What is the length (magnitude) of the vector (-3,2)?
O A. Sqrt 13
OB. Sqrt 2
O c. 0
O D. 3

Answer:

  131.3°, 48.7°

Step-by-step explanation:

Let x represent the larger angle. Then x-82.6 is the smaller one. Their sum is ...

  x +(x -82.6) = 180

  2x = 262.6

  x = 131.3

  x -82.6 = 48.7

The two angle measures are 48.7° and 131.3°.

Answer:

46.2%

Step-by-step explanation:

6/13 x 100% = 46.1538461538% (rounded to the nearest tenth: 46.2%)

Answer:

Experimental Statistical Study

Step-by-step explanation:

Of the three types of statistical study, the one used by the researcher in this question is the experimental statistical study and the reason is as follows:

From the question, a study was conducted on a total of 4 high schools; these high schools were further divided into 2 pairs.

Each pair were subjected to or experimented with different method of teachings. At the end of the semester, the average were compared.

This implies that both pairs were experimented based on different teaching methods and the result of the methods were measured in order to determine which of the methods is better.

This type of study is experimental

Answer:

Experiment ; No, because the schools could be very different, meaning the randomization won't smooth out other effects.

Answer:Los contratos de opciones se pueden tasar utilizando modelos matemáticos como los modelos de precios Black-Scholes o Binomial. El precio de una opción se compone principalmente de dos partes distintas: su valor intrínseco y su valor temporal. ... El valor temporal se basa en la volatilidad esperada del activo subyacente y el tiempo hasta el vencimiento de la opción.

Step-by-step explanation:

Answer:

54 degrees. The triangle is isosceles, so 180-72= 108.

108/2=54

The solution is,  m KJL=54 degrees.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

from the given figure, we get,

The triangle is isosceles,

so 180-72= 108.

and, we know,

∠J=∠L

So,

108/2=54

Hence, The solution is,  m KJL=54 degrees.

Answer:

The slope of the line is [tex]-\frac{2}{3}[/tex]

Step-by-step explanation:

Slope:

When we have two points on a line, the slope is given by the change in y divided by the change in x.

Two points on a line are M(4,5) and N(-2,9).

Change in y: 9 - 5 = 4

Change in x: -2 - 4 = -6

The slope is:

[tex]m = \frac{4}{-6} = -\frac{2}{3}[/tex]

The slope of the line is [tex]-\frac{2}{3}[/tex]

Answer:

11 + c

Explanation:

In the parenthesis, 7 + c cannot be simplified, so there is no need for them. Now we have 7 + c + 4. Only 7 and 4 can be added. 7 + 4 = 11. The answer is 11 + c.

Answer:

c+11

Hi there! Your answer is -1/9

Please see an explanation for a better and clear understanding to your problem.

Any questions about my answer and explanation can be asked through comments!:)

Step-by-step explanation:

[tex] \large \boxed{ m = \frac{y_2-y_1}{x_2-x_1} }[/tex]

The formula above is slope formula. We will be using this to find a slope of a line.

From the graph, there are two points which are (4,0) and (-5,1).

You can either let (4,0) = (x1, y1) or (x2, y2) but I will be letting (-5,1) =(x2, y2)

Substitute the coordinate points in.

[tex] \large{m = \frac{1 - 0}{ - 5 - 4} } \\ \large{m = \frac{1}{ - 9} } \\ \large{m = - \frac{1}{9} }[/tex]

Hence, the slope is - 1/9. If you are curious where m-term comes from, it comes from y = mx+b where m = slope and b = y-intercept.

Answer:

x = 12

Step-by-step explanation:

180° = (3x - 6) + (8x + 4) + 50°  because all interior angles of a triangle add up to 180°

180° = 11x +48°

11x = 132°

x = 12

Ik its ridoculas so I looked it up believing myself

Answer is:

a= 90-70

=20

Answer:

The missing angle is 20°

Step-by-step explanation:

The square by the vertex indicates that this is a right angle. A right angle measures 90°. So what you can do is subtract the 70° from the 90°, to get 20°.

Answer:

25 miles

Step-by-step explanation:

4 days is 10 miles, 8 days is 20 miles. In order to find two days, divide the days and miles in half, leaving you with 2 days and 5 miles left. Therefore, 10 days is 25 miles. I hope this helped!

Answer:

The Slope is 0, the y-intercept is -5

Step-by-step explanation

Remember the formula

y = mx + b

m = slope

b = y-intercept

In this situation

y = 0x - 5

m = 0

b = -5
