ANSWER

C)5103.3735

EXPLANATION

The recursive definition of the given sequence is;

[tex]f(1) = a_1 = 6[/tex]

and

[tex]f(n) = a_n = (1.2) \times f(n - 1)[/tex]

The explicit definition is

[tex]f(n) = a_n =6 (1.2)^{n - 1} [/tex]

We substitute n=38 to obtain:

[tex]f(38) = a_ {38}= 6(1.2)^{37} [/tex]

[tex]f(38) = 5103.3735[/tex]

The correct choice is C.

That would be a rectangular pyramid. The net would consist of a rectangle and 4 triangles

The  three-dimensional figure is:

                      Rectangular Pyramid.

Net of a three dimensional figure--

A net of a three dimensional figure is the pattern which is made with the help of all the faces of a solid.

The net is used to identify the three dimensional solid it will form.

Here, the net is 1  rectangle and a number of triangles.

a)

rectangular prism

The net of this solid are made by using six rectangles.

Hence, option (a) is incorrect.

b)

Rectangular Pyramid--

It is a three dimensional figure which is formed by taking a rectangle as a base and  4 triangles as it's other faces.

Hence, the net of this solid is made using 1 rectangle and a number of triangles.

c)

Triangular prism--

It has three faces as parallelogram and 2 as triangles.

Hence, option: c is incorrect.

d)

Triangular Pyramid--

A triangular pyramid also known as a tetrahedron is a three dimensional figure which is composed of four triangles.

Hence, option: d is incorrect.

You can set up a proportion based on the information you know. There are several ways to do this but here's one: [tex]\frac{8}{4} = \frac{s}{16}[/tex] because the 8 corresponds to the 4 and the s correspnds to the 16. Cross multiply to get 8 * 16 = 4s → 128 = 4s → 32 = s so the value of s is 32m

The value of s is 32 m.

Similar trapezoids are trapezoids whose sides are in a ratio. the ratio is known as the scaled factor.

A scale factor is a factor by which the image is been enlarged. for example, the scale factor of 10 means each side will be multiplied by 10, resulting in a figure that is 10 times the real figure.

As given to us, ABCD is similar to trapezoid EFGH. therefore, the sides of the trapezoid are in a ratio.

Thus we can write,

[tex]\bold{\dfrac{EH}{AD}=\dfrac{GH}{CD}}[/tex]

substituting the values we get,

[tex]\bold{\dfrac{s}{16}=\dfrac{8}{4}}[/tex]

[tex]\bold{s=\dfrac{8\times 16}{4}=32}[/tex]

Hence, the value of s is 32 m.

A square is always a rhombus because it satisfies all the properties of rhombus but every rhombus cannot a square.

Therefore, If KLMN is a square, then it must be a rhombus.

Have A Fantastic Day

TheBlueFox

Answer:

It must be a rhombus

Step-by-step explanation:

It’ll be (5,4) because it’s on the same Y line (aka 4) just like (1,2) and (5,2).

The coordinates of the fourth vertex of the rectangle are (5, 4).

A rectangle is a closed two-dimensional figure with four sides. The opposite sides of a rectangle are equal and parallel to each other and all the angles of a rectangle are equal to 90°.

Given that, three vertices of a rectangle are located at (1,4), (1,2), and (5,2).

The intersection point of diagonals of rectangle is midpoint of each diagonal.

Let the fourth coordinate be (x, y). By the above property we get

Now, the midpoint of (1, 4) and (5, 2) is

[(1+5)/2, (4+2)/2] =(3, 3)

Thus, (3, 3) =[(x+1)/2, (y+2)/2]

3=(x+1)/2, 3=(y+2)/2

6=x+1, 6=y+2

x=5, y=4

Therefore, the coordinates of the fourth vertex of the rectangle are (5, 4).

Final answer:

By substituting the x and y values from each ordered pair into the two given equations, we can determine whether the ordered pairs (0,-2), (5,3), (-2,16), and (-4,-9) are solutions. An ordered pair is a solution if it satisfies both equations of the system.

Explanation:

To determine whether each ordered pair is a solution to the system of equations:

7x - 4y = 8

y = -9x - 2

We will substitute the x and y values from each ordered pair into both equations.

For the ordered pair (0,-2), substitute x = 0 and y = -2:

7(0) - 4(-2) = 8 satisfies the first equation, and -2 = -9(0) - 2 satisfies the second equation, so (0,-2) is a solution.

Repeating this process for the other ordered pairs, (5,3), (-2,16), and (-4,-9), will reveal whether they satisfy both equations.

If both equations are satisfied by a particular ordered pair, then that ordered pair is a solution to the system of equations.

YOU CAN HAVE 4 MORE HOURS WITH THE PHOTO BOOTH

Step-by-step explanation:

500 IS FOR 2 HOURS SHE DONT WANT TO WASTE MORE THAN 700 SO ITS 50 DOLLARS FOR ANOTHER HOUR

500 + 50 IS 550 THATS ONE HOUR ADDED 550+50 = 600 THATS 2 HOURS 600 + 50=650 THATS 3 HOURS 650+50= 700 SHE GOT IT FOR 4 HOURS IN TOTAL SHE HAD IT FOR 6 HOURS COUNTING THE 2 HOURS FOR IT AT THE PARTY . PERIODDT.....

Cindy can rent the photo booth for a maximum of 4 additional hours beyond the first two hours included in the base fee, given her budget of $700.

The student is asking how many additional hours Cindy can rent a photo booth for her party, given her budget constraints. Initially, there is a $500 fee for two hours, and each additional hour costs $50. Cindy has a budget of $700 in total, which means she can spend $200 on additional hours beyond the first two hours included in the base fee. To calculate the maximum number of additional hours, we divide the additional budget ($200) by the cost per additional hour ($50).

