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 66% of $1,678.89 plus 7.5% tax?

schepotkina [342]

50% of 1,678.89 = 839.445
10% = 167.889
5% = 83.9445
1% = 16.7889
.5% = 8.39445
Therefore 66% = 1108.0674
and 7.5% = 125.91675
So the two added together is: 1233.98415
To get the percentages simply do the following
50% = divide by two
10% = divide 50% by five OR divide the original number by 10
5% = divide 10% by two or divide 50% by 10
1% = divide 5% by 5 or divide original by 100
.5% = divide 1% by two
