What is the distance between two points ( p,q) and (x,y)?

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²]

So, we will use the distance formula:

Let (2, 5/2) be (x₁, y₁) and let (8/3, 1) be (x₂, y₂).

Now Substitute:

D = √[(1 - (5/2))² + (8/3 - 2)²]

Evaluate the expressions within the parentheses;

D = √[(1 - (5/2))² + (8/3 - 2)²]

D = √[(-3/2)² + (2/3)²]

Evaluate:

D = √[9/4 + 4/9]

Square:

D = √97/6

Hence, the distance, d, between the points (2,5/2) and (8/3,1) will be; 1.6415 units.

The quotient of fifty and five more than a number is ten

Answers

Answer:

This number would be straight out zero  .

Step-by-step explanation:

First it said the quotient of fifty and five MORE than a number is 10, so we first need to focus on the line five MORE than a number is 10, so we know this number is less than the value used in the equation then we focus on the quotient of fifty and, So we know this unknown number lets just say the variable for it is n, then we know that fifty/ n+5=10. So Lets use the associative property to turn this into and some algebra to fifty/10 = n+5, so 50/10 equals to 5, so we know that, 5= n+5, so that would be... n =  0. Hope this helps you answer your question! :)

b. Social Security tax: $14,596.66, Medicare tax: $3,413.70
c. Social Security tax: $662.16, Medicare tax: $341.37
d. Social Security tax: $6,621.60, Medicare tax: $3,413.70

Answers

Answer:

D   Social Security tax: $6,621.60, Medicare tax: $3,413.70

Step-by-step explanation:

Following are the calculation to the Social Security and Medicare tax value:

This Social Security tax is a percent to which both workers and employers must pay [tex]6.2\%[/tex] of employee wages, for a total of [tex]12.4\%[/tex].The state pension, which would be applied to a [tex]\$235,430[/tex] annual wage with a maximum tax liability:

         [tex]\to \$106,800\ is\ 12.4\%\ of\ \$106,800 = 0.124 \times \$106,800 = \$13,243.20[/tex]

Its payroll tax for Medicare is [tex]2.9\%[/tex].This only applies to earned income, which includes salaries and tips from an employer. We are liable for [tex]1.45\%[/tex] of a tax, which would be immediately withheld from your paycheck. The other [tex]1.45\%[/tex] is paid by your company. This Medicare tax would be charged to a [tex]\$235,430[/tex] annual salary with a maximum taxable income:

     [tex]\to \$106,800\ is\ 2.9\%\ of\ \$106,800 = 0.029 \times \$106,800 = \$3,097.20[/tex]

Therefore, the final answer is "$13,243.20 and $3,097.20".

Step-by-step explanation:

B - Brackets

O - Power

D - Division

M - Multiplication

A - Addition

S - Subtraction  

24 - 8 + 8/3 - 8/9 + 8/27 - 8/81

First division

8/3 = 2.66666666667

8/9 = 0.88888888888

8/27 = 0.29629629629

8/81 = 0.09876543209

Then Subtract

24 - 8 = 15

2.66666666667 - 0.88888888888 = 1.77777777779

0.29629629629 - 0.09876543209 = 0.1975308642

Then lastly add

15 + 1.77777777779 + 0.1975308642 = 16.975308642

In these type of questions, the answer have decimals, so we have to round it to near whole number.

So nearest whole number is 17

1) ERROR ANALYSIS: Identify and correct the error in describing the transformation of the parent
function.

Answers

Sadly the question is incomplete, so we can not see the described transformation of the parent function, thus we can't see the error in that description.

What we can do is describe the transformation shown here.

Here we can see the parent function:

f(x) = x^2

This function opens upwards, so what we see in the graph is this function reflected across the horizontal axis (the x-axis). So the transformation is just a reflection across the x-axis.

(notice that it passes through (-1, -1) and (1, -1), so there is no dilation nor contraction)

For a general function f(x), a reflection across the x-axis is just:

g(x) = -f(x)

So here the transformed function is:

g(x) = - x^2

Which of these is a set of inputs and outputs for the function f(x) = 2x + 4 ?

Answers

Answer:

(1, 6), (2, 8), (3, 10)

2(1) + 4 = 6, 2(2) + 4 = 8 and 2(3) + 4 = 10.

Step-by-step explanation:

The set of inputs for the equation f ( x ) = 2x + 4 is

( 1 , 6 ) , ( 2 , 8 ) , ( 3 , 10 )

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be f ( x ) = 2x + 4

f ( x ) = y

Now ,

Let the first point be A ( 1 , 6 )

Let the second point be B ( 2 , 8 )

Let the third point be C ( 3 , 10 )

a)

A ( 1 , 6 )

Substitute the value of x and y in the equation , we get

y = 2x + 4

6 = 2 ( 1 ) + 4

6 = 2 + 4

6 = 6

Hence , the input A ( 1 , 6 ) satisfies

b)

B ( 2 , 8 )

Substitute the value of x and y in the equation , we get

y = 2x + 4

8 = 2 ( 2 ) + 4

8 = 4 + 4

8 = 8

Hence , the input B ( 2 , 8 ) satisfies

c)

C ( 3 , 10 )

Substitute the value of x and y in the equation , we get

y = 2x + 4

10 = 2 ( 3 ) + 4

10 = 6 + 4

10 = 10

Hence , the input C ( 3 , 10 ) satisfies

Hence , The set of inputs for the equation f ( x ) = 2x + 4 is

( 1 , 6 ) , ( 2 , 8 ) , ( 3 , 10 )

To find the solution we need to take equal above equations .

[tex] - 3x + 4x + 2 = - 3x + 3x - 12 \\ [/tex]

[tex]x + 2 = - 12[/tex]

Subtract sides 2

[tex]x + 2 - 2 = - 12 - 2[/tex]

[tex]x = - 14[/tex]

Thus the x-coordinate of the solution must be -14 which is just in the last option.

Thus the correct answer is the last one.

A group of students were discussing whether the relationship on the graph
is a function.

Answers

Answer:

A function is a relationship that maps the elements of a set, the domain, into elements of another set, the range.

The restriction that we have for functions is: The elements on the domain can be mapped into only one element in the range.

Then if:

f(x1) = y1

and

f(x1) = y2

where y1 is different than y2

f(x) is not a function.

Now, in the graph you can see a region where both lines overlap, then for some values of x we have two possible values of y, this means that the graph does not represent a function.

Then:

Ed: He is incorrect because we can have different values in the domain mapped into the same value in the range (like in the case of a line y = b, where we have all the elements in the domain mapped into the same element in the range, b)

Debra: There is something called piecewise functions, that are functions of this type, formed by different pieces.

Alejandro: He is correct.

Antoine: Not because you can write an equation means that the relation is a function. You can write an equation for a circle, but it will not be a function.
