We need to show that y = x/(x + c) is a solution of dy/dx = (y - y^2)/x. Then,
<span>dy/dx = ((x + c) * 1 - x * 1)/(x + c)^2 </span>
<span>= (x + c - x)/(x + c)^2 </span>
<span>= c/(x + c)^2 </span>
<span>and </span>
<span>(y - y^2)/x = (x/(x + c) - x^2/(x + c)^2)/x </span>
<span>= (x(x + c) - x^2)/(x(x + c)^2) </span>
<span>= (x^2 + cx - x^2)/(x(x + c)^2) </span>
<span>= cx/(x(x + c)^2) </span>
<span>= c/(x + c)^2 </span>
<span>which proves the equality. </span>
Answer:
Due to presence on opposite side of the globe.
Explanation:
My model support the claim that the Northern and Southern Hemispheres have different seasons due to present on different location on the globe. The seasons in the Northern Hemisphere are different and opposite of those in the Southern Hemisphere. Seasons occur because Earth is tilted on its axis. This tilting causes summer in one location whereas winter in other location. The Earth's tilt causes the Southern Hemisphere to lean towards the Sun during summer season of Southern Hemisphere while on the other hand, it is winter season in the Northern Hemisphere which leans away from the Sun.

Explanation:
Waste products may be stored in leaves that fall off.
What are you asking? Slope? If so. You would do change in y over change in x. So subtract 2 and -4 to get positive 6, then subtract 6 and -3 to get positive 9. Your slope is either 1/3 if it’s increasing, or negative 1/3 if it’s decreasing.
The main reason behinds anyone tallness or shortness is the amount of secretion of pituatory hormone. In that case it depends on your body and u cannot do nothing.
