The rang of an inverse function is the domain of the normal function
So you just gotta find the domain of that which is x is greater than or equal to 0

2, 6, 10, 15, ...<br><br> O Arithmetic<br> O Geometric<br> O Neither<br> 
natima [27]

Given:

The sequence is:

2, 6, 10, 15,...

To find:

Whether the given sequence is Arithmetic, Geometric, Neither.

Solution:

We have,

2, 6, 10, 15,...

Different between consecutive terms are:

6-2=4

10-6=4

15-10=5

Since 4\neq 5, therefore the given sequence has no common difference. It means it is not an arithmetic sequence.

Ratio of consecutive terms are:

\dfrac{6}{2}=3

\dfrac{10}{6}=\dfrac{5}{3}

Since 3\neq \dfrac{5}{3}, therefore the given sequence has no common ratio. It means it is not a geometric sequence.

Since the given sequence is neither arithmetic nor geometric, therefore the correct option is C.

A person trying to gain access to a bank vault must pass through a series of three security doors. If an attempt to pass through
ExtremeBDS [4]

Answer:

C) S = {F, PF, PPF, PPP}

Step-by-step explanation:

For this case, we know that a person is trying to gain access to a bank vault and needs to go through 3 security doors, and we know that if the person does not pass a door, then he/she has no other attempts. We denote P= Successful pass , F= Failed pass

And we are interested on the sample space, we need to remember that the sample is the set with all the possible values for an experiment.

For this case the person can fail at the 1,2 or 3 try

For the case that fails at the 1 try we have F

For the case that fails at the 2 try we have PF

For the case that fails at the 3 try we have PPF

And the last option is that the person not fails at any try and we have PPP

So then the sample space would be given by:

C) S = {F, PF, PPF, PPP}

"Dimensional analysis" is the primary way to make conversions between any units.  Some have trouble because they fail to make it an important point to label units, but labeling units correctly makes tracking and making any conversion very simple...The process and thinking is that you want to cancel out units that you don't need in the solutions...

(198ft/s)(12in/ft)(2.54cm/in)(m/100cm)=60.3504m/s  (and that is exact)

d=5s(60.3504m/s)=301.752m

ugh...assume that a meter equals 3.3 feet and do not round your answers???
really?  These people are idiots when there is an exact conversion.  What is the point of not rounding when you are using a horrible approximation?  :D

(198ft/s)(m/3.3ft)=60m/s

d=5s(60m/s)=300m
