A formula for calculating the magnitude of an earthquake is M=23log(EE0)
that uses the common (base 10) logarithm. This is called the Moment Magnitude Scale (MMS), an alternative to the more well known Richter Scale. One earthquake has magnitude 3.9
on the MMS. If a second earthquake has 700
times as much energy as the first, find the magnitude of the second quake.

The magnitude of the second earthquake was

Answers

The magnitude of the second earthquake is given as follows:

5.80.

How to obtain the magnitude of the second earthquake?

The magnitude of an earthquake is given by the equation presented as follows:

[tex]M = \frac{2}{3}\log{\left(\frac{E}{E_0}\right)}[/tex]

The first earthquake has a magnitude of 3.9, hence it's energy is obtained as follows:

[tex]3.9 = \frac{2}{3}\log{\left(\frac{E}{E_0}\right)}[/tex]

[tex]\log{\left(\frac{E}{E_0}\right)} = \frac{3.9 \times 3}{2}[/tex]

[tex]\log{\left(\frac{E}{E_0}\right)} = 5.85[/tex]

As the power of 10 is the inverse function of the logarithm, we have that:

[tex]\frac{E}{E_0} = 10^5.85[/tex]

[tex]\frac{E}{E_0} = 707946[/tex]

[tex]E = 707946E_0[/tex]

The second earthquake has 700 times as much energy as the first, hence the energy is of:

[tex]E = 700 \times 707946E_0[/tex]

[tex]E = 495562049E_0[/tex]

Then the magnitude of the second earthquake is given as follows:

[tex]M = \frac{2}{3}\log{\left(\frac{495562049E_0}{E_0}\right)}[/tex]

[tex]M = \frac{2}{3}\log{(495562049)}[/tex]

M = 5.80.

A line that has a slope or 1/5 and passes through (-10,4)

Answers

The Equation of the line which has a slope of 1/5 and passes through (-10,4) will be  [tex]y = \frac{1}{5} x + 6[/tex] .

Given, We have the slope of the line = 1/5 and a  point (-10,4) though which the line passes. We know that the form of a linear line is y=mx + c (slope intercept form) where m is the gradient/slope of the line and c is the point where it intercepts the y axis on the graph. We can directly put the value slope in the place of m.

To find C , we can put the coordinates of the given point in the equation to solve for C. Therefore :

⇒ y = mx + c

⇒y =  1/5 x + c

⇒4 = 1/5 x (-10) + c

The set S={1,2,3,….,12} is to be partitioned into three sets A,B,C of equal size, thus A∪B∪C=S, A∩B=B∩C=A∩C=ϕ. Thus number of ways to partition S is

Answers

The number of ways to partition set S into three sets A, B, and C of equal sizes is 495.

The number of ways to partition S into three sets of equal sizes can be calculated using the formula: nPr=n!/(r!(n−r)!), where n is the total number of elements in the set and r is the number of elements in each partitioned set.

In this case, n=12 and r=4. Therefore, the number of ways to partition S into three sets A, B, and C of equal sizes is 12P4 = 12!/(4!(12−4)!) = 495.

In calculation way step by step,

We know that n = 12 and r = 4.

Calculate 12!.

12! = 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 479001600

Calculate 4!.

4! = 4 x 3 x 2 x 1 = 24

Calculate (12 - 4)!

(12 - 4)! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40320

Calculate nPr.

nPr = n!/(r!(n - r)!) = 479001600/(24 x 40320) = 495

Thus, the number of ways to partition set S into three sets A, B, and C of equal sizes is 495.

Answers

The probability of selecting a person at random is p(w and f) is 0.0216 or 2.16%.

The probability of an event occurring and another event occurring is found by using the multiplication rule of probability, which states that the probability of two events occurring together is equal to the product of the probabilities of each event occurring independently.

