Alight flashes every two minutes a second light flashes every 3.5 minutes and a third light flashes every four minutes if all three lights flash together at 8 pm what is the next time of the day they were all flash together

Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28

Multiples of 3.5: 3.5, 7, 10.5, 14, 17.5, 21, 24.5, 28

Multiples of 4: 4, 8, 12, 16, 20, 24, 28

The least common multiple of the 3 numbers is 28, so the lights will flash at the same time every 28 minutes.

The time will be 8:28 PM

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
