Answer:
2√7
Step-by-step explanation:
Mathematically, the equation of a circle can be represented by;
(x-h)^2 + (y-k)^2 = r^2
where (h,k) = center and r = radius
Applying this to the question, we can see that the length of the radius of the circle is √7
The diameter is always twice the radius
Thus, the diameter KL = 2 * √7 = 2√7
Two six-sided fair dice are rolled simultaneously.... 6 and the sum of the two numbers is an odd number is mathematically given as
x=7/10

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>
Answer:
ok and whats the question
Step-by-step explanation:
Answer:
a = - 1.1
Step-by-step explanation:
The condition for a single variable function f(x) to be decreasing is f'(x) < 0.
f(x) = 4/x^2 - 6x + 9
Then, differentiating with respect to x on both sides we get,
f(x) = 4(-2)(1/x^3) - 6 < 0
-8/x^3 - 6 < 0
8/x^3 + 6 > 0
{Dividing both sides with - 1 and hence the inequality sign changes}
8/x^3 > -6
8 > - 6x³ {Multiplying both sides with x³}
6x³ > - 8 {Interchanging the sides}
x^3 > -8/6
⇒ x > - 1.1
So, a = - 1.1
