Sketch the following curves. (a) r = (1 − t)(i + j) + t(i − j); 0 ≤ t ≤ 1
(b) r(t) = ⟨t^4 + 1, t⟩.

Can anyone please help me sketch this graph?

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000
