Answer:

30%

Step-by-step explanation:

Total population=15,000

kantipur=9000

gorkhapatra= 7500

Both magazine=40%

n(k intersection g)=40% of 15,000

=0.4*15,000

=6,000

n(k) =9000

n(g)=7500

n(A union B)= n(k) + n(g) -n(k intersection g)

=9000+7500-6000

=10,500

Population who do no read= Total population - n(A union B)

=15000-10500

=4500

Percentage population who do not read both magazine

=4,500/15,000 * 100

=0.3 * 100

=30%

The differential equation of a certain system is 20⁢y′⁢′+c⁢y′+80⁢y=0
Sholpan [36]

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:

20⁢r^2+c⁢r+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

a⁢y′⁢′+b⁢y′+C⁢y=0

should have positive coefficients with b also having the possibility of being zero.

How do you find percent of a number mentally
olga55 [171]
It isn't easy really but you can always divide the number out. For example 50% of 200 is 100 by dividing 200 by 2 or 25% of 100 is 25 by dividing 100 by 4 since 25% is equivalent to 1/4
