Answer:

Center: (9,3)

Radius: 9 units

Step-by-step explanation:

[tex]x^{2} -y^{2} -18x-6y+9=0[/tex]

[tex]x^{2} -18x+81+y^{2} -6y+9=-9+81+9[/tex]

[tex](x-9)^{2} +(y-3)^{2} =81[/tex]

Center: (9,3)

The new coordinate of the image after the reflection in the x-axis is [tex]P'(3, 4)[/tex].

What is reflection?

Reflection is a type of rigid geometrical transformation that maintains the object's size and shape, unlike other transformations such as dilation, which changes the size of the shape, reflection results in congruent images.

What is the rule for the reflection in the x-axis?

The rule for the reflection over the x axis is "if the point (x, y) reflected in axis the it becomes (x, -y).

According to the given question.

We have a coordinates of the image of P(3, -4).

So, when the coordinates of the image is reflected in the x-axis then the x coordinate remains same but the y coordinate changes its sign from negative to positive and we get the new coordinate of the image that is [tex]P'(3, 4).[/tex]

Hence, the new coordinate of the image after the reflection in the x-axis is [tex]P'(3, 4)[/tex].

Can someone explain this to me thank you

Answers

Answer: x = 16.9

Concept:

Here, we need to know the idea of basic trigonometry.

Sine = Opposite / Hypotenues = O / H

Cosine = Adjacent / Hypotenues = A / H

Tangent = Opposite / Adjacent = O / A

Solve:

Angle θ = 50°

Opposite = x

Hypotenues = 22

Given formula

Sine = Opposite / Hypotenues

Substitute the value into the formula

sin (50) = x / 22

Multiply 22 on both sides

sin (50) × 22 = x/22 × 22

x = 22 sin (50)

x = 16.9

Answer:

negative

Step-by-step explanation:

Let,

x1 = 0

x2 = 1

y1 = 50

y2 = 44

Formula : -

Slope = ( y2 - y1 ) / ( x2 - x1 )

Slope

= ( 44 - 50 ) / ( 1 - 0 )

= - 6 / 1

= - 6

- 6 is a negative number.

So, the slope is negative.

1) Se o 5o e o 9-o termos de uma PA são, respectivamente, 40 e 68, então a razão r da progressão é: a) r = 6 b) r = 7 c) r = 9 d) r = 11 e) r = 12 2) Inserindo-se 6 números entre 72 e 107, de modo que a sequência (72, a2, a3, a4, a5, a6, a7 ,107) seja uma progressão aritmética, tem-se a3 igual a: a) 78 b) 79 c) 80 d) 81 e) 82

Answers

Answer:

1) b) r = 7

2) e) 82

Step-by-step explanation:

Progressão aritmética:

Em uma progressão aritmética, a diferença entre termos consecutivos é sempre a mesma, chamada de razão.

O n-ésimo termo de uma PA é dado por, tomando o primeiro termo como referência:

[tex]a_n = a_1 + (n-1)r[/tex]

Tomando o m-ésimo termo como referência, tem-se que:

[tex]a_n = a_m + (n-m)r[/tex]

1) Se o 5o e o 9-o termos de uma PA são, respectivamente, 40 e 68, então a razão r da progressão é:

[tex]a_5 = 40, a_9 = 68[/tex]. Então:

[tex]a_n = a_m + (n-m)r[/tex]

[tex]68 = 40 + 4r[/tex]

[tex]4r = 28[/tex]

[tex]r = \frac{28}{4} = 7[/tex]

Então a resposta correta é dada pela alternativa b.

2) Inserindo-se 6 números entre 72 e 107, de modo que a sequência (72, a2, a3, a4, a5, a6, a7 ,107) seja uma progressão aritmética, tem-se a3 igual a:

O primeiro termo é [tex]a_1 = 72[/tex] e o oitavo termo é [tex]a_8 = 107[/tex]. Com isso, é possível encontrar a razão.

[tex]a_n = a_1 + (n-1)r[/tex]

[tex]107 = 72 + 7r[/tex]

[tex]7r = 35[/tex]

[tex]r = \frac{35}{7} = 5[/tex]

Então, o terceiro termo é:

[tex]a_3 = a_1 + 2r = 72 + 2(5) = 82[/tex]

Logo, a resposta correta é dada pela alternativa e.

A 1-pound bag of sunflower seeds provides 96 grams of protein, There
are 58.5 grams of protein in a 6.5-ounce bag of pumpkin seeds. Which
type of seed has more grams of protein per ounce? How many more
grams of protein are there in 24 ounces of the higher-protein seeds?

Answers

Answer:

Pumpkin seed has more grams of protein per ounce

216 grams of protein

Step-by-step explanation:

1 pound = 16 ounce

16 ounce of sunflower seeds = 96 grams of protein

6.5 ounce of pumpkin seeds = 58.5 grams of protein

Which type of seed has more grams of protein per ounce?

Sunflower seeds:

Protein per ounce = 96 grams / 16 ounce

= 6 grams of protein per ounce

Pumpkin seeds:

Protein per ounce = 58.5 grams / 6.5 ounce

= 9 grams of protein per ounce

Therefore,

Pumpkin seed has more grams of protein per ounce

How many more grams of protein are there in 24 ounces of the higher-protein seeds?

Quantity of protein = 24 ounces ×

9 grams of protein per ounce

= 216 grams of protein

Answers

Answer:

A

Step-by-step explanation:

The x value of the center = 0

The y value of the center = 220/2 + 11 = 110 + 11 = 121

so the center is at (0,121)

The radius is 220/2 = 110

The equation of the Ferris Wheel is

x^2 + (y - 121)^2 = 110^2

x^2 + (y - 121)^2 = 12100

A student buys 5-cent, 10-cent, and 15-cent stamps, with a total value of $6.70. If the
number of 5-cent stamps is 2 more than the number of 10-cent stamps, while the
number of 15-cent stamps is 5 more than one half the number of 10-cent stamps, how
many 15-cent stamps did the student obtain?

Answers

The value of the 10 cent stamps is, as you said, , the value of the 5 cent stamps is and the value of the 15 cent stamps is 15(0.5n + 5). These three values add up to the total value of the stamps, namely $6.70.

10n + 5(n+2) + 15 (1/2n + 5) = 6.70

10n +5n + 10 + 15/2n + 75 =670

10n + 5n + 15/2n =585

20n + 10n + 15n = 1170

45n = 1170
