On August 20, 1989, in Cologne, West Germany, Said Aouita of Morocco also established a world record when he ran the 3000. m run
zalisa [80]

Answer:

Average speed of Aouita = 6.68 meter per second.

Step-by-step explanation:

To create a world record Aouita ran a distance = 3000 m

He took the time to cover this distance = 7 minutes 29.45 seconds

                                                                 = (7×60) + 29.45 seconds

                                                                 = 449.45 seconds

Since, formula for the average speed is given by,

Average speed = \frac{\text{Total distance covered}}{\text{Total time taken}}

Therefor, average speed of Aouita = \frac{3000}{449.45}

                                                          = 6.675

                                                          ≈ 6.68 meter per second

Average speed of Aouita was 6.68 meter per second.

Write the expression in factored form s^2-20s-100
KatRina [158]

Answer:

The factors of given expression are 10+10√2 and 10-10√2.

Step-by-step explanation:

We have given a quadratic expression.

s²-20s-100

We have to find factors of given expression.

We use quadratic formula to find factors.

x = (-b±√b²-4ac) / 2a

From given expression, a = 1 , b = -20 and c = -100

Putting values in above formula, we have

x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)

x = (20±√400+400 ) / 2

x = (20±√800) /  2

x = (20± √400×2) / 2

x = (20±20√2) / 2

x = 10±10√2

Hence, the factors of given expression are 10+10√2 and 10-10√2.
