According to a weather service, the formula to calculate the average temperature in New Orleans for any given day of the year is T(x) = 20 + 8cos[ 2π 365 (x - 197)]. What is the average temperature in New Orleans on day 245 of the year? (to the nearest tenth °C) A) 18.7 °C B) 21.3 °C C) 25.4 °C D) 37.2 °C

answer: idk

step-by-step explanation:

x =-.20752

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
