For the answer to the question above asking to f<span>ind the coordinates of Z without using any new variables. 
</span>

Vector WZ equals vector VP, which is (p, -q) 
So Z is (-p - r + p, q - q) which is (-r, 0)
I hope my answer helped you.

Answer:

The coordinates are (-r,0)

Step-by-step explanation:

Given the coordinates of parallelogram PVWZ are P(0,0), V(-p,q), and W(-p-r, q). we have to find the coordinates of Z.

Let coordinates of Z(x,y)

As the diagonals of parallelogram bisect each other.

Therefore, by using mid-point formula

If (x_1,y_1)\text{ and }(x_2,y_2) \text{ are the coordinates of line segment the coordinates of mid-point are}

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

Mid-point of line segment joining the line P(0,0) and W(-p-r, q).

(\frac{-p-r}{2},\frac{q}{2})

Mid-point of line segment joining the line V(-p, q) and Z(x,y)

(\frac{-p+x}{2},\frac{q+y}{2})

As the diagonals of parallelogram bisect each other.

(\frac{-p-r}{2},\frac{q}{2})=(\frac{-p+x}{2},\frac{q+y}{2})

Comparing, we get

\frac{-p+x}{2}=\frac{-p-r}{2}

x=-r

\frac{q}{2}=\frac{q+y}{2}

y=0

Hence, the coordinates are (-r,0)

Bamboo Plant A is 1.2 meters tall and growing at a rate of 0.45 meter per day. Bamboo Plant B is 0.85 meter tall and growing 0.5
pashok25 [27]

Answer:

7 days

Step-by-step explanation:

Bamboo plant A = 1.2 + 0.45d

Bamboo plant B = 0.85 + 0.5d

Where,

d = number of days

Equate the two growth

Bamboo plant A = Bamboo plant B

1.2 + 0.45d = 0.85 + 0.5d

Collect like terms

1.2 - 0.85 = 0.5d - 0.45d

0.35 = 0.05d

Divide both sides by 0.05

d = 0.35 / 0.05

d = 7 days

Plant B be taller than Plant A after 7 days
