It might be 24 but probaly not.

Step-by-step explanation:

It is the first 3 , but am not sure about the last one.

The domain represents interval notation is (–∞, 7) U (7, ∞) which is the correct answer would be an option (A)

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

For all other x-values, the graph appears to be defined. Thus, with the exception of x = 7, all real numbers should fall under the function's domain. This is what that would look like in interval notation:

It is possible to write the interval (–∞, ∞). as the set of all real numbers. Keep in mind that infinity∞ or -∞  is not a real number. Both ends are shown to be excluded from the interval by the rounded brackets.

All real numbers less than but not equal to 7 are contained in the set (-∞,7). (both ends are excluded.) The collection of every real number greater than but not equal to is.

All real numbers less than and higher than are combined to form the set of all real numbers that are not equal to 7. The union operator joins two intervals together.

Hence, the domain represents interval notation is (–∞, 7) U (7, ∞)

Answer:

2x(3x + 2)

Step-by-step explanation:

Answer

102

Step-by-step explanation:

X means 3 not times, lots of people mess that up sometimes. Anyways, do 8+3 which equals 11. 8+3=11. So next what you do is you do 11 + 16 which is 27,

equations:

8+3=11

11+16=27

21/1=27

27/4= 6.75

6 x 3= 27

27 + 72 + 3= 102

Then go back to the beginning and do 1/4. If this confuses let me fix it.

now divide it with 4. Look at the equations list. Okay now do 6.72/4x. MAKE SURE TO MULTIPLY DON'T DIVIDE! You multiply 6 and 4 then you add 72 and three! Then you should end up with 102! I hope this worked message me back if it did :)

Answer:

28

Step-by-step explanation:

If a ribbon connects two skydivers, and there are 8 skydivers total, then we can do 8C2, which is equal to (8*7)/2, which is equal to 28. An alternate solution is to think of it this way. Skydiver 1 is connected to everyone else, which is 7 other people. Skydiver 2 is connected to everyone else but Skydiver 1, which is 6 other people. This goes on until Skydiver 8 is already connected with everyone. So we have 7+6+5+4+3+2+1+0, which is also equal to 28.

The total number of pieces of ribbons that were used in the skydiving act is 28 ribbons

What are Combinations?

The number of ways of selecting r objects from n unlike objects is:

The equation for combination is

ⁿCₓ = n! / ( ( n - x )! x! )

where

n = total number of objects

x = number of choosing objects from the set

Given data ,

The total number of skydivers in the plane n = 8 skydivers

Each  skydiver was connected to each of the other skydivers with a separate pieces of ribbon

So , the number of choosing skydivers x = 2

Now , the total number of ribbons used is calculated by combination

So , the equation is

ⁿCₓ = n! / ( ( n - x )! x! )

Substitute the value of n and x in the equation , we get

⁸C₂ = 8! / ( ( 8 - 2 )! x 2! )

      = 8! / ( 6! x 2! )

      = 8 x 7 / 2 x 1

      = 56 / 2

      = 28 ribbons

Hence , The total number of pieces of ribbons that were used in the skydiving act is 28 ribbons

Answer:

first dude is right :)

Step-by-step explanation:

Answer:

x=10.93 or 10.9

Step-by-step explanation:

To find x we use sin

sin(40) = 0.6427876097  then * 17

= 10.9273

= 11

We can check and plug in answer as inverse to find other side

11/sin (40degree) x (90 degree) = 17.11

If we plug in the original 10.9273 we actually find 17

So we should show the correct amount 10.9273 and if rounding try 10.93

10.93/sin (40 degree) x sin (90 degree) = 17.00

Answer:

x = 45 degree as it is an alternate angle we use 135 degree to prove supplementary angles across the straight line add up to 180 degree.

Therefore we prove 180-135 = 45 degree and say all angles on straight line add up to 180 degree, and recognize x is an alternate angle as the arrow straight lines are parallel and create precise alternate lines from which we can prove multiple supplementary and alternate angles.

Supplementary can be either angle will always be supplementary from either 45 degree angle matched with any 135 degree as they don't have to be together to be supplementary they only have to equal 180 degree to be a supplementary angle.

Answer:

x =16

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adjacent/ hypotenuse

cos 60  = 8/x

Switch the x and the cos 60

x = 8/cos 60

x =8 / (1/2)

x =16

Answer:

y=x-6

Step-by-step explanation:

The x-intercept is found replacing y = 0, as follows:

Function: y = -3x + 8

x-intercept:

0 = -3x + 8  

3x = 8

x = 8/3

Function: y = -3x + 6

x-intercept:

0 = -3x + 6

3x = 6

x = 6/3 = 2

Function: y = -x - 8  

x-intercept:

0 = -x - 8  

x = -8

Function: y = x - 6

x-intercept:

0 = x - 6

x = 6

The last option is the only one in which x-intercept is x = 6.

Step-by-step explanation:

The sine of an angle is the length of the opposite side divided by the length of the hypotenuse, which in this case is 40/48=5/6. Therefore, that angle is the arcsin of this, or approximately 56.44 degrees, or answer choice C. Hope this helps!
