Find the length of side b

I need help plss

Given :

An expression (cos 6m)(cos 2m) .

To Find :

We need to express it in terms as sum or difference.

Solution :

We know,

cos( A + B ) = cosA cos B - sin A sin B

cos( A - B ) = cosA cos B + sin A sin B

Adding both the equations we get :

2cos A cos B = cos( A + B) + cos( A - B )

or

cos A cos B = cos( A + B) + cos( A - B )/2

Putting value of A = 6m and B = 2m in above equation, we get :

(cos 6m)(cos 2m) = cos( 6m + 2m ) + cos( 6m - 2m )/2

(cos 6m)(cos 2m) = cos(8m) + cos(4m)/2

Hence, this is the required solution.

Answer:

IT's -3.6 & 14.4 so D is the correct answer

Step-by-step explanation:

x= -3.6 y= 14.4

HOW I SOLVED IT

-3.6 x 3 = -10.8    2 x 14.4 = 28.8 - 10.8 = 18  so correct since it must equal to 18

-2/3 x -3.6 =2.4  + 12 = 14.4 so correct since y = 14.4

Brainilest would be appreciated :)

Answer:

y = -4/5x + 7/5

Step-by-step explanation:

Use slope intercept form to find the equation for the line:

y=mx+b

y= -4/5x + 7/5

Answer:80

Step-by-step explanation: if you do 45:100% and then x36 you get the result

Answer:

30 degrees

Step-by-step explanation:

If you were to draw a number line, 15 and -15 are both 15 units away from 0. So, 15 + 15 =30

Answer:

1 is 22; 2 is 19; 3 is 16; 4 is 13; 5 is 10

Step-by-step explanation:

Give me that crown again

Answer:

22, 19, 16, 10

Step-by-step explanation:

y = 25-(3*1)= 22

y = 25-(3*2)= 19

y = 25-(3*3)= 16

y = 25-(3*5)= 10

Answer:

it would be at 3

cause double negatives cancel out- if u c something like -- or -(-) they would become a positive- so you would plot it at positive 3

hope this helps (again lol)

Step-by-step explanation:

Answer:

plot at 3

Step-by-step explanation:

a negative number times another negative number will result in a positive number

therefore,  - (-3)=3

Answer:

1.5 = 150%

.15 = 15%

.01 = 1%

.1 = 10%

Please give brainliest

Answer:

1.5 = 150%

.15 = 15%

.01 = 1%

.1 = 10%

Step-by-step explanation:

The complement of 45° is the angle that when added to 45° forms a right angle (90° ).

Since you know a line is = 180*

if angle EFG is 125, we can get angle EFD = to 180-125=55

And since we know that the line ED is congruent to line EF, angle EDF is = 55

180-55*2= 70

angle DEF=70

Answer:

884

Step-by-step explanation:

We know the ratio of A to B is 5:8

let x = the multiplier

then

5x = amt of compound A

and

8x = amt of compound B

:

5x + 8x = 884

13x = 884

x = 884/13

x = 68 is the multiplier

therefore

5(68) = 340 millilters of compound A needed

:

:

Confirm our answer. Find the amt of B

8(68) = 544 ml of B

340 + 544 = 884

Given:

The function on the Input output table.

To find:

The range of the given function.

Solution:

We know that, range is the set of output values.

From the given table it is clear that, hours of training is the input variable and pay per month is the output value.

So, range of the given function is the set of pay per month.

Range = {1100, 1200, 1300, 1400, 1500, 1600, 1700}

Therefore, the correct option is A.

Answer:

The approximate diameter of the larger tank is 8.10 meters

Step-by-step explanation:

Here, we want to calculate the diameter of the larger tank

The volume of a sphere

V = 4/3 * π * r^3

Let us calculate the volume of the standard model

That will be;

Since diameter is 6 and r = d/2

r = 6/2 = 3 meters

V = 4/3 * π * 3^3 = 36 π m^3

Now, the volume of the larger tank is 2.5 times of this;

The volume of the larger tank is 2.5 * 36 π = 90 π m^3

So we can calculate the radius of this before we calculate its diameter

4/3 * π * r^3 = 90 π

4r^3/3 = 90

r^3 = 270/4

r^3 = 67.5

r = 3x√(67.5)

r = 4.07 m

Diameter here is 2 times this

= 4.07 * 2 = 8.14

Answer:

8.1

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

You have to list the numbers in the correct order then fond the one that falls in the middle, if there are 2 numbers that fall in the middle, then you add those 2 then divide by 2.

Answer:

8

Step-by-step explanation:

Arrange the set of numbers from least to greatest:

3,6,6,6,8,9,16,16,18

Start from both ends and cross them off until you're left with just one.

6,6,6,8,9,16,16

6,6,8,9,16

6,8,9

8

The median is 8 because that's what you're left with.
