hi
I Don't know
sorry
I will try to say next time
Answer: W=-1.8
Step-by-step explanation:
Divide both sides by 2.02 and you are left with W=-1.8.
Hope this helps!
If y = cos(kt), then its first two derivatives are
y' = -k sin(kt)
y'' = -k² cos(kt)
Substituting y and y'' into 49y'' = -16y gives
-49k² cos(kt) = -15 cos(kt)
⇒ 49k² = 15
⇒ k² = 15/49
⇒ k = ±√15/7
Note that both values of k give the same solution y = cos(√15/7 t) since cosine is even.
The students that are correct are Jake , and Liu because 51, and 21 are composite.
Hope this helps!
