How many fire extinguishers must be carried onboard motorized boats, with installed fuel tanks, that are between 26 and 40 feet in length?

The number of fire-extinguisher that are required to be carried onboard motorized boats depends on the size of the boat. The main purpose of fire extinguishers is for the protection of the motor engine. Thus, For a 26 and 40 feet in length, at-least two B-I extinguishers or one B-II are required to carry.

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
