Answer:
There are two rational roots for f(x)
Step-by-step explanation:
We are given a function
To find the number of rational roots for f(x).
Let us use remainder theorem that when
f(a) =0, (x-a) is a factor of f(x) or x=a is one solution.
Substitute 1 for x
f(1) = 1-2-5+6=0
Hence x=1 is one solution.
Let us try x=-1
f(-1) = 1-2-5+6 =0
So x =-1 is also a solution and x+1 is a factor
We can write f(x) by trial and error as
We find that factor gives two irrational solutions as
±√3.
Hence number of rational roots are 2.
Answer:
Step-by-step explanation:
By definition, the "Difference" is the result of a subtraction.
It is important to remember that Scientific Notation is in the following form:
Where "a" is a number between 1 and 10 ( but not including 10) and "b" is an Integer.
In this case, according to the information given in the exercise, you know that the Petronas towers are 1,483 feet tall and the Key tower is 947 feet tall.
Then, the diffrence between the heights of those towers can be find by subtracting them. So, this is:
In order to write the difference calculated above in Scientific notation, the Decimal point must be after the first digit; then you must move the Decimal point two places to the left. Therefore, you get that this is:
