Bela started studying how the number of branches on her tree grows over time. Every 2.92.92, point, 9 years, the number of branches increases by an additional 83\%83%83, percent, and can be modeled by a function, NNN, which depends on the amount of time, ttt (in years). When Bela began the study, her tree had 606060 branches. Write a function that models the number of branches ttt years since Bela began studying her tree.

Step-by-step explanation:

If an initial number of branches increases at a rate r% for a duration of t years in k periods, the Number of branches (N(t) at any time t will be modeled by the equation:

Initially Bela's tree had 60 branches, therefore, =60.

Rate of Increase, r=83%=0.83

Period, k=2.9 Years

Therefore, the number of branches (after t years)

The function that models the number of branches t years since Bela began studying her tree is  

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
