to calculate the volume of water occupying 70% volume of the tank.

A physics class has 40 students. Of these, 10 students are physics majors and 14 students are female. Of the physics majors, three are female. Find the probability that a randomly selected student is female or a physics major.
The probability that a randomly selected student is female or a physics major would be 0.65.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring needs to be 1.
The probability that a randomly selected student is female or a physics major can be calculated:
P(PM or F) = P(PM) + P(F) - P(PMF)
Where P(PM or F) = Probability of student selected is Physics Major or Female needed to find.
P(PM) = Probability of student selected is Physics Major
P(PM) = Number of Physics Major / Total number of students in the Physics class
P(PM) = 14 / 40 = 0.35
P(F) = Probability of student selected is Female = Number of female students in the Physics class / Total number students in the Physics class = 18 / 40 = 0.45
P(PMF) = Probability of student selected is Physics Major and Female = 6 / 40 = 0.15
Substituting the values into equation (1);
P(PM or F) = 0.35 + 0.45 - 0.15

Based on the information in the table, we can infer that the number that correctly replaces A is 880.
How to find the number that replaces A?To find the number that replaces A we must analyze the information in the table. In this case we must find the difference between the distances to the destination in 1, 2, 3, 5 hours.
In this case we can subtract the distance of hour 1 from that of hour 2 to identify the difference.
1,060 - 1,000 = 60So, the difference would be 60. To check it we can test with the difference between hour 2 and 3
1,000 - 940 = 60So we can infer that the distance difference between each hour is 60 miles. Therefore, the value of A would be the value of the distance after 3 hours (940) minus 60.
940 - 60 = 880So the correct option would be option B, 880.
