Answer:

[/tex]1\frac{2}{3}[/tex] inch

Step-by-step explanation:

thickness of wood = 1  1 / 3 inches = 4 / 3 inches

Amount of total drill = 3 inches

Amount of joist drill = amount of total drill - thickness of wood

= 3 - \frac{4}{3}=\frac{9-4}{3}=\frac{5}{3}=1\frac{2}{3}

Thus, the amount of drill in joist is [/tex]1\frac{2}{3}[/tex] inch.

Let y′′′−9y′′+20y′=0. find all values of r such that y=erx satisfies the differential equation. if there is more than one correc
DerKrebs [107]

we are given

differential equation as

y'''-9y''+20y'=0

we are given

y=e^{rx}

Firstly, we will find y' , y'' and y'''

those are first , second and third derivative

First derivative is

y'=re^{rx}

Second derivative is

y''=r*re^{rx}

y''=r^2e^{rx}

Third derivative is

y'''=r^2*re^{rx}

y'''=r^3e^{rx}

now, we can plug these values into differential equation

and we get

r^3 e^{rx}-9r^2 e^{rx}+20re^{rx}=0

now, we can factor out common terms

e^{rx}(r^3 -9r^2 +20r)=0

we can move that term on right side

(r^3 -9r^2 +20r)=0

now, we can factor out

r(r^2 -9r +20)=0

r(r-5)(r-4)=0

now, we can set them equal

r=0

r-5=0

r=5

r-4=0

r=4

so, we will get

r=0,4,5...............Answer
