Can someone help with both of (a) and (b)? If you can give an explanation as-well as an answer would really help. The picture on the right is a clock face. The hour hand is 1 cm shorter
than the minute hand. The tip of the minute hand moves 6.28 cm
when it moves in 15 minutes on the clock face.
8.
(a) What is the length of the minute hand?
(b) How far does the tip of the hour hand move in 1 hour on the
clock face?

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

-4
