After the picture is reflected along the y-axis, its vertices will have the coordinates P'Q'R.:

[tex]P' = (-3,8)\\Q' = (5,7)\\R'=(0,2)[/tex]

What is coordinates of the vertices?

The triangle's vertices' coordinates are [tex](x_{1} ,y_{1} )[/tex], [tex](x_{2},y_{2})[/tex], and [tex](x_{3},y_{3} )[/tex]. The line that connects the first two is split in the ratio l:k, and the line that runs from the division point to the opposing angular point is divided in the ratio m:k+l.

Given:

Triangle PQR and vertices of triangle are

[tex]P=(3,8)\\Q=(-5,7)\\R=(0,2)[/tex]

The following rule results in a reflection about the y-axis:

                      [tex](x, y) ---- > (-x, y)[/tex]

Using the rule on each of our vertices, we have:

[tex](3, 8) ---- > (-3, 8)\\(-5, 7) ---- > (5, 7)\\(0, 2) ---- > (0, 2)[/tex]

An equivalent expression for 4d⁻³/22d⁹ is: B. 2d⁻³/11d⁻⁹

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

An exponent can be defined as a mathematical operation that is used to raise a quantity to the power of another and it is generally written as bⁿ.

Next, we would write the equation as a quotient:

Expression = 4d⁻³/22d⁹

Expression = 2d⁻³/11d⁹

By applying the law of indices, we have:

Answer:

There were 132 children admitted.

There were 165 adults admitted.

Step-by-step explanation:

Given information:

Define the variables:

Create two equations from the given information and defined variables:

[tex]\textsf{Equation 1}: \quad x+y=297[/tex]

[tex]\textsf{Equation 2}: \quad 3x+7y=1551[/tex]

Solve the first equation for y:

[tex]\implies x+y=297[/tex]

[tex]\implies x+y-x=297-x[/tex]

[tex]\implies y=297-x[/tex]

Substitute the found expression for x into the second equation and solve for y:

[tex]\implies 3x+7y=1551[/tex]

[tex]\implies 3x+7(297-x)=1551[/tex]

[tex]\implies 3x+2079-7x=1551[/tex]

[tex]\implies 2079-4x=1551[/tex]

[tex]\implies 2079-1551-4x=1551-1551[/tex]

[tex]\implies 528-4x=0[/tex]

[tex]\implies 528-4x+4x=0 + 4x[/tex]

[tex]\implies 528= 4x[/tex]

[tex]\implies \dfrac{528}{4}= \dfrac{4x}{4}[/tex]

[tex]\implies x=132[/tex]

Substitute the found value of x into the expression for y and solve for y:

Applying the law of sines, the length of ZY to the nearest hundredth is: 3.30 units.

sin X/x = sin W/w = sin Z/z [according to the law of sines].

Given:

Measure of angle X = 60°

Measure of angle Z (∠XZW) = 180 - 60 - (180 - 83) = 23°

x = WZ = ?

z = XW = 1.5

Plug in the values into sin X/x = sin Z/z

sin 60/WZ = sin 23/1.5

WZ = (sin 60 × 1.5)/sin 23

WZ = 3.32

Find ZY using the sine ratio;

sin ∅ = opp/hyp = ZY/WZ

sin 83 = ZY/3.32

ZY = (sin 83)(3.32)

ZY = 3.30

Therefore, applying the law of sines, the length of ZY to the nearest hundredth is: 3.30 units.

The linear inequality represented by the given graph in the attached image is y > -3x + 6.

Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

The graph of the linear inequality. Let's pick two points from the graph to frame the linear equation

The slope-intercept form of the equation is Where m is the slope and b is the y-intercept is (0,6) from the graph so b=6.

Find out slope m by using the general formula. Pick two points (0,6) and (2,0).

Slope = ( y₂ - y₁)  / ( x₂ - x₁ )

Slope = ( 0 - 6 ) / ( 2 - 6 )

Slope = -3

m = -3

So the equation is y = -3x + 6

Now we check the inequality sign by testing any point on the shaded area let's pick (4,0). let's plug in 4 for x  and 0 for y

y= -3x + 6

0 = -3(4) + 6

0 > -6

Inequality:  y > -3x + 6.

