For the following conditional, identify the converse and the truth value of the converse: if an angle is a right angle, then its measure is 90°. a) if an angle is not a right angle, then its measure is 90°. false b) if an angle has measure 90°, then it is a right angle. true c) if an angle has measure 90°, then it is a right angle. false d)if an angle is not a right angle, then its measure is not 90°. true

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 !
