Step-by-step explanation:

If there are 12 sections and Lia paints 8, then Kira paints 4.

The fraction that represents how much Kira has painted of the wall is

4/12.

4/12 can be reduced.

4 and 12 have a common factor of 4 so we will divide top and bottom of 4/12 by 4 giving us 1/3.

Answer:

Step-by-step explanation:

The question is to evaluate the natural logarithm of 5. Natural logarithms are logarithms with base e.

e is the irrational number equal to 2.71828182845904523536028747 ... (being irrational the decimals do not end and do not have a repetition period).

Logarithms are evaluated using tables or scientific calculators.

ln (5) = 1.6094379... it is also an irrational number, so it has infinite decimals with no repetition period.

So, rounding to two decimal numbers, ln (5) = 1.61, which is the option C).

29) 3E minutes before A ⇒ answer B

30) The difference between the greatest possible values is 0 ⇒ answer E

31) r divided by s = 1/3 ⇒ answer A

Step-by-step explanation:

* Lets explain each problem

27)

∵ BE is a quarter circle

∵ The radius of the circle is 6

∵ Point c is on the arc BE

∴ The distance from D to C = 6 ⇒ not depends on the position of c

   because DC is a radius in the quarter circle BE

- In Δ BDE

∵ m∠ D = 90°

∵ DB = DE = 6 ⇒ radii of the quarter circle

- By using Pythagoras Theorem

∴ BE = √ (6² + 6²) = √(36 + 36) = √72 = 6√2

- The perimeter of the quadrilateral ABCD is the sum of the sides

∵ AB = 6 , AD = 6 , CD = 6

- Point C can move from B to E

∴ The length of side BC can b greater than 0(it can not be 0

   because the quadrilateral has 4 sides

∴ The length of BC can not exceed the length of BE because the last

   position of point C to be on the arc BE is point E

∴ The length of BC ⇒ 0 < BC ≤ 6√2

  equal 6√2

∵ P is the perimeter of the quadrilateral ABCD

∴ P = 6 + 6 + 6 + (0 < BC ≤ 6√)

∴ P = 18 + (0 < BC ≤ 6√)

- Add 18 to 0 and 18 to 6√2

∴ 18 < P ≤ 18 + 6√2

- In the figure we have a quadrilateral

- All the arrows represent the exterior angles of the figures

- Use the fact that:

 The sum of all angles around a points is 360°

∵ There are 4 vertices (points) on the quadrilateral

∴ The sum of the all angles around the 4 vertices = 4 × 360 = 1440°

- Use the fact that:

 The sum of the interior angles of any quadrilateral is 360°

∵ The sum of the angles represented by the arrows is the difference

  between the sum of all angles around the 4 vertices and the sum

  of the interior angles of the quadrilateral

∴ The sum of these angles = 1440° - 360° = 1080°

* The sum of the degree measures these angles is 1080°

- In any watch the short arrow-hand represents the hours and the long

 arrow-hand represents the minutes

- The numbers of the hours in the watch from 1 to 12

- The number of minutes between each two hours is 5 minutes, then

  at 1 o'clock the minutes number is 5 , at 6 o'clock the number of

  minutes is 30 , at 9 o'clock the number of minutes is 45 , so we can

  find the number of minutes at any number of hour by multiply the

  number of hour by 5

∵ The number of hours have been replaced by letters

∵ The time on the watch is 45 minutes after 12 o'clock OR

  15 minutes before 1 o'clock

∵ The short arrow-hand pointed between L and A

∵ L is the replacing of 12 o'clock and A is the replacing of 1 o'clock

∵ The long arrow-hand pointed at I

∵ I is the replacing of  9 o'clock

∵ The hour number 9 means 5 × 9 = 45 minutes

∴ The hour hand I has 5I minutes

∴ The time in letter is 5I minutes after L

- This answer is not in the choices

- But the answer of 3E minutes before A means:

