How do i find the correlation coefficient of a data table?

Josephine has a great garden with and area of 2x2 + x - 6 square feet

Find the volume of the described solid. the solid lies between planes perpendicular to the x-axis at x = 0 and x=7. the cross sectionsperpendicular to the x-axis between these planes are squares whose bases run from the parabolay=-31x to the parabola y = 30/x. a) 441b) 147c) 864d) 882

Write the expression as a single natural logarithm. 2 in a - 4 in y
