Answer 2
Answer:

                 The number is:

                          1260

Step-by-step explanation:

We know that the number of ways of arranging n items is calculated by the method of permutation.

If n letters are to be arranged such that there are [tex]r_1,r_2[/tex] items each of the same type.

Then, the number of ways of arranging is:

                   [tex]\dfrac{n!}{r_1!\times r_2!}[/tex]

We are asked to find the number of ways of arranging the letters of "Balloon"

There are a total of 7 words such that 'l' occurs two times and 'o' occurs two times.

Hence, the number of ways of arranging them are:

     [tex]=\dfrac{7!}{2!\times 2!}\\\\=\dfrac{7\times 6\times 5\times 4\times 3\times 2!}{2!\times 2}\\\\=1260\ ways[/tex]

The circumference of a circular swimming pool is 100 feet. If the radius of the pool is doubled, what will the new circumference be?

Answers

The new circumference is 200
Circumference, C= 2πr

Solve for r
C = 2πr
100 = 2πr
100/2π = r
15.92 ft = circumference of circle with C = 100ft

Doubled radius
15.92(2) = 31.83 ft = new radius
C of new circle = 2πr
C = 2π(31.83)
[C = 200 ft]
= Circumference of new circle with doubled radius.

c.
Vertical stretch by a factor of 9
b.
Horizontal translation to the right 9 units
d.
Vertical translation down 9 units

Answers

Answer:

Option D is correct .i.e., Vertical translation down 9 units

Step-by-step explanation:

Given Function is y = cosec x - 9

Here basic function or parent function is y = cosec x

1. When constant ' a ' is added to to parent function or basic function then the function is translated vertically upward by a units.

2.  When constant ' a ' is subtracted from parent function or basic function then the function is translated vertically downward by a units.

Therefore, Option D is correct .i.e., Vertical translation down 9 units

Which answer is the equation of the line?

(picture is my choices)

Answers

The general form of a straight line equation is given by

y = mx + c

Where 'm' is the gradient and 'c' is the y-intercept

We have:
m = ²/₃
c = -2

Plug in the value of 'm' and 'c', we have:

y = ²/₃x - 2

Answer: Second option


The generic form of straight line consisting of slope and y intercept  is given by

y = mx + c

Where 'm' is the slope of the straight line  and 'c' is the y-intercept

In the problem, it is given that slope of the line is 2/3 and y intercept is -2 :

A stereo system cost $275. It was on sale for 15% off. The sales person receives a 2% commission. How much of a commission do they receive?

Answers

the price of the stereo on sale   
is 
275 - ( 275x15% ) =
233.75 

the comission is 233.75 x 2 % =
233.75 x 2/100 = 4.675 

Answer:

They receive $4.68 as a commission

Step-by-step explanation:

The cost of stereo system = $275

Price after discount of 15% = 275 - (15% × 275)

                                             = 275 - ( 0.15 × 275)

                                             = 275 - 41.25

                                             = $233.75

2% commission of the sales person = 2% × 233.75

                                                           = 0.02 × 233.75

                                                           = $4.675 ≈ $4.68

They receive $4.68 as a commission

The distance a body falls from rest varies directly as the square of the time the body is falling. If a body falls 81 ft. in 3 seconds, how far will it fall in 7 seconds?

Answers

You are saying that X = k*t^2 where k is a constant
Plugging in the 64 ft and 2 seconds k = 16 so,
X = 16*49 = 784 ft .
Let the distance = D
Let the time taken = T
From the question, we are told that distance is directly proportional to the square of the time the body takes to fall,
that is, D = K *[T^2]
K is a constant and we have to find its value;
Using the value given in the question;
D = 81 feet
T = 3 seconds
From our original equation,
K = D/ [T^2] = 81/3^2 = 81/9 = 9.
Therefore, K = 9
To find the distance through which the body fall in 7 seconds, we have,
K = 9
T = 7 seconds
D = K * [T^2] 
D = 9 * [7*2] = 9 * 49 = 441.
Therefore, the body will fall through a distance of 441 feet in 7 seconds.


