Answer:
Step-by-step explanation:
Given function:
where:
- h = height (in feet)
- t = times (in seconds)
Rewrite in the form 
The quickest way to do this is to expand and compare coefficients with the original function.
Comparing coefficients with
Therefore, substituting the found values into the equation:
Answer:
Step-by-step explanation:
Answer: k < 3
Step-by-step explanation: Just like any of your two-step equations, in this inequality, start by isolating the k term which in this case is 5k by subtracting 3 from both sides. That leaves you with 5k < 15.
To get <em>k</em> by itself, divide both sides by 5 and <em>k < 3</em>.
Answer:
<em>The food chain showing seven organisms can be drawn as follows:
</em>
<em>
</em>
<em>Plants → grasshoppers → mice → frog → snakes→ eagles → decomposers
</em>
<em>
</em>
<em>The plants are the primary source of food in a food chain or a food web. The animals which feed on plants will be termed as herbivores or primary consumers like the grasshopper. The organisms feeding on primary consumers will be the secondary consumers like mice.
</em>
<em>
</em>
<em>An energy pyramid for three of the organisms can be shown as follows:
</em>
<em>
</em>
<em> mice (10 kilocalories)
</em>
<em>
</em>
<em> ↑
</em>
<em>
</em>
<em> Grasshoppers (100 kilocalories)
</em>
<em>
</em>
<em> ↑
</em>
<em>
</em>
<em> Plants ( 1000 kilocalories)
</em>
<em>
</em>
<em>As the energy pyramid shows, only about 10% of the energy travels from one trophic level to another.</em>
