Answer:

(0 , 4)

Step-by-step explanation:

The Y-intercept is when a line crosses sector y at any point. This means x will be zero. Simply to find the y-intercept from this quadratic function, just look at where the line crosses the y-line.

This clearly passes at (0,4), therefore (0,4) is the y-intercept.

Answer: Hi there ^^ oki so ima explain what these are/mean
So for starters this is used in math and isnt really useful but u got to do the work sadly so.
the mean is the arithmetic average of a set of given numbers.
the median is the middle in sorted numbers (after u sort the given numbers), ascending or desending, list of numbers can be more descripited of that data set than the average.
the mode is the value that appears most frequently, for example "the mode of {4,2,4,3,2,2} is 2 because it accurs 3 times, so in short words the mode is the number used the Most,
And lastly the Range is the differance between the highest and the lowest values in a set of numbers.

i hope this helps u out! ^^ ~xlXCherryColaXlx

Answer:

2n*m. when there is a one in front of a letter, it is immediately just the letter

Since the diameter for a segment is 68 centimeters long, we must divide that number by 4, since there are four circles. Next, we get 17.

Then, we use the formula for solving a circle, which is [tex]A = \pi r^2[/tex]. Plug in 8.5 (half of 17) for the radius, and then convert pi into 3.14. The equation should now look something like this: [tex]A = 3.14 * 8.5^2[/tex]. When solving, we get 265.865 for one circle only. We next multiply 256.856 by 4 since there are four circles. After multiplying you should get a total of 907.46 centimeters squared.

If this isn't correct, then do the same thing, but the radius is 34 centimeters.

[tex]8 - 4x > - 2x - 12x - 3[/tex]

[tex]8 - 4x > - 14x - 3[/tex]

[tex] - 4x + 14x > - 3 - 8[/tex]

[tex]10x > - 11[/tex]

[tex]x = - 1.1[/tex]

Answer:

[tex]x > \frac{-11}{10}[/tex]

Step-by-step explanation:

Step 1:  Distribute

[tex]4(2 - x) > -2x - 3(4x + 1)[/tex]

[tex](4*2)+(4 * (-x)) > -2x + (-3 * 4x) + (-3 * 1)[/tex]

[tex]8 - 4x > -2x - 12x - 3[/tex]

Step 2:  Combine like terms

[tex]8 - 4x > (-2x - 12x) - 3[/tex]

[tex]8 - 4x > -14x - 3[/tex]

Step 3:  Add 14x to both sides

[tex]8 - 4x + 14x > -14x - 3 + 14x[/tex]

[tex]8 + 10x > -3[/tex]

Step 4:  Subtract 8 from both sides

[tex]10x + 8 - 8 > -3 - 8[/tex]

[tex]10x > -11[/tex]

Step 5:  Divide both sides by 10

[tex]\frac{10x}{10} > \frac{-11}{10}[/tex]

[tex]x > \frac{-11}{10}[/tex]

Answer:  [tex]x > \frac{-11}{10}[/tex]

Answer:

13) x = 19

14) x = 12.4

Step-by-step explanation:

So, for 13, we know that the whole thing is 90 degrees, a right angle.

So, (4x - 17) + 31 = 90

Now, we'll subtract 31 from 90 to figure out the other angle.

4x - 17 = 59

Now, add seventeen to both sides to get 4x alone...

4x = 76

Divide each by four!

x = 19

Now, to check, we plug this x value into our first equation:

(4(19) - 17) + 31 = 90

(76 - 17) + 31 = 90

(59) + 31 = 90

90 = 90 :: true!

________________________________________

For 14, we know that the total must be 180, because it's a straight angle.

So, (5x + 22) + 96 = 180  
Again, subtract the known angle from each side:

5x + 22 = 84

Subtract 22 from each side to get the exponent by itself...

5x = 62

Divide each side by 5:

x = 12.4

Now, plug it in to check.....

(5*12.4) + 22 + 96 = 180

62 + 22 + 96 = 180

84 + 96 = 180

180 = 180 :: true!

Step-by-step explanation:

Answer:

  f(x) = 3sin(3.1416(x +4)/7)

Step-by-step explanation:

You want the equation of a sine function with an amplitude of 3 and having one cycle between the points (-11, 0) and (3, 0), where it has negative slope.