A student pays for 8.9 pounds of apples with a $10 bill. How much change does the student receive if the apples are .99 per pound

Answers

the student will receive $1.2 

8.9 x .99 =  8.8
10 - 8.8 = 1.2

Answer:

[tex]\$\,1.19[/tex]

Step-by-step explanation:

Quantity of apples bought by the student = 8.9 pounds

Amount paid by the student for apples bought by the student = [tex]\$[/tex] 10

If cost of one pound of apples is [tex]\$[/tex] 0.99  then cost of  8.9 pounds = 0.99 × Quantity of apples bought by the student = [tex]8.9\times 0.99=8.811[/tex]

Therefore,

Amount of change that the student receive if the apples are .99 per pound = Amount previously paid by the student for apples bought by the student when the student pays [tex]\$[/tex] 10 - Amount  paid by the student for apples if the apples are .99 per pound = [tex]\$ \,10-\$ \,8.811=\$\,1.19[/tex]

How to determine the function is even odd or neither

f(x)=5-3x

Answers

if the function is mirrored about the y axis, it is even

 use -x in place of x and compare the equations

lets use 2 for x

 so given formula would be 5-3(2) = 5-6 = -1

replace x with -x you would have 5-3(-2) =5-(-6) = 5+6 =11

since -1 does not = 11 the function is neither


even =f(x), odd = -f(x), neither f(x) doesn't equal -f(x)


example of odd:

f(x) = x^5 +x, replace x with -x

f(-x) = (-x)^5 +-x

=-x^5-x

=-(x^5+x)

=-f(x)

ODD


Example of even:

f(x) = 1-x^4

f(-x) = 1-(-x)^4

=1-x^4

=f(x)

EVEN


Example of Neither:

f(x) = 2x-x^2

f(-x) = 2(-x)-(-x)^2

=-(2x+x^2)

does not equal f(x)

NEITHER

how many lines of reflectional symmetry does an equilateral triangle have

Answers

Answer:

only 3 lines of symmetry does an equilateral triangle have.

Explanation:

Since a triangle can have 3 or 1 or no lines of symmetry.

In a equilateral triangle:

*All sides are equal

*All angles are equal i.e each of 60 degree.

Symmetry is  when there is an exact replica or reflection of a shape or a line.    

Line of symmetry: It is an imaginary line that runs through the center of a line or shape creating two perfectly identical halves.

A line of symmetry for a given triangle must go through each vertex as shown in figure;

Therefore, the equilateral with 3 sides equal has 3 lines of symmetry.



An equilateral triangle has [tex]\fbox{\begin\\\ 3\text{lines}\\\end{minispace}}[/tex] of reflection symmetry.

Further explanation:

A triangle is a two dimensional closed figure which is formed when three non-collinear points are joined. There are three sides, three angles and three vertices of a triangle.

On the basis of sides and angles triangles are classified as follows:

1) Scalene triangle: A triangle in which all the sides and the angles have a unique value is called a scalene triangle.

2) Isosceles triangle: A triangle in which any two sides or two angles are equal then the triangle is called an isosceles triangle.

3) Equilateral triangle: A triangle in which all the sides and the angles are equal then the triangle is called an equilateral triangle.

A line of reflection is defined as a line across which the image of a figure or an object is reflected.

The reflected image is of same size as of the original image.

In case of an equilateral triangle if we drop a median from one of the vertex of the triangle to its opposite side then it is observed that the median divides the equilateral triangle into two equal halves.

From figure 1 (attached in the end) it is observed that the median AD of an equilateral trinagle [tex]\triangle \text{ABC}[/tex] divides the triangle into two equal halves.

As per the above statement it is concluded that the median AD is the line of reflection symmetry for the equilateral triangle [tex]\triangle \text{ABC}[/tex].

Now, similarly if we drop a median form the vertex B or C to its opposite side then it is observed that the triangle into two equal halves.

Figure 2 (attached in the end) shows that the median dropped from the vertex B and C divides the triangle into two equal halves.

This implies that the median BD and CD are also the line of reflection symmetry for the equilateral triangle ABC.

So, the total number of lines of reflection symmetry for an equilateral triangle is [tex]3[/tex].

Thus, an equilateral triangle has [tex]3[/tex] lines of reflection symmetry.

The author purchased a slot machine configured so that there is a 1/2000 probability of winning the jackpot on any individual trial. Although no one would seriously consider tricking the author, suppose that a guest claims that she played the slot machine 5 times and hit the jackpot twice. Find the probability of at least 2 jackpots in 5 trials. Find the probability of exactly 2 jackpots in 5 trials

Answers

Finding the Probability of exactly 2 Jackpots in 5 Trials:
We are given that the probability of winning a jackpot on any individual trial is 1/2000. However, this is just for one trial. To get the probability, we need to transform the question into numbers. We can use this "formula" to do this:
TImes Winning Jackpot/ Number of Trials
If we use this formula, we can create a fraction of 2/5. Now, all that is left is to multiply 2/5 by 1/2000 to get 2/10000, which can be simplified to 1/5000. This means that the guest had a 1 in 5000 chance of winning 2 jackpots out of 5 trials. 

Finding The Probability of at least 2 jackpots in 5 trials
The answer to this problem is basically the same as before, but the answer should be phrased differently. Your new answer would be that the guest had less than 1 in 5000 chance of winning 2 jackpots in 5 trials.
