$10^{-x}=7^{4x}\\
\ln 10^{-x}=\ln 7^{4x}\\
-x \ln 10=4x\ln 7\\
-x \ln 10-4x\ln 7=0\\
x(-\ln 10-4\ln 7)=0\\
x=0$

Find the general solution of the given higher-order differential equation. y''' − 9y'' 15y' 25y = 0

laiz [17]

The general solution of the given higher-order differential equation. y''' − 9y'' 15y' 25y = 0 is Y= c1e^-x +c2e^5x + c3xe^5x

m^3 -9m^2+15m+25=0

Possible rational roots = 1,-1,5,-5,25

Now on putting these possible rational roots which have been found by the discriminant and hit and trial method,

we will check these roots.

m=-1 comes out to be a root of the equation.

m^2-10m+25=0

(m-5)(m+5)=0

(m-5)^2=0

m=5

So the general equation comes out to be

Y= c1e^-x +c2e^5x + c3xe^5x

WARRIOR [948]

Answer:

V = 12,348·π

Step-by-step explanation:

The given parameters of the glass Vase are;

The shape of the glass vase = A sphere

The radius of the vase, r = 21 inches

The given formula for finding the volume of a sphere is $V = \dfrac{4}{3} \cdot \pi \cdot r^3$

Therefore, when r = 21 inches, we get;

$V = \dfrac{4}{3} \cdot \pi \cdot 21^3 = {12,348 \cdot \pi}$

Therefore, the expression for finding the equation of the spherical glass vase, V = 12,348·π
