2. Equals 307.629 because if you line up the decimals when you and then you should get your right answer
Answer:
-13
Step-by-step explanation:
Plug in 10 as x into the function:
f(x) = -2x + 7
f(10) = -2(10) + 7
f(10) = -20 + 7
f(10) = -13
So, f(10) = -13
Joanna deposited $132000 and her interest amount is $359730.35
<u>Step-by-step explanation:</u>
Monthly deposit = $275
Interest = 5.6%
Time = 40 years
After 40 years her account balance = $491730.35
If she deposit $275 monthly then after 40 years she will have deposited ,
= 275 x 12 x 40
= $132000
The remaining is her interest amount.
Interest amount = 491730.35 - 132000
= $359730.35
Joanna deposited $132000 and her interest amount is $359730.35
The general term is

(a sub n; n is a subscript)
The first term is a1
The second term is a2
The third term is a3
and so on...
The first term starts at n = 1. We replace the n in

with 1 to get

. A similar thing happens with n = 2 and onward
The domain is therefore the set {1, 2, 3, 4, 5, ...} which is the set of...
* Counting numbers
* Positive Whole numbers
* Natural numbers
Those are three ways to express the same set
We can also say

where n is an integer or whole number
A similar inequality would be

which is effectively the same as idea as the last inequality (n is also an integer or whole number).
