Given that P = (-4, 11) and Q = (-5, 8), find the component form and magnitude of vector QP

Svetach [21]

The given points are
P = (-4,11)
Q = (-5,8)

The x-component of vector QP is
-4 - (-5) = 1
The y-component of vector QP is
11 - 8 = 3

The vector QP is
(1,3) or
$\vec{QP} = \hat{i} + 3\hat{j}$

The magnitude of the vector is
√(1² + 3²) = √(10)

Answer:
$\vec{QP} = \hat{i}+3\hat{j} \,\, or \,\, (1,3)$
The magnitude is √(10).

What is 3/4 + 2/3 ???

erica [24]

To add fractions, first convert them to have equal denominators.

3/4= 9/12 (multiply both sides by 3)
2/3= 8/12 (multiply both sides by 4)

From here, add the numerators while keeping the denominator.
9/12+ 8/12= 17/12

Final answer: 17/12 or 1 5/12
