River otters can be found all across the United States except for in the desert and the Florida Keys. They live in both freshwater and slightly salty, brackish habitats. As their name suggests, they inhabit rivers, but they also inhabit lakes, as well. River otters choose their habitat based on how much food and shelter they can find. As a result, their habitat can change depending on the season. For example, they will move from temporarily flooded marshes to cypress swamps that have permanent ponds. They make their dens in bank burrows, under trees and stumps, or in thick vegetation.

An image of what they look like is attached.

Gautrain is an 80-kilometre (50 mi) commuter rail system in Gauteng, South Africa, which links Johannesburg, Pretoria, Ekhuruleni and O. R. Tambo International Airport.

Gautrain currently offers two distinct train services: an Airport Service linking Sandton and Marlboro to the OR Tambo International Airport and a Commuter Service linking Rhodesfield, Marlboro, and Sandton (east-west link) and Park, Rosebank, Sandton, Midrand, Centurion, Pretoria Central and Hatfield (north-south link)
Gautrain train service operates across Johannesburg, Pretoria and Ekurhuleni and also connects to the OR Tambo International Airport.
Gautrain bus service offers over twenty bus routes that provide safe and efficient access to our train stations.
Parking and drop-off facilities are available at all stations except for the OR Tambo International Airport Station.

Gautrain fares are calculated according to your time of travel. These times are divided as follows:
High-Peak fares are applied when you access the Gautrain system on weekdays between 06h30 and 07h30 and when travelling in the direction indicated in the fare table available here
Peak fares are applied when you access the Gautrain system between 06h00 and 08h30 (unless High-Peak applies), between 15h30 and 18h00 on weekdays and all day on weekends and public holidays.
Off-Peak fares are applied when you access the Gautrain system before 06h00, between 08h30 and 15h30 or after 18h00 on weekdays.

The Gautrain's bus and train services operate daily between 05h30am and 08:30pm. Scheduled departures can be accessed using the Gautrain app, at any Gautrain station or here.

The train schedule differs in peak and off-peak periods as follows:
During Peak Periods trains depart at 10 minute intervals.
During the Off-Peak period trains depart at 20 minute intervals.
On weekends and public holidays, trains depart at 30 minute intervals.

Gautrain buses depart from stations and end stops at scheduled times. Whilst every effort is made to ensure that this service operates to schedule, the Gautrain buses make use of public roads and may be delayed during road incidents and traffic congestion. Gautrain bus routes are available here, and the Gautrain app allows you to track your bus in real-time.

To access the Gautrain train or bus service, each passenger is required to possess a Gautrain Card with a minimum value of R25 loaded onto it. Gautrain Cards can be re-used by simply loading value as and when needed. The same Gautrain Card must be used to tag into and out of the stations, bus and parking. This will ensure that any applicable discounts are automatically calculated and deducted from your fare. Failure to tag out of the service may result in a penalty fee being applied.
Gautrain Cards can be purchased at any Gautrain station using either the Ticket Vending Machines (TVM) or the Ticket Office. The TVMs are similar to the ATM bank terminal and accepts cash and bank cards. Gautrain Cards can also be purchased from vending machines conveniently located along certain Gautrain bus routes. For more details of these locations, please visit this page.

Something to help with your understanding of the answer and the question itself:

The built environment provides the setting and backdrop by which we live our lives, and
impacts on our senses, our emotions, participation in physical activity and community life,
our sense of community, and general wellbeing. Meanings are generated by buildings and
spaces, which we 'read' as we pass through them. Places are created and shaped by those in
control of resources and with certain interests, which affects our degree of access to, and the
way we use, those spaces.
People living in particular localities may be prone to particular diseases if the aetiology of
that disease is located in the environments in which they live. Although disease and illness
may be caused by a virus or toxic substance, it may be social institutions and practices which
actually create the circumstances in which people come into contact with these disease-
inducing agents. Places have certain environmental characteristics, such as the availability of
healthy foods, health-affirming services, community norms and so on, which influence health
behaviour. Health disadvantage is exacerbated in socially and economically disadvantaged
settings. Health promotion strategies need to take into consideration the impact of social
structure, place and time on people's health-related knowledge, attitudes and behaviours.
People with disabilities are not only marginalised by social and political structures, but these
same structures are reflected in the built environment. These built forms serve to reinforce
the physical and psychosocial isolation associated with their disability.

