<h2>
The required "option A) 
" is correct.</h2>
Step-by-step explanation:
We have,
..... (1)
To find, 
= ?
Differentiating equation (1) w.r.t. 'x', we get
![\dfrac{dy}{dx}= \dfrac{d[(3x + x^2)^5]}{dx}](https://tex.z-dn.net/?f=%5Cdfrac%7Bdy%7D%7Bdx%7D%3D%20%5Cdfrac%7Bd%5B%283x%20%2B%20x%5E2%29%5E5%5D%7D%7Bdx%7D)
⇒ 
[ ∵ 
⇒

⇒ 
⇒ 
Thus, the required "option A) " is correct.
Use multiplication. To find your answer
Hey!
Since they are 45-45-90 triangles, the two legs are <u>equal</u><u>.</u>
<u />
Therefore x is 
Now, the hypotenuse, y, is the same as any leg times 
So we do * which is 
.
Now we need to simplify that.
is the same as 
which is 
which is

Answer:
12
Step-by-step explanation:
First, replace x and y with 3 and 4. Your equation set-up should be 7(3)-2(4)-1. Now, we can solve
7(3)-2(4)-1=?
21-8-1=?
13-1=?
12=?
Your answer is 12. Hope this helps!
Answer:
Convectional rainfall. - Convectional rainfall occurs when the energy of the sun heats the surface of the Earth, causing water to evaporate to form water vapour. When the land heats up, it warms the air above it. This causes the air to expand and rise. As the air rises, it cools and condenses. ... If this process continues, rainfall will occur.
Orographic or relief rainfall. - Orographic or relief rainfall is caused when masses of air are forced up the side of elevated land formations, such as large mountains, often referred to as an upslope effect. The lift of the air up the side of the mountain results in adiabatic cooling, and ultimately condensation and precipitation.
Cyclonic or frontal rainfall. - Frontal or Cyclonic Rain is caused by cyclonic activity and it occurs along the fronts of the cyclone. It is formed when two masses of air of different temperature, humidity and density meets. For example meeting of moisture laden warm tropical wind with a polar air mass. A layer separating them is called the front.