In this case, we are looking for the probability of a person being born in the winter (p(w)) and the probability of a person being born in the fall (p(f)), so we would calculate:

p(w and f) = p(w) * p(f)

Using the information provided, we know that:

p(w) = 12% = 0.12

p(f) = 18% = 0.18

p(w and f) = 0.12 * 0.18 = 0.0216 or 2.16%

Given g(x)=ſ8(t)dt , find the first four nonzero terms and the general term for the power series expansion of g(x) about x=0. c. Find the interval of convergence of the power series for g(x).

b) The first four nonzero terms of the power series expansion of g(x) about x=0 are 3x, -x^3, 3/5x^5, -3/7x^7.

c) The interval of convergence for the power series of g(x) is (-sqrt(5/3), sqrt(5/3)).

What is a function?

A function is a mathematical relationship between two variables, often denoted as "f(x)" or "y = f(x)". A function assigns a unique output to each input within its domain. In other words, for every value of x, there is a corresponding value of y, and each value of x can only correspond to one value of y.

a. To find the first four nonzero terms and the general term for the power series expansion of f(t) about t=0, we need to find the Taylor series of f(t) centered at 0. The general term of a Taylor series is given by:

f(t)^(n) / n! * (t-0)^n

The Taylor series of f(t) = 3/(1+t^2) centered at 0 is:

f(t) = 3 - 3t^2 + 3/3t^4 - 3/5t^6 + ...

The first four nonzero terms of the Taylor series are 3, -3t^2, 3/3t^4, -3/5t^6

b. To find the first four nonzero terms and the general term for the power series expansion of g(x) = ∫f(t)dt about x=0, we need to integrate the Taylor series of f(t) term by term.

g(x) = ∫f(t)dt = (3t - 3/3t^3 + 3/5t^5 - ...) from 0 to x

g(x) = 3x - 3/3x^3 + 3/5x^5 - ...

The first four nonzero terms of the power series expansion of g(x) about x=0 are 3x, -x^3, 3/5x^5, -3/7x^7

c. The interval of convergence of a power series is the set of values of x for which the series converges. To find the interval of convergence for g(x), we can use the ratio test.

The ratio test states that if the limit of |a(n+1)x^(n+1)|/|a(n)x^n| as n approaches infinity is less than 1, the series converges for all x.

|3/7x^7|/(|3/5x^5|) = |x^2|/(|3/5|) < 1 when |x| < sqrt(5/3)

So, the interval of convergence for the power series of g(x) is (-sqrt(5/3), sqrt(5/3)).

Hence,

a) The first four nonzero terms of the Taylor series are 3, -3t^2, 3/3t^4, -3/5t^6

b) The first four nonzero terms of the power series expansion of g(x) about x=0 are 3x, -x^3, 3/5x^5, -3/7x^7.

c) The interval of convergence for the power series of g(x) is (-sqrt(5/3), sqrt(5/3)).

The missing value in the solution to the equation is 4. The value of x is 4 and y is -6 which is (4, -6).

What is solution to a equation?

A solution to an equation is a value or values that make the equation true. For example, if the equation is x + 3 = 7, then the solution to the equation would be x = 4.

To solve an equation, you must use a combination of addition, subtraction, multiplication, division, and algebraic manipulations to isolate the unknown variable. For instance, to solve the equation x + 3 = 7, you would subtract 3 from both sides of the equation to find x = 4.

It is important to note that an equation may have more than one solution. For example, the equation x2 + 4 = 0 has two solutions, x = 2 and x = -2.

In some cases, equations may not have a solution. This happens when the equation is not true for any value of the unknown variable. For example, the equation 0 = 1 is not true for any value of x, so it does not have a solution.

In summary, a solution to an equation is a value or values that make the equation true. To solve an equation, you must use a combination of addition, subtraction, multiplication, division, and algebraic manipulations to isolate the unknown variable. An equation may have multiple solutions or no solution at all.

The given equation is 4x + y = 10.