The word image is an unbound morpheme, not a bound morpheme, because it is a word by itself. In any language,a morpheme is a unit of meaning. A word is an unbound morpheme because it is a unit of meaning when it stands alone, not bound to anything else. Image is a morpheme in "imagination," but, because image is a word in itself, image is an unbound morpheme, rather than a bound morpheme.
Thanks to Charles Cairns in comments, I have some example of bound morphemes.
Any prefix or suffix that is not a word in itself is a bound morpheme. That would include terms like infra (used in infrastructure and infrared, but not a word in itself). Also suffixes, like -s and -es to make a word plural. I asked Charles for some word roots that were bound morphemes, and he suggested pant- as in pants and scissor- as in scissors.
Original example, questioned by linguist Charles Cairns in comments.
In contrast, in English, -struct- is a bound morpheme. It is not a word in itself. Yet it can be a suffix, as in instruct, or a prefix, as in structure. Or it can be a root, as in destructive. A unit of meaning that is not a word in itself, but is any or all of these: prefix, suffix, infix, or root is a bound morpheme.
Charles challenged this because most or all the words that contain -struct- are from the Latin, so it may be that it is a Latin root, but, as new words are not developing in English, not a bound morpheme in English. As he is the expert, I bow to his knowledge. At the same time, I wonder about words like reconstruction, deconstruction, and infrastructure. As I suspect some of these words were created in English, one might make a case for -struct- being a bound morpheme with more and more prefixes and suffixes being added on.
For more, see Bound and unbound morphemes - Wikipedia.

Fixya maths 4 indices

Indices n surds

Hai again your support helps me alot can you please differentiate for me between the following -6to the power 2 and -6 to the power 2,& 2 to the power -3 + 1/3 to the power-2
I need a clarity how to convert these exponents to fractions
Posted by Ncwana Noziphiwo on Apr 03, 2018


-62 means a number multiplied by itself twice
So in this case it is -6 x -6 = 36 - since -x- = +
If this was -6-2 the negative power means it's a fractional indice so first make it look like a fraction
1/-62 now it looks like a fraction (inverse) and the power mow looks like a normal square
Coz its still a negative number -6 x -6 = 36
So the answer is now 1/36

So when it is a minus power, first turn it into a fraction, then calculate as normal
Note: every number has a sign, it is either + or minus.
By convention, we always assume it is a plus unless stated otherwise.
To make sure u remember this fact put a plus sign in front of every number if no sign is showing
You can start with buses the 27 bus is +27
Its like if u say u have a car, what u really mean is you have 1 car. But u drop the 1 coz everyone takes for granted u meant 1 car, 1 house, 1 friend etc
Every power we assume its + unless otherwise stated.
So when a minus is put in front of the power, its saying make it a fraction first!
Maths is a game and games have rules.
This rule is a minus in front of power (indice) change to fraction form first!
So if it is 2-3 - the power -3 is saying turn it into a fraction first so
1/23 = 1/ 2x2x2 = 1/8
If it had of been 23 notice how no signs shown because we take for granted they r all +
Let's show them
+2+3 since it's a plus 3 we don't need to change it to a fraction and since it is a plus 2
We have +2 x + 2 x +2 and a +x+ x+ = +
2x2x2 = 8
Its easier to just do 23 = multiply the 2 by itself 3 times
2x2x2 = 8
When doing fractions of any type I prefer showing them as being more obviously top/bottom

Format and for that free hand is easier as typing is hard...lol
Numerator Denominator
When using a number that's a fraction it is better tro enclose it in brackets
As every indice is of the form - numberpower
The number can just as easily be a fractional number like a 1/3
So (1/3)2 is a third multiplied by itself
1/3 x 1/3 = 1x1/3x3 = 1/9
If it was (1/3)-2 then first u must get rid of the minus power by turning it into a fraction
1/1/3 x 1/3
And 1 divided by a ninth =
1 to be cont - tired..lol

5x + 7 = 45
5x = 45 -7
5x = 38
X = 38/5 = 7 3/5 or in decimal
X = 7.6
Or this could be a straight line equation of y = mx + c
Were y = 45 m = 5 = gradient of 5. Through the point of origin c = 7 at x =0

Depends. If you are a big company with a lot of relative economic power, you may be able to get away with this. For example, if you are the size of Walmart, and your suppliers ask you to pay you in 90 days (more typical in Europe than North America) and you pay your suppliers in 257 days, you have done well for your cash flow. However, when you need some help from your supplier, it may not be there. Also, the supplier may just decide not to deal with you anymore. We had a very large customer that did this to the company I was working for and my recommendation was for them to pay us sooner or drop the client, as we were losing money on every transaction because of their delay in paying us.

Good luck,

I interpreted the question as:

(x-2)/(4-x) + 2/3 = (x-2)/12 or

(x-2) 2 (x-2)
------ + --- = -----
(4-x) 3 12

Now to find a common denominator.

I factor all the terms and see what is common, so it can be eliminated to leave the lowest common denominator.

(4 - x) - prime - cannot be factored

3 - prime - cannot be factored

12 - 4 x 3

What is common in the above? The 3, so we can eliminate one 3.

Common denominator - (4 -x) (3)(4)

So, we must multiply the numerator and denominator of the first term by 12 (3 x 4).

The next term's numerator and denominator must be multiplied by 4(4-x).

The term on the right of the equals sign must have the numerator and denominator multiplied by (4-x).

Good luck.

If you need more assistance, post again.
