from the center of the Earth to the equator is about 3960 mi.
a. What is the measure in radians of the central angle that intercepts tl
arc along the equator between the islands? (5pnts)
equator
b. About how far apart are the two islands? (5pnts)

ryan had a head start of 10 meters.

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)

pi x^2
