Answer:
Step-by-step explanation:
<em>Speed = distance/time</em>
- Distance = 20.4 miles
- Time = 17 minutes = 17*1/60 hours = 17/60 hours
<u>Speed is:</u>
- 20.4 : 17/60 =
- 20.4*60/17 =
- 72 mph
<u>Alyn exceeded the limit by:</u>
Answer:
y = 5 e^r * t
Let y be the population in billions and t the value of elapsed years
7 = 5 e^r * t is the equation being used where t = 15
7/5 = e^r * t
ln 7/5 = r * t taking ln of both sides
r = .336 / 15 = .0224
y = 5 e^(.0224 t) is then our equation
Check - suppose you want y at 2020
y = 5 e^(.0224 * 20) would be the equation
y = 5 e^.449 = 7.83 billion - seems to be a reasonable answer
