Answer:
The answer is c. f(n)=4n+1
Step-by-step explanation:
In the function of the answers, n is the input and f(n) is the output. So the ordered pairs needs to be at the form (n,f(n))
Additionally, in the ordered pairs given in the question, the first term is the input and the second term is the output. For example in the ordered pair (1,5), 1 is the input and 5 is the output.
So, if we replace n by 1, f(n) needs to be 5. This condition is only satisfied on option c. That's is also prove for every ordered pair as:
For (1,5)
if n=1 then:
f(n)=(4*1)+1=5
For (2,9)
if n=2 then:
f(n)=(4*2)+1=9
For (3,13)
if n=3 then:
f(n)=(4*3)+1=13
For (4,17)
if n=4 then:
f(n)=(4*4)+1=17
Finally, the functions that best represents the rule that the calculator uses to display the outputs is f(n)=4n+1
Amir is incorrect. This is because 0.09 is 1/10 of 0.9 You can see this on a place value chart. Thousands, Hundreds, ones, tenths, and hundredths. Place down the values to see which one is greater. It is the 9 in the tenths place. 135.9. The tenths place is closer to the wholes than the hundredths place.

Answer:
2.)4n>(n/2)^2
3. (The problem isn't clear)
4.)n^2+2n-3=129
5.)n-5=171
Step-by-step explanation:
2.)
4n(four times the number) >(larger than) (n/2)^2 (half the number squared)
4.)
Sum=addition
n^2 (number squared) +2n (twice the number)-3=129
5.)
N(unknown number of pages) -5(amount of pages already read)= 171(the number of pages it took her to finish)
= 3a^2b(cuberoot(b^2)) - 3a^2b^3(square root(3a))
answer is the first choice
