Using V = lwh , find an expression in factored form for the volume of this prism. Explain the general steps you used to arrive a
Lorico [155]
I did this before the correct answer is.

Using the given equation of,
                              V = lwh
The volume of the given prism in the figure is,
                              V = (x² - x / 4x + 1) (2x - 5)(24x² + 6x / x - 1)
By factoring,
                            V = ((x)(x - 1) / (4x + 1))(2x - 5)((6x)(4x + 1) / (x - 1))
Eliminating terms appearing in both the denominator and numerator,
                           V = (x)(2x -5)(6x)

two data sets have the same mean. can you assume that the ranges of the two data sets are about the same? give an example to jus
nirvana33 [79]

No, you can't. Here's two different data sets with a mean of 123:

{3, 33, 333}

{122, 123, 124}

The range of the first set is 330, and the range of the second set is 2. These are very different ranges, so you can't assume that the ranges of the two data sets are about the same.

A car is traveling at a constant speed of 45 miles per hour. How many feet does it travel in 3 seconds? Remember that 1 mile is 
Dafna1 [17]

First you can convert 45 miles per hour to feet per hour:

45 × 5,280 = 237,600 feet per hour

Now you must remember that there are 60 minutes in an hour, and 60 seconds in a minute. So you can divide 237,600 feet per hour by 60 to get feet per minute:

237,600 ÷ 60 = 3,960 feet per minute

Now you just have to divide 3,960 by 60 again to get feet per second:

3,960 ÷ 60 = 66 feet per second

Now you know how fast the car can travel (in feet) in a second. So to work out how many feet it travels in 3 seconds, you just have to multiply 66 by 3:

66 × 3 = 198 feet

Therefore your final answer is <em>198 feet</em> :)
