4. find the general solution to 4y"+20y'+25y = 0

Step-by-step explanation:

The given differential equation is 4y"+20y'+25y = 0

The characteristics equation is given by

Now, solve the equation for r

Factor by middle term splitting

Factored out the common term

Use Zero product property

Solve for r

We got the repeated roots.

Hence, the general equation for the differential equation is

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
