Exponential 1 point
Which exponential function, after being reflected over the x-axis, has a y-
intercept at (0, -4) and the right side of the graph approaches y = 0? *
Oy=4(2)^x
Oy=4(1/2)^x
y=-4(2)^x
y=-4(1/2)^x

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

i dont have an answer

step-by-step explanation:

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
