Answer:
6.3 * 10^5
Step-by-step explanation:
(7 * 10^6) * ( 9 * 10^-2)
= 63 * 10^(6-2)
= 63 * 10^4
= 6.3 * 10^5 (Scientific Form).
Answer: 22 1/2
Step-by-step explanation: first convert 4 1/2 into a mixed # = 9/2
The divide that by 5 (mult by reciprocal)
Reciprocal is the # flipped so,
9/2 x 1/5
= 45/2
divide 45 by 2
(fog)(2)=f(g(2))
so first evaluate g(2)
we know that g(2)=7
then now we evaluate f(7)
answer is 12
see
f(g(2))=f(7)=12
