11. Which of the following statements contains a quotient?
O A.76 = 42
OB. 42 - 6 = 7
O C. 7 + 6 = 13
OD.7 - 6 = 1

Answer:

x=139

Step-by-step explanation:

x and 139 are alternate exterior angles. Since a transversal passes through lines m and n, They are congruent using the alt. interior angle theorem.

so x=139

Answer:

[tex]\frac{4}{3 - i} = \frac{6}{5} + \frac{2}{5}i[/tex]

Step-by-step explanation:

Given

[tex]\frac{4}{3 - i}[/tex]

See attachment for question

Required

Correct Ramon's error

Start by rationalizing the expression:

[tex]\frac{4}{3 - i} = \frac{4}{3 - i}*\frac{3 + i}{3 + i}[/tex]

[tex]\frac{4}{3 - i} = \frac{4(3 + i)}{(3 - i)(3 + i)}[/tex]

Expand

[tex]\frac{4}{3 - i} = \frac{12 + 4i}{3^2 - i^2}[/tex]

[tex]\frac{4}{3 - i} = \frac{12 + 4i}{9 - i^2}[/tex]

In complex numbers:

[tex]i^2 = -1[/tex]

So:

[tex]\frac{4}{3 - i} = \frac{12 + 4i}{9 - (-1)}[/tex]

[tex]\frac{4}{3 - i} = \frac{12 + 4i}{9 +1}[/tex]

[tex]\frac{4}{3 - i} = \frac{12 + 4i}{10}[/tex]

Split fraction

[tex]\frac{4}{3 - i} = \frac{12}{10} + \frac{4i}{10}[/tex]

[tex]\frac{4}{3 - i} = \frac{6}{5} + \frac{2}{5}i[/tex]

1. I don't know how to solve that sorry :(

2. B. It is a diameter

3. 30° = q

4. I don't know sorry :(

Step-by-step explanation:

1. I don't know how to solve that sorry :(

-----------------------------------------------------------

2. B. It is a diameter

------------------------------------

3. All triangles = 180°

180° = 60° + 90° + q

180° = 150° + q

180° - 150° = 150° - 150° + q

30° = q

180° = 60° + 90° + 30°

180° = 150° + 30°

180° = 180°

------------------------------------------

4. I don't know sorry :(

Answer:

2.899

Step-by-step explanation:

Given that:

[tex]f' (x) =3 tan ^{-1} (x^2 -3x +2)[/tex]

[tex]\text{applying integration on both sides with respect to x}[/tex]

[tex]\int \limits ^{3}_{1}} f'(x) \ dx = \int ^3_1 3tan ^{-1} (x^2 -3x+2) \ dx[/tex]

[tex]f(3)-f(1)= 3 \int ^3_1 3tan ^{-1} (x^2 -3x+2) \ dx[/tex]

[tex]f(3) = \dfrac{\pi}{2}+3\int^{3}_{1} tan^{-1} (x^2 -3x+2)dx ---(1)[/tex]

[tex]\text{consider } \ \ 3\int^{3}_{1} tan^{-1} (x^2 -3x+2)dx[/tex]

[tex]h = \dfrac{b-a}{n}[/tex]

[tex]where; n = 10 , a =1, b= 3[/tex]

[tex]h = \dfrac{3-1}{10}[/tex]

[tex]h = \dfrac{2}{10}[/tex]

[tex]h = 0.2[/tex]

[tex]\text{The value of x and corresponding } y = 3tan^{-1}(x^2-3x+2) \ are:[/tex]

x     1      1.2      1.4      1.6      1.8      2      2.2      2.4      2.6      2.8      3

y   f(0)  f(1.2)   f(1.4)   f(1.6)   f(1.8)   f(2.0)  f(2.2)  f(2.4)  f(2.6)  f(2.8)   f(3)

By simpson's rule:

[tex]\int \limits ^3_1 \ 3 tan^{-1} (x^2-3x+2) dx \simeq \dfrac{h}{3}(y_o+y_{10}) +4(y_1+y_3+y_5+y_7+y_9)+2(y_2+y_4+y_6+y_8)][/tex]

[tex]=\dfrac{0.2}{3}\Big[(0+3.3214)+(-1.9039+2.8265+1.4133+6.1259+11.5657)+2(-1.4133-0.9519+1.4133+4.5899)\Big][/tex]

[tex]= 1.32804[/tex]

[tex]\text{From}; f(3) = \dfrac{\pi}{2}+1.32804 \\ \\ f(3) = 2.89883633 \\ \\ \mathbf{f(3) \simeq 2.899}[/tex]

Trapezoidal rule is used to evaluate the area of the curve by using various strips of equal width which is in the form of trapezoids. The value of [tex]f(3)[/tex] is 2.8989.

