Resolve the vector into components. 1. A vector starting at the point Q = (4, 6) and ending at the point P = (1, 2).
lesya692 [45]

Answer:

1. Horizontal component = -3 units

  Vertical component = -4 units

2. Horizontal component = 3 units

  Vertical component = 4 units

Step-by-step explanation:

If a vector M, starting at point A = (a, b) and ending at point B = (c, d) is given, then the vector can be resolved into x and y components as follows;

M = AB

Where;

AB = B - A

AB = (a, b) - (c, d)

AB = (a-c, b-d)

AB = (a-c)i + (b-d)k

<em>Therefore, </em><em>a-c </em><em>and </em><em>b-d</em><em> are the x and y components of the vector M.</em>

<em />

(1) Let the vector be M:

Starting point of M = Q = (4, 6)

Ending point of M = P = (1, 2)

So,

M = PQ

Where;

PQ = Q - P

PQ = (1,2) - (4,6)

PQ = (1-4, 2-6)  

PQ = (-3, -4)

Therefore,

M = PQ = -3i - 4j

The x and y components of M are therefore, -3 and -4 respectively.

(2) Let the vector be M:

Starting point of M = P = (1, 2)

Ending point of M = Q = (4, 6)

So,

M = PQ

Where;

PQ = Q - P

PQ = (4,6) - (1,2)

PQ = (4-1, 6-2)  

PQ = (3, 4)

Therefore,

M = PQ = 3i + 4j

The x and y components of M are therefore, 3 and 4 respectively.

<em>Note: The x and y components are also called the horizontal and vertical components respectively.</em>

SOMEONE HELP ASAP WHATS THE MISSING ANGLE
Lapatulllka [165]

Answer:

130

Step-by-step explanation:

? is an exterior angle of a triangle

An exterior angle is equal to the sum of the two opposite interior angles ( 35 and 95 in this case )

That being said the missing angle = 95 + 35

95 + 35 = 130

Hence, the answer is 130
