Anumber written in scientific notation has the form a×10k, where 1≤a< 10 and k is an integer, that is, k is one of −3,−2,−1,0,1,2, part a determine the values of a and k when 299,790,000 is written in scientific notation. enter a and k, separated by commas.

scientific notation is given as

here we know that

1 <  a < 10 and

k = whole number

now the number will be

N = 299,790,000

here we know that

so we have

a = 2.99

k = 8

answer: a ball

explanation: because it will bounce

i don't know that i agree with that but what's the question ?
