Answer:

Speed = 90  km per hour.

Step-by-step explanation:

Given  : One of your friends lives 225 km away. It took him 2.5 hours to travel to the cottage.

To find : At what speed did he travel.

Solution : We have given that

Distance covered by friend = 225 km.

Time taken to travel = 2.5 hour.

Speed =  \frac{Distance}{Time}.

Speed =  \frac{225}{2.5}.

Speed = 90  km per hour.

Therefore, Speed = 90  km per hour.

The revenue of Apple® went from $54.5 billion in 2013 to $74.6 billion1 in 2015. Find an exponential function to model the reven
Rus_ich [418]

r = continuous growth rate

revenue t years after 2013 = 54.5×10⁹×e^(rt)

74.6×10⁹ = 54.5×10⁹×e^(2r)

e^(2r) = 74.6/54.5

2r = ln(74.6/54.5)

r = ½ln(74.6/54.5) ≅ 0.15697 = 15.697% per year

Hope this helps!
