Answer:
3 * 10^3 in scientific notation.
3,000 in standard notation.
Step-by-step explanation:
We divide:
3.9 *10^5 / 1.3 * 10^2
= ( 3.9/1.3) * (10^5 / 10^2)
= 3 * 10(5-2)
= 3 * 10^3.
This equals 3 * 1,000 = 3000.
Answer:
3/2

Answer:
D
Step-by-step explanation:
Using the law of sines in ΔABC, then
= 
Substituting in values gives
= 
( cross- multiply )
c × sin38° = 25 × sin31.6° ( divide both sides by sin38° )
c = 
≈ 21.28 → D
