T=-16... I hope this helps love! :)
Answer:
= 4 
Step-by-step explanation:
There is a common ratio r between consecutive terms , that is
r = - 20 ÷ 4 = 100 ÷ - 20 = - 5
This indicates the sequence is geometric with nth term ( explicit formula )
= a₁ 
where a₁ is the first term and r the common ratio
Here a₁ = 4 and r = - 5 , then
= 4 
Answer:
c because if you subtract
For this case we have the following equation:
s = 300 / d
Where,
s: the speed of the current in a certain whirlpool
d: the distance from the center of the whirlpool
We have then that:
If the distance from the center of the whirpool is large, the speed is small.
If the distance from the center of the whirlpool is very small, the speed tends to infinity
Answer:
Large distance, small speed.
Short distance, speed tends to infinity.
