Answer:

In a linear equation, like the ones in the graphs, the slope is equivalent to the rate of change. And we know that speed is defined as the rate of the position, thus the slope of these lines is exactly equal to the speed.

From this, we will see that the correct option is D.

Knowing this, two runners will have exactly the same speed if and only if both slopes (one for each runner) are exactly equal. This means that we will see two parallel lines.

This makes a lot of sense, because if they run at the same speed, then they will never meet (like two parallel lines), instead if they run at different speeds and the one that is behind runs faster, at some given point the one that goes last will reach the other, and in this point we would see that the lines intersect in the graph (like in options A, B, and C).

So from this we already can see the correct option, it is the graph with the two parallel lines, the graph D.

Celia's impact on early intervention success could be determined through:
Kaylis [27]

The correct answer is experimental research. There are few successful early interventions on a meaningful scale, seemingly due to a lack of learning and information sharing across local authority areas, and the failure to robustly evaluate many government and charity interventions. Expert interviews suggest that practice varies significantly by local authority area, and there is a need to identify, evaluate and scale-up interventions that work. Experts identified three main areas of early intervention to improve outcomes for children in care: 1. Supporting care leavers, including through employability and accommodation support. 2. Raising educational attainment. 3. Mental health and emotional wellbeing support. Supporting the transition out of care is the area at which most initiatives are targeted. There is a need for more upstream support to contribute to improving outcomes for care leavers, for example, supporting improved educational attainment.

AP human geography
sweet [91]

Answer:

In my personal opinion, the Quebecois form a different historical nationality from that of the Anglo-Canadians, fundamentally because they come from different historical contexts, and have different cultures, languages and even religions.

Thus, the Quebecois come from the first French settlers in Canada, they speak French and are mostly Catholic, while the Anglo-Canadians were arriving later, they speak English and are mostly Protestant.

Therefore, these differences mean that both groups, although they coexist in harmony, can be considered as different nationalities within the same country.

I believe the answer is:  are more likely to read your message than academic audiences.

People with business communication background are trained to interpret underlying message that come from various sources or behaviour. Academic audiences on the other hand, tend to only be able to read a certain message after its being constructed for common consumption (such as books)
