Answer:
4 friends will get watermelon
Step-by-step explanation:
1. 1 1/2 + 1 1/2 = 3
2. 1 1/2 + 1 1/2= 3
3. 3+3=6
4. Now count how many times we added 1 1/2.
5. If you counted correctly, you should've gotten 4.
Answer:

Step-by-step explanation:
A recursive rule allows us to find the term in a sequence from the previous term.
From the given geometric sequence find r the common ratio
r = 
= 
= - 4
Hence recursive rule is
= - 4
( a₁ = 
)
Answer:
√2
Step-by-step explanation:
tan(x) = -1
x = arctan(-1)
x = -π/4
Now since x is between 3π/2 and 2π use use the general form
nπ-π/4
taking n = 2
2×π-π/4
= 7π/4
now tan (7π/4) = -1
so sec (7π/4) = √2
