Based on the giving information, what is the measure of the missing length, w?

The required quadratic inequality whose graph is given below is

[tex]y > -\frac{1}{4}x^2 -4x +2[/tex]

What is graph of a function?

At first it is important to know about function

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

Graph of a function f(x) is the collection of all point of the form (x, f(x))

Let the equation be  [tex]y = ax^2 + bx + c[/tex]

The graph passes through (0, 2)

Putting x = 0 and y = 2

c = 2

[tex]y = ax^2 + bx + 2[/tex]

The graph passes through (-12, 14) and (-4, 14)

[tex]14 = (-12)^2a + (-12)b+2\\144a - 12b = 14 - 2\\12(12a- b) = 12\\12a - b = \frac{12}{12}\\12a - b = 1 ... (1)[/tex]

Also

[tex]14 = (-4)^2a + (-4)b + 2\\16a - 4b = 14 - 2\\16a - 4b = 12\\4(4a - b) = 12\\4a - b = \frac{12}{4}\\4a - b = 3 .... (2)[/tex]

Subtracting (2) from (1),

8a = -2

[tex]a = -\frac{2}{8}[/tex]

[tex]a = -\frac{1}{4}[/tex]

Putting the value of a in (2)

[tex]4 \times -\frac{1}{4} - b =3\\-1 - b = 3\\b = -3 - 1\\b = -4[/tex]

The required equality is

[tex]y = -\frac{1}{4}x^2 -4x +2[/tex]

Since the shaded region is the outer region and the line is given dotted,

The required quadratic inequality is

[tex]y > -\frac{1}{4}x^2 -4x +2[/tex]

Step-by-step explanation:

I can't explain every problem, but I will do the first three.

1) We divide the sides by 4 to get x=5

2)We divide by 3 to get x=3

3)Divide by 4 to get x=2

Step-by-step explanation:

4x + 3y = -10

9x + 2y = 6

we have 2 general options :

substitution or elimination.

in substitution we use one equation to express one variable by the other, then use that equality in the second equation and solve for the remaining variable.

like in our case

4x = -10 - 3y

x = (-10 - 3y)/4

in elimination we multiply one or both equations by some factors and then subtract one equation from the other resulting in one equation in one remaining variable.

this is the better method, if substitution leads to more complex fractions.

like in our case.

so, I would multiply equation 1 by 2 and equation 2 by 3, and then subtract e.g. equation 2 from 1 (we could also do it the other direction, it gives the same solutions) :

8x + 6y = -20

- 27x + 6y = 18

------------------------

-19x 0 = -38

-19x = -38

19x = 38

x = 2

and then we pick any of the original equations to get the other variable :

e.g.

4x + 3y = -10

4×2 + 3y = -10

8 + 3y = -10

3y = -18

y = -6

The required proof by Mathematical Induction of 1 / 1 ×2 + 1 / 2 ×3 + 1 / 3 × 4 + ... + 1 / n ( n + 1 ) = n / n + 1 has been in the solution.

To begin, we suppose that the assertion is correct for some integer k.

⇒ 1/1. 2 + 1/2 . 3 + . . . + 1/k . (k+1)  = k/(k+1)    ....(i)

As per Mathematical Induction, the required solution would be as:

Let the LHS be Sk.

Consider the series with one more term, when k = k+1.

We must demonstrate that Sk+1 has the same form as equation (i) but with k substituted by k+1.

Then,

Sk+1 = Sk + 1/(k+1)(k+2)

       = k/(k+1) + 1/(k+1)(k+2)

       = [k(k+2) + 1] / (k+1)(k+2)

       = (k2+2k +1) / (k+1)(k+2)

       = (k+1)2 / (k+1)(k+2)

       = (k+1) / (k+2)

       = (k+1) / ((k+1)+1)

And this has the same form as equation (i) but with k+1 in place of k.

As a result, if it is true for n=k, it must also be true for n=k+1.

When n=1, S1 = 1/1. 2 = 1/2 = 1/1(1+1), hence the assertion is correct.

As a result of the preceding demonstration, it must be true for n= 1+1 = 2.

as well as for n=2+1=3 and so forth for all n numbers.

A probability is given by the division of the number of desired outcomes by the number of total outcomes.

The total number of outcomes when a pair of dice is rolled is given by:

6² = 36.

As each throw has six outcomes.

The outcomes with a sum of 5 are given as follows:

(1,4), (2,3), (3,2), (4,1).

Hence 4 outcomes, and the probability that player A wins is of:

p = 4/36 = 1/9.

