Given the trinomial, what is the value of the coefficient 'b' in the factored form? 2x2 + 14xy − 36y2 = 2(x + by)(x − 2y) b= numerical answers expected! answer for blank 1:

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)

what are the answer choices given for this problem?