The equation will generally be of the form ...

  f(x) = (amplitude)·sin(2π/(period)·(x-(horizontal translation)))

Here, the amplitude is 3 units, the period is (3 -(-11)) = 14 units, and the horizontal translation from the origin to the positive-going midline crossing is 4 units to the left.

Then f(x) is ...

  f(x) = 3·sin(2π/14(x -(-4))

  f(x) = 3·sin(3.1416/7(x +4))

Answer:

48.2 feet

or

578.4 inches

Step-by-step explanation:

Perimeter is the distance around the shape or in this case the room. Assuming the room is a rectangle you would have two walls of the same length totaling 4 walls.

To find the perimeter add up 14.5 + 14.5 + 9.6 + 9.6 = 48.2 feet

Since it askes for the answer in inches you have to convert from feet to inches by multiplying your answer by twelve.

Answer:

All of them are true.

Step-by-step explanation:

The symbol ≅  is used to show congruence between two shapes.

Congruency means that the shapes have the same shape and size.

This means that the two shapes are the same.

This means that all sides are going to be the same, so the first two statements are true.

This also means that the angles are the same, so the last two statements are also true.

Simplify  

           x2 + 5x + 4

Trying to factor by splitting the middle term

1.1     Factoring  x2 - x - 2

The first term is,  x2  its coefficient is  1 .

The middle term is,  -x  its coefficient is  -1 .

The last term, "the constant", is  -2

Step-1 : Multiply the coefficient of the first term by the constant   1 • -2 = -2

Step-2 : Find two factors of  -2  whose sum equals the coefficient of the middle term, which is   -1 .

     -2    +    1    =    -1    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -2  and  1

                    x2 - 2x + 1x - 2

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-2)

             Add up the last 2 terms, pulling out common factors :

                    1 • (x-2)

Step-5 : Add up the four terms of step 4 :

                   (x+1)  •  (x-2)

            Which is the desired factorization

Trying to factor by splitting the middle term

1.2     Factoring  x2+5x+4

The first term is,  x2  its coefficient is  1 .

The middle term is,  +5x  its coefficient is  5 .

The last term, "the constant", is  +4

Step-1 : Multiply the coefficient of the first term by the constant   1 • 4 = 4

Step-2 : Find two factors of  4  whose sum equals the coefficient of the middle term, which is   5 .

     -4    +    -1    =    -5

     -2    +    -2    =    -4

     -1    +    -4    =    -5

     1    +    4    =    5    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  1  and  4

                    x2 + 1x + 4x + 4

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x+1)

             Add up the last 2 terms, pulling out common factors :

                   4 • (x+1)

Step-5 : Add up the four terms of step 4 :

                   (x+4)  •  (x+1)

            Which is the desired factorization

Canceling Out :

1.3    Cancel out  (x+1)  which appears on both sides of the fraction line.

Final result :

 x - 2

Answer:

10

Step-by-step explanation:

find the square root of the sum of the squares

The length of the hypotenuse for the given right angled triangle is 10 units.

Pythagoras theorem states that the square of the hypotenuse is equivalent to the square of the base and perpendicular.

We can write the formula for Pythagoras theorem as -

(hypotenuse)² = (base)² + (perpendicular)²

Given is to find the length of the hypotenuse in the right angled triangle shown.

Using the Pythagoras theorem, we can write that -

(hypotenuse)² = (base)² + (perpendicular)²

(hypotenuse)² = (5√2)² + (5√2)²

(hypotenuse)² = 2 x (5√2)²

(hypotenuse)² = 2 x 25 x 2

(hypotenuse)² = 100

(hypotenuse) = 10

Therefore, the length of the hypotenuse for the given right angled triangle is 10 units.

Answer

7/3

Step-by-step explanation:

Find f of x and f of y

F(x,y) = 2x + 27 - 16x + 4y + 20, f of x = -14

F(x,y) = 2x + 2y - 16x + 4y + 20, f of y = 6

Find the fist partial derivative

f of x = -14

f of y = 6

Subsitude f of x = 14 and f of y = 6 into dy/dx = - f of x / f of y

reduce the fraction

dy/dx = - 14/6 = - - 7/3 = 7/3
