a) A talented athlete has long jump sessions every day. He makes up to 100 long jumps in each training session. The length of each jump, L cantimetres, that the athlete achieves at each consecutive jump is modelled by L(n) = 597 + 2n + log10(n), where n is a jump by number, i.e. n-th jump. i) Find the length of his 15t and 10" jumps. What is the difference D between 1 st and 10th jumps?ii) At what attempt does he reach a 700 cm jump for the first time?h} The current i {in rmt} in an electric circuit is. given by: i: am: - 3-\") where t is time in seeend5. i] Make time t the subject uf'the formula
