Describe the graph of the function. y = 4x2 + 16x – 18

The graph is a parabola with axis of symmetry at x = –2.

The graph is a parabola with axis of symmetry at x = 2.

The graph is a parabola with axis of symmetry at x = 18.

The graph is a parabola with axis of symmetry at x = 4.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
