Point A is located at (3, 6) and point B is located at (10,−2) .

<u>Answer:</u>

(4.75, 4)

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

We are to find the coordinates of the point that partitions the directed line segment AB in 1:3 ration.

For this, we will use the following formula:

$x = x_1 + k(x_2 - x_1)$ , $y = y_1 + k(y_2-y_1)$

where $k$ is the ratio of the first segment to the whole line segment so in this case, it will $\frac{1}{4}$ .

So substituting the given values in the above formula to find the coordinates:

$x = 3 + \frac {1}{4} (10-3) = 4.75$

$y = 6 + \frac{1}{4} (-2-6) = 4$

Therefore, the coordinates of the point that partitions the directed line segment AB in a 1:3 ratio are (4.75, 4).

Your team wins 18 medals at a competition. The metals are gold, silver, and bronze in a ratio of 2:4:3. How many of each metal d

Anarel [89]

Answer

Find out the how many of each metal did your team win.

To prove

As given

Your team wins 18 medals at a competition.

The metals are gold, silver, and bronze in a ratio of 2:4:3.

Let us assume that x be the scalar multiple of the gold, silver and bronze medal.

Thus

Number of gold medal = 2x

Number of silver medal = 4x

Number of bronze medal = 3x

Than the equation becomes

2x + 4x + 3x = 18

9x = 18

$x = \frac{18}{9}$

x = 2

Number of gold medal = 2 × 2

= 4

Number of silver medal = 4 × 2

= 8

Number of bronze medal = 3 × 2

= 6

Therefore the number of gold medal are 4, silver medal are 8, bronze medal are 6.

For a translation 4 units down you would subtract 4 from each y value and 5 units right you would add 5 to each x value.
Your resulting points would be.
A'(-1,1), B'(-1,-2), C'(3,-2), D'(3,2)
