You float 2000 feet along a lazy river water ride. the ride takes less than 10 minutes. give two examples of possible times and speeds.

Step-by-step explanation:

We know that the distance traveled is

The time that took to travel this distance is

This means that the time could be 9 minutes, 8 minutes, 7 minutes. It can be a number between 0 and 10.

The speed is defined as

Replacing all values, we have

Therefore, the speed can be expressed like less than 200 feet per minutes.

Another possible example is using a time of 9 minutes

In this case, the speed would be 222.22 feet per minute or less. Notice that this time the speed is not "less than", we have to include a equality relation, because we already used a time that's inside the interval of time given by the problem.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
