What are the coordinates of the point on the directed line segment from (-9, -1)(−9,−1) to (-9, -10)(−9,−10) that partitions the

mihalych1998 [28]

Answer:

Therefore the co-ordinate of the point on the line segment from (-9,-1) to(-9,-10) into a ratio internally is (-9,-7).

Therefore the co-ordinate of the point on the line segment from (-9,-1) to(-9,-10) into a ratio internally is (-9,-19).

Step-by-step explanation:

Given points are (-9,-1) and (-9,-10)

If a point divides the line segment by joining two points (x₁,y₁) and (x₂,y₂) into a ratio m:n internally.

Then the point of the coordinate is $(\frac{m.x_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})$ .

If a line segment is externally divided into a point by joining two points (x₁,y₁) and (x₂,y₂) with m: n ratio.

Then the point of the coordinate is $(\frac{m.x_2-nx_1}{m-n},\frac{my_2-ny_1}{m-n})$ .

Internally

The co-ordinate of the point is $(\frac{(-9)\times2+(-9)\times 1}{2+1},\frac{(-10)\times 2+(-1)\times 1}{2+1})$

$=(-9,-7)$

Externally

The co-ordinate of the point is $(\frac{(-9)\times2-(-9)\times 1}{2-1},\frac{(-10)\times 2-(-1)\times 1}{2-1})$

= (-9,-19)

A person has body fat percentage of 17.2% and weighs 171 pound how many pounds of her weight is made up of fat

Citrus2011 [14]

Answer: 29.41 pounds

Step-by-step explanation:

You have the following information given in the problem:

- The fat percentage that the person has is 17.2%

- The person weighs 171 pounds.

Therefore, to calculate the amount of pounds of her weight is made up of fat (which you can call x), you must multiply the weight of the person by the fat percentage.

Therefore, you obtain the following result:

$x=171lb*0.172\\x=29.41lb$
