5. Tyler's cell phone plan costs $350 to start, then there is a $50 charge each month. On the same grid as Han's plan, graph the cost of Tyler's cell phone plan over a period of two years. Describe how the two graphs are the same and how they are different.

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)

2x^2+5x+17

your welcome. : )
