Nolan rides his bike 63 miles in 270 minutes. what is his average speed in miles per hour?

14 mph because 270 / 60 (60 minutes in an hour) = 4.5 and 63 / 4.5 = 14 so 14mph

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.
