If the general solution of a differential equation is y(t)equals=Upper C e Superscript negative 4 t Baseline plus 7Ce−4t+7, wh

Maru [420]

Answer:

$y(t) = 3e^{-4t}+7$

Step-by-step explanation:

$y(t) = Ce^{-4t}+7$

At <em>y</em>(0) = 10, when <em>t</em> = 0, <em>y</em> = 10.

$y(0) = 10 = Ce^{-4\times0}+7$

$10 = C+7$

$C = 3$

Hence, the solution is

$y(t) = 3e^{-4t}+7$
