Answer:

Option A. $(a/2,0)$

Step-by-step explanation:

we know that

If triangle ABC is a right isosceles triangle

then

AB=AC

m<ABC=m<ACB=45°

therefore

The coordinate of point C is $(a,0)$

the x-coordinate of the midpoint M is equal to

$(0+a)/2=a/2$

The coordinates of point M are $(a/2,0)$

salantis [7]

The ratio between the departments is

A: B: C
15000 : 18000 : 9000
15 : 18 : 9
5 : 6 : 3

The budget needs to be divided into 5+6+3 = 14 parts
The budget for one part is 22000/14

The budget for department B is $\frac{22000}{14}*6=9428.571428$

drek231 [11]

<h2>Answer:</h2>

Four points are always coplanar if:

A. They lie in the same plane.

C. all of them are collinear.

<h2>Step-by-step explanation:</h2>

<u>Coplanar--</u>

The points are said to be coplanar if all of them lie in the same plane.

<u>Collinear-</u>

The points are said to be collinear if all of them lie on a straight line.

Also as we know that a line always lie in one plane and so all the points that lie on that line will also lie in the same plane.

Hence, we may say that Four points will be coplanar if all of them are collinear.

Hence, the correct options are:

Option: A and Option: C
