Questions 1-5 are listed by screenshots | Screenshots_1 - Screenshots_5

Question 4
Vector a is expressed in magnitude and direction form as ->a =⟨√26,140∘⟩.
What is the component form ->a?
Enter your answer, rounded to the nearest hundredth, by filling in the boxes.
->a = ⟨?⟩

Question 6
->a = ⟨−3,−5⟩ and -> b=⟨1,4⟩.
Represent ->a + ->b using the parallelogram method.
Use the Vector tool to draw the vectors, complete the parallelogram method, and draw ->a + ->b

Question 7
Michael plots the point with the polar coordinates (−2,−4π/3).
How does he plot this point?
Drag a value or phrase into each box to correctly complete the statements.
Michael first determines which line the angle of rotation places the point on. This line tells Michael that the point must lie in ? area if r is positive or ? area if r is negative. The radius of 2 tells Michael that the point lies on the second circle of the polar plane. The value of r is negative. Therefore, the point will lie ? area the angle of rotation.
