Consider parallelogram VWXY below.

olchik [2.2K]

note:Parallelogram WXYZ not VWXY & I will answer the questions in the image b'cos I don't get your question.

Answers:

a.(i.)Slope of line YZ = 4/5

(ii.)Line adjacent line YZ is line YX,slope of YX =5/4

b.(i.)Length of line YZ =√41 units

(ii.)Length of line YX =√41 units

c.WXYZ is a rhombus.

Step-by-step explanation:

a.Slope=gradient(m)=(y₂-y₁)/(x₂-x₁)

(i.)m of line YZ=(y₂-y₁)/(x₂-x₁) where Y(-6,-1) & Z(-1,3)

(I believe you know what the y₂,y₁,x₂ & x₁ stand for.)

So m=(y₂-y₁)/(x₂-x₁),=(3-(-1))/(-1-(-6) =(4)/(5)=4/5

∴m of line YZ is 4/5

(ii.)m of line YX=(y₂-y₁)/(x₂-x₁) where Y(-6,-1) & X(-2,4)

So m=(y₂-y₁)/(x₂-x₁),=(4-(-1))/(-2-(-6) =(5)/(4)=5/4=1.25

∴m of line YX is 5/4

b.(i.)To find the length of line YZ,we have to express it as column vector YZ.

Vector YZ=OZ-OY,Z-Y=(-1,3)-(-6,-1)=(5,4)

Length=√x² plus y²=√5² plus 4²=√25 plus 16=√41 units

∴The length of line YZ is √41 units.

(ii.)To find the length of line YX,we have to express it as column vector YZ.

Vector YX=OX-OY,X-Y=(-2,4)-(-6,-1)=(4,5)

Length=√x² plus y²=√4² plus 5²=√16 plus 25=√41 units

∴The length of line YX is √41 units.

c.WXYZ is a rhombus.

Find all polar coordinates of point p if p=1,-x/6

Alecsey [184]

Answer:

All polar coordinates of point P are; (1 , -x/6 + 2nn) and (-1, -x/6 + (2n+1)n)

Step-by-step explanation:

The polar coordinates can be represented as;

(r,Ф)= (r,Ф+2nn) or (r,Ф) =(-r,Ф+(2n+1)n)

Where n is any integer value.

From the question, we are given that; p=(1,-x/6)

Comparing it with P(r,Ф), then r = 1 and Ф = -x/6

The polar coordinates will now be;

P(r,Ф) = (r,Ф+2nn) = (1 , -x/6 + 2nn)

Where; n is any positive integer and the value of r is positive.

While;

P(r,Ф) =(-r,Ф+(2n+1)n) = (-1, -x/6+(2n+1)n) and n is any positive integer and the value of r is negative.

Thus, all polar coordinates of point P are (1 , -x/6 + 2nn) and (-1, -x/6 + (2n+1)n)

James and john shared 63 marbles in the ratio 4:5 how manzly marbles did john get

WITCHER [35]

So if the ratio is 4:5, we know that this total amount of marbles must first be split into 9 equal parts:

$\frac{63}{9}=7$

Now we know that each 'part' is going to be equal to 7 marbles.

So then in the ratio, we are simply going to multiply each side by 7:

$4:5=28:35$

Therefore, since John had the part of '5' in the ratio, the amount of marbles that John got was 35.
