Answer:

1/2 + 1/4 + 1/12 + 8333/10000

Answer:

Step-by-step explanation:

Method 1:

The slope-intercept of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We have the equation of a line in the point-slope form:

[tex]y-4=2(x-6)[/tex]

Convert it the the slope-intercept formula:

[tex]y-4=2(x-6)[/tex]            use the distributive property

[tex]y-4=2x-12[/tex]             add 4 to both sides

[tex]y=2x-8\to b=-8[/tex]

Method 2:

The y-intercept is for x = 0. Put x = 0 to the equation:

[tex]y-4=2(0-6)[/tex]

[tex]y-4=2(-6)[/tex]

[tex]y-4=-12[/tex]           add 4 to both sides

[tex]y=-8[/tex]

Answer:

Jump discontinuities - No defined limit; the left-handed and right-handed limits will be different, converging at two different finite values

Removable - The limit at this point is defined; the left and right-hand limits both converge on the same value

Asymptotic - The left-and-right-handed limits at this point will either tend to ∞ or -∞

|x-4| <3

=>. x-4<3 or -(x-4)<3

=>. x-4<3 or x+4>3

=>. x<7 or x>1

So solution is x>1 & x<7. =x€(1,7)

Answer:

Step-by-step explanation:

The perimeter of the given triangle:

P = (2x + 1) + (x + 2) + (3x - 9) and P = 36 cm.

Therefore we have the equation:

2x + 1 + x + 2 + 3x - 9 = 36          combine like terms

(2x + x + 3x) + (1 + 2 - 9) = 36

6x - 6 = 36      add 6 to both sides

6x = 42          divide both sides by 6

x = 7

To the nearest tenth, the area of the circle is 112.9 square units.

Answer:

434

Step-by-step explanation:

2(wl+hl+hw)

Answer: the surface is 434 square feet.

Step-by-step explanation:

you can use the formula of right rectangular is 2(wl+wh+lh). The rectangular prism has 6 faces. So the surface area is 434 square feet.

B and D are clearly permutation. A and B are selections but arrangement should be done for A where as C only requires selection so C is the combination.

The example which describes combination is:

Combination--

It is a method of choosing or selecting some items from a group of items.

The formula for choosing r items out of a total of n items is given by the formula:

[tex]n_C_r=\dfrac{n!}{r!\times (n-r)!}[/tex]

Also, if we are selecting as well as arranging some items from a group of items then that method is known as a method of permutation.

A)

Selecting the best cake and runner up best cake from a cake decorating competition.

In this case we are choosing as well as arranging the best and runner up cake according to their ranks.

Hence, it will be a process of permutation and not combination.

B)

The number of ways 6 people can arrive at a party if no one arrive at the same time.

Again it is a problem of permutation because we have to find the number of ways the people can arrive i.e. arranging people in different orders they may arrive.

C)

Selecting 5 CD's to take with you on a trip from a collection of 30 CD's.

This is a method of combination.

Since we have to select some items from a set of items.

D)

The number of ways triplets can be born.

This is again a process of permutation.

Since there are different order they may come.

Answer:

f(x)= x^3-5x^2-23x-12

Step-by-step explanation:

Given:

function f(x) divided by x + 2, the quotient is x2 – 7x – 9 and the

remainder is 6

When a polynomial f(x) is divided by any another polynomial d(x) and there is q(x) and r then it can be written as:

f(x)= d(x)q(x) + r

Now putting values of d(x)= x+2, q(x)= x2 – 7x – 9 and r=6, we get

f(x)= (x+2)(x^2-7x-9)+6

f(x)= x^3 -7x^2-9x+2x^2-14x-18+6

    = x^3-5x^2-23x-12 !

Final answer:

To find the function given a quotient and remainder when divided by x + 2, combine the terms to get f(x) = x² - 7x - 3. The resulting function f(x) is in standard form.

Explanation:

The function f(x) is a polynomial that can be expressed as f(x) = x² - 7x - 9 + 6/(x + 2). Finding the function in standard form involves combining the quotient and remainder terms.

To write it in standard form, simplify the expression to f(x) = x² - 7x - 3.

Therefore, the function f(x) = x² - 7x - 3.

Answer: 21

Step-by-step explanation:

we have two simple equations:

1) 70=100%

2) x=30%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

70/x=100%/30%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 30% of 70

70/x=100/30

(70/x)*x=(100/30)*x - we multiply both sides of the equation by

70=3.33333333333*x - we divide both sides of the equation by (3.33333333333) to get x

70/3.33333333333=x

The fore, the answer is 21

Answer:

21

Step-by-step explanation:

30% of some quantity is equivalent to 0.30 times that quantity.

In this case, 30% of 70 is 0.30(70) = 21.

Answer: Slope of the line is -9/7

Step-by-step explanation:

Given :

Points : (10,9) and (3,18)

Now slope of line when two points are given

m=[tex]\frac{y2-y1}{x2-x1}[/tex]

Slope = [tex]\frac{18-9}{3-10}[/tex]

m=[tex]\frac{9}{-7}[/tex]

m=[tex]\frac{-9}{7}[/tex]

This is an improper fraction since numerator is greater than the denominator

Hence slope of the line is -9/7

Diameter of circle=6 feet

then

radius=diameter/2

=6/2

=3 feet

The area of circle is given by  

A = πr^2

where r is the radius of the circle

Putting the values of pi and r

A =(3.14)(3)^2

=3.14*9

=28.26 sq. feet

Rounding off to the nearest tenth

A=28.3 sq. feet

So, 28.3 sq. feet need to be painted for the base circle ..

