Given segment AB with points (-4, 8) and (6, 3) respectively. Find the coordinates of point P that partitions Segment AB in the

netineya [11]

Answer:

$P = (2,5)$

Step-by-step explanation:

Given

$A(-4,8)$

$B(6,3)$

$m:n = 3 : 2$

Required

Determine P

Since P divides the segment into 3:2, P is calculated using

$P = (\frac{nx_1 +m x_2}{m+n},\frac{ny_1 + my_2}{m+n})$

Where

$(x_1,y_1) = (-4,8)$

$(x_2,y_2) = (6,3)$

$m:n = 3 : 2$

Substitute these values in the above formula:

$P = (\frac{2 * -4 +3 * 6}{3 + 2},\frac{2 * 8 + 3 * 3}{3 + 2})$

$P = (\frac{-8 +18}{3 + 2},\frac{16 + 9}{3 + 2})$

$P = (\frac{10}{5},\frac{25}{5})$

$P = (2,5)$

The cost of 5 pounds of boudin is $26.What is the constant of proportionality that relates the cost in dollars,y, to the number

Ymorist [56]

Given :

The cost of 5 pounds of boudin is $26.

To Find :

The constant of proportionality that relates the cost in dollars y, to the number of pounds of boudin x .

Solution :

Price per boudin in terms of x and y is :

$P=\dfrac{y}{x}$

Price per boudin by given data :

$P=\dfrac{26}{5}$

So,

$\dfrac{y}{x}=\dfrac{26}{5}\\\\y = \dfrac{26}{5}x$

Therefore, the constant of proportionality is $\dfrac{26}{5}$ .

Hence, this is the required solution.
