Answer:
nth term is;
0.5n-0.5
Step-by-step explanation:
As we can see, the first term is 0
The common difference is 0.5-0= 1-0.5 = 1.5-1 = 0.5
Formula for nth term of an arithmetic sequence is;
a + (n-1)d
So we have
0 + (n-1) 0.5
= 0.5n-0.5
The Answer is the first one

Answer:
A.
Step-by-step explanation:
Surface area of the original cone
When, radius is quadrupled and slant height is reduced to one sixth
Plug the above values of r and 
in equation (1), new surface area becomes:
<span>B. Decreases.
While evaporation is happening, the temperature is slowing cooling down due to not as much water in the pot that is holding the water. If you have ever taken boiling hot water and dumped half of it out, and immediately put it back on the stove, it doesn't start boiling right away. It takes minutes to heat it back up to that boiling temperature.</span>
