Answer:
Abc is the whole explanation.
Answer: 4w + 28
Step-by-step explanation:
4 gets multiples by everything in the parentheses. So 4 times w = 4w. And 4 times 7 is 28. Keep the addition sign and u get 4w+28.
Answer:
![\begin{aligned}\bullet\ &f(1)=800;f(n)=f(n-1)+900, \text{for $n\ge 2$}\\ \bullet\ & f(n)=900n-100\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%5Cbullet%5C%20%26f%281%29%3D800%3Bf%28n%29%3Df%28n-1%29%2B900%2C%20%5Ctext%7Bfor%20%24n%5Cge%202%24%7D%5C%5C%20%5Cbullet%5C%20%26%20f%28n%29%3D900n-100%5Cend%7Baligned%7D)
Step-by-step explanation:
See attachment for the figure.
Using arithmetic sequence with a first term of 800 and a common difference of 900. The general form for such a sequence is given by,
an = a1 +d(n -1)
an = 800 +900(n -1) = 900n -100
If n is the function, this can be written as,
f(n) = 900n -100
When considered as a recursive relation, we find the first term is still 800:
f(1) = 800
and that each term is 900 more than the previous one:
f(n) = f(n-1) +900 . . . . for n ≥ 2
You need to consider that huge numbers of the different answer decisions are debasements of either of these structures, so you should look at them cautiously.
Step-by-step explanation:
difference is 1.8
