These parallels gives us certain pair of angles which are congruent.

The given angle 63° is congruent with its corresponding angles. The image attached shows all corresponding angles that are equal to 63° (red angles).

Basically,

[tex]x+63=180[/tex] and [tex]k+63=180[/tex], by suplementary angles and straight angle definition.

Then, solving for [tex]x[/tex] and [tex]k[/tex], we have

[tex]x=180-63\\x=117\°[/tex]

[tex]k=180-63\\k=117\°[/tex]

Therefore, both angles are equal to 117°.

The measure of each angle are:

Given:

AB || CD

EF || GH

As, the lines are parallel and parallel line have following properties

So, <m = 63 {Corresponding angle}

Now, <m + <n = 180 {Linear pair}

63 + <n =180

<n =180 - 63

<n = 117

and, <k = 63 {Vertical opposite angle}

and, <k = <x = 63  {Corresponding angle}

and, <w = <x = 63  (alternate Interior angle}

and, <p = <w = 63 {Vertical opposite angle}

Answer:

axis of symmetry is [tex]x=\frac{-9}{2}[/tex].

The ordered pair of the vertex is [tex](\frac{-9}{2},\frac{-145}{4})[/tex].

Step-by-step explanation:

Your function is a quadratic.

Compare [tex]x^2+9x-16[/tex] to [tex]ax^2+bx+c[/tex].

You should see that [tex]a=1,b=9,c=-16[/tex].

The x-coordinate of the vertex or the axis of symmetry since the axis symmetry goes through the vertex can be found by computing [tex]\frac{-b}{2a}[/tex].

So here we go!

The axis of symmetry is [tex]x=\frac{-9}{2(1)}=\frac{-9}{2}[/tex].

When you write your axis of symmetry be sure to write it as an equation.

That is the axis of symmetry is [tex]x=\frac{-9}{2}[/tex].

Now that was also the x-coordinate of your vertex.  To find the corresponding y-coordinate of the vertex, plug your value for [tex]x[/tex] into

[tex]y=x^2+9x-16[/tex].

[tex]y=(\frac{-9}{2})^2+9(\frac{-9}{2})-16[/tex]

Put into calculator:

[tex]y=\frac{-145}{4}[/tex] when [tex]x=\frac{-9}{2}[/tex]

The ordered pair of the vertex is [tex](\frac{-9}{2},\frac{-145}{4})[/tex].

Answer:

Vertex: [tex](h,k)\rightarrow(-4.5,-36.25)[/tex]

Axis of symmetry: [tex]x=-4.5[/tex]

Step-by-step explanation:

First I'll find the axis of symmetry. This formula lets us find the a.o.s: [tex]x=\frac{-b}{2a}[/tex].

In [tex]x^2+9x-16[/tex], the values of a, b, and c are:

We only need a and b to find the axis of symmetry. Substitute these values into the formula.

Simplify this fraction.

The axis of symmetry of this quadratic function is x = -4.5.

Now to find the vertex, we have to take into account that this quadratic is in standard form, making it a little harder. We have to convert this function into vertex form.

Start by changing f(x) to 'y' and adding 16 to both sides.

Use the completing the square formula: [tex](\frac{b}{2} )^2[/tex]

Keep the balance by adding 20.25 on the left side and adding it on the right side of the equation.

Combine like terms.

Factor the right side of the equation. Ask yourself, "What two numbers multiply to 20.25 (c) and add up to 9 (b)?" These two numbers are 4.5 and 4.5. Rewrite the right side with factors.

Isolate y by subtracting 36.25 from both sides of the equation.

Now this quadratic function is in vertex form, making it super simple to find the vertex using [tex](h, k)[/tex].

Vertex form of a quadratic is:

Compare [tex]y=(x+4.5)^2-36.25[/tex] with the original vertex form and find where h and k are. Those are the x (h) and y (k) values of the vertex.

Since the original vertex form has x - h, the h value in [tex]y=(x+4.5)^2-36.25[/tex] would be a negative since two negatives make a positive. The k value would stay "normal"---negative would mean it is a negative and positive would mean it is a positive number.

Therefore the h value is -4.5, and the k value is -36.25.

The ordered pair of the vertex is [tex](-4.5, -36.25)[/tex].

Answer:

The approximate value of arc cos(0.87) is 29.54°

Step-by-step explanation:

we know that

The arc cosine of x is defined as the inverse cosine function of x

so

if y=cos(x)

then

arc cos (y)=x

In this problem we have

y=0.67

so

x=arc cos(0.87)

using a calculator

x=29.54°

So, the approximate value of arccos(0.67) is about 0.84108 radians.

