This is just here for the 20 character limit but the answer is in the picture.
Answer:

Step-by-step explanation:
It is a linear homogeneous differential equation with constant coefficients:
y" + 4y = 0
Its characteristic equation:
r^2+4=0
r1=2i
r2=-2i
We use these roots in order to find the general solution:

How many bracelets did you buy just $50 dollars worth and how much did you buy one bracelet for <span />
Answer:0.542=0.500 + 0.040+0.002
= \frac{5}{10} + \frac{4}{100} +\frac{2}{1000}
=5 tenth + 4 hundredths + two thousandths
One tenth = \frac{1}{10}
One Hundredth= \frac{1}{100}
One thousandth= \frac{1}{1000}
