A horizontal stretch by a factor of 4 means that each point on a graph is moved away from the y-axis by a factor of 4. Mathematically, if you have a function ( f(x) ), the horizontally stretched function is represented as ( f\left(\frac{x}{4}\right) ). This transformation results in the graph appearing wider, as it takes longer for the function to reach the same y-values compared to the original function.

One factor that is not necessary for an ecosystem to be self-sustaining is the presence of a specific keystone species. While keystone species can play important roles in maintaining ecological balance, ecosystems can still function and sustain themselves through other species and interactions. Self-sustainability primarily relies on energy flow, nutrient cycling, and biodiversity, rather than the presence of any single species.

The stretcher bond is a practical work solution in masonry that involves laying bricks in a staggered pattern, providing both structural stability and aesthetic appeal.

The factors of -60 that add up to 17 are 20 and -3. When you multiply 20 and -3, you get -60, and when you add them together, you get 17. Therefore, the pair of factors you are looking for is 20 and -3.

The weather is a factor that is entirely out of human control. Despite advancements in technology and forecasting, natural phenomena such as storms, temperature changes, and climate patterns cannot be influenced or altered by human actions. This unpredictability can significantly impact various aspects of life, including agriculture, travel, and disaster preparedness. Ultimately, while we can prepare for and respond to weather events, we cannot change or control them.

The amount of runoff is influenced by several factors, including:

1. Rainfall Intensity and Duration: Heavy and prolonged rainfall increases runoff as the ground becomes saturated.
2. Soil Type: Different soils absorb water at different rates; sandy soils allow for more infiltration, while clay soils can lead to more runoff.
3. Land Use and Vegetation: Urban areas with impervious surfaces generate more runoff compared to forested or vegetated areas that can absorb water.
4. Topography: Steep slopes facilitate faster runoff, while flat areas may promote water retention.
5. Ground Saturation Levels: If the soil is already saturated from previous precipitation, any additional rainfall will result in increased runoff.
