2) When an earthquake happens in the Pacific Ocean, the Pacific Tsunami Warning Center uses a formula that measures the possible speed (in \( m / s \) ) of a tsunami. The formula is given by
\( s = ( 9.8 d ) ^ { \frac { 1 } { 2 } }\)
where \( d \) is the depth in meters of the ocean. Suppose, the speed of the tsunami is \( 280 \) meters per second, from what depth did it originate?
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
\( 8,40,200 , \ldots \)
Find the \( 10 \) th term.
(1) q) Put \( S \) above any dash that represents subtraction, \( N \) above any dash that represents negative and \( O \) above any dash that represents opposite. NOTE: You only need to give one answer if more than one answer is possible for a dash.
\( - ( 2 - ( - 3 ) ) - ( - 4 + ( - 2 ) ) + 4 ( - 5 ) + ( - ( - 3 ) )\)
