Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
This is a calculus 3 problem. Please explain each step clearly, no cursive writing.
![**Evaluate the double integral**
\[
\int \int_{R} e^{3x+y} dA
\]
**where** \( R = \{ (x, y) | 0 \leq x \leq 2, 0 \leq y \leq 2 \} \)
### Double Integral
### Plot of integrand and Region R
The image includes a 3D plot of the function \( z = e^{3x+y} \) over the region \( R \). The graph is a surface that curves upwards, increasing as both \( x \) and \( y \) increase, demonstrating the exponential nature of the function.
- **Axes:**
- \( x \)-axis is labeled from -2 to 2.
- \( y \)-axis is labeled from -2 to 2.
- \( z \)-axis shows values ranging from approximately 0 to 50.
The yellow shaded region represents where the function is evaluated within the bounds of \( x \) and \( y \).
**Note:** This plot is an example of the function over region \( R \). The region and function identified in your problem will be slightly different.
