Hile testing a new vaccine, a lab technician noticed that the number of bacteria reduced by half every minute. how long does it take for 3,000 bacteria to reduce to 375?

see explanation

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

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
