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.
Well to find this answer, you want to divide $1.39 by 67.6. When you do this you get 0.0205. This is roughly 2 cents per ounce.
Answer:
95
Step-by-step explanation:
Formula -
Triangle Area - 1/2bh
Square - l x w
Triangle - 5 x 7 = 35/2 = 17.5
Since there are four triangle, we will multiply 17.5 x 4 which is equal to 70
Square - 5 x 5 = 25
Now we add both 70 and 25 which is 95
So the total surface area is 95
