Answer:

The values of [tex]r_{2}[/tex] and [tex]\alpha_{2}[/tex] are 2 and 150º.

Step-by-step explanation:

The complete statement is:

Find [tex]\alpha_{2}[/tex] and [tex]r_{2}[/tex] such that  [tex]\sin \theta - \sqrt{3}\cdot \cos \theta = r_{2}\cdot \cos (\theta - \alpha_{2})[/tex].

We proceed to use the following trigonometric identity:

[tex]\cos (\theta - \alpha_{2}) = \cos \theta \cdot \cos \alpha_{2} +\sin \theta \cdot \sin \alpha_{2}[/tex] (1)

[tex]\sin \theta -\sqrt{3}\cdot \cos \theta = r_{2}\cdot \cos \theta \cdot \cos \alpha_{2}+r_{2}\cdot \sin \theta \cdot \sin \alpha_{2}[/tex]

By direct comparison we derive these expressions:

[tex]r_{2}\cdot \sin \alpha_{2} = 1[/tex] (2)

[tex]r_{2}\cdot \cos \alpha_{2} = -\sqrt{3}[/tex] (3)

By dividing (2) by (3), we have the following formula:

[tex]\tan \alpha_{2} = -\frac{1}{\sqrt{3}}[/tex]

[tex]\tan \alpha_{2} = -\frac{\sqrt{3}}{3}[/tex]

The tangent function is negative at second and fourth quadrants. That is:

[tex]\alpha_{2} = \tan^{-1} \left(-\frac{\sqrt{3}}{3} \right)[/tex]

There are at least two solutions:

[tex]\alpha_{2,1} = 150^{\circ}[/tex], [tex]\alpha_{2,2} = 330^{\circ}[/tex]

And the value of [tex]r_{2}[/tex]:

[tex]r_{2}^{2}\cdot \sin^{2}\alpha_{2} + r_{2}^{2}\cdot \cos^{2}\alpha_{2} = 4[/tex]

[tex]r_{2}^{2} = 4[/tex]

[tex]r_{2} = 2[/tex]

The values of [tex]r_{2}[/tex] and [tex]\alpha_{2}[/tex] are 2 and 150º.

Determine the geometric mean of 45 and 15​

Answers

The answer to “determine the geometric mean to 45 and 15” is 60

The solution is, The geometric mean of 45 and 15​ is 25.98.

What is geometric mean?

The Geometric Mean (GM) in mathematics is the average value or mean that, by calculating the product of the values of the set of numbers, denotes the central tendency of the numbers. In essence, we multiply the numbers together and calculate their nth root, where n is the total number of data values.

here, we have,

We are given two numbers as 45 and 15​.

Formula for geometric mean is

G.M = √x₁ × ... × xₐ  

So, using this we get

⇒G.M = √45 × 15

⇒G.M = √675

⇒G.M = 25.98

Hence, the geometric mean of 45 and 15​ is 25.98.

What is the Area of a Rectangle?

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the cost to buy rectangular window be represented as A

Now , the value of A is

The length of the rectangular window be L = 10 feet

The width of the rectangular window be W = 13 feet

Let the cost per square foot be c = $ 7.02

Area of Rectangle = Length x Width

Substituting the values in the equation , we get

Area of rectangular window = 10 x 13 = 130 feet²

The cost to buy the rectangular window A = 130 x cost per square foot

Substituting the values in the equation , we get

The cost to buy the rectangular window A = 130 x 7.02

The cost to buy the rectangular window A = $ 912.60

Hence , the cost to buy the window is $ 912.60

Solve for x. Enter the solutions from least to greatest.
(x+7)^2 −49=0


Help plz

Answers

Answer:

x=0

Step-by-step explanation:

We can first add 49 to both sides to get (x+7)^2=49

We can then take the square root of both sides and get x+7=7

Subtract 7 to both sides and you get x=0

Answer:

[tex]x=-14\text{ and } x=0[/tex]

Step-by-step explanation:

We are given:

[tex](x+7)^2-49=0[/tex]

And we want to solve for x.

First, we can add 49 to both sides:

[tex](x+7)^2=49[/tex]

Now, we can take the square root of both sides. Since we are taking an even root, we will need plus-minus. Hence:

[tex]x+7=\pm\sqrt{49}[/tex]

Evaluate:

[tex]x+7=\pm7[/tex]

Subtract 7 from both sides:

[tex]x=-7\pm7[/tex]

So, we have two solutions:

[tex]x=-7+7\text{ and } x=-7-7[/tex]

Evaluate:

[tex]x=0\text{ and } x=-14[/tex]

So, from least to greatest, our solutions are:

[tex]x=-14\text{ and } x=0[/tex]

Second you have to figure out how many tax returns you have to make by dividing 6300 by 14 to get 450

Here are the first four terms of a quadratic sequence.
The nth term of this sequence is an² + bn + c.
1, 11, 27 and 49
Find the values of a, b and c.

