Solve really stuck much appreciated

Answers:

a)

b) 0.299 s

Step-by-step explanation:

a) We are given the following equation:

If we divide by 2 both the numerator and the denominator, we will have:

b) From this equation:

is the reaction time in seconds

is the distance

is the acceleration due gravity

Solving:

This is the reaction time

g

step-by-step explanation:

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.
