A boulder is lifted by a forklift a distance of 10.5 meters with a force of 30 Newtons. An excavator is able to produce 4.5 times the amount of work of the forklift when it lifts a car 2.5 meters out of a parking space. A crane is able to exert 12 times the force of the excavator on a steel beam being lifted onto a building. How much work is done on the beam if it is lifted 23 meters high? HELP PLS SHOW WORK

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 !