Answers

Answer:

a = 3, b = 1, c = - 3

Step-by-step explanation:

Substitute n = 1, 2, 3 into the n th term

a + b + c = 1 → (1)

4a + 2b + c = 11 → (2)

9a + 3b + c = 27 → (3)

Subtract (1) from (2) term by term to eliminate c

Subtract (2) from (3) term by term to eliminate c

3a + b = 10 → (4)

5a + b = 16 → (5)

Subtract (4) from (5) term by term to eliminate b

2a = 6 ( divide both sides by 2 )

a = 3

Substitute a = 3 into (4) and evaluate for b

3(3) + b = 10

9 + b = 10 ( subtract 9 from both sides )

b = 1

Substitute a = 3, b = 1 into (1) and evaluate for c

3 + 1 + c = 1

4 + c = 1 ( subtract 4 from both sides )

c = - 3

Then a = 3, b = 1 and c = - 3

The measure of a, b and c is  3, 1 and - 3 respectively.

What is a quadratic sequence?

A quadratic sequence is a sequence whose nth term is given by the general formula -

A{n} = an² + bn + c.

Given are the 4 terms of the quadratic sequence as 1, 11, 27 and 49.

Now, we can the following equations as -

A{1} = a + b + c = 1

a + b + c = 1

c = 1 - a - b              ........ Eq[1]

A{2} = 4a + 2b + c = 11

4a + 2b + c = 11

c = 11 - 4a - 2b           ........ Eq[2]

A{3} = 9a + 3b + c = 27

9a + 3b + c = 27

c = 27 - 9a - 3b               ........ Eq[3]

A{4} = 16a + 4b + c = 49

16a + 4b + c = 49

c = 49 - 16a - 4b             ........ Eq[4]

Equate Eq[1] and Eq[2] -

1 - a - b  =  11 - 4a - 2b  

1 - 11 = - 4a - 2b + a + b

- 10 = - 3a - b

3a + b = 10                ........... Eq[5]

Equate Eq[3] and Eq[4] -

27 - 9a - 3b = 49 - 16a - 4b  

- 9a - 3b + 16a + 4b = 49 - 27

7a + b = 22          .......... Eq[6]

We can write -

7a + 10 - 3a = 22

4a + 10 = 22

4a = 12

a = 3

and

b = 10 - 3a

b = 10 - 9

b = 1

At last -

c = 1 - a - b

c = 1 - 3 - 1

c = - 3

Therefore, the measure of a, b and c is  3, 1 and - 3 respectively.

The missing angle I believe is 25%.

Step-by-step explanation:

180-130=50

Divide 50 by 2 and it equals 25. 25 degrees for each angles.

Answer:25

Step-by-step explanation:

alright so the triangle theorem states that all of the angles of a triangle add up to 180. we already of 130 so we take away 130 from 180 to get 50. If you see the two little lines on the triangles sides opposite of the two angles that we are missing then you can tell by those lines that the angles opposite of them are equal to each other. So you divide 2 from 50 to get 25 which is the value of x. Hope you understand this (:

We can turn 1/4 into all of the first three fractions by multiplying it by some version of 1, but we can't do the same for 3/9: trying to multiply 1/4 by 3/3 will get us a different fraction: 3/12. Additionally, 3/9 in lowest form is 1/3, and 1/3 is clearly not equal to 1/4.

Answer:

for ac I got 11

ab i got 14

I'm not quite sure tho

but you could use SOH CAH TOA to find ab then use Pythagoras theorem to find AB

Answer:

AB = 11.6 inches

AC = 7.3 inches

m∠B = 39°

Step-by-step explanation:

To calculate side AB (c) put b (9 inches) over the sine of β (51°).

c = 9/sin(51)

The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle (the hypotenuse). This would be about 0.777.

c = 9/0.777

I recommend using a fraction here. 0.777 becomes 777/1000. Find the reciprocal (1000/777). Switch the sign to multiplication.

c = 9/1 * 1000/777

Cross cancel if needed.

c = 3/1 * 1000/259

Now multiply.

c = 3000/259

Divide 3000 by 259.

c ≈ 11.5830116 inches ≈ 11.6 inches

Now we know AB. To find AC, find the square root of AB² - BC².

AC = √(11.6² - 9²)

Square both 11.6 and 9.

AC = √(134.56 - 81)

Add 134.56 and 81 to get 53.56

AC = √53.56

Find the square root of 53.56

AC ≈ 7.31846979 ≈ 7.3 inches.

Finding the measure of angle B is comparatively simple. Subtract 51 from 90 to get 39° for angle B.