∵ E is the replacing of 5 o'clock

∴ 3E = 3 × 5 = 15 minutes

∵ A is the replacing of 1 o'clock

∴ 3E minutes before A means 15 minutes before 1 o'clok

* The answer is ⇒ 3E minutes before A

∵ r² = 9

∴ r = ± √9 = ± 3

∴ r has two values -3 and 3

∵ s² = 25

∴ s = ± √25 = ± 5

∴ s has two values -5 and 5

- To find the greatest value of s - r put s greatest and r smallest

∵ The greatest value of s is 5

∵ The smallest value of r is -3

∴ The greatest value of s - r = 5 - (-3) = 5 + 3 = 8

- To find the greatest value of r - s put r greatest and s smallest

∵ The greatest value of r is 3

∵ The smallest value of s is -5

∴ The greatest value of r - s = 3 - (-5) = 3 + 5 = 8

∴ The difference between the greatest possible values of s - r

   and r - s = 8 - 8 = 0

* The difference between the greatest possible values is 0

- There are 27 cubes each of side length r

- The 27 cubes are arranged to form on single large cube of side

  length s

∵ The volume of any cube is V = L³ , where L is the length of its side

∵ The large cube formed from the 27 small cubes

∴ The volume of the large cube = the volume of the 27 small cubes

∵ The side of the small cube is r

∴ The volume of the small cube is r³

∵ The side of the large cube is s

∴ The volume of the large cube is s³

∴ s³ = 27 r³

- Divide both sides by s³ and 27

∴ s³/(27 s³) = (27 r³)/(27 s³)

∴ 1/27 = r³/s³

- Take ∛  for both sides

∴ ∛(r³/s³) = ∛(1/27)

- The cube root canceled by the power 3 and the cube root of

  1/27 is 1/3

∴ r/s = 1/3

* r divided by s = 1/3

Answer:

Step-by-step explanation:

Answer:

D.  (4, -4).

Step-by-step explanation:

y = -x is a line that has a negative slope of  -1 ( rising to the left)  and passing through the origin. It makes an angle of 45 degrees with the x-axis.

So, for example the point ( 0,1 )will map onto( -1 , 0).

Any point which maps on to itself across this line will have to lie on the line.

If x = 4 y = -x = -4.

The formula h=2A/b indicates a combined variation. As the values of A and B change, the value of H also changes accordingly. Understanding its concept helps in solving related problems.

The formula h=2A/b is a representation of combined variation. Combined variation, or joint variation, occurs when a quantity varies directly with the product of two or more other quantities. In other words, as the values of A and B change, the value of h will also adjust accordingly. Let's break it down:

By understanding the concept of combined variation, solving problems involving such formula will become much easier.

The equation h=2A/b represents combined variation where h varies directly with area (A) and inversely with width (b). The formula indicates how changing one variable affects another in the context of proportional relationships. The mention of molecular cohesion and size pertains to a different scientific context and is not directly related to this mathematical formula.

The formula h=2A/b describes a scenario of combined variation, where h varies directly as the area A and inversely as the width b. Direct variation means that as one variable increases, the other variable increases as well, while inverse variation indicates that as one variable increases, the other decreases. In this case, if the area doubles, h will also double if b remains constant, and if b is halved, h will double, assuming A stays constant.

The provided information about the parameter a describing inter-molecular cohesion and the parameter b describing the effect of molecular size seems to be associated with a completely different context, likely a scientific or chemical formula, rather than the combined variation formula presented in the question. This formula might be relevant to the Born-Oppenheimer surfaces as depicted in Figure 3.1c, which describes a chemical interaction.