To approximate arccos(0.67) using a calculator, we find it to be approximately 0.84108 radians. This value represents the angle whose cosine is 0.67. Arccos, or inverse cosine, returns the angle in radians between 0 and π (approximately 3.14159) whose cosine is the input value. In this case, 0.67 is the cosine of the angle 0.84108 radians. This angle is commonly used in trigonometric calculations, such as determining the angle of a vector or solving geometric problems involving cosine functions.Let's use a calculator to find the approximate value of arccos(0.67).

Answer:

122.2 in^2.

Step-by-step explanation:

WE can divide a regular octagon into 8 triangles with height ( = the apotherm) = 6.5 and  base = 4.7.

The area of each triangle is 1/2 * 4.7 *6.5 so #the area of the octagon

= 8 * 1/2 * 4.7 * 6.5

= 122.2 in^2.

For this case we have by definition, that the area of an octagon is given by:

[tex]A = \frac {p * a} {2}[/tex]

Where:

p: perimeter

a: apothem

We have that the perimeter is given by the sum of the sides of the octagon:

[tex]p = 8 * 4.7 = 37.6 \ in\\a = 6.5 \ in[/tex]

Substituting:

[tex]A = \frac {37.6 * 6.5} {2} = 122.2[/tex]

So, the area of the octagon is[tex]122.2 \ in ^ 2[/tex]

39 meat patties

Step-by-step explanation:

Given,

The Big Burger recipe calls for 3 meat patties, 2 slices of cheese and 4 pickles,

That is, the ratio of meat patties, cheese and pickles in the recipe = 3 : 2 : 4

Let in a recipe,

Meat patties = 3x, Cheese = 2x, pickles = 4x

Where, x is a positive real number,

If there are 52 pickles,

⇒ 4x = 52 ⇒ x = 13

Hence, meat patties = 3 (13) = 39

Answer:

A 54

Step-by-step explanation:

RC = 126

WC = 72

RC = WC + RW

126 = 72+RW

Subtract 72 from each side

126-72 = 72-72+RW

54 = RW

Answer: First option

[tex]RW=54[/tex]

Step-by-step explanation:

Notice in the image that the distance from R to C is equal to 126.

Then we write:

[tex]RC = 126[/tex]

Also note that the distance between W and C is 72.

We know that:

[tex]RC=RW + WC[/tex]

In this case we want to find RW, so we solve the equation for RW

[tex]RC-WC=RW + WC-WC[/tex]

[tex]RC-WC=RW[/tex]

[tex]RW=RC-WC[/tex]

Now we substitute the values of RC and WC into the equation

[tex]RW=126-72[/tex]

[tex]RW=54[/tex]

[tex]\text{From the graph:}\\\\\text{the function is decreased}\to 0<a<1\\\\h<0\\\\k>0[/tex]

The correct answer is: Option: C

              C.  0<a<1

We are given a graph of a exponential function as:

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

We know that the function is a exponential decay function if: 0<a<1

and it represents a exponential growth function if: a>1

Hence, by looking at the graph we observe that the graph is continuously decreasing with increasing values of x.

This means that the graph is a graph of exponential decay function.

Hence, we get:   0<a<1

For    [tex]x^x > 500,000[/tex]  [tex]x=7[/tex]

For  [tex]x^{(-x)} > 500,000[/tex]  [tex]x=-7[/tex]

Step-by-step explanation:

We need to find the smallest positive whole number that satisfies the inequality:

[tex]x^x > 500,000[/tex]

We tested with x = 6

[tex]6^6=46,656\\\\46,656 > 500,000[/tex]

Inequality is not met because  [tex]46,656 < 500,000[/tex]

We test with the following integer x = 7

Then we have that:

[tex]7^7=823,543\\\\823,543 > 500,000[/tex]

Then the smallest positive integer that will make  [tex]x^x > 500,000[/tex]  is 7 because Inequality is met.

In the same way the largest negative integer that will make  [tex]x^{(-x)} >500000[/tex] is [tex]x=-7[/tex] Beacuse   [tex]7^{-(-7)}=823,543>500,000[/tex]

Answer:

Smallest positive integer value for [tex]x^x>500000[/tex] is,

x = 7,

Largest negative integer value for [tex]x^{-x}>500000[/tex] is,

x = -8

Step-by-step explanation:

If [tex]x^x>500000[/tex]

By graphing calculator,

[tex]x>6.83[/tex]

Thus, the smallest possible positive integer value of x is 7,

Now,

[tex]x^{-x}>500000[/tex]

Possible negative integer values of x are -6, -7 and -8,

If x = -6, -7, and -8,

[tex](-6)^{6}=46656[/tex]

[tex](-7)^{7}=-823543[/tex]

[tex](-8)^{8}=16777216[/tex]

[tex]\because 16777216 > 500000[/tex]

Thus, the largest negative integer value of the inequality [tex]x^{-x}>500000[/tex] is,

x = -8.