Answer:

Degree 9.

Step-by-step explanation:

The degree is the sum of all the exponents.

So it is 2 + 3 + 4 = 9.

The degree is the sum of all the exponents  5r^2s^3t^4, So it is 2 + 3 + 4 = 9.

The degree sum formula says that if you add up the degree of all the vertices in a (finite) graph, the result is twice the number of the edges in the graph. There's a neat way of proving this result, which involves double counting: you count the same quantity in two different ways that give you two different formulae.

The degree is the sum of all the exponents  5r^2s^3t^4

So it is 2 + 3 + 4 = 9.

Degree of the Term is the sum of the exponents of the variables. Example. 2x 4y 3 4 + 3 = 7 7 is the degree of the term. 5x-2y 5 NOT A TERM because it has a negative exponent.

Sooo whats the question

The circumference of a circle is found by multiplying the diameter by PI.

Answer:

Step-by-step explanation:

We have:

two rectangles 2 × 3

two rectangles 3 × 5

two rectangles 2 × 5

Calculate the areas:

A₁ = (2)(3) = 6

A₂ = (3)(5) = 15

A₃ = (2)(5) = 10

The Surface Area:

S.A. = 2A₁ + 2A₂ + 2A₃

S.A. = (2)(6) + (2)(15) + (2)(10) = 12 + 30 + 20 = 62

The function f(x) = (x^2 - 4x - 12) / (x + 2) is a rational function, which is a ratio of two polynomials. To find its discontinuity, we identify values of x which makes the denominator zero, in this case x = -2, making this the function's discontinuity.

The function given is f(x) = (x^2 - 4x - 12) / (x + 2). This is a rational function, which is a ratio of two polynomial functions - in this case, a quadratic function (x^2 - 4x - 12) and a linear function (x + 2).

To find the discontinuity of a rational function, we need to identify the values of x that make the denominator zero since division by zero is undefined. In this case, that's when x = -2. Thus, this function has a discontinuity at x = -2.

Note that this does not factor into the asymptote of the function as some might believe, but it's instead a point at which the function is undefined. "Graphing this function would show a hole at x = -2".

Answer:

The domain is {x I x ≠ 13} ⇒ the last answer

Step-by-step explanation:

* Lets talk about the composite function

- It is a function is found from two given functions by applying one

 function into the second function.

- The applying function is the domain of the second function

- (f °g)(x) means g(x) is applying into f(x)

* Lets solve the problem

∵ f(x) = x + 7

∵ g(x) = 1/(x -13)

- To apply g(x) into f(x) replace x in f(x) by g(x)

∴ f(g(x)) = f(1/(x - 13)) = 1/(x - 13) + 7

- The domain of the function is all values of x which make the function

  defined

- The domain is all real numbers except the value which makes

 the denominator = 0

- To find this value put the denominator = 0

∵ The nominator of (f ° g)(x) is x - 13

∴ Put x - 13 = 0

∴ x - 13 = 0 ⇒ add 13 to both sides

∴ x = 13

∴ The domain of (f ° g)(x) is all real numbers except x = 13

* The domain is {x I x ≠ 13}

Answer:

Step-by-step explanation:

A false negative is when you test negative when you should have tested positive

A false positive is when you test positive on a test you should have been negative on

Testing positive for a disease when you don't really have the disease is option C. False positive.

False positive is defined as the error caused by the false positive of an actual negative condition.

There are mainly two kinds of errors in probability.

One is false positive and the other one is false negative.

False positive error as discussed above is the false positive statement for an actual negative condition.

For example, a test result showing that you are pregnant while you are actually not.

False negative errors are those formed by the false negative for an actual positive statement.

For example, a test result showing that you are not pregnant while you are actually pregnant.

Here, since the test result is positive but actually you don't have the disease is a false positive.

Hence the given statement is false positive.

Answer:

1.400 as a common fraction is 7/5

as a percentage 140%

Step-by-step explanation:

1.4 written as a fraction is;

[tex]\frac{14}{10}[/tex]

simplifying we have;

[tex]\frac{14}{10}=\frac{7}{5}[/tex]

Converting to percentage we simply multiply by 100.

[tex]\frac{7}{5}*100=140[/tex]

For this case we have that if "and" varies directly proportional to "x", it follows that:

[tex]y = kx[/tex]

Where:

k: It is the constant of proportionality.

Then, we look for the value of "k":

[tex]9 = k (5)\\k = \frac {9} {5}[/tex]

So, now we look for the value of "y" when x = 20.

[tex]y = \frac {9} {5} (20)\\y = \frac {180} {5}\\y = 36[/tex]

Thus, the value of y is 36

Answer:

[tex]y = 36[/tex]

Answer:

Final answer is y=36 and the constant of variation is k=9/5.

Step-by-step explanation:

Given that the variable y varies directly to the variable x.

Then we can write equation as y=kx

Were k is the constant of variation.

Given that If y = 9, then x = 5.

Plug these values into above equation, we get:

y=kx

9=5k

5k=9

k=9/5

Now we need to find the value of y when x = 20. So plug x = 20 and k=9/5 into above formula

y=kx

y=(9/5)(20)

y=180/5

y=36

Hence final answer is y=36 and the constant of variation is k=9/5.
