Answer:

130

Step-by-step explanation:

There are 9,232,320 ways to split 14 people into seven pairs.

To split 14 people into seven pairs, we need to find the number of ways to arrange the people into those pairs.

Let's break down the process step by step:

1. Selecting the first pair: We have 14 people to choose from for the first person in the first pair. After selecting the first person, we have 13 people remaining to choose from for the second person in the pair. Since the order of selection doesn't matter, we divide by 2 to account for the fact that we have counted each pair twice (e.g., choosing A then B is the same as choosing B then A).

Therefore, the number of ways to select the first pair is (14 * 13) / 2 = 91.

2. Selecting the second pair: We have 12 people remaining after forming the first pair. Similar to the first pair, we have 12 choices for the first person and 11 choices for the second person in the second pair. Again, we divide by 2 to account for the order of selection.

The number of ways to select the second pair is (12 * 11) / 2 = 66.

3. Continuing this process, we select pairs until all 14 people are paired up. Each time, the number of remaining people decreases by 2.

So, the total number of ways to split 14 people into seven pairs is:

91 * 66 * 40 * 24 * 10 * 6 * 2 = 9,232,320.

Therefore, there are 9,232,320 ways to split 14 people into seven pairs.

In arithmetic progression common difference is given by

d = nth term - (n-1)th term.

In geometric progression common ratio is given by

r = nth term / (n-1)th term.

Another thing  important to note is that in both AP and GP common difference and common ratio remains same for any two consecutive terms which can be calculated using above formula.

we will be using this concept to solve this problem.

________________________________

Let look at the problem

series

11, 6 ,1

Lets try to find common difference for this series

common difference of third and second term = 1-6 = -5

common difference of  second term and first term = 6 -11 = -5

Thus, we see that common difference is same in both case ,

hence it can be concluded that series is Arithmetic progression.

another way to validate this is

nth term of AP is given by

nth term = a + (n-1)d

where a is first term

lets try to find third term using this formula and using d = -5 and a = 11

3rd term = 11 + (3-1)-5 = 11 + 2*-5 = 11- 10 = 1

Thus, we see that third term calculated is same as given in series i.e 1

Hence series is Arithmetic progression validated as well.

______________________________________________

Problem is solved but lets see if the series is GP or not

common ratio of third and second term = 1/6 = 1/6

common ratio of  second term and first term = 6 /11

Thus, we see common ratio is not same for the two consecutive term in the series and hence series cannot be geometric progression.

Answer:

The equation that models how far from the tip of the saw is from the wood in terms of time is x(t) = 10×cos(2×π×t) + 17

Step-by-step explanation:

The given parameters are;

Length of the saw blade = 40 cm

Thickness of the wood across = 8 cm

Length of blade between wood saw handle with hand extended = 5 cm

Length of the tip from the wood at the above time = 40 - 8 - 5 = 27 cm

Length of blade between wood saw handle with saw pulled inwards = 25 cm

Length of the tip from the wood at the above time = 40 - 8 - 25 = 7 cm

Time for one complete cycle = 1 second

We note that the basic equation for oscillatory motion is of the form;

x(t) = A·cos(ωt) + d

Where:

A = Amplitude of the motion = (27 - 7)/2 = 10 cm

ω = Angular frequency = 2·π/T

ωt = Motion's phase

t = Time of the motion

d = The middle location = 27 - 10 = 17 cm

T = The time to complete a cycle = 1 s

Therefore;

ω = 2·π

Given that he stars with his arm extended out, we have;

27 = 10×cos(2×π×0) + 17

Therefore, the equation that models how far from the tip of the saw is from the wood in terms of time is x(t) = 10×cos(2×π×t) + 17.

Greatest common factor of 32 and 44 is 4:

Answer:

-11

Step-by-step explanation:

You need to find the difference in y-coordinates and divide that difference into a 7:3 ratio. Then you add that to the y-coordinate of point J.

Difference in y:

-20 - 10 = -30

7 + 3 = 10

7/10 * (-30) = -21

Add -21 to 10:

10 + (-21) = -11

The y-coordinate is -11.

