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

⇒4 = -2 + c

⇒ 4 +2 = c

⇒c =  6

Putting all the values in equation gives us the linear equation of the line :  [tex]y = \frac{1}{5} x + 6[/tex]

The magnitude of the second earthquake is given as follows:

5.80.

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]

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.

The rebound velocity of the ball, vfx, is 10.0 m/s, calculated using the equation vfx = 2vix - viy, where vix is the initial velocity along the x-axis (4.0 m/s) and viy is the initial velocity along the y-axis (-2.0 m/s).

Using the equation vfx = 2vix - viy, the rebound velocity of the ball is calculated as follows:

vfx = 2(4.0 m/s) - (-2.0 m/s) = 10.0 m/s

1. Identify the initial velocity, vix, of the ball along the x-axis, which is 4.0 m/s.

2. Identify the initial velocity, viy, of the ball along the y-axis, which is -2.0 m/s.

3. Use the equation vfx = 2vix - viy to calculate the rebound velocity of the ball, vfx.

4. Calculate vfx = 2(4.0 m/s) - (-2.0 m/s) = 10.0 m/s.

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)).

Correlation: A correlation is a statement that suggests there is a relationship between two variables, where a change in one variable tends to follow or be associated with a change in another variable.

A correlation is a statement that suggests there is a relationship between two variables. It does not necessarily mean that a change in one variable will cause a change in the other variable, but that a change in one tends to follow or be associated with a change in the other. For example, a correlation could be made between the amount of rainfall a region receives and the number of plants that are able to grow there. If the rainfall increases, then the number of plants that can grow in the region is likely to increase as well. A correlation can be either positive or negative, with a positive correlation meaning that an increase in one variable will likely result in an increase in the other, and a negative correlation meaning that an increase in one variable will likely result in a decrease in the other. Correlation can be used to make predictions, but should not be confused with causation, as correlation does not necessarily imply causation.

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.

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).

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.

It is discovered that the phrase under the division symbol is 3x2 - (b - 2)x - c, meaning that b = 5 and c = 3.

find the roots of  x2 - x - 1  =  0    

--->     Using the quadratic formula, the roots are  [ 1 + sqrt(5) ] / 2   and   [ 1 + sqrt(5) ] / 2.

Placing these values into the equation  x5 - bx - c  =  0,  we get:

x  =  [ 1 + sqrt(5) ] / 2   --->   ( [ 1 + sqrt(5) ] / 2 )5   -  b( [ 1 + sqrt(5) ] / 2 )  -  c  =  0

--->    [ 176 + 80sqrt(5) ] / 32  -  ( [ 1 + sqrt(5) ] / 2 )b  -  c  =  0

multiplying by 32     --->    176  +  80sqrt(5)  -  16b  -  16sqrt(5)b  -  32c  =  0

Using the same steps for x  =  [ 1 - sqrt(5) ] / 2 , we get:     176  -  80sqrt(5)  -  16b  +  16sqrt(5)b  -  32c  =  0

Now, let's combine these two results:      176  +  80sqrt(5)  -  16b  -  16sqrt(5)b  -  32c  =  0

   176  -  80sqrt(5)  -  16b  +  16sqrt(5)b  -  32c  =  0

Subtract the lower equation from the upper:      160sqrt(5)  -  32sqrt(5)b  =  0   --->     160sqrt(5)  =  32sqrt(5)b     --->     b  =  5

Now, substitute this value for b into  176  +  80sqrt(5)  -  16b  -  16sqrt(5)b  -  32c  =  0

--->176  +  80sqrt(5)  -  16(5)  -  16sqrt(5)(5)  -  32c  =  0    

--->176  +  80sqrt(5)   - 80  -  80sqrt(5)  - 32c  =  0

Mary owes $13564 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
