I NEED A STEP-BY-STEP SOLUTION FOR EVERY PROBLEM

2' A line segment has endpoints A{2, 0) and 3(6, 5). What is the measure of the angle 9 formed by the line segment and the :raxis? Explain how you found the measure of the angle. 3' Use residuals to examine if the model at) 2 4:5 5 is a good t for the data in the table below. Explain each step. -I I-Inl 4- Use the matrices Pa :1 H; 2] es 3 to determine whether the expressions (P + QUE and PR + QR are equal. Explain each step. 5' Find a: for which log, log (2\": 1), and log (2\" | 3) are three consecutive terms of the arithmetic sequence
