Answer:

The vertex of a parabola is found by

'h' position = -b / (2 * a) = 0 / 2 * -4 = 0

'y' position = ah^2 + bh + c = -4*0 + 0 -20

vertex = (0, -20)

Answer:

See below

Step-by-step explanation:

$x = \frac{1}{2} \times \sqrt{6} \\ \\ x = \frac{ \sqrt{6} }{2} \\ \\ y = \frac{ \sqrt{3} }{2} \times \sqrt{6} \\ \\ y = \frac{ \sqrt{3 \times 6} }{2} \\ \\ y = \frac{ \sqrt{18} }{2} \\ \\ y = \frac{ 3\sqrt{2} }{2}$

While traveling to the office, dolly drives her car at a speed of 60 kmph and then suddenly the car stopped on half of her dista

lisabon 2012 [21]

The average speed of Dolly is 33.33kmph.

Average Speed:

The average speed is defined as the total distance travelled by the object in a particular interval of time. It can be calculated by dividing the total distance travelled by the total time taken.

So, Average Speed = total distance / total time

Here,

Let the total distance is 100 km.

Therefore, consider she will travel 60 km at speed of 60 kmph , 30 km at speed of 30 kmph and 10 km at speed of 10 kmph.

she will required times of 1 hour, 1hour and 1hour

So,

Average speed = 100 / (1 + 1 + 1)

=> 100 / 3 = 33.33