Answer:

r^2 = 45÷2 x^2

Step-by-step explanation:

Details of cone:

Radius(r) = 5x cm

Height(h) = 12x cm

Slant height(l) = √(12x^2 + 5x^2)

l = 13x cm

Total surface area of a cone (T. S. A) = πrl + πr²

T. S. A = π * 5x * 13x + π5x^2

T.S.A = π65x^2 + π5x^2

T.S.A = π65x^2 + π25x^2

T.S.A = 90πx^2 - - - - - (1)

Details of sphere:

Radius (r) = r cm

Total surface area = 4πr²

Total Surface area of sphere= 4πr²cm - - - (2)

Equating (1) and (2) to calculate r

4πr² = 90πx^2

r^2 = 90πx^2 / 4π

r^2 = 90π (x^2) / 4π

r^2 = 45/2 (x^2) ;

r^2 = 45÷2 x^2

Answer:

The ball is higher than 10 feet off the ground when the time is between 2 to 5 seconds

Step-by-step explanation:

In the above question, we are given the equation:

h(t) =-t²+7t.

We are asked to find the time (t) when the ball will be higher than 10 feet.

h(t) = height = 10 feet.

So we have:

10 = -t² + 7t

t² - 7t + 10 = 0

We have a quadratic equation hence we factorise.

t² - 5t - 2t + 10 = 0

(t² - 5t) +(2t - 10)= 0

t(t - 5) + 2 (t - 5) = 0

(t - 2) (t - 5) = 0

t - 2 = 0, t = 2

t - 5 = 0, t = 5

t = 5 and t = 2

Therefore, the ball is higher than 10 feet off the ground when the time is between 2 to 5 seconds.

Step-by-step explanation:

We can use any two points in the table and the slope formula

m = (y2-y1)/(x2-x1)

Using ( (0,4) and ( -2,10)

  = ( 10 -4)/(-2 -0)

  = 6/-2

  = -3

Answer:

B. -3

Step-by-step explanation:

If you were to put it into a problem

-2x + 4

(the 4 because that's where it intercepts the y axis)

and if you were to substitute in 4 for the x you would get

-2(4) + 4 = -4 which wouldn't give you -8

so now you try -3x + 4

Then substitute 4 for x

-3(4) + 4 = -8 so then you would substitute 6 by four just to be sure

-3(6) + 4 = -14 so the answer would be B.

Answer:41.7

48x = 2000

Divide both sides by 48

X= 2000/48

The perimeter of a rectangle is calculated by:

[tex]\boxed{P=width +width+length+ length}[/tex]

Remember: In a rectangle, opposite sides are equals.

If we know how much is the width, then it's just apply it to the expression:

[tex]P=width+width+length+length\\312 =68 + 68 + length + length\\312 = 136+(2\cdot length)\\312 - 136 = 2\cdot length\\2\cdot length = 176\\length = \frac{176}{2} \\length = 88[/tex]

Therefore, the length of the pool is 88m.

The diagram that will show possible angle measures of a triangle is. A triangle has angle lengths of 32 degrees, 115 degrees, and 33 degrees.

It should be noted that the sum of the angles that are in a triangle equals 180°. Therefore, in this situation, we'll need to add the values and the one that gives 180° is the right answer.

Therefore, when a triangle has angle lengths 32 degrees, 115 degrees, and 33 degrees, the sum will be:

= 32 + 115 + 33

= 180°

y = x-1

Step-by-step explanation:

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y= 1x -1

y = x-1

The slope intercept form is,

y = x -1

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Since, The slope intercept form is

y = mx + b

where m is the slope and b is the y intercept

Here, We have;

The slope of a line is 1, and the y-intercept is -1.

Hence, We get;

Answer:

(0, -2)

Step-by-step explanation:

The question is not complete, the coordinates of point A are not given. Let us assume A = (3, 2).

If a point D [tex](x_1,y_1)[/tex]is rotated about a point E([tex]x_2,y_2[/tex]), First E is made the center of origin. This is done by making a new point F = D - E. Therefore F = [tex](x_1-x_2,y_1-y_2)[/tex].

If a point D [tex](x_1,y_1)[/tex] is rotated 180 degrees, the new ordinates becomes [tex]D'(-x_1,-y_1)[/tex]

If a point D [tex](x_1,y_1)[/tex] is translated x units down,, the new ordinates becomes [tex]D'(x_1,y_1-x)[/tex]

Let us assume A = (3, 2).

If ABCDE is rotated 180 degrees clockwise around A, Firstly A is made the center of origin. For point A, the new point by making A the center of origin is A' = A - A = (3, 2) - (3, 2) = (3-3, 2-2) = (0, 0). Therefore the 180 degrees rotation becomes A'' = (-0, -0) = (0,0)

If it is then translated 2 units down, the new coordinates are (0, 0-2) = (0, -2)