The circumcenter O, formed by the intersection of the perpendicular bisectors of sides AB and BC, is equidistant from all vertices, with OA = OB = OC. Here option B is correct.

In a triangle, the circumcenter is the point where the perpendicular bisectors of its sides intersect. In this case, the circumcenter O is formed by the intersection of the perpendicular bisector of side AB and the perpendicular bisector of side BC.

The circumcenter is equidistant from all three vertices, making OA, OB, and OC equal, and these distances represent the radius of the circumcircle.

This line not only bisects side AB but also intersects with the perpendicular bisector of side BC at the circumcenter O. The equality of OA, OB, and OC ensures that the circumcircle passes through all three vertices of the triangle, making it a significant point in the context of the triangle's geometry. Here option B is correct.

Step-by-step explanation:

Since triangle ADE is similar to triangle ABC

Angle ADE equals angle ADC

The angles of a triangle add to 180 degrees

<A + <ADE + <AED = 180

36 + 84+ <AED = 180

Combine like terms

120 + <AED = 180

Subtract 120 from each side

120-120 +<AED = 180-120

<AED = 60

Answer:

58°

Step-by-step explanation:

Since DE and BC are parallel, ADE will be equal to ABC.

So ADE is 84°.

And, the sum of the angles of a triangle is 180°. So AED will be equal to 180-(38 + 84),which is 58°

A = [tex]\frac{1}{2}[/tex] product of diagonals, that is

A = 0. 5 × MK × JL = 0.5 × 13 × 17 = 110.5

The area of the rhombus will be 110.5 square units.

The area of the rhombus can be calculated by half of the product of its two diagonals.

Here given,

JKLM is a rhombus.

JL=17

The diagonal MK and JL intersect each other by 90° at point O.

Now the rhombus is divided by 4 right-angled triangle,

Area of the rhombus will be 4 times of the right-angled triangle ΔMJO

Area of the rhombus= 4*Area of right-angled triangle ΔMJO

=4*(1/2)*MO*JO

= 4*(1/2)*(MK/2)(JL/2)

=(1/2)*MK*JL

=(1/2)*the product of its two diagonals

=(1/2)*13*17

=110.5 Square unit

3   -  m =  d.............(1)

and

(3.75 - m) / d = 2

3.75 - m = 2d....... (2)

Subtract (2) - (1):

[tex]+2=\dfrac{3.75-\mu}{\sigma}\\\\\Rightarrow\ \mu=3.75-2\sigma---(ii)[/tex]

From (i) and (ii) , we have

Good idea to review quadratic functions and the quadratic formula.

Quadratics have three coefficients:  ax² + bx + c, and the "discriminant" is defined as b²-4ac.  Please review these rules:

1) if the discriminant is +, the quadratic equation has two real, unequal roots.

2) if the disc. is 0, the equation has two real, equal root.

3) If the disc. is - , the equation has two complex roots.

Here a = 1, b  = -3 and c = 4.  Therefore the discriminant is (-3)²-4(1)(4), or

-7.  Rule 3) applies:  the equation has two complex roots, but no real ones.  Thus we know that the graph does not cross the x-axis.

Graphing the given quadratic, x² - 3x + 4, using a dashed "line," is helpful.  As you can see in the illustration of this graph, the graph neither touches nor crosses the x-axis.  Thus, y = x² - 3x + 4 is greater than 0 for all x.  The answer:  All real numbers.

Reflection is the correct answer

A reflection would be the single transformation required to map one congruent triangle onto the other in this scenario, with the line AD serving as the line of reflection.

The single transformation required to map one congruent triangle onto the other is a translation.

In the context of two congruent triangles, when point M is the midpoint of AD, the single transformation to map one triangle onto the other would be a reflection. Imagine the line segment AD as the mirror or line of reflection. Because M is the midpoint, both halves of the line segment would mirror each other exactly, corresponding to the two congruent triangles. This means the triangle on one side of the line AD can be reflected over the line AD to coincide exactly with the triangle on the other side.

BC = 10.3 miles ( rounded to the nearest tenth).

The distance from point B to point C is 10.3 mi (to the nearest tenth).

If we have a right angle triangle,
