Find k if (x-3) is a factor of k^(2) x^(2) -kx-2. 

Answers

w(x)=k^2x^2-kx-2\n\n(x-3)\ is\ a\ factor\ w(x)\ then\ w(3)=0.\n\nSubstitute:\n\nk^2\cdot3^2-k\cdot3-2=0\n9k^2-3k-2=0\n9k^2-6k+3k-2=0\n3k(3k-2)+1(3k-2)=0\n(3k-2)(3k+1)=0\iff3k-2=0\ \vee\ 3k+1=0\n3k=2\ \vee\ 3k=-1\n\n\underline{\underline{k=(2)/(3)\ \vee\ k=-(1)/(3)}}
k can be (-1/3) or (2/3).
since (x-3) is a factor. if you put x=3 in the equation, it must be equal to zero. So the equation becomes (9k2 - 3k -2 = 0). if you solve this you will get k=(-1/3) and k=(2/3). You can substitute this k in the original equation and check, (x-3) is a factor.

Is 45 5ths equal to a whole number or a mixed number

Answers

whole number. its 9. If you divide the denominator and numerator bye 5 you will get 9. 
I can't tell what question you are one but 45 5ths is equal to a whole number because 5 goes into 45 9 times

What is the best way to study for a test, quiz or a benchmark assessment, of any subject?

Answers

This may vary between various people but this has helped me.
Some ways to prepare for tests/exams/quizzes is as follows:
1. Get sleep and rest the night before! Because if you ssignment. For me, I like to snack on some things while taking them or drink water but don't dare tired while taking your assignment, your brain doesn't tend to function/think as well.
2.Do something that helps you think while taking the arink to much or else you have to go to the restroom.
3.Look over your notes, research things you don't have a full understanding of.
4.Leading up to the assignment, pay attention to what the teacher is saying!
5.Don't sweat to much over the test. Because I know people who just do it and don't overthink it and do well while if you overthink it, you might make mistakes more often.
6.Do something relaxing, don't tire yourself to much.
7.Be confident.
today i am studying for a history ,and science test plus a music quiz the best way for me is to take all math,music history,English etc  notes,paper's etc and study from them and sometimes the teacher gives u a review paper like today my history teacher gave us a pink review sheet that is due 11/07/14 so she knows we studied hope this helped !!!!!

A 2000 gram sample of radioactivematter will completely decay (be
undetectable) in 20 hours. There
exists a set of ordered pairs (t, m),
where t is the amount of time in hours
that the substance has been decaying,
and m is the mass in grams that has
decayed.
If t > 0, what is the range of m?

Answers

Answer:

The range is 0 < m < 2000 when t > 0

Step-by-step explanation:

* Lets explain how to solve the problem

- The exponential function is f(x)= a(b)^(x) , where

  a is the initial amount and b is the growth factor

- If b > 1, then it is exponential growth function

- If 0 < b < 1, then it is exponential decay function

* Lets solve the problem

- A 2000 gram sample of radioactive  matter will completely decay

 (be  undetectable) in 20 hours

- There is a set of ordered pairs (t , m) exists, where t is the amount

  of time in hours  that the substance has been decaying and m is

  the mass in grams that has  decayed

∵ We can represent this situation by an exponential decay function

∴ m(t)= 2000(b)^(t) , where b is the growth factor which is

  greater than zero and less than 1 , t is the lime in hours and

  m(t) is the mass of the substance in gram

- In any function the domain is the value of x and the range is

 the value of y

∵ In the function the domain is t and the range is m

∵ When t = 0 then m = 2000 ⇒ initial amount

∵ When t = 20 then m will be closed to zero

∴ The domain of the function is 0 < t < 20

∴ The range of the function is 0 < m < 2000

* The range is 0 < m < 2000 when t > 0

How do you compare whole numbers through the millions

Answers

Whole numbers are the numbers 0, 1, 2, 3, 4, 5, 6...and so on. It is easier to compare two numbers through the millions using a place value chart. This is illustrated in the Figure bellow. In that example, we have chosen two numbers:


Number one:8,472,102

Number two:8,470,443


So, by comparing these numbers we will have the following steps:


Step 1. The millions are both 8.

Step 2. The hundred thousands are both 4.

Step 3. The ten thousands are both 7.

Step 4. The one thousands digits are 2 and 0.


Stop in this step and compare the digits, so:


2 is greater than 0 or 2 > 0


Therefore, the solution is:

Number one > Number two, that is:

8,472,102 > 8,470,443


In conclusion, you need to stop in the step at which the digits are not the same and compare them. The greatest number is the one with the greatest digit.
A positive number is greater than a negative number. If both numbers are positive, the longer number - the one with more digits - is larger.
