Hi guys, Can anyone help me with this line integral?

Look at this pattern ; 1,4,9, number 10000 belongs in this pattern . what’s the place of this number?

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

Yvaries directly as x. y =90 when x=6. find y when x=13
