A school vending machine sells cartons of milk and juice. On a typical day: No cartons are sold between 7 A. M. and 8 A. M., or from 5 P. M. onward The machine has a capacity of 100 cartons. At 7 A. M. it is three-quarters full. From 8 A. M. to 10 A. M., 10:15 A. M. to noon, and from 1 P. M. to 3 P. M. the students are in class. Students are NOT allowed to use the vending machines during class time. The machine is filled at 11 A. M. and at 4 P. M. Sketch a graph of the number of cartons in the vending machine as a function of time.

step-by-step explanation:

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

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
