The three vertices of a triangle are located at A (6, -1, 2), B (-2, 3, -4), and C(-3, 1, 5). Find: (a) RE X RAci

The distance from the point (-8,-7,-2) to the yz plane is: ?

Given: R is the midpoint of QS, ZRPQ =ZRTS prove: APQR = ATSR P.

Please Show the solutions... Thank you!

Consider the parametric curve C given by x = sin-'(5) = 2/4– t² where t e (-2, 2]. (a) Determine the values of t where C has horizontal and vertical tangent lines. (b) Set up, but do not evaluate the integral equal to the length of the arc of C from the point (0, 4) to the point (5,0).