Given information

In the given problem [tex]f[/tex] is the function such that,

[tex]f(1)=\dfrac{\pi}{2} \\[/tex]

The differentiated function is,

[tex]f'(x)=3\tan^-(x^2-3x+2)[/tex]

Integrate the above equation with respect to the x,

[tex]\int\limits^3_1 {f'(x)} \, dx =\int\limits^3_1 {3\tan^-(x^2-3x+2)} \, dx\\f(3)-f(1) =\int\limits^3_1 {3\tan^-(x^2-3x+2)} \, dx\\f(3) =3\int\limits^3_1 {\tan^-(x^2-3x+2)} \, dx +f(1)\\f(3) =3\int\limits^3_1 {\tan^-(x^2-3x+2)} \, dx +\dfrac{\pi}{2}[/tex]           .........1

Let the above equation is the equation number 1.

Let the integrated function,

[tex]y=3\int\limits^3_1 {\tan^-(x^2-3x+2)} \, dx[/tex]

Solve the above equation using the trapezoidal rule.

Trapezoidal rule is used to evaluate the area of the curve by using various strips of equal width which is in the form of trapezoids.

In the given problem,

[tex]h=\dfrac{b-a}{n}[/tex]

Use this formula for the integrated function,

[tex]h=\dfrac{3-1}{10}\\h=0.2[/tex]

Use the Simpson formula to solve the above equation,

[tex]=3\int\limits^3_1 {\tan^-(x^2-3x+2)} \, dx[/tex]

[tex]=\dfrac{h}{3} (y_0+y_{10})+4(y_1+y_3+y_{5}+y_7+y_{9})+2(y_2+y_{4}+y_6+y_{8})[/tex]

Find the value of y by putting the values in the given formula. Thus,

[tex]=\dfrac{0.2}{3} (0+3.3214)+4(-1.9039+2.8266+1.4133+6.1259+11.5657)+2(-1.4133-0.9519+1.4133+4.5899)\\=1.32804[/tex]

Put this value in equation 1,

[tex]f(3) =1.30824 +\dfrac{\pi}{2}\\f(3)=2.8989[/tex]

Thus the value of [tex]f(3)[/tex] is 2.8989.

Answer:

  x ≈ 24.91

Step-by-step explanation:

It is helpful to remember the mnemonic SOH CAH TOA. It is intended to remind you that ...

  Sin = Opposite/Hypotenuse

You observe that the values are given in the figure for an acute angle in a right triangle, the hypotenuse, and the side opposite the angle. That is why you are interested in the sine relation.

  sin(49°) = x/33

  x = 33·sin(49°) ≈ 24.905

The length of side x is about 24.91 units.

Answer:

10 full servings and [tex]\frac{1}{4}[/tex] cups leftover

Step-by-step explanation:

Our container has a total of 20 and a half cups. And each full serving is 2 cups.

So, we divide [tex]\frac{20\frac{1}{2} }{2}[/tex].

To do this manually, we convert the numerator into an improper fraction: [tex]\frac{\frac{41}{2} }{2}[/tex].

Now, we multiply the denominators: [tex]\frac{41}{4}[/tex].

This will give us [tex]10\frac{1}{4}[/tex] servings. So we only have 10 full servings.

There are [tex]\frac{1}{4}[/tex] cups leftover.

Answer:

Step-by-step explanation:

To find the slope you need to follow the formula shown below.

Slope (m) = ΔY/ΔX

Now solve

ΔY = 6 – 0 = 6

ΔX = 2 – 0 = 2

Write as a fraction

6/2

Convert to a number

6/2 = 3

And you have your slope. Now you just have to plot the points on the graph. As I said before, you can use any two points from the table.

y = -3

Step-by-step explanation:

The given line is a horizontal line thru -5 on the y-axis.

Your line is parallel to y = -5, hence is also a horizontal line and passes thru (2, -3).  Since -3 is the y-coordinate of that point, y = -3 is the equation of the line you are looking for.

The area of the triangle ABC is 34.2 square centimeters

The complete question is in the image

Start by calculating the semi-perimeter using:

s = 0.5 * (a + b + c)

This gives

s = 0.5 * (9 + 10 + 8)

Evaluate

s = 13.5

The area is then calculated as:

[tex]A = \sqrt{s * (s - a) * (s - b) * (s - c)[/tex]

This gives

[tex]A = \sqrt{13.5 * (13.5 - 9) * (13.5 - 10) * (13.5 - 8)[/tex]

Evaluate

A = 34.2

Hence, the area of the triangle ABC is 34.2 square centimeters
