The common ratio between terms is 3, so the sequence has general
-th term

for
. The term exceeds 7000 when

which means the first time
exceeds 7000 occurs when
. Indeed,

while the previous term would have been

Answer:
±sqrt(T*L/m)=v
Step-by-step explanation:
T=mv^2/L
We want to solve the equation for v
Multiply each side by L
T*L=mv^2/L
*L
T*L=mv^2
Divide each side by m
TL/m=mv^2/m
T*L/m=v^2
Take the square root of each side
±sqrt(T*L/m)=sqrt(v^2)
±sqrt(T*L/m)=v
Answer:

Step-by-step explanation:
