Option D: A(n) = a + (n – 1) d

Solution:

To identify the formula for finding the nth term of an arithmetic sequence.

Let a be the first term.

d be the common difference of the each term.

n be the term of the number.

A(n) be the nth term of the arithmetic sequence.

Arithmetic formula:

A(n) = a + (n – 1) d

Example: 1, 4, 7, 10, 13, 16, 19, ...

This is a arithmetic sequence.

a = 1, d = 4 – 1 = 3.

To find the 5th term:

Substitute this in the above formula, we get

A(n) = a + (n – 1) d

A(5) = 1 + (5 – 1) 3

       = 1 + 4(3)

       = 1 + 12

A(5) = 13

In the given sequence 5th term is 13.

Hence Option D is the correct answer.

A(n) = a + (n – 1) d

Answer:

A(n) = a + (n - 1)d

Answer:

A. Only Khaled

Step-by-step explanation:

The teachers equation is:

[tex]-10x-7y=5[/tex]

[tex]12x-8y=-4[/tex]

If a row operation on the teacher's equation results in any of the system of the students' equation then the two systems are equivalent and will have the same solution.

For instance:

Let's maintain the bottom equation and add both equation to replace the top equation:

[tex]-10x+12x-7y-8y=5+-4\\12x-8y=-4[/tex]

This results in Khaled's equation:

[tex]2x-15y=1\\12x-8y=-4[/tex]

On the other hand we cannot perform a row operation to obtain Miku's equation

Answer:

The cup can hold 235.5 cubic cm of popcorn.

Step-by-step explanation:

Given:

A cone shaped popcorn cup has a radius of 5 cm and a height of 9cm.

Use 3.14 as an approximation for pi.

Now, to find cubic cm of popcorn the cup can hold.

Radius ( r ) = 5 cm.

Height ( h ) = 9 cm.

π = 3.14 ( as per question ).

So, to get the cubic cm of popcorn the cup can hold we put formula of volume:

[tex]Volume = \pi r^2\frac{h}{3}[/tex]

[tex]Volume=3.14\times 5^2\times \frac{9}{3}[/tex]

[tex]Volume=3.14\times 25\times 3[/tex]

[tex]Volume=235.5\ cubic\ cm.[/tex]

Therefore, the cup can hold 235.5 cubic cm of popcorn.

The transformer is 27.5 ft above the ground.

Solution:

The given image is like a triangle.

Angle 'L' represents the triangle is right triangle.

Use Pythagoras theorem to find the answer.

Base of the triangle = 12 ft

Hypotenuse of the triangle = 30 ft

Height of the triangle = x

Using Pythagoras theorem,

[tex]\text{Base} $^{2}+$ Height $^{2}=$ Hypotenuse $^{2}$[/tex]

[tex]12^2+x^2=30^2[/tex]

[tex]144+x^2=900[/tex]

Subtract 144  on both sides of the equation.

[tex]x^2=900-144[/tex]

[tex]x^2=756[/tex]

Taking square root on both sides.

[tex]x=27.5[/tex]

Hence the transformer is 27.5 ft above the ground.

Answer:

Step-by-step explanation:

we know that

The area of a square is equal to

[tex]A=b^2[/tex]

where

It is a function

A function is a relation between two sets that associates to every element of a first, called set A, one and only one element of the second set, called set B. In other words, we can't have any element of the set A assigned to more than one element in the set B. Put another way, we can't have repeated elements of the first set. In this problem we have a relation given by the table:

[tex]\begin{array}{cc}x & y\\5 & -2\\7 & -2\\9 & -2\end{array}[/tex]

So the assignation is as follows:

[tex]5 \rightarrow -2 \\ \\ 7 \rightarrow -2 \\ \\ 9 \rightarrow-2[/tex]

As you can see every element of the set A (set x) is assigned to the same element in the set B (set y) but we have no repeated element in the first set, so this is a function.

Answer:  [tex]average\ rate\ of\ change\approx-3[/tex]

Step-by-step explanation:

For this exercise you need to use the following formula:

[tex]average\ rate\ of\ change=\frac{f(b)-f(a)}{b-a}[/tex]

You need to find the average rate of change of the given function g(x) over the following interval:

 [tex][-1,2][/tex]

So, you can see in the table that the point whose x-coordinate is -1, is:

[tex](-1,5)[/tex]

And the point whose x-coordinate is 2, is:

[tex](2,-3)[/tex]

Knowing this, let be:

Step-by-step explanation:

To find the number of blue fish, we set up an equation based on the given information, solving which indicates there are 18 blue fish in the tank (option A).

The question is a word problem asking to find out the number of blue fish in a tank given the total number of fish and the relationships between the counts of different colored fish. We can set up algebraic expressions to solve for the number of blue fish. Let the number of blue fish be represented by x. According to the problem, there are six more yellow fish than blue, which we can express as x + 6. There are four fewer black fish than blue, which we can say is x - 4. The total number of fish is given as 56.

So, the equation we can set up is:

x + (x + 6) + (x - 4) = 56

Simplifying the equation, we get:

3x + 2 = 56

Solving for x, we subtract 2 from both sides to get:

3x = 54

And then divide by 3:

x = 18

Thus, there are 18 blue fish in the tank, which corresponds to option A.

Answer:

10 boxes in the top row.

192 boxes in entire display.

Step-by-step explanation:

Let n be the number of rows.

Given:

Total number of rows = 8

Boxes in bottom row = 38

And each row has four fewer boxes than the row below it.

Solution:

Part A:

We know that the bottom row has 38 boxes and each row has four fewer boxes than the row below it.

Using below function for determining the number of boxes in each rows.

[tex]f(n)=38-(8-n)4[/tex]

Where:

n = Number of row.

We need to find the boxes in the first row.

So, substitute n = 1 in above function.

[tex]f(1)=38-(8-1)4[/tex]

[tex]f(1)=38-7\times 4[/tex]

[tex]f(1)=38-28[/tex]

[tex]f(1)=10[/tex]

Therefore, 10 boxes in the top row.

Part B:

Total boxes in the entire display.

Using formula as given below to determine the sum of the boxes in entire display.

[tex]S_{n} = \frac{n}{2}(f(1)+f(n))[/tex]

Substitute n = 8, f(1) = 10 and f(8) = 38 in the above equation.

[tex]S_{8} = \frac{8}{2}(10+38)[/tex]

[tex]S_{8} = 4(48)[/tex]

[tex]S_{8} = 4\times 48[/tex]

[tex]S_{8} = 192\ boxes[/tex]

Therefore, 192 boxes in the entire display.
