To find the number of miles in 100 kilometers,

a. multiply 100 by 0.6215
b. divide 100 by 0.6215
c. multiply 100 by 3.281
d. divide 100 by 3.281

A

Step-by-step explanation:

100 miles becomes smaller when multiplied by decimals and 1 mile is about 2 km a 5 k is about 3 miles

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.
