Ms.Vogel is riding the stationery bike at the gym. She completes 61 7/8 wheel rotations every 1/2 minute. What is ms. Vogels uni

Drupady [299]

Ms. Vogels unit rate is $123\frac{3}{4}$ rotations per minute.

Step-by-step explanation:

Given,

Rotations completed in 1/2 minute = $61\frac{7}{8}=\frac{495}{8}\ rotations$

$\frac{1}{2}\ minute=\frac{495}{8}\ rotations$

For unit rate, we will multiply both sides with 2

$2*\frac{1}{2}\ minutes=\frac{495}{8}*2\\\\1\ minute = \frac{495}{4}\ rotations\\\\ 1\ minute = 123\frac{3}{4}\ rotations$

Ms. Vogels unit rate is $123\frac{3}{4}$ rotations per minute.

Question 3 Unsaved

bazaltina [42]

Answer:

Step-by-step explanation:

DE given is

y''+8y'+15y=0, y(0)=0, y'(0)=1

Take Laplace on the DE

We get

$s^2 Y(s) -sY(0) -y'(0)+8(sY(s)-y(0))+15Y(s) =0\\s^2 Y(s) -s(0) -1+8(sY(s)-0)+15Y(s) =0\\Y(s)(s^2+8s+15)-1=0\\Y(s) = \frac{1}{s^2+8s+15}$

Simplify to get

Y(s) = $\frac{1}{2}[ {\frac{1}{s+3} -\frac{1}{s+5} }]$

Take inverse

$y(t) = \frac{e^{-3t} -e^{-5t}}{2}$
