A 41 gram sample of a substance that's used to detect explosives has a k-value of 0.1392 N = Noel -kt No = initial mass (at time t = 0) N = mass at timet k = a positive constant that depends on the substance itself and on the units used to measure time 6 = time, in days​

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

translate k to n and reflect across the line containing jk.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