The nth terms of the arithmetic sequences;

I. Tn = 3 + √2 + ( n - 1) √2

ii. Tn = 2/ √3 + ( n - 1) 1/ √3

The formula for the nth term of an arithmetic sequence is expressed as;

Tn = a + ( n - 1)d

Where;

i. a = 3 + √2

d = √2

Substitute the values, we have;

Tn = 3 + √2 + ( n - 1) √2

ii. a = 2/ √3

d = 1/ √3

Substitute the value, we have;

Tn = 2/ √3 + ( n - 1) 1/ √3

Thus, the nth terms of the arithmetic sequences are Tn = 3 + √2 + ( n - 1) √2 and Tn = 2/ √3 + ( n - 1) 1/ √3 respectively

[tex]\[{A^{ - 1}} = \frac{{adjA}}{{|A|}}\][/tex]

[tex]\[{\rm{B}} = \left[ {\begin{array}{*{20}{c}}{33}\\{ - 26}\\{23}\end{array}} \right]\][/tex]

So, we will have to find [tex]A^{-1}[/tex], for that, we will first find the determinant of matrix A, that is |A|, then we will find the cofactors of matrix A, take its transpose, and that will be Adj A.

Therefore, we will be able to get the inverse of matrix A using

[tex]A^{-1}[/tex] =Adj A|A|

and hence We then substitute all the obtained values of [tex]A^{-1}[/tex] and B in the main formula and do necessary calculations to get the value of x, y and z accordingly.

X+2y-3z=−26

-5x−3y+5z=23

Answer:

  x = 155°

Step-by-step explanation:

Given hexagon ABCDEF, you want to find the measure of interior angle E. Angles at vertices A, B, C, D, and F are specified.

The sum of the interior angles of an n-sided polygon is ...

  angle sum = (n -2)180°

For the 6-sided polygon given, the sum of interior angles is ...

  (6-2)180° = 720°

The interior angle at vertex B is 360° -80° = 280°.

The interior angle at vertex D is 180° -115° = 65°.

Then the sum of interior angles is ...

  A +B +C +D +E +F = 720°

  85° +280° +30° +65° +x +105° = 720° . . . . . substitute known values

  565° +x = 720° . . . . . . . collect terms

  x = 155° . . . . . . . . . . subtract 565°

Additional comment

The angles in the attached figure are drawn to scale.

An alternate solution might draw segment CX through vertex B so that the figure containing angle x has no reflex interior angles. Then the interior angles of pentagon ABXEF will total 540°. Known angles in that figure are A=85°, B=100°, X=95°, F=105°. Then E=x=540° -385° = 155°.

We took this approach initially, to verify that the angle sum of the given hexagon remained 720° even with the reflex interior angle at B.

Answer:

4.69 x 10⁵

Step-by-step explanation:

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 469,000

New Number: 4.69000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 4 . 6 9 0 0 0

Decimal Count: 1 2 3 4 5

There are 5 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 4.69 (Please notice any zeroes on the end have been removed)

b = 5

Now the whole thing:

4.69 x 10⁵

Step 4

Check your work:

105 = 100,000 x 4.69 = 469,000

Answer:   [tex]4.61 \times 10^5[/tex]

Reason:

The original number is 461,000 or 461000

Place a decimal point between the first two nonzero values. Erase the zeros and we get 4.61

To get back to 461000, we need to move the decimal point 5 spaces to the right. This is the exponent for the [tex]10^5[/tex] portion.

So [tex]461,000 = 4.61 \times 10^5[/tex]

[tex] \longrightarrow \: - 4 + \frac{x + 4}{3} - 2 = 2(x + 1) \\ \longrightarrow \: { -4} + \frac{x}{3} + \frac{4}{3} - {2} = 2x + 2 \\ \longrightarrow \: { - 4}+ \frac{4}{3} - {2} - 2 = 2x - \frac{x}{3} \\ \longrightarrow \: -4 - 2 - 2 + \frac{4}{3} = 2x - \frac{x}{3} \\ \longrightarrow \: - 8 + \frac{4}{3} = 2x - \frac{x}{3} \\ \longrightarrow \: \frac{ - 20}{3} = \frac{5}{3} x \\ \longrightarrow \:\frac{ - 20}{3} \times \:3\: = 5x \\ \longrightarrow \:-20 = 5x\\\longrightarrow \:\frac{-20}{5} = x \\\longrightarrow \:x = - 4[/tex]
