The graph shows the altitude of a bird over time. a graph measuring altitude and time.
what is the slope of the line and what does it mean in this situation?
the slope is –500 . this means that the bird descends 500 m each minute.
the slope is –350 . this means that the bird descends 350 m each minute.
the slope is 350. this means that the bird ascends 350 m each minute.
the slope is 500. this means that the bird ascends 500 m each minute

The slope is –500 . This means that the bird descends 500 m each minute

Step-by-step explanation:

The slope of a line that passes through (a,b) and (c,d) is given by :-

From the graph , the x-axis is representing time in minutes and y-axis is representing altitude in meters .

The line is passing through (2,5000) and (5,3500).

Then, the slope of the line will be :

I.e. slope =- 500.

Since , the slop is negative it means the bird descends 500 m each minute.

Hence, the correct answer is

The slope is –500 . This means that the bird descends 500 m each minute

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

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
