Express 0.0057 in scientific notation

Step-by-step explanation:

0.0057

first number

5

then the rest

7

equal

5.7

There's three zeros behind the number 5 which mean it will be -3

final answer

another example and it will be clear

0.0000403

first number

4

then the rest

03

equal

4.03

There's five zeros behind the number 4 which mean it will be -5

final answer

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.
