Answer:
62
Step-by-step explanation:
1. Divide the shape into 3 individual shapes.
2. To get the area you must multiply the width and the length.
3. Let's gather the width and the length of each shape.
Shape 1: 7 and 8
Shape 2: 2 and 3
Shape 3: 2 and 3
4. For Shape 1: 7 times 8 is 56.
5. Shape 2 and Shape 3 are equal to each other.
6. For Shape 2 + Shape 3: 2 times 3 is 6
7. Now you must add the area of all the shapes together.
Area of Shape 1: 56
Area of Shape 2: 3
Area of Shape 3: 3
8. 56 + 3 + 3 = 62
This means the area of the shape is 62.
Refer to the figure below.
Define unit vectors as follows:
in the eastern direction
in the northern direction
Given:
Vectors a and b point due west and south respectively. Therefore
Part (a)
The magnitude is
|-69(√[1² + 1²])| = 69√2 = 97.58.
The direction relative to west is
θ = tan⁻¹ (b/a) = tan⁻¹ 1 = 45° south of west
Answer:
The magnitude of (a + b) is 97.58 or 69√2.
The direction is 45° south of west.
Part (b).
The magnitude is
|69(√(1+1)| = 69√2 = 97.58.
The direction relative to west is
tan⁻¹ (b/a) = 45° north of west.
Answer:
The magnitude of (a-b) is 97.58 or 69√2.
The direction is 45° north of west.
