Write the given second order equation as its equivalent system of first order equations. u″+5u′+4u=0 u″+5u′+4u=0 use vv to repre

sent the "velocity function", i.e. v=u′(t)v=u′(t). use vv and uu for the two functions, rather than u(t)u(t) and v(t)v(t).

v = u', so v' = u'' and the original equation can be written

... v' + 5v + 4u = 0

Then the system of first-order equations is

... u' = v

... v' = -5v -4u

finlep [7]
It's definitely a low data overlap. It's not medium because there's not a solid amount of matching data, and its not 'none' because there is matching data.
so it’s C.

Please help find the value of t?
Gwar [14]

Step-by-step explanation:

volume=8448m²

volume=l×b×h

=11m×8m×t

=88m²×t

therefore, 88m²×t=8448m²

t= 8448/88

= 96

Check:-

volume= l×b×h

=11m×8m×96

=8448m³

Our answer is correct

Y-6=4(x+5) what are the Y and X intercept
Misha Larkins [42]
Hello.

<span>Reorder the terms: -6 + y = 4(x + 5)

  Reorder the terms: -6 + y = 4(5 + x) -6 + y = (5 * 4 + x * 4) -6 + y = (20 + 4x)

  Solving -6 + y = 20 + 4x Solving for variable 'y'.

 Move all terms containing y to the left, all other terms to the right.

 Add '6' to each side of the equation. -6 + 6 + y = 20 + 6 + 4x

 Combine like terms: -6 + 6 = 0 0 + y = 20 + 6 + 4x y = 20 + 6 + 4x

 Combine like terms: 20 + 6 = 26 y = 26 + 4x

 Simplifying y = 26 + 4x


</span>x-intercept: <span><span>(−<span>132</span>,0)</span><span>(-<span>132</span>,0)</span></span>y-intercept: <span>(0,26<span>)

Have a nice day</span></span>