Answer:

Part 1) The smallest x-intercept is x=-1

Part 2) The largest x-intercept is x=6

Part 3) The y-intercept is y=-6

Part 4) The vertex is the point (2.5,-12.25)

Part 5) The equation of the line of symmetry is x=2.5

Step-by-step explanation:

we have

[tex]f(x)=x^{2}-5x-6[/tex]

step 1

Find the x-intercepts

we know that

The x-intercept is the value of x when the value of the function is equal to zero

so

equate the function to zero

[tex]x^{2}-5x-6=0[/tex]

The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]x^{2}-5x-6=0[/tex]

so

[tex]a=1\\b=-5\\c=-6[/tex]

substitute in the formula

[tex]x=\frac{-(-5)(+/-)\sqrt{-5^{2}-4(1)(-6)}} {2(1)}[/tex]

[tex]x=\frac{5(+/-)\sqrt{49}} {2}[/tex]

[tex]x=\frac{5(+/-)7} {2}[/tex]

[tex]x=\frac{5(+)7} {2}=6[/tex]

[tex]x=\frac{5(-)7} {2}=-1[/tex]

therefore

The x-intercepts are

x=-1 and x=6

The smallest x-intercept is x=-1

The largest x-intercept is x=6

step 2

Find the y-intercept

we know that

The y-intercept is the value of y when the value of x is equal to zero

so

For x=0

[tex]f(0)=(0)^{2}-5(0)-6[/tex]

[tex]f(0)=-6[/tex]

therefore

The y-intercept is y=-6

step 3

Find the vertex

we know that

The equation of a vertical parabola into vertex form is equal to

[tex]f(x)=a(x-h)^{2}+k[/tex]

where

(h,k) is the vertex

Convert the function into vertex form

[tex]f(x)=x^{2}-5x-6[/tex]

Group terms that contain the same variable, and move the constant to the opposite side of the equation

[tex]f(x)+6=(x^{2}-5x)[/tex]

Complete the square, Remember to balance the equation by adding the same constants to each side

[tex]f(x)+6+2.5^{2}=(x^{2}-5x+2.5^{2})[/tex]

[tex]f(x)+12.25=(x^{2}-5x+6.25)[/tex]

Rewrite as perfect squares

[tex]f(x)+12.25=(x-2.5)^{2}[/tex]

[tex]f(x)=(x-2.5)^{2}-12.25[/tex]

The vertex is the point (2.5,-12.25)

step 4

Find the equation of the line of symmetry

we know that

In a vertical parabola the equation of the line of symmetry is equal to the x-coordinate of the vertex

we have

vertex (2.5,-12.25)

The x-coordinate of the vertex is 2.5

therefore

The equation of the line of symmetry is x=2.5

Both of these are linear equations with different y-intercepts and different slopes.

Let's analyze the lines:

y = 2x:

This is a linear equation with a slope of 2 and a y-intercept at the origin (0,0). This means that for every unit increase in x, y increases by 2. The graph is a straight line that passes through the origin.

y = 2 - x:

This is also a linear equation, but with a slope of -1 and a y-intercept at (0,2). This means that for every unit increase in x, y decreases by 1. The graph is a straight line that intersects the y-axis at the point (0,2).

Now, let's consider their relationship:

Both equations are linear, so their graphs are straight lines.

Therefore, the graphs of these two equations are lines with different slopes. The line represented by y = 2x slopes upwards, while the line represented by y = 2 - x slopes downwards.

[tex]\sqrt{13}[/tex]

Step-by-step explanation:

The median from B intersects the midpoint of AC

Find the midpoint using the midpoint formula

midpoint = [ 0.5(1 - 5), 0.5(- 1 + 3) ] = (- 2, 1 )

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = - 2, 1 ) and (x₂, y₂ ) = (0, 4 )

d = [tex]\sqrt{(0+2)^2+(4-1)^2}[/tex]

  = [tex]\sqrt{2^2+3^2}[/tex]

  = [tex]\sqrt{4+9}[/tex] = [tex]\sqrt{13}[/tex] ≈ 3.6 ( to 1 dec. place )

Let the length = x and the width = y

For the length of fence we have x +x + y = 48 = 2x +y = 48

Rewrite as y = 48 - 2x

For the area we have x * y  = 254

Replace y in the are equation:

x * 48 -2x = 254

Simplify the left side:

48x - 2x^2 = 254

Subtract 254 from both sides:

48x - 2x^2 - 254 = 0

Using the quadratic formula solve for x:

a = -2, b = 48 and c = -254

x = -48 + 4√17/-4

x = 16.123 m.

