A line segment whose endpoints are \( ( 3,9 ) \) and \( ( 7 , k ) \) is perpendicular to a line whose slope is \( - 2 \) . Which of the following is the value of \( k \) ?
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.
\( - ( 2 - ( - 3 ) ) - ( - 4 + ( - 2 ) ) + 4 ( - 5 ) + ( - ( - 3 ) )\)
