Question 1149045
<br>
A decrease of 23% means the value is MULTIPLIED by (100%-23%) = 77% = 0.77.<br>
(a) The 4-year growth factor is 0.77.<br>
(b) The 4-year growth factor is the 1-year growth factor, raised to the 4th power; so the 1-year growth factor is the 4-year growth factor to the 1/4 power.<br<>
{{{0.77^(1/4) = .9367}}} to a few decimal places.<br>
The value t years after 2010 is the initial value, multiplied by the 1-year growth factor t times.<br>
(c) {{{f(t) = 13000(0.09367)^t}}}<br>
