A sequence is defined as: a\/2=5 a\/n=a\/n-1+4. What is the value of a\/6?

Which statement best describes the expression 4y ÷ 9? (1 point) 9 divided by 4 times y 9 times y divided by 4 4 times y divided by 9 4 divided by 9 times y

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Find the volume of the solid obtained by rotating the region enclosed by the curves y=1x and y=7^-x about the x-axis. (use symbolic notation and fractions where needed.) volume =
