\displaystyle \frac{4x^3-12x^2+8x}{-4x}=\frac{4x^3}{-4x}+\frac{-12x^2}{-4x}+\frac{8x}{-4x}\\\\=-x^2+3x-2

This result corresponds to the first selection.

A car travels at a constant speed. What is the car's speed between checkpoints, expressed as a unit rate? Checkpoint A 1:00 PM T
storchak [24]
Average speed  

Average speed between the checkpoints  
distance between the checkpoints
divided by
time between the checkpoints. 

Distance between the checkpoints = 
(mileage at B) minus (mileage at A)
=(208)-(120)  =  88 miles .

Time between the checkpoints = 
time at - time at A

=(3:00 PM) - (1:00 PM) =  2 hours .

Average speed between the checkpoints  =  

(88 miles) / (2 hours)

=44 miles per hour .

Suppose a scientist reported the following data regarding the presence bacteria during the first four hours of testing for a new
OlgaM077 [116]

The recursive geometric sequence that models this situation is:

f(n) = 0.9f(n-1)

f(1) = 90000

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

It can be represented by a recursive sequence as follows:

f(n) = qf(n-1)

With f(1) as the first term.

In this problem, the sequence is: 90.000: 81,000; 72,900; 65,610, hence:

q = \frac{65610}{72900} = \cdots = \frac{81000}{90000} = 0.9

f(1) = 90000

Hence:

f(n) = 0.9f(n-1)

f(1) = 90000
