The outside temperature was 73°f at 1.p. m and decreases at a rate of 1.5°f each hour. what expression can be used to determine the temperature h(h is the variable) hours after 1.p. m?

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

i think 1: 2
