For what values of k
sergey [27]

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.

A balloon has a circumference of 28 in. Use the circumference to approximate the surface area of the balloon to the nearest squa
Soloha48 [4]
C=2πr

r=C/(2π), now the surface area is:

A=4πr^2, using r found above we have:

A=4πC^2/(4π^2)

A=C^2/π, we are given that C=28 so:

A=28^2/π in^2

A=784/π in^2

A≈250 in^2 (to nearest square inch)
