Answer:
c=80
Step-by-step explanation:
Based on my reading the critical damping occurs when the discriminant of the quadratic characteristic equation is 0.
So let's see that characteristic equation:
20r^2+cr+80=0
The discriminant can be found by calculating b^2-4aC of ar^2+br+C=0.
a=20
b=c
C=80
c^2-4(20)(80)
We want this to be 0.
c^2-4(20)(80)=0
Simplify:
c^2-6400=0
Add 6400 on both sides:
c^2=6400
Take square root of both sides:
c=80 or c=-80
Based on further reading damping equations in form
ay′′+by′+Cy=0
should have positive coefficients with b also having the possibility of being zero.
Answer with explanation:
Amount that tyler had for buying number of songs from his favorite music website=$ 20
A number line is given which describe the possible quantities of songs that Tyler can buy.
1. No more than 8 songs
4.at most 8 songs
6.a maximum of 8 songs
it would be a, b, and c because if you look at the question and the answers, 3 of the four answers match the 3 of the 4 coordinates