The outcomes with a sum of 4 are given as follows:

(1,3), (2,2), (3,1).

Hence the probability that B wins is given by:

p = 3/36 = 1/12.

Then the probability that a player wins on each trial is given by:

p = 4/36 + 3/36 = 7/36.

Given terms of a geometric sequence:

The common ratio of a geometric sequence is found by dividing consecutive terms.  Therefore:

[tex]\implies \dfrac{a_3}{a_2}=\dfrac{a_2}{a_1}[/tex]

Substitute the given terms into the equation and solve for x:

[tex]\implies \dfrac{\sqrt{x}+1}{1}=\dfrac{1}{\sqrt{x}-1}[/tex]

[tex]\implies (\sqrt{x}-1)(\sqrt{x}+1)=1[/tex]

[tex]\implies x+\sqrt{x}-\sqrt{x}-1=1[/tex]

[tex]\implies x-1=1[/tex]

[tex]\implies x=2[/tex]

General form of a geometric sequence:

[tex]\boxed{a_n=ar^{n-1}}[/tex]

where:

Substitute the found value of x into the expressions for the given terms:

Find the common ratio:

[tex]\implies r=\dfrac{a_3}{a_2}=\dfrac{\sqrt{2}+1}{1}=\sqrt{2}+1[/tex]

Therefore, the equation for the nth term is:

[tex]\boxed{a_n=(\sqrt{2}-1)(\sqrt{2}+1)^{n-1}}}[/tex]

To find the 5th term, substitute n = 5 into the equation:

[tex]\implies a_5=(\sqrt{2}-1)(\sqrt{2}+1)^{5-1}[/tex]

[tex]\implies a_5=(\sqrt{2}-1)(\sqrt{2}+1)^{4}[/tex]

[tex]\implies a_5=(\sqrt{2}-1)(\sqrt{2}+1)^2(\sqrt{2}+1)^2[/tex]

[tex]\implies a_5=(\sqrt{2}-1)(3+2\sqrt{2})(3+2\sqrt{2})[/tex]

[tex]\implies a_5=(\sqrt{2}-1)(9+12\sqrt{12}+8)[/tex]

[tex]\implies a_5=(\sqrt{2}-1)(17+12\sqrt{2})[/tex]

[tex]\implies a_5=17\sqrt{2}+24-17-12\sqrt{2}[/tex]

The Center of the circle is (5, -17) and radius of the circle is 29 units.

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

We have given circle in the x, y-plane has the equation;

x² + y² -10x + 34y - 527 = 0

Now we will convert this equation to the standard form of the circle as;

x² -10x + y² + 34y = 527

[x² - 2(5)x] + [y² + 2(17)x] =527

[x² - 2(5)x + 5²] + [y² + 2(17)y + 17²] = 5² + 17² +527

(x - 5)² + (y + 17)² = 25 + 289 +527

(x - 5)² + (y + 17)² = 841

(x - 5)² + (y + 17)² = 29²

By comparing this equation with the standard equation of the circle →

That is;  (x - h)² + (y - k)² = r²

Step-by-step explanation:

The function is not continuous, so the function cannot be exponential, logarithmic, or exponential.

This means the only possibility is that the function is rational.

1.2.1 There are 18 houses in the neighborhood.

1.2.2 The building located next to the park is the hospital.

1.2.3 The business which appears more than all the other businesses in the neighborhood is the Cafe.

1.2.4. The bar scale measures 25 centimeters.

1.2.5 Based on the above measurement, the scale of this street map has a scale factor of 0.005468, compared to the original distance of the neighborhood.

1.2.6 There are 3 more houses in the street at the top than the street at the bottom.

The scale factor is the ratio between two scales of an object.

The scale factor shows how larger or smaller the new scale is compared to the old scale (original measurement).

The formula for the scale factor is as follows:

Scale factor = Dimension of the new scale ÷ Dimensions of the original scale.

1 yard = 91.44 centimeters

50 yards = 4,572 centimeters (91.44 x 50)

The original (larger) dimension of the neighborhood = 50 yards or 4,572 centimeters

Scale (smaller) dimension of the map = 25 centimeters

Scale factor = Smaller dimension/Larger dimensions

= 25/4,572

= 0.005468

The number of houses at the top street = 8

The number of houses at the center street = 5

The number of houses at the bottom street = 5

The total number of houses in the neighborhood = 18

The difference between the top street houses and the bottom street houses = 3 (8 - 5)

The number of cafes = 2

The number of parks = 1

The number of other businesses = 1 each
