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:
WE KNOW THAT THE VOLUME OF THE CUBE IS '
V=a^3
our a=7
V=343 cm^3

Answer:
$77.44
Step-by-step explanation:
If the shoes cost $88 but you get a 20% discount, subtract 20% from 88: -->
$88-20% = $70.4
Then add 8% of 88 to 70.4 -->
8% of $88 = $7.04.
$70.4 + $7.04 = $77.44
Therefore the final price of the shoes are $77.44