So, the calculation is
$200 / $50 = 4 additional hours.

Cindy can thus rent the photo booth for a maximum of 4 additional hours without exceeding her budget of $700.

The original price of the shirt must be $15 if a 20% discount resulted in the final price becoming $12

The original price of the shirt is $15.

Discount refers to the condition of the price of a bond that is lower than the face value. The discount equals the difference between the price paid for and it’s par value.

Discount is a kind of reduction or deduction in the cost price of a product. It is mostly used in consumer transactions, where people are provided with discounts on various products. The discount rate is given in percentage.

Discount = Original price - Buying Price

Given,

Buying price of the shirt john bought = $12

Discount on shirt John bought = 20% of the original price

Let, the original price be x

then,

discount = 20% of x = 20x/100

Discount = Original price - Buying Price

20x/100 = x - $12

x = $12 + 20x/100

x = ($1200 + 20x)/100

100x = $1200 + 20x

80x =$1200

x = $1200/80

x = $15

Hence, the shirt cost $15 originally.

Answer:

4/15

Step-by-step explanation:

There are red, green and blue marbles in the bag.  The total of all the probabilities of selecting red, green and blue marbles is 1.00, or just 1.

So, to find the probability of selecting a blue marble, we add together 1/3 and 2/5 and subtract the total from 1:

1 - (1/3 + 2/5)

or:

1 - (5/15 + 6/15)

or:

1 - 11/15, or 4/15 (answer)

Final answer:

The probability of selecting a blue marble from the bag, given that reds have a probability of 1/3 and greens 2/5, is 4/15.

Explanation:

To find the probability of selecting a blue marble, you need to subtract the probability of selecting either a red or a green marble from 1, since the total probability must equal 1.

You are given that the probability of selecting a red marble is 1/3, and the probability of selecting a green marble is 2/5. To find the probability of selecting a blue marble, you can use the formula:

Probability of blue marble = 1 - (Probability of red marble + Probability of green marble).

Substituting the given probabilities, we get:

Probability of blue marble = 1 - (1/3 + 2/5)

Firstly, find a common denominator for the fractions, which is 15.

Probability of blue marble = 1 - (5/15 + 6/15)

Probability of blue marble = 1 - 11/15

Probability of blue marble = 15/15 - 11/15

Probability of blue marble = 4/15. Hence, the probability of selecting a blue marble is 4/15.

Then, a=-1 and b=-1

Step-by-step explanation:

We need to solve the following system of equations using the adition method:

2a+3b=-1       (i)

3a+5b=-2      (ii)

First, we multiply the equation (i) by -3 and the equation (ii) by 2, so we get:

-6a-9b=3

6a+10b=-4

Adding the two equations we have:

-6a-9b=3

6a+10b=-4

--------------------------

 0  + b = -1

Then b=-1. Now, let's substitute the value of b into equation (i):

2a+3b=-1

2a + 3(-1) = -1

2a -3 = -1

2a = 2

a = 1

Then, a=-1 and b=-1

Answer:

a = 1 and b= -1

Step-by-step explanation:

It is given two equations,

2a + 3b = -1  and

3a + 5b = -2  

To find the solution of given equations

Let, 2a + 3b = -1   ----(1)

3a + 5b = -2   ------(2)

(1) * -3 ⇒

-6a - 9b = 3    ----(3)

(2) * 2 ⇒

6a + 10b = -4   -----(4)

(3) + (4 )⇒

-6a - 9b = 3    ----(3)

6a + 10b = -4   -----(4)

  0 + b  = -1

(1) ⇒ 2a + 3b = -1  

2a + (3 * -1) = -1

2a = -1 + 3 = 2

a = 2/2 =1

Therefore, a = 1 and b = -1

Answer: Area of shape which is 15 cm is 312.5 square cm.

Step-by-step explanation:

Since we have given that

Area of shape of 12 cm = 200 sq. cm

We need to find the area of shape of 15 cm.

As we know the "Area similarity theorem" which states that ratio of areas of two similar shapes is equal to the square of ratio of corresponding sides.

So, it becomes,

[tex]\dfrac{12^2}{15^2}=\dfrac{200}{x}\\\\\dfrac{144}{225}=\dfrac{200}{x}\\\\144x=200\times 225\\\\144x=45000\\\\x=\dfrac{45000}{144}\\\\x=312.5\ cm^2[/tex]

So, Area of shape which is 15 cm is 312.5 square cm.

The area of shape B which is of 15 [tex]\text{cm}[/tex], is 312.5 [tex]\text{cm}^2[/tex].

Given information:

The two shapes A and B are given

The dimensions of shape A is 12 [tex]\text{cm}[/tex]

The area of the shape A is 200 [tex]\text{cm}^2[/tex]

Now, we need to calculate the area of the shape of 15 [tex]\text{cm}[/tex]

As we know that area will be square of the given values in the question.

So, according to the question:

[tex]\frac{A^2}{B^2} =\frac{200}{x}[/tex]

[tex]\frac{12^2}{15^2} =\frac{200}{x}\\\\\frac{144}{225}=\frac{200}{x} \\\\x=(200\times 225)/144\\\\x=312.5 \text{cm}^2[/tex]

Hence, the area of shape B which is of 15 cm, is 312.5 [tex]\text{cm}^2[/tex].

f(x) = x^2 - 3x

f(f(x)) = (x^2 - 3x)^2 - 3(x^2 - 3x)    (Replacing the x in f(x) by x^2 - 3x).

when f(f(x) = f(x):

(x^2 - 3x)^2 - 3(x^2 - 3x)  = x^2 - 3x

(x^2 - 3x)^2 - 4(x^2 - 3x) = 0
