4x(5x3)=(4x5)x3 the associative property basically just moves the parentheses.
Answer:
12 dollars
Step-by-step explanation:
<h3>Lona should have 12 dollars because it says that it is <em>2 1/3</em> as much as Mary-Anns amount. You would divide 28➗2 1/3=12</h3><h3 /><h3>hope this helps</h3>
Using the Laplace transform, the value o y' − 2y = (t − 4), y(0) = 0 is⇒y(t) = 0 e^-t + u(t -1)e^1-t
Laplace rework is an critical rework approach that is in particular useful in fixing linear normal equations. It unearths very huge applications in regions of physics, electrical engineering, control optics, arithmetic and sign processing.
y' − 2y = (t − 4),
y(0) = 0
Taking the Laplace transformation of the differential equation
⇒sY(s) - y (0) + Y(s) = e-s
⇒(s + 1)Y(s) = (0+ e^-s)/s + 1
⇒y(t) = L^-1{0/s+1} + {e ^-s/s + 1}
⇒y(t) = 0 e^-t + u(t -1)e^1-t
