A Suppose 13-year and 17-year cicadas both appear this year. When will both
meriva

Answer:Stragglers can emerge 1 or 4 years early or 1 or 4 years late. Don't be surprised if you see some periodical cicadas emerge earlier than planned this year. 17-year brood members are most likely to straggle 4 years early, and 13-year brood members are most likely to straggle 4 years late.

Y"-4y'+4y=0 y1=e^2x find the general solution
Karo-lina-s [1.5K]
Given that y_1=e^{2x} is a known solution to the ODE, we can reduce the order of the ODE to find a second solution of the form

y_2=y_1v=e^{2x}v
\implies {y_2}'=2e^{2x}v+e^{2x}v'
\implies {y_2}''=4e^{2x}v+4e^{2x}v'+e^{2x}v''

Substituting into the ODE, we get

(e^{2x}v''+4e^{2x}v'+4e^{2x}v)-4(e^{2x}v'+2e^{2x}v)+4e^{2x}v=e^{2x}
e^{2x}v''=e^{2x}
v''=1
\implies v'=C_1
\implies v=C_1x+C_2
\implies y_2=C_1xe^{2x}+C_2e^{2x}

We already know about e^{2x} as a solution to the ODE, which means y_2=xe^{2x}.

That covers the characteristic solution. To find the particular solution to the nonhomogeneous ODE, suppose there is a solution of the form

y_p=ax^2e^{2x}
{y_p}'=2ax(x+1)e^{2x}
{y_p}''=2a(2x^2+4x+1)e^{2x}

Substituting into the ODE yields

{y_p}''-4{y_p}'+4{y_p}=2ae^{2x}=e^{2x}\implies a=\dfrac12

so that the general solution is

y=C_1y_1+C_2y_2+y_p
y=C_1e^{2x}+C_2xe^{2x}+\dfrac12x^2e^{2x}

Maekyala's Room is 65m by 3m by 3m.How many cubic meter of air will her room hold?
UNO [17]

Answer:

<u>585 Cubic Meters</u>

Step-by-step explanation:

Since the room is in the shape of a rectangular prism, to find the volume, you'll do Volume = Length * Width * Height

So, 65 * 3 * 3 = 585 Cubic Meters

<em>(its in cubic meters because it is measuring a volume of space)</em>

How are the graphs of the functions f(x) = . 16and g(x) = 3/64 related?
Natalija [7]

Answer: A  there are equivalent.

Step-by-step explanation:

f(x) = \sqrt{16}^x  reduces to  f(x)=4^{x}  

g(x)= \sqrt[3]{64}^{x}   also reduces to g(x) = 4^{x}

Solve the following inequality for mm. Write your answer in the simplest form.<br> 10m − 3 &gt; 6m+1
Georgia [21]

Answer:

m > 1

Step-by-step explanation:

Given: 10m − 3 > 6m+1

Add 3 to both sides: 10m > 6m + 4

Subtract 6m from both sides: 4m > + 4

Divide both sides by 4: m > 1
