Answer:

28

Length=2(x-1)

Width=5

Area=length*width = (2(x-1))(5) = (2x-2)(5) = 10x-10

29

His reasoning is illogical because whether or not an expression has a term that is being subtracted isn't relevant; technically there are an infinite amount of ways to represent a value. Plus you can just compute the expressions and see that they're equal:

6x-2x+4 = 4x+4

4(x-1) = 4x+4

30

The two expressions are equal because when you compute the expression 4(n+3)-(3+n) , you get 3n+9:

4(n+3)-(3+n) = 4n+12-3-n = 3n+9

31

The two expressions are equal because when you compute the expression 2(2n-1), you get 4n-2.

2(2n-1) = (2)(2n)+(2)(-1)=4n-2

32

5(g+14)=(5)(g)+(5)(14)=5g+70

The expressions aren't equal as 5(g+14) equates to 5g+70 and 5g+70≠5g+14.

Let Z={a,c,{a,b}}. What is |Z|?
Lina20 [59]

Z=\{a,c,\{a,b\}\}

\boxed{|Z|=3} (treat \{a,b\} as one element of Z)

The power set of Z is

\boxed{2^Z=\bigg\{\{\},\{a\},\{c\},\big\{\{a,b\}\big\},\{a,c\},\big\{a,\{a,b\}\big\},\big\{c,\{a,b\}\big\},\big\{a,c,\{a,b\}\big\}\bigg\}}

1. \{a,c\}\subseteq Z is true because both a\in Z and c\in Z.

2. a\in Z is true.

3. \{c\}\subseteq Z is true (same reason as part 1).

4. \{c\}\in Z is false because Z does not contain the set \{c\}, rather just the element c itself.

5. b\in Z is false because the element b on its own simply is not in Z. That b\in\{a,b\} does not mean b\in Z, but that b belongs to a subset of Z.

6. \{a,b\}\in Z is true.

25 Trent's watch runs at half the speed itshould. In other words, the hands on thewatch move only a half hour when an hourof tim
sergeinik [125]

Given that Trent's watch runs at half the speed it should run, this implies that

for every hour passed, his watch moves by half an hour.

Hence, for every half-hour passed, Trent's watch moves by 15 minutes.

Hence, when the real time is 10:30 am, Trent's watch will show 9:15 am.

PLEASE HELP! URGENT! Exponential function f is being represented by the table (photo attached) the function “g” is an exponentia
Y_Kistochka [10]

Answer:

C) Both functions are decreasing and both are positive on the interval (0;2)

Step-by-step explanation:

As known the exponent function has no minimum and has no maximum.

Otherwise exponent function can be only or increasing or decreasing for all x.

That means that in case y(x2)>y(x1) and  if x2>x1-  function is increasing.

That means that in case y(x2)<y(x1) and  if x2>x1-  function is decreasing.  

Lets check what is going on with the function f(x)

If x1=0        f(x1)=24

If x2=2        f(x2)=0

So    x2>x1 however f(x2)<f(x1)=> function is decreasing

Similarly g(x)

If x1=0   g(x1)=15

If x2=2   g(x2)=0

So x2>x1 however g(x2)<g(x1) => function is decreasing

So bothfunctions are decreasing.

Because f(x) is decreasing the function meaning with argument x1=0 has max in the interval x∈(0;2) And function meaning has the minimum if argument x2=2.   So the function F(x) in interval (0;2) is changing from 24 to 0 => is positive on the interval (0,2)

The same is with g(x) .  g(x) gonna be positive on the interval (0;2)

An Antique Collector want to know the age of a particular chair in a shop Statistical or not statistical
dmitriy555 [2]

Answer:

\boxed{\bold{Not \ Statistical}}

Step By Step Explanation:

Statistical: A survey, branch or mathematics consisting of data collection, organization, analysis, interpretation and presentation.

A statistical question deals with social problems, people, or something that must be studied and data gained. Statistical questions must have data sets and data gained. They also must have answers that vary from side to side or opinion to opinion, in order to be qualified as a 'statistical question'.

"<u><em>An Antique Collector wants to know the age or a particular chair in a shop</em></u>"

                                                V

Statistical                       Not Statistical

\boxed{\bold{>}} This is not a statistical question because there is no data that needs to be collected, no surveys that need to be filled out and no analysis, interpretation and presentation. The answer to this question does not vary. It is simply a fact.
