Create three types of scatter plots. Part A) --> 1) A scatter plot with a positive association. 2) A scatter plot with a negative association. 3) A scatter plot with no association. ( I posted a picture of Part B). Will Mark Brainliest To whoever can help and show there work.

What is the axis of symmetry of the function f(x)=-(x+ 9)(x-21)

Find the volume of the solid whose base is the region bounded by f(x), g(x) and the x-axis on the interval [0, 1], and whose cross-sections perpendicular to the y-axis are squares. your work must show the integral, but you may use your calculator to evaluate it. give 3 decimal places for your answe

Which expressions equal 9 when x=4 and y=1/3 a. x2+6y b. 2x + 3y c. y2-21x d. 5 (x/2) -3y e. 3x-9y
