Adinosaur fossil is 91,910,000 years old. how can you express this age in scientific notation with the highest level of precision?
a. 9x10^7
b. 9.2x10^7
c. 9.191x10^7
d. 9.19x10^7

Step-by-step explanation:

Given: The age of dinosaur fossil = 91,910,000 years

The scientific notation is a way to write a very large or a very small number in the product of a decimal form of number [generally between 1 and 10]and powers of ten.

In the given there are 8 digits, then the given number in scientific notation can be written as

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.
