Your class started at 12: 12pm and ended at 12: 50pm. what angle did the minute hand of a watch sweep through during the class? a. 228. b. 132. c. 168. d. 153.

recall that a circle has a total of 360°.

now the clock has 60 minutes, how many degrees are there between each minute? well, that'd be 360°/60, which gives us 6° for every passing minute.

the class started at 12:12, went through to 12:50, that's 38 minutes, and since every passing minute is 6°, that'd be 38 * 6.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

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
