Find all solutions to 12tan(2pi/5x)= 12(sqrt 3) in the interval 0< x < 10

a

Step-by-step explanation:

12tan(2pi/5x)= 12(sqrt 3)

tan(2pi/5x)= sqrt 3

2pi/5x = pi/3, 4pi/3, 7pi/3, 10pi/3

x = 5/6, 20/6, 35/6, 50/6

x = 5/6, 10/3, 35/6, 25/3

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
