Let s be the portion of the plane with equation x+y−z+ 3 = 0 that lies above the rectangle determined by 1 ≤ x ≤ 4 and 2 ≤ y ≤ 5
(a) sketch s.
(b) find the surface area of the surface s by taking an appropriate cross product.
(c) find the surface area of the surface s by using the material of §15.5.

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

1010: 3030

is it i think

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
