Step-by-step explanation:
n2+5=21
n2 =21-5
n2 = 16
n =16/2=8
ok but what's the question? u gave us info but what's the question
Answer:
- (a) no
- (b) yes
- (c) no
- (d) no
Step-by-step explanation:
"Of the order x^2" means the dominant behavior matches that of x^2 as x gets large. For polynomial functions, the dominant behavior is that of the highest-degree term.
For other functions, the dominant behavior will typically be governed in some other way. Here, the rate of growth of the x·log(x) function is determined by log(x), which has decreasing slope as x increases.
Only answer selection B has a highest-degree term of x^2, so only that one exhibits O(x^2) behavior.
Answer:
b. both functions have a negative slope
Step-by-step explanation:
The given function is
This function is of the form 
, where 
is the slope and 
is the y-intercept.
We can also determine the slope of the function in the table using any two points, say 
.
The slope formula is given by,
.
If 
, then,
.
We can see that both functions have a negative slope.
The correct answer is B.
First we will find out the values of a
a/4=b/7
a=4b/7
Now
(a-b)/b
{4b/7-b}/b
(4b-7b)/7b
-3b/7b
-3/7
