X = 6 cos(t)
y = 3 sin(t)
we can rewrite these equations as:

Taking squares of both equations we get:

Adding both the equations, we get:
Answer: 9/25

F(60) would be the height of the sunflower after 60 days, but idk what the 210 is for. Is there more information for the rest of the question?
Answer:
where 
Step-by-step explanation:
This is an arithmetic sequence with the first term is
= -2.7 and has a common difference of
.
Arithmetic Sequence: 
is the nth term and
is the common difference.
The common difference: -2.7, -8.3, -13.9...
Subtract: -2.7- (-8.3) = -5.6, -13.9 - (-8.3) = -5.6
Common difference:

The total number of patients experienced unwanted side effects is 48
<u><em>Explanation</em></u>
60 patients are given drug A and drug A has unwanted side effects in 40% of the cases.
So, the number of patients experienced side effects for drug A = 40% of 60 
Now 80 patients are given drug B and it has side effects in 30% of the cases.
So, the number of patients experienced side effects for drug B = 30% of 80 
So, the total number of patients experienced unwanted side effects
