what is the power series representation of g(x)=ln(1-7x)? Include the first four nonzero terms and the interval of convergence.

Use the method of cylindrical shells to find the volume v generated by rotating the region bounded by the curves about the given axis.y = 7ex, y = 7e^-x, x = 1; about the y-axis

Myra took a picture of the sky one afternoon when two jet airplanes appeared to draw a pair of parallel lines with their vapor trails. the vapor trails from two other jets flying from another direction crossed over the parallel trails. she printed her picture and labeled the angles and lines. assume lines c and d are parallel and 2 measures 98°. which statements are true? check all that apply. 3 = 6 = 98° 3 = 14 = 98° 4 = 8 = 82° 4 = 12 = 82° 5 = 8 = 82°

If f(x)= x^2 - 4 and g(x)=x^2 + 2 x, (b). (f-g)(x) i think i know the 1st 2 steps: f(x)-g(x) x^2-4 - x^2+2x
