Question

The distance it takes a car to come to a complete stop after the brakes are applied is related to the speed that the car is traveling. the stopping distances and speeds are shown in the table.

Which equation represents the data in the table?

A) s=4√d
B) s=0.37d+20 NOT B
C) s=13.7log20
D) s= 1/25d²

Please choose one of the answers provided.

Edit: It is not Choice B

Answer 1

Answer: A) s=4√d

Step-by-step explanation: No explanation (sorry) I just took the quiz.

Answer 2

Hence, Option 1 is correct equation
`s=4√(d)`

Explanation:

The distance it takes a car to come to a complete stop after the brakes are applied is related to the speed that the car is traveling. the stopping distances and speeds are shown in the table.

d s

20 17.89

40 25.30

60 30.98

80 35.78

100 40.00

We will check each option for table.

`s=4√(d)`

For d=20, Put d=20 into
`s=4√(d)`

`s=4√(20)\approx 17.89`

For d=40, Put d=40 into
`s=4√(d)`

`s=4√(40)\approx 25.30`

For d=60, Put d=60 into
`s=4√(d)`

`s=4√(60)\approx 30.98`

For d=80, Put d=80 into
`s=4√(d)`

`s=4√(80)\approx 35.78`

For d=100, Put d=100 into
`s=4√(d)`

`s=4√(100)\approx 40.00`

All the value of table satisfy the first equation.

Hence, Option 1 is correct equation
`s=4√(d)`
