The general solution of a differential equation of the form ay'' + by' + cy is given by Ae^mx + Be^nx; where m and n are the root of the quadratic equation ax^2 + bx + c
The general solution of <span>y'' + 4y' is given by </span><span>Ae^mx + Be^nx; where m and n are the root of the quadratic equation x^2 + 4x = 0
x(x + 4) = 0
x = 0 or x = -4
Therefore, the general solution is Ae^(-4x) + Be^0x = Ae^(</span>-4x) + B

Step-by-step explanation:
The meaning of circumference is to find the distance around a circle or in other words perimeter by using the formula C=2πr or C=<span>πd.
On this case it is asked you to find the circumference of a circle with a diameter of 3 meters, so you will use the formula C=2</span><span>πr.
C=2</span><span>πr
C=2(3.14)(3)
C=18.84 meters
The circumference of the given circle is 18.84 meters.</span>
Answer: A) 3
Reasoning: 30% of a number is 90, to find this divide 90 by .30
90/.30=300
So 30% of 300 is 90
Now 1% of 300
300 x .01=3
So the answer is 3
