Which angle corresponds to angle 6

If you mean to find 4 cos(2a), then recall the double angle identity for cosine:

cos(2x) = 2 cos²(x) - 1

so that

4 cos(2a) = 4 (2 cos²(x) - 1) = 4 (√3 - 1)

Answer:

2

Step-by-step explanation:

2 cubed is 8, then divided by 4 is 2

Answer:

The slope would be 2

Step-by-step explanation:

All you do is pick two order pairs: (2,6) and (4,10),  then you do y1 - y2, so 10-6 to get 4 then do x1 - x2, so 4 - 2 which is 2, then you divide 4 by 2 to get 2.

Answer:

D $26

Step-by-step explanation:

Given:

In ΔHIJ, h = 40 cm, ∠J=20° and ∠H=93°.

To find:

The length of j, to the nearest centimeter.

Solution:

According to Law of sine,

[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

In ΔHIJ, using law of sine, we get

[tex]\dfrac{j}{\sin J}=\dfrac{h}{\sin H}[/tex]

[tex]\dfrac{j}{\sin (20^\circ)}=\dfrac{40}{\sin (93^\circ)}}[/tex]

[tex]j=\dfrac{40\times \sin (20^\circ)}{\sin (93^\circ)}}[/tex]

On further simplification, we get

[tex]j=\dfrac{40\times 0.34202}{0.99863}[/tex]

[tex]j=\dfrac{13.6808}{0.99863}[/tex]

[tex]j=13.69958[/tex]

Approximate the value to the nearest centimeter.

[tex]j\approx 14[/tex]

Therefore, the length of j is 14 cm.

Answer:

The sample  size is  [tex]n =68[/tex]

Step-by-step explanation:

    The population proportion is  [tex]\^ p = 0.50[/tex]

     The margin of error is  [tex]E = 0.1[/tex]

From the question we are told the confidence level is  90% , hence the level of significance is    

      [tex]\alpha = (100 - 90 ) \%[/tex]

=>   [tex]\alpha = 0.10[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.645 [/tex]

Generally the sample size is mathematically represented as  

    [tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]

=>  [tex]n = [\frac{1.645 }{0.1} ]^2 * 0.50  (1 - 0.50 ) [/tex]

=>  [tex]n =68[/tex]

Answer:

I think 32% (Let me know if I am wrong)

Step-by-step explanation:

Answer:

C) 32%

Step-by-step explanation:

Brand A: 32 Diapers, $8.99: about 28 cents per diaper

Brand B: 50 Diapers, $12.49: about 24 cents per diaper

You divide the amount of diapers by the money.

For example, 32 diapers/$8.99 equals about 28 cents per diaper and 50 diapers/$12.49 equals about 24 cents per diaper.

Brand B is the better deal since you save about 4 cents more.

Answer:

the answer is 222

Answer:

222

Step-by-step explanation:

To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 600, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:

37/100 = X/600

X/600 = 37/100

X*600/600 = 37*600/100

X = 22200/100

X = 222

Answer:

2785,32

Step-By-Step:

30948*0.09

Answer:

2785.32

Step-by-step explanation:

solution,

9 % of 30948

= 9/100×30948

= 278532/100

= 2785.32

9%of 30948 is 2785.32

Answer:

1200

Step-by-step explanation:

1680/1050 = 1920/x

1680x = 2,016,000

x=1200

There are 1200 vertical pixels.

This is a ratio problem, which uses ratios to relate different items in the question. In a ratio problem, it's important to remember to

1) Write the items in the ratio as a fraction.

2) Make sure that you have the same items in the numerator and denominator.

The first step is to assign variables. Let x = vertical resolution of the 23" monitor.

Write the items in the ratio as a fraction.

[tex]\frac{horizontal}{vertical} = \frac{1680}{1050} = \frac{1920}{x}[/tex]

Solve the equation.

      Cross multiply:

[tex]1680*x = 1920 * 1050[/tex]

[tex]1680x=2016000[/tex]

       Isolate variable x:

[tex]x=\frac{2016000}{1680}[/tex]

[tex]x=1200[/tex]

Answer:

(-9x^2-2x)-(-9x^2-3x)

Answer:

Quick Answer it is A

Step-by-step explanation:

You have developed an angle bisector.

That means that JKM = LKM

B: is incorrect. The 1/2 should go on the angle on the left, not the one where it is

C: is incorrect. 1/2 of the given angle cannot be the same as the bisected angle.

D: is wrong. A bisected angle can't be twice as big as the given angle before it is bisected.

Answer:

The answer is "Grocery sales are lower or no different on Sunday than on other days"

Step-by-step explanation:

Its null hypothesis does not always consider any discrepancy between both the comparable qualities throughout facts and figures. Furthermore, researchers recommend also have lower or even no opposite transactions for Sunday than with other days, because there is no connection between grocery sales and Saturdays and Sundays.

Answer:

$19.44

Step-by-step explanation:

$108 x 18% = $19.44

Answer:

If the two numbers are x and y, then:

x + y = 8

18 - 2x = 4y - 2.

When we subtract y from both sides in our first equation we get:

x = 8 - y, so:

18 - 2(8 - y) = 4y - 2

18 - 16 + 2y = 4y - 2

2 + 2y = 4y - 2

2y = 4

y = 2

Since x + y = 8, and y = 2, x = 6, and since 6 > 2, the larger number is 6.

Answer:0.0001333

Step-by-step explanations :

Answer:

In the first coordinate

Step-by-step explanation:

For x = -3, the point is either located in 2nd or 3rd quadrant.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

A coordinate is represented as -

P(x, y)

where -

[x] is abscissa

[y] is ordinate

We have the following coordinate -

(-3, 2)

For x = -3, the point is either located in 2nd or 3rd quadrant

Therefore, for x = -3, the point is either located in 2nd or 3rd quadrant.
