The order of magnitude is calculated by use of log function. log(240000) = 5.38 so the order is 5 (from what I've see we round down even if it was 5.999 but this may be wrong in some cases).
There's an error in your version of the function. Compare yours to the original post.
Consider what happens to this function as x becomes increasingly large:
the denominator grows quickly and without bound. The numerator stays the same. In such a situation, the function goes to zero as x increases. Thus, y = 0 is the horiz. asympt. The denom. is never zero, so there are no vert. asymp.
Answer:
9x^2-25
Step-by-step explanation:
You can solve this problem by using FOIL:
- FOIL (First, Outer, Inner, Last)
First: 3x*3x= 9x^2
Outer: 3x*-5= -15x
Inner: 3x*5 = 15x
Last: 5*-5= -25
Now add what we got together:
9x^2 -15x +15x -25
Answer: 9x^2 - 25
Note: Whenever when we see conjugates(coefficients of variables are same but real numbers are opposites) like these we can ignore the outer and inner of the foil process as they cancel out.
Hope this helps!
Answer:
<h2>67hours hours</h2>
Step-by-step explanation:
Given
she works $30 for 1 hour
in 40 hours she will earn 40*30= $1200
this means that a week she earns $1200
let the number of weeks she needs to work be x
40x*(30)<=2000
1200x<=2000
x<=2000/1200
x<=1.66
the number of hours in a week is 40
40*1.66=66.66
67hours
hence she must work for at least 67hours
