Hence, he traveled 270.9 miles.
Answer:
B. C. and E.
Step-by-step explanation:
C = sqrt(e/m)
You can get this by first dividing away the m and then taking the square root of both sides.
lox (x) = -5
rewrite the equation in exponential form:
10^-5 = x
10^-5 = 1/10000
1/10000 = 0.00001
That is the correct answer.
