Answer:

z = (6,-1)

Step-by-step explanation:

The missing parameters are:

x = (3,-1)

y = (3,5)

yz= \sqrt{45 --- Hypotenuse

Required

The coordinate of Z

First, calculate the distance xy

xy = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}

xy = \sqrt{(3 - 3)^2 + (-1 - 5)^2}

xy = \sqrt{0 + 36}

xy = \sqrt{36}

xy = 6

By Pythagoras theorem, distance xz is:

yz^2 = xz^2 + xy^2

(\sqrt 45)^2 = xz^2 + 6^2

45 = xz^2 + 36

Collect like terms

xz^2 =45-36

xz^2 =9

xz = \sqrt{9}

xz = 3

This means that z is 3 units to the right of x

We have:

x = (3,-1)

The rule to determine z is:

(x,y) \to (x + 3, y)

So, we have:

z = (3 + 3,-1)

z = (6,-1)

A team won 9 of its first 12 games. At that rate, how many games will the team win if it plays 64 games in all?
Feliz [49]
9 out of 12 = 9/12 which can be simplified to 3/4.  So the team wins 3/4 of its games.  3/4 of 64 = 64 divided by 4 = 16.  16 x 3 = 48.
