Collect like terms
5+5-9i+8i
10-i
You write 1/2 is also equal to .5

It is given that
A stone is thrown into a pond, A circular ripple spreads over the pond in such a way that the radius is increasing at a rate of 2.5 feet per second.
In one second the increment in radius is 2.5 feet
After t seconds, the increment in radius is given by
The area of the circular ripple is
Substitute r(t)=2.5t, we get
The required function is
Hence the fourth option is correct.
If we first turn all of the fractions into decimals, we get:
3/10 = 0.3
1/5 = 0.2
So, ordered from least to greatest we get: 1/5, 0.25, 3/10
