The coordinates a(0, 0), b(0, 3), c(4, 3), and d(4, 0) are graphed and connected together. what 3-dimensional shape will be created when this shape is rotated about the y-axis?

Find the x-intercepts of the parabola withvertex (1,1) and y-intercept (0,-3).write your answer in this form: (x1,if necessary, round to the nearest hundredth.

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

Cos^2x+cos^2(120°+x)+cos^2(120°-x)i need this asap. pls me
