5) If a satellite travels 62,000,000 miles from Earth, how can we write it in scientific notation?

6.2*10^7 miles

Step-by-step explanation:

We write scientific notation beginning with a number rounded to 1 decimal place between 0 and 10 then multiply it by a power of 10.

In this case, 62 million can be written as 6.2*10^7

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
