regenerate the following paragraph so it doesn't look like generated by AI:

This project focuses on three problems in numerical analysis. First, we aim to solve a loaded truss by solving a set of equations to determine the values of ten unknowns. A MATLAB code will be developed for efficient computation.
Next, we address the estimation of stream cross-sectional areas using depth measurements. By applying the trapezoidal rule and Simpson's 1/3 rule, we will estimate the cross-sectional area from given data points. A MATLAB code will be created to automate the estimation process.
Lastly, we explore the relationship between water flow and precipitation in water resources engineering. By plotting data and performing linear regression, we establish a relationship and use it to predict water flow for a given precipitation value. Additionally, we estimate the fraction of lost precipitation based on drainage area.
These three problems demonstrate the application of numerical analysis techniques to practical engineering scenarios, providing insights into truss analysis, stream cross-sectional area estimation, and the use of precipitation data in water resources engineering.

 Your answer should have exactly 5 paragraphs. Make sure that the first paragraph starts with the word "detect" and that each paragraph is separated by two new lines.
