Answer:

r = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Given the proportional equation

y = rx ← r is the constant of proportion

Divide both sides by x

[tex]\frac{y}{x}[/tex] = r

Use any ordered pair from the table.

Using (8, 2 ) , then

r = [tex]\frac{2}{8}[/tex] = [tex]\frac{1}{4}[/tex]

Answer:

1/4

Step-by-step explanation:

Multiplying the input (x) by (1/4) results in the output.  This is direct proportion, and the constant of proportionality is (1/4).

Step-by-step explanation:

10) First find the capacity of the swimming pool.

Volume of the swimming pool= length * depth  *width

                                                 = 15 * 1.5 * 5

                                                  = 112.5 cubic meter

1 cubic meter= 1000 liters

112.5 cubic m = 112.5* 1000 = 112,500 liters

Quantity of salt added to every 10 000 liters = 2 Kg

Quantity of salt added to  112,500 liters =  [tex]\dfrac{2}{10000}*112500[/tex]

       = 22.5 Kg

Answer:

Step-by-step explanation:

If Anna's dad is 36 and is 9 times her age, then Anna's age is 36/9 which is 4.

Check yourself: Anna is 4. Her dad is 9 times her age and 4(9) = 36.

Answer:

x — 4

Step-by-step explanation:

Difference means subtraction, so x — 4 is the expression for your question.

[tex] \implies \sqrt{ \dfrac{36}{169} } [/tex]

[tex] \implies \sqrt{ \dfrac{6 \times 6}{13 \times 13} } [/tex]

[tex] \implies \sqrt{ \dfrac{ {6}^{2} }{ {13}^{2} } } [/tex]

[tex] \implies \sqrt{ \left(\dfrac{ {6} }{ {13} } \right)^{2} } [/tex]

[tex] \implies {\left(\dfrac{ {6} }{ {13} } \right)^{2 \times }}^{ \frac{1}{2} } [/tex]

[tex] \implies \left(\dfrac{ {6} }{ {13} } \right)[/tex]

This is your answer.

The answer is 6/13 sq rt of 36 is 6 and sq rt of 169 is 13.

Answer:

The general equation of a slope-intercept form is as below;

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

m » slope / gradient

c » y - intercept

x » x - intercept

Since our equation is 5x + 2y = -6, make y the subject:

[tex]5x + 2y = - 6 [/tex]

subtract 5x from either sides:

[tex](5x + 2y) - 5x = - 6 - 5x \\ 2y = - 5x - 6[/tex]

apply the division rule of equality:

[tex] \frac{2y}{2} = \frac{ - 5x}{2} - \frac{6}{2} \\ \\ { \boxed{ \boxed{answer : \: y = - \frac{5}{2} x - 3}}}[/tex]

slope » -5/2

y - intetcept » -3

Answer:

- 8x + 3

Step-by-step explanation:

(f + g)(x)

= f(x) + g(x)

= - 5x + 3 + (- 3x)

= - 5x + 3 - 3x ← collect like terms

= - 8x + 3

We know

[tex]\\ \sf\longmapsto tan\theta=\dfrac{Perpendicular}{Base}[/tex]

[tex]\\ \sf\longmapsto tan(<R)=\dfrac{PQ}{PR}[/tex]

The expressions are equivalent to tan R = PQ / PR. Where PQ is perpendicular, and PR is the base.

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

The triangle PQR is given,

∠R=90°

As we know that the tangent is the ratio of the perpendicular and base.

Geometry is defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.

When P is right-angled and R is theta, PQ is perpendicular, and PR is the base if P is right-angled.

tanθ=P/B

tanR=PQ / PR.

Thus, the expressions are equivalent to tan R = PQ / PR. Where PQ is perpendicular, and PR is the base.

Step-by-step explanation:

The division result is: Quotient: [tex]3x^2 + 9x^2 - 107x^2[/tex], Remainder: -33 Here's the polynomial division step by step:    [tex]3x^2 + 1 | 9x^4 - 12x^3 + 103x^2 + 2[/tex]

Step 1: Divide the highest degree term of the dividend by the highest degree term of the divisor:

       [tex]3x^2 + 1 | 9x^4 - 12x^3 + 103x^2 + 2[/tex]

                [tex]9x^4 + 3x^2[/tex]

                    ---------------

                            [tex]-12x^3 + 103x^2[/tex]

Step 2: Multiply the divisor by the result from step 1 (3x^2 + 1) and subtract the result from the dividend:

     [tex]3x^2 + 1 | 9x^4 - 12x^3 + 103x^2 + 2\\[/tex]

                    [tex]9x^4 + 3x^2[/tex]

                    ---------------

                           [tex]-12x^3 + 103x^2[/tex]

                            [tex]-12x^3 - 4x^2[/tex]

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

                                   [tex]107x^2 + 2[/tex]

Step 3: Divide the highest degree term of the new dividend (107x^2) by the highest degree term of the divisor (3x^2), and perform the division:

       [tex]3x^2 + 1 | 9x^4 - 12x^3 + 103x^2 + 2[/tex]

                    [tex]9x^4 + 3x^2[/tex]

                    ---------------

                            [tex]-12x^3 + 103x^2[/tex]

                            [tex]-12x^3 - 4x^2[/tex]

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

                                     [tex]107x^2 + 2 \\ 107x^2 + 35[/tex]

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

                                                -33

Since the result (-33) has a lower degree than the divisor (3x^2 + 1), we can't proceed with further division.

So, the division result is:

Quotient: [tex]3x^2 + 9x^2 - 107x^2[/tex]

Remainder: -33

Correct Question is:

Divide [tex](9x^4 - 12x^3 + 103x^2 + 2)\ by \ (3x^2 + 1)[/tex]

Answer:

60

Step-by-step explanation:

Greatest common factor of 360 and 150 is 30

that means one side of square-size plots will be 30 m

our total area is 360x150

area of square-size plot is 30x30

360x150/30x30 = 12x5 = 60

Hi ;-)

[tex](r+2)(r-3)=0\\\\r+2=0 \ \vee \ r-3=0\\\\\boxed{r=-2} \ \vee \ \boxed{r=3}[/tex]

Answer:

r = -2 , 3

Step-by-step explanation:

(r + 2)(r -3) = 0

r + 2 = 0                                      ;  r - 3 = 0

Subtract 2 from both sides       ;  add 3 to both sides

    r = -2                                      ; r = 3

r = -2 , 3

A major problem with interval lengths that are too small is that it masks the shape of the distribution.

The interval length used in a distribution may be described as the size of the class or the class width. The interval length is usually important when drawing histograms and other related graphs for a grouped distribution.

The most significant effect of using a class interval which is too small is that it masks the actual shape of distribution, Hence preventing it from being distinct.

For best practice, it is essential that the class interval is of moderate width, hence enabling us to have a distribution which isn't maksed nor exaggerated.

Answer:

Step-by-step explanation:

Those two angles are equal. They are corresponding angles.  In two parallel lines crossed by a transversal. 8 angles are produced. 4 have one value and the other 4 are supplementary to the first four.

These 2 are part of the first group of 4.

So 12x -  8 = 104

12x - 8 + 8 = 104 + 8

12x = 112

x = 9 1/3

Answer:

The answer depends on x.value

Step-by-step explanation:

I. It's linear equation

          y = mx + b

when y is output, x is input, m is slope and b is addition

   So if x = -1

          y = -4/3(-1) - 2

             = 4/3 - 2

             = (4-6)/3

           y = -2/3

   It will be something like this (-1, -2/3) when -1 is x.value, -2/3 is y.value        

You can given x.value be anything like 0, 1, 2, 3 the graph will be like this