We have the value of y is -6,

Find the volume of a square based pyramid with a base length of 9 and a height of 11

Answers

Answer: It is 36cm the height of it and the length W times L

Step-by-step explanation:

The formula for the volume of a square-based pyramid is:

V=(s²•h)/3, where V=volume, s=length of the square, and h=height of the pyramid.

To find the volume of any solid object, the area of the base must be found first. The base of the pyramid is a square. By definition, squares have 4 congruent sides. The formula for the area of a square is A=s•s, which simplifies to A=s², where “s” is a side length of a square. So, because the base length is 9, then the other 3 sides of the square base area also 9.

Let’s input the values into the volume formula when s=9 and h=11:

V=[(9)²•(11)]/3

Simplify using PEMDAS:

V=[81•11]/3

V=891/3

V=297

Mary owes $13564 income tax.

What is income tax?

Governments apply income taxes as a sort of tax on the income produced by people and businesses under their control. Government duties, public services, and citizen goods are all paid for through income tax revenue.

Given that the taxable income is $68,562.

Income tax is the tax charged on an individual's or entity's income

Using the table as a guide, $68,562 falls within the income range $31,850 - $77,100

So, the tax is $4386 added to 25% of the excess over $31850

This is calculated as:

tax = $4386 + 25%(income - 31,850)

In our case,

income = $68562

Substitute $68,562 for income

Tax = $4386 + 25%(68,562 - 31,850)

Solve the expression in the bracket

tax = 4386 + 9178

Add the terms of the expression

tax = 13,564

therefore, Mary owes $13564 in income tax.

Answers

Thomas invested $3,000 into a bank account with a 5% interest return compounded annually. then the following equations indicates the total amount of money 3000(1.05)^1/16

Thomas invested $3,000 into a bank account with a 5% return compounded annually.

A: represents the current balance or compound amount in the account.

P: represents the principal (the original amount deposited).

R: annual interest rate (in decimal form).N: the number of times per year that interest is compounded .T: time in years the money has been invested.

The formula of interest is A=P (1+r)ⁿ

A=Final amount  

P= Principal ( deposit invested)  

r= interest rate

n= time

So,  in this case

P=$3,000

r= 5% or 0.05

inquiry HOW can you use a bar diagram to show a percent of change?​

Answers

A bar diagram can be used to show a percent of change by the method of comparing two bars.

What is a bar diagram?

Bar graphs or bar charts are visual depictions of groups of data that are made up of vertical or horizontal rectangular bars with lengths that are equal to the data's measure.

A bar diagram can be used to show a percent of change by comparing the size of two or more bars. The bars can represent the original value and the final value, and the difference in size between the two bars will indicate the percent of change.

For example, if the original value is represented by a bar that is 10 units tall and the final value is represented by a bar that is 12 units tall, the percent of change would be 20% (the difference in height between the two bars divided by the original value).

The percent of change can also be labeled or annotated on the graph.

Therefore, bar graph is helpful in denoting the percent of change.

What is the solution to the equation? 3|x| − 1 = 8


x = 3 or 9


x = −9 or 9


x = −3 or 3


x = −3 or −9

please help

Answers

Answer:

x = 3

Step-by-step explanation:

3|x|- 1= 8

=3x = 8 + 1

=3x = 9

=3x/3 = 9/3

x = 3.

Answer:

The equation is 3|x| - 1 = 8. To solve this equation, we first need to consider the absolute value of x.

The absolute value of x is defined as |x| = x for x ≥ 0, and |x| = -x for x < 0.

We have 3|x| - 1 = 8, so we have to consider two cases:

x ≥ 0: in this case, |x| = x and we have 3x - 1 = 8, which gives x = 3 or x = 9.

x < 0: in this case, |x| = -x and we have 3(-x) - 1 = 8, which gives -3x - 1 = 8, and then x = -3 or x = -9.

So the solution to the equation is x = 3 or 9 or x = -3 or -9.
