Step-by-step explanation:

The best describes the domain of the function is All the whole numbers greater than or equal to 0 and less than or equal to 7

A collection of facts, such as numbers, words, measurements, observations.

Discrete data is counted and can only take certain values - like whole numbers

e.g. the number of cars passing by a school.

Shoe size is an example of discrete data as size 6 and 7

have a meaning however size 6.2 does not.

Given:

A college student recorded his progress for a reading assignment at the end of each day for 7 days.

As, from the graph

domain = { x| 0, 1, 2, 3, 4, 5, 6, 7}

Them we can say that the domain is all the whole numbers greater than or equal to 0 and less than or equal to 7

Answer:

Option D

Step-by-step explanation:

Sales of Noralie's jewelry were on a decline for the first four months.

After April, the sales started improving.

Given the function to represent the sales:

[tex]y=\left \{ {{-x+8}\ if\ x<4 \atop {x} \ if\ x\geq 4} \right.[/tex]

To find:

The table from the answer options that represent the answer.

Solution:

From the options, it can be clearly seen that value of [tex]x[/tex] is 2, 4, 6, 8, 10, 12.

Let us put the values one by one and then check the value of [tex]y[/tex].

[tex]x = 2,\ y = -2+8 = -6\\x = 4\, y = x = 4\\x = 6,\ y = x = 6\\x = 8,\ y = x = 8\\x = 10,\ y = x = 10\\x = 12,\ y = x = 12[/tex]

Therefore, the answer table is:

[tex]\begin{center}\begin{tabular}{ c c}x & y \\ 2 & -6 \\ 4 & 4 \\ 6 & 6 \\ 8 & 8 \\ 10 & 10 \\ 12 & 12 \\\end{tabular}\end{center}[/tex]

Answer:

-1

Step-by-step explanation:

For piecewise functions, you should look at the range of values and see where the number you are looking for falls. In this case, -1 is included in the domain of the middle equation, so you will be using f(x) = x

Then, all you have to do is plug in -1 for x, so f(-1) = -1

The correct option is;

B. 10,600; 2,650; About 10,600 people visited the website in May. About 2,650 people visited the website in March

Step-by-step explanation:

The given parameters are;

The number of people that visit the website every month = 2 × The number of people that visited the website the previous month

The number of people that visit the website during May ≈ 10,600

The number of visitors of the website are given by the expression 10,600 × [tex]2^t[/tex]

For t = 0, we have;

The number of visitors of the website = 10,600 × 2⁰ = 10,600

For t = -2, we have;

The number of visitors of the website = 10,600 × 2⁻² = 2,650

Therefore, the website had about 10,650 visitors in May and about 2,650 visitors in 2 months earlier in March.

Answer:

  80.5%

Step-by-step explanation:

The percentage change can be found from ...

  percent change = (change)/(original value) × 100%

  = (370000-205000)/205000 × 100%

  = 165/205 × 100%

  ≈ 80.49%

The change in the price of the house was about 80.5%.

Answer:

2.03403 * 10^2

Step-by-step explanation:

Here, we want to write the given number in standard form

Firstly, we need to write the number in the normal form;

Mathematically, that will be;

203.403

Now, to write in standard form, we move the zero to the back of the first non-zero digit which is 2

What we have in this case will be:

2.03403

How many times did we move the decimal point?

The decimal point was moved two times

So, what we have is that the number two will become a power of 10

So therefore, we have it that;

2.03403 * 10^2

Kindly note that if the movement was to the left, the power becomes a negative number on 10

Step-by-step explanation:

Answer:

Step-by-step explanation:

(C). 4a³ + 24ab² - 25b³

[tex](2x - \frac{1}{3} ) - ( \frac{2}{x} + 1)[/tex]

[tex]2x - \frac{1}{3} - \frac{2}{x} + 1[/tex]

[tex](2x - \frac{2}{x} ) + ( - \frac{1}{3} + 1)[/tex]

[tex] (\frac{2 {x}^{2} }{x} - \frac{2}{x} ) + ( \frac{ - 1}{3} + \frac{3}{3} )[/tex]

[tex] \frac{2 {x}^{2} - 2 }{x} + \frac{ - 2}{3} [/tex]

We want to write the given expression as a single fraction. We will get the fraction:

[tex]\frac{6*x^2 - 4*x - 6}{3*x}[/tex]

So we start with the expression:

[tex](2*x - \frac{1}{3}) - (\frac{2}{x} + 1)[/tex]

First, let's rewrite each of these parenthesis as fractions, we need to have the same denominator in all the terms, then in the first one we can multiply and divide by 3 (and in the second one we can do the same but with x) so we get:

[tex](\frac{3}{3} *2*x - \frac{1}{3}) - (\frac{2}{x} + 1*\frac{x}{x} )\\\\(\frac{6*x}{3} - \frac{1}{3}) - (\frac{2}{x} + \frac{x}{x} )\\\\\frac{6*x - 1}{3} - \frac{2 + x}{x}[/tex]

Now we must multiply and divide the left term by x, and the right term by 3, so we get:

[tex]\frac{x}{x} \frac{6*x - 1}{3} - \frac{2 + x}{x}*\frac{3}{3} \\\\\frac{6*x^2 - x}{3*x} - \frac{6 + 3x}{3*x} = \frac{6*x^2 - x - 3x - 6}{3*x}\\\\\frac{6*x^2 - 4*x - 6}{3*x}[/tex]

This is the fraction in its simplest form.

Answer:

Step-by-step explanation:

length = l  ;width = w

Perimeter of rectangle = sum of all sides

                                      =  l + w + l +w
