Consider the differential equation 2y'' + ty' − 2y = 14, y(0) = y'(0) = 0. In some instances, the Laplace transform can be used

to solve linear differential equations with variable monomial coefficients. Use Theorem 7.4.1., Theorem 7.4.1 Derivatives of Transforms If F(s) = ℒ{f(t)} and n = 1, 2, 3, . . . , then ℒ{tnf(t)} = (−1)n dn dsn F(s), to reduce the given differential equation to a linear first-order DE in the transformed function Y(s) = ℒ{y(t)}. Solve the first-order DE for Y(s). Then find y(t) = &1{Y(s)}.

Kira drove 522 miles in 9 hours.<br> At the same rate, how many miles would she drive in 7 hours?
Ipatiy [6.2K]

GIven:522 miles in 9 hours.

So if we divide 522 by 9 we get that Kira drives 58 miles per hour.

Now in 7 hours Kira just drives 7 times that which means Kira drives.

58*7=406 miles

Hope this helped!

The mountain trail at Tanner Park is 8 miles long traveling to the top of the mountain and back. Grayson is making his way back
AnnZ [28]

Answer:

Speed of hike = 1.7 miles per hour

Step-by-step explanation:

Given:

Total distance = 8 miles

Distance already traveled = 4.6 miles

Total time remain to travel  = 2 hour

Find:

Speed of hike

Computation:

Distance remain = Total distance - Distance already traveled

Distance remain = 8 miles - 4.6 miles

Distance remain = 3.4 miles

Speed of hike = Distance remain / Total time remain to travel

Speed of hike = 3.4 / 2

Speed of hike = 1.7 miles per hour

Please help me question is in the picture
tekilochka [14]

Answer:

172.70 sq. ft.

Step-by-step explanation:

The surface area of a circular cone is

SA = \pi r^{2} + \pi rl       r = radius of base         l = slant height

r = 4.4    and     l = 8.1

SA = 3.14 (4.4^{2}) + 3.14(4.4)(8.1)\\

SA = 3.14(19.36) + 111.9096

     = 60.7904 + 111.9096

     = 172.70 sq. ft.
