kondaur [170]

Given

.OABC is a tetrahedron

OA=a, OB=b, and OC=c.

point P and Q are such that OA =AP and 2OB = BQ

point M is a midpoint of PQ.

Find AB ,PQ, CQ ,QM ,MB ,OM in terms of a, b, and c.

To proof

we proof this by using the Triangle law of vector addition

when two vectors are represented by two sides of a triangle in magnitude and direction taken in same order then third side of the third side of that triangle represents in magnitude and direction the resultant of the vectors.

by using the diagram as shown below

 \vec{OA}=\vec{a}, \vec{OB}=\vec{b}\\\vec{OP}=2\vec{a},\vec{OQ}=3\vec{b}

\vec{OA}+\vec{AB}=\vec{OB}\\\vec{AB}=\vec{b}-\vec{a}

\vec{OP}+\vec{PQ}=\vec{OQ}\\\vec{PQ}=3\vec{b}-2\vec{a}

\vec{OC}+\vec{CQ}=\vec{OQ}\\\vec{CQ}=3\vec{b}-2\vec{c}\\\vec{QM}=-\frac{1}{2}\vec{PQ}\\

\vec{QM}=\vec{a}-\frac{3}{2}\vec{b}\\\vec{OM}=\vec{OQ}+\vec{QM}

\vec{OM}=\vec{a}+\frac{3}{2}\vec{b}\\\vec{MB}=-\vec{a}-\frac{1}{2}\vec{b}

hence proved

Estimate the total percentage of complaints about parking difficulties and the location of the store. (nearest whole percent)
AysviL [449]

Answer:

Therefore the total  Complains about parking difficulties=32.26%

Therefore the total  Complains about the location of the store=25.81%

Step-by-step explanation:

Given ,

Complains about difficulty parking = 250

Complains about isolated location = 200

Complains about ruled sales clerks=150

Complains about too expensive=125

Complains about confusing layout= 50

Total complains = (250+200+150+125+50)

                          =775

Therefore the total  Complains about parking difficulties

=\frac{250}{775}\times 100 %

=32.26%

Therefore the total  Complains about the location of the store

=\frac{200}{775}\times 100 %

=25.81%
