Agolfer’s arm rotates 1/2 of a revolution in 1/10 of a second. if the angular displacement is measured in radians, which statements are true? check all that apply.

the angular velocity is 10π rad/sec.
the angular velocity is 10π rad/min.
the angular velocity is 60π rad/min.
the angular velocity is 600π rad/sec.
the angular velocity is 600π rad/min.

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
