Is there a picture to this????

if your just asking how to find the area of something all you need to do is multiply all the numbers together and the total is the area.

Answer:

Anna's walk as a vector representation is $80\cos 33^{\circ}\hat{i}+80 \sin33^{\circ}\hat{j}$ and refer attachment.

Step-by-step explanation:

Let the origin be the point 1 from where Ann start walking.

Ann walks 80 meters on a straight line 33° north of the east starting at point 1 as shown in figure below,

Resolving into the vectors, the vertical component will be 80Sin33° and Horizontal component will be 80Cos33° as shown in figure (2)

Ann walk as a vector representation is $80\cos 33^{\circ}\hat{i}+80 \sin33^{\circ}\hat{j}$

Thus, Anna's walk as a vector representation is $80\cos 33^{\circ}\hat{i}+80 \sin33^{\circ}\hat{j}$

Is 1/2+4/9 greater than 1

ladessa [460]

1/2 x 9/9 = 9/18
4/9 x 2/2 = 8/18

9/18 + 8/18 = 17/18

17/18 is less than 1

so your answer is false

hope this helps
