Let y = safe load in pounds and x = depth in inches for a certain type of rectangular horizontal beam. A constant of
proportionality exists such that y = kx2.
Determine the constant k for a beam with y = 1,000 pounds and x = 5 inches.
What is a safe load if the depth of the beam is 10 inches?
800 pounds
4,000 pounds
10,000 pounds

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 !
