The diameter of a table tennis ball is millimeters. What is the approximate surface area of a table tennis ball?

**Answer:**

since there is no value for the dimensions of the tennis ball. The tennis ball is a sphere with a Surface Area 4pir²

how would I graph this correctly?

Answer:

You would shade the fourth quadrant (bottom right).

Step-by-step explanation:

Due to the domain and range sets, you're given the facts that x must be greater than or equal to 0, but y is less than or equal to zero. This gives you what quadrant the graph should be in. Since you're not given an equation to follow like y=ax+b, then I can not say that this will give you a line.

The line (y-1)=(2/3)(x+1) contains point (a,-3).

What is the value of a? Show

your work.

**Answer:**

-7

**Step-by-step explanation:**

The line (y-1)=(2/3)(x+1) contains point (a,-3)

=> (-3-1) = (⅔)(a+1)

-4 = (⅔)(a+1(

(a+1)= -4 ÷ ⅔

a + 1 = -4 × 3/2

a+ 1 = -6

a = -6-1

**a**** ****=**** ****-****7**

The **value **of 'a' will be;

⇒ a = - 7.

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The **equation of line** is,

⇒ (y - 1) = (2/3) (x + 1)

And, The point on the line = (a, - 3)

Now,

Since, The **point** on the line = (a, - 3)

Hence, It satisfy the equation of line.

**Substitute **x = a and y = - 3, we get;

⇒ (y - 1) = (2/3) (x + 1)

⇒ (- 3 - 1) = (2/3) (a + 1)

⇒ - 4 × 3 = 2a + 2

⇒ - 12 - 2 = 2a

⇒ 2a = - 14

⇒ a = - 7

Thus, The **value **of a = - 7

**Patterns **are **set of rules **that **guide **the **creation of a dataset**. The observation from the first three designs are as follows:

The pattern

The **first three design **show that, as the **design number increases **(i.e. 1, 2, 3), the **number of tiles **used **also increases **(i.e. 7, 12, 19)

The expressions for the number of tiles

The **design number **and the **number of tiles **is represented as follows

[tex]1 \to 7[/tex]

[tex]2 \to 12[/tex]

[tex]3 \to 19[/tex]

From the **designs**, we observe that some **tiles are at the middle**, while **other tiles are at the sides**.

**Design 1 **has **1 tile **at the **center **and **6 tiles **at **either sides.**

So, we have:

[tex]1 \to 1 + 6[/tex]

[tex]2 \to 4 + 8[/tex]

[tex]3 \to 9 + 10[/tex]

Expand

[tex]1 \to 1^2 + 6 \to 1^2 + 2 \times 3 \to 1^2 + 2 \times (1 + 2)[/tex]

[tex]2 \to 2^2 + 8 \to 2^2 + 2 \times 4 \to 2^2 + 2 \times (2 + 2)[/tex]

[tex]3 \to 3^2 + 10 \to 3^2 + 2 \times 5 \to 3^2 + 2 \times (3 + 2)[/tex]

Notice the **pattern,**

The **number of tiles **in **design n** will be:

[tex]Tiles = n^2 + 2 \times (n + 2)[/tex]

Open bracket

[tex]Tiles = n^2 + 2n + 4[/tex]

Hence, the **expressions **for **number of tiles **in **design n **are:

[tex]n^2 + 2(n + 2)[/tex] and [tex]n^2 + 2n + 4[/tex]

Technology to prove that both expressions are equivalent

To prove that [tex]n^2 + 2(n + 2)[/tex] and [tex]n^2 + 2n + 4[/tex] are **equivalent using technology, **the **graphs **of [tex]n^2 + 2(n + 2)[/tex] and [tex]n^2 + 2n + 4[/tex] can be **plotted **and then **compared**

The table and graph for the first 6 designs

The **table entry **for the first **6 designs **is calculated as follows:

[tex]n = 1\ \ \ \ \ Tiles = 1^2 + 2 \times 1 + 4 = 7[/tex]

[tex]n = 2\ \ \ \ \ Tiles = 2^2 + 2 \times 2 + 4 = 12[/tex]

[tex]n = 3\ \ \ \ \ Tiles = 3^2 + 2 \times 3 + 4 = 19[/tex]