The length = x = 16.123 meters.

The width = 48 - (16.123*2) = 15.754 meters

Rounding to the nearest centimeter:

Length = 16.1 ( 16 meters and 1 cm)

Width = 15.8 ( 15 meters and 8 cm)

Answer:

The correct answer to this problem is the final option, angle BTA is congruent to angle ATC.

Step-by-step explanation:

To solve this problem, we first have to unpack the meaning of the given information.  First, let's remember that CPCTC means that corresponding parts of congruent triangles are congruent.  This means that the same parts of two different triangles that are stated to be congruent (the same) are thus also congruent (the same).

In this case, triangle BAT and triangle CAT are stated to be congruent. This means that line segment BA and CA are congruent, angles BAT and CAT are congruent, and more because of CPCTC (explained above).

The correct answer to this problem is the final option, angle BTA is congruent to angle ATC. We can figure this out simply by looking at the triangle names.  Angle ATC is the same as angle CTA (the letters are just in reverse order).  From the congruence statement, we can tell that BTA and CTA are congruent angles due to the fact that triangle BAT and CAT are congruent using CPCTC.  Looking at the figure, this makes sense because these two angles appear to be the same measure.

Also, we can eliminate the other answer choices, since they are not corresponding parts of the two triangles (the line segments and angles do not represent two congruent pieces of the triangle - they are not matched up correctly).

If D is correct, then a^2 - b^2 should be further factored producing a different kind of answer, like (a + b)^2(c-d)^2 which is not the same as a^4 - b^4. So D is not correct.

The first step in factoring a^4 - b^4 is (a^2 + b^2)(a^2 - b^2) A doesn't lead you anywhere. A is incorrect. The answer must be B.

a^4 - b^4 = (a^2 -  b^2)(a^2 + b^2)  The first term factors.

a4 - b^4 = (a + b)(a - b) (a^2 +b^2)

Step-by-step explanation: THE ANSWER IS B

Answer:

(23,-4):[tex]\sqrt{545}[/tex] units

Step-by-step explanation:

We are given that M(-19,4)and P(4,0)

We have to find the ordered pair that represents MP and find the magnitude of MP.

MP=P-M

MP=(4,0)-(-19,4)=(4+19,0-4)

MP=(23,-4)

Magnitude of MP=[tex]\sqrt{(23)^2+(-4)^2}[/tex]

Magnitude of MP=[tex]\sqrt{529+16}[/tex]

Magnitude of MP=[tex]\sqrt{545}[/tex] units

Hence, .option c is true.

Answer:c.(23,-4):[tex]\sqrt{545}[/tex] units

Answer:

A 2021

Step-by-step explanation:

Answer:

[tex]4x^5\sqrt[3]{3x}[/tex]

Step-by-step explanation:

The product will be written as:

[tex]\sqrt[3]{16x^7}*\sqrt[3]{12x^9}[/tex]

As both the radicals have same root 3 so,

[tex]= \sqrt[3]{16x^7 * 12x^9}[/tex]

The powers of x will be added as the base is same

[tex]=\sqrt[3]{16*12 * x^{(7+9)}}\\=\sqrt[3]{192x^{16}}\\[/tex]

We have to break the terms so that the powers can be written as a multiple of 3

[tex]=\sqrt[3]{64*3*x^{15}*x}\\ =\sqrt[3]{(4^3)*3*(x^{3*5})*x}\\ Applying\ cube\ root\\= 4x^5\sqrt[3]{3x}[/tex]
