Sqrt 80n^2 = sqrt 40x2xnxn = sqrt 20x2x2xnxn = sqrt 10x2x2x2xnxn = sqrt 5x2x2x2x2xnxn
Pull out numbers and letters in groups of 2
2x sqrt 5x2x2xnxn
2x2x sqrt 5xnxn
2x2xnx sqrt 5
Multiply the numbers and letters on the outside of the radical
4n x sqrt 5 is the final answer.
Keith's bank account starts with $250 and he adds $150 to it every month. If <em>m</em> is the number of months that have passed, then the amount of money (in dollars) in his account is given by
250 + 150<em>m</em>
<em />
Victoria's account starts with $2000 and she removes half of it each month. So after <em>m</em> months, her account has a value of
2000/2^<em>m</em>
<em />
If you were to plot these amounts, then
(a) Keith's account's value is indeed linear - TRUE
(b) Keith is constantly adding money to his account, so its value is increasing - FALSE
(c) Victoria's account's value involves an exponential expression - TRUE
(d) Victoria is removing money, so the value is decreasing - TRUE
Your answers are correct except for (c).
I'm going to take a guess regarding what you meant to type in:
<span>3x-9 X +6x+5
E(x)= ------- × -------------
2 2
X -9 X +5x+6
3(x+3) 6x+5
becomes E(x) = ----------- * ------------
x-9 5x+6
This cannot be reduced.
Try again to share this problem. Thank you.