[tex]n = 4\ \ \ \ \ Tiles = 4^2 + 2 \times 4 + 4 = 28[/tex]

[tex]n = 5\ \ \ \ \ Tiles = 5^2 + 2 \times 5 + 4 = 39[/tex]

[tex]n = 6\ \ \ \ \ Tiles = 6^2 + 2 \times 6 + 4 = 52[/tex]

So, we have:

[tex]\begin{array}{cc}Design & {Tiles} & {1} & {7} & {2} & {12} & 3 & {19} & {4} & {28} & {5} & {39}& {6} & {52} \ \end{array}[/tex]

We have:

[tex]Tiles = n^2 + 2n + 4[/tex]

The largest design that an empty sign of 10ft by 12ft can contain.

From the first three designs:

The number of tiles on a complete row and column are always the same.

Design 1 has 3 tiles in its complete row and column

Design 2 has 4 tiles in its complete row and column

Design 3 has 5 tiles in its complete row and column

The relationship between the **design number (d)** and the **number of complete tiles (t)** is:

[tex]d = t - 2[/tex]

For the **10ft by 12ft empty sign**

[tex]t = 10[/tex] because [tex]10 < 12[/tex]

So, we have:

[tex]d = t - 2[/tex]

[tex]d = 10 - 2[/tex]

[tex]d = 8[/tex]

To get to 49 by squaring, you need to square 7. Since x can only be negative, you need to get to -7.

**-11 + 4 = -7**

**(-7)^2 = 49**

To get to 49 by squaring, you need to square 7. Since x can only be negative, you need to get to -7.

Is the set of real numbers closed under addition? Explain why or why not. If it is not closed, give an example

**Answer: Yes, the set of real numbers is closed under addition.**

Explanation:

Let x and y be two real numbers. Their sum x+y is some other real number. This is what it means when we say the set of real numbers is closed under addition. Taking any two numbers and adding them will get us some other real number.

There is no way to have x+y be nonreal while x,y are both real.

Joanne a total score for a round of darts was -42 she had thrown 6 darts and scored the same each throw How many points did Joanne score on each throw

**Answer:**

7

**Step-by-step explanation:**

**Answer:**

7

**Step-by-step explanation:**

Ok, so we know 42 is the number of points added up, and we know that she threw 6 darts all scoring the same. Now, all we have to do is figure out what number(for example x) multiplied by 6 equals 42. Or in the form of an equation:

6x = 42

Now, to finish the equation, all we have to do is divide:

6x/6 = 42/6

42/6 = 7

a.) The median player salary for the New York Yankees was $1.5 million in 2007 and $1.7 million in 2013. Write a linear equation giving the median salary y in terms of the year x. (Let y be in millions of dollars and let

x = 7

represent 2007.)

b.) Use the equation to predict the median salary in 2048. (Round your answer to one decimal place.)

$ million

A general** linear equation** is given by:

[tex]y = a*x + b[/tex]

Where a is the **slope** and b is the** y-intercept.**

Here we will find that the **linear equation** that represents the situation is

[tex]y = 0.033*x + 1.269[/tex]

And we can expect that the median salary in 2048 is** **$2.853 million

If the** line **passes through the points (x₁, y₁) and (x₂, y₂) then the** slope **can be written as:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Here we know that:

in 2007 (x = 7) the median player salary was y = $1.5 million

in 2013 (x = 13) the median player salary was y = $1.7 million.

Then we have two points that we can write as:

(7, 1.5)

(13, 1.7)

Note that the y-value is in millions.

Then the **slope **of the** linear equation **will be:

[tex]a = \frac{1.7 - 1.5}{13 - 7} = 0.033[/tex]

So the** linear equation **is something like:

[tex]y = 0.033*x + b[/tex]

To find the value of b, remember the point (7, 1.5), this means that when we have x = 7, we also have y = 1.5, then we can replace these in the above equation:

[tex]1.5 = 0.033*7 + b\\\\1.5 - 0.033*7 = b = 1.269[/tex]

Then the **linear equation** is:

[tex]y = 0.033*x + 1.269[/tex]

b) Now we want to predict the median salary in 2048. For 2048 the x-value is x = 48

So we just need to evaluate this in the **linear equation:**

[tex]y = 0.033*48 + 1.269 = 2.853[/tex]

Then the median salary in 2048 will be $2.853 million
