the measure of angle b is 839, and the measure of angle c is 420,
b
what is the measure of angle d in degrees?

Bring the fraction a/a-4 to a denominator of 16-a^2

1yd 1 ft = 1 1/12 1 1/3 1 1/2 1 1/6

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 !
