The factored form of this expression is (x+3)(x-3)(x-6)
<h3>Factored form of an expression</h3>
Given the polynomial function
x^3-6x^2-9x+54
Group
(x^3-6x^2)-(9x+54)
Factor out the greatest common factor
x^2(x-6) - 9(x- 6)
Find the factors
(x^2-9)(x-6)
using the difference of two square
(x+3)(x-3)(x-6)
Hence the factored form of this expression is (x+3)(x-3)(x-6)

Answer:
x= -11/4 is a maximum.
Step-by-step explanation:
Remember that a function has its critical points where the derivative equal zero. Therefore we need to compute the derivative of this function and find the points where the derivative is zero. Using the chain rule and the product rule we get that
And then we get that if 
then 
. So it has a critical point at .
Now, if the second derivative evaluated at that point is less than 0 then the point is a maximum and if is greater than zero the point is a minimum.
Since
x= -11/4 is a maximum.
Answer:
-2 1/10
Or -2.1
Step-by-step explanation:
Answer:
8 miles he will walk in 2 hours
Step-by-step explanation:
This is because there are four 15 minute sets in one hour meaning in two hours you will encounter 8 of these sets.
The answer is A, y = (x+3)^2 -3
