The value of double integration can be found by applying limits and integrating them one by one.
<h3>What is integration?</h3>
It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.
We have:
![\rm \int\limits \int\limits_R {ye^{-xy}} \, dA \ , R = [0,2]\times[0,3]](https://tex.z-dn.net/?f=%5Crm%20%5Cint%5Climits%20%5Cint%5Climits_R%20%7Bye%5E%7B-xy%7D%7D%20%5C%2C%20dA%20%5C%20%2C%20R%20%3D%20%5B0%2C2%5D%5Ctimes%5B0%2C3%5D)
After plugging limits:

After solving the first integration:

After solving the further integration and plugging limits:


Thus, the value of double integration can be found by applying limits and integrating them one by one.

Step-by-step explanation:
a)
8÷2=4
12÷3=4
27÷9=3
•it does'nt always take the same amount of time to serve each customer .
•10×3=30
b)
according to the question
2=18 point
4=36 point
8=72 point
18=9×2
36=9×4
72=9×8
so 1dollar =9point
•each dollar spent appears to earn the same number of point
•because 81=9×9, it costs 9 dollar
Answer:
D. 159
Step-by-step explanation:
1 = 100%
1/4 = 0.25 = 25/100 = 25%
100 + 25 = 125
125% is your answer
hope this helps
