The inequality equation represented by the parabola graph is;

y < (x - 2)(x - 8)

<h3>How to Interpret a Quadratic Graph?</h3>

We are told that the zeros of a parabola are 2 and 8. This means that the roots of the quadratic equation represented by the graph are 2 and 8. Thus, the factors of this quadratic graph can be written as;

(x - 2) and (x - 8)

Now, one rule about graphing inequalities is that If the inequality symbol is ≤ or ≥ , then the region includes the parabola, so it should be graphed with a solid line.

Otherwise, if the inequality symbol is < or > , the parabola should be drawn with a dotted line to indicate that the region does not include its boundary.

Now, since the parabola is drawn with a dashed line, it means that the inequality sign will be  < or > .

Lastly, since the outside of the parabola is shaded, it means that the inequality will be less than. Thus, our inequality equation is;

y < (x - 2)(x - 8)

One estimate of the population of the world on January 1, 2005, is 6,486,915,022. The population is estimated to be increasing a
luda_lava [24]
The answer is <span>8,686,308,783.</span>

To calculate this, we will use the equation for exponential function:
y=x(r+1) ^{n}
y - the future population
x - the current population
r - the rate of increasing the population
n - the number of years

It is given:
x = 6,486,915,022
r = 1.4% = 0.014
n = 2026 - 2005 = 21

Therefore:
y= x(r+1)^{n} =6,486,915,022*(0.014+1) ^{21} = 8,686,308,783

A train is moving at an average speed of 180 m/s. how long will it take to reach the station. Both stations are 80 km apart?
Alexxandr [17]

1 km = 1000 meters.

Find total meters: 80 km x 1000 meters per km = 80,000 meters.

Divide total meters by the given speed:

80,000 meters / 180 m/s = 444.44 seconds.

1 minute = 60 seconds

444.44. Seconds / 60 seconds per minute = 7.41 minutes = 7 minutes 24.42 seconds

Total time = 7 minutes 24.42 seconds

Round as needed.
