(20 points)part2; the nth term of an arithmetic sequence is given by a_n=3n+2, write the first 4 terms and find the 8th partial sum. explain your answers! first five terms: 5th partial sum: first 4 terms: 8th partial sum:

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (-4, 0) and (6,0). the y-intercept of thefirst parabola is (0, –12). the y-intercept of the second parabola is (0-24). what is the positive difference between the avalues for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth.
