Answer:
$6981
Step-by-step explanation:
Let's find the answer by using the following formula:
(this year cost)=(last year cost)+((last year cost)*(percent increase of cost)) so:
3750+3650=X+0.06X where X=last year cost, then:
7400=1.06X
6981.13=X
In conclusion, last year he spent $6981.
Integrate indefinite integral:

Solution:
1. use substitution
=>

=>

=>

=>


2. decompose into partial fractions


where A=1/2, B=1/2, C=-1

3. Substitute partial fractions and continue


4. back-substitute u=e^x


Note: log(x) stands for natural log, and NOT log10(x)
Step-by-step explanation:
1) A number <em>m</em> is at least four
<em>m ≥ 4 ['at least' = ≥ symbol]</em>
<em />
2) 4x ≤ 20x; x=2
4(2) ≤ 20(2)
8 ≤ 40
[Im not sure if this is a solution or and inequality :/ ]
3) x < 5
--> On the line, draw the number 0, and the number five. 'x < 5' also means 'x is less that five.' So, draw a dot over the line before 5, and make an arrow going to the left of the page,

Hopefully this helps! :)
