Consider this sequence: 3, -3/2, -6,-21/2, ... What is the explicit function that defines this sequence? If arithmetic, write the function in simplified form. If geometric, write the function with an exponent of n-1. Be sure to keep all numbers in improper fraction form.​

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

dont trust me im no expert these losers made me fail a test bro this sucks

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
