Answer:

  x ∈ {π/18, 5π/18, 13π/18, 17π/18, 25π/18, 29π/18}

Step-by-step explanation:

Using the trig identity ...

  cos(2x) = 1 -2sin²(x)

we can rewrite the equation as ...

  (1 -2sin²(3x)) -5sin(3x) +2 = 0

  2sin²(3x) +5sin(3x) -3 = 0 . . . . . standard form

  (sin(3x) +3)(2sin(3x) -1) = 0 . . . . factored form

There are no real values of x that will make the first factor zero. The second factor is zero when ...

  sin(3x) = 1/2

  3x = arcsin(1/2) +2nπ   or   (2n+1)π -arcsin(1/2)

  x = 1/3(π/6 +2nπ)   or   1/3((2n +1)π -π/6)

  x = (12n+1)π/18  or  (12n+5)π/18

  x ∈ {π/18, 5π/18, 13π/18, 17π/18, 25π/18, 29π/18}

Answer:3/6 in simplest fraction form is 1/2.

Answer:

0.393701 cm = 1 in

Step-by-step explanation:

We want to find the number of centimeters in 1 inch.

First, the two conversion rates we need to use:

1m = 100 cm

1m = 39.3701 in

From these two equations, we can conclude that:

100cm = 1m = 39.3701 in

100cm = 39.3701 in

Because we want to find the total number of centimeters in 1 inch, we need to divide both sides by 39.3701

We will get:

(100cm)/39.3701 = (39.3701 in)/39.3701

0.393701 cm = 1 in

This equation gives us the number of centimeters in one inch.

Answer:

ok for this problem lets convert all of the number into decimals to make it easier.

7.5 is already a decimal

7 2/5 as a decimal is 7.4

7.69() is already a decimal  

ok so 7.4 is lowest

7.5 is next

7.69 is highest

Answer:

In order from least to greatest is [tex]7\frac{2}{5},7.5,7.69[/tex]

Step-by-step explanation:

In order from greatest to least is the other way around

[tex]2/5 = 0.4[/tex]

So [tex]7.4[/tex]

Answer:

36x² + 24x + 300 ft²

Step-by-step explanation:

→ Area of rectangle = Length × Width

→ Area of rectangle = (12x + 8) ft × (3x + 15) ft

→ Area of rectangle = 12x(3x + 15) + 8(3x + 15) ft²

→ Area of rectangle = 36x² + 180 + 24x + 120 ft²

→ Area of rectangle = 36x² + 24x + 300 ft²

Answer:

2/3

Step-by-step explanation:

P ( 8 or more) = number that are 8 or more) / total

                        = (6+4) / ( 2+3+6+4)

                         = 10/15

                          =2/3

Answer:

Let the total number of pupil be x.

Given that,

Number of pupils that received a grade of 90=9

Percentage of pupil that receive a grade of 90=18%

So,

18% of x=9

18x/100=9

x=50

Hence, there are 50 pupils in the class.

Answer:

ArcAB should be 182.

Step-by-step explanation:

You are not going to believe this, because the diagram is very misleading. AC is the same as the central angle. The central angle is twice m<ABC.

The central angle = 2*91 = 182

Answer:

B.

Step-by-step explanation:

Judging by the picture, it appears that you are correct. The pattern seems to go as follows:

1. Blue (with one line)

2. Red (with two lines)

3. Blue (with three lines)

This means that your final step should be red with four lines, and we can eliminate D as there is no sign that the line should branch off that way (based on the pattern that we already have). Hope this helps and please let me know if you still need help!

Answer:

-4

Step-by-step explanation:

f(x) = 10 - 2x

substitute 7 in place of x

f(7) = 10 -2*7

=10 - 14

=-4

therefore the value of f(7) is -4.

Answer:

87.5 square inches

Step-by-step explanation:

(For Diagram,Please Find in Attachment)

Given, in diagram of the belt Knuckle there are 4 Triangles (2 are of same dimensions & another 2 are of same dimensions) and a Rectangle .

Now For Area of belt Knucle, We have to First Calculate the area of 4 triangles and Area of Rectangle.

∴ Area of 2 Triangle with given dimensions ( height = 2.5 inches & base = 9 inches )

Area = 2×(1/2×b×h) ⇔ 2×(1/2×9×2.5)

Area= 22.5 square inches

∴ Area of another 2 triangle with given dimensions ( height = 5 inches & base = 4 inches )

Area = 2×(1/2×b×h) ⇔ 2×(1/2×4×5)

Area= 20 square inches

∴Area of Rectangle with given dimensions ( Length = 9 inches & Width = 5 inches )

Area= length × Width ⇔ 9×5 ⇒ 45 square inches

Now, Area of belt Knucle=Sum of Area of 4 Triangles + Area of Rectangle

Area of belt Knucle = 87.5 square inches

2,247

Step-by-step explanation:

Answer:

a) 19/20

b) 1/20

Step-by-step explanation:

a) calculate the fraction of the attendants time will be spent servicing cars

l / L > 0 =  Ц / [ Ц -  λ ] = 20 --- ( 1 )

Ц (service )  = 15 hour

∴ λ ( arrival rate )  = 14.25

P = λ / Ц  = 14.25 / 15 = 0.95 = 19/20

b) Fraction of potential customers lost

Ls = P / ( 1 - P )

where ; P = 19/20

Ls ( fraction of potential customers lost ) = 19/20 / ( 1 - 19/20 )  = 19

hence proportion of customers lost = 1 - 19/20 = 0.05 = 1/20

The answer is C .

Step-by-step explanation:

Here's your answer in image

Answer:

The answer is C

Step-by-step explanation:

Your Answer is in the above image

Answer:

Step-by-step explanation:

Integrating each term with respect to x, we get:

            x^3          x^2

f(x) = 9--------- + 4------- - 4x + C

               3            2

We are told that if x = 0, f(x) = -7, and so C must equal - 7.  

The solution is

            x^3          x^2

f(x) = 9--------- + 4------- - 4x - 7,   or   f(x) = 3x^3 + 2x^2 - 4x - 7

Answer:

D. Average deviation from the mean in the group must be squared to be meaningful.

Step-by-step explanation:

The average variability from mean is not calculated with mean square of the selected group. The deviation scores calculated by subtracting participant score from the mean.  

Step-by-step explanation:

the answer is in the above image

Answer: When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

Reflection in the y -axis:

The rule for a reflection over the y -axis is (x,y)→(−x,y) .

Reflecting over any other line. Notice how each point of the original figure and its image are the same distance away from the line of reflection (x = –2 in this example).

It is simple enough to identify whether or not a given function f(x) is a linear transformation. Just look at each term of each component of f(x). If each of these terms is a number times one of the components of x, then f is a linear transformation. are linear transformations.

First shift three units to the left, so the line of reflection becomes the y axis, then flip, and finally remember to shift three units back to the right to put the center line back where it belongs. (This gives the f(6−x) solution you already know).
