One hour after taking off, an airplane was 210 km from the airport. After three hours, the airplane was 760 km from the same airport. Assuming the airplane
maintained the same speed throughout the flight, how fast was it flying?

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
