What is the length and width of a room that is 60 square meters and has a perimeter of 32 meters
AleksAgata [21]
L = lenght
W = width

L * W = 60 \\&#10;2L + 2W=32\\\\&#10;L = \frac{32-2W}{2}\\&#10;\frac{32-2W}{2}*W = 60\\&#10;(16-W)*W = 60\\&#10;-W^{2} + 16W -60 = 0\\\\&#10;&#10;d = 16^{2} - 4*1*60 =  256 - 240 = 16 \\\\&#10;W1 = \frac{-16+\sqrt{16}}{-2} =  \frac{-12}{-2} = 6\\&#10;W2 = \frac{-16-\sqrt{16}}{-2} =  \frac{-20}{-2} = 10\\&#10;&#10;L1 = 10\\&#10;L2 = 6\\&#10;

so

{L,W} = {6,10} or {10,6}

but L > W  so

L = 10
W = 6

Directed line segment has endpoints P(– 8, – 4) and Q(4, 12). Determine the point that partitions the directed line segment in a
larisa86 [58]

Answer:

Point (1,8)  

Step-by-step explanation:

We will use segment formula to find the coordinates of point that will partition our line segment PQ in a ratio 3:1.

When a point divides any segment internally in the ratio m:n, the formula is:

[x=\frac{mx_2+nx_1}{m+n},y= \frac{my_2+ny_1}{m+n}]

Let us substitute coordinates of point P and Q as:

x_1=-8,

y_1=-4

x_2=4

y_2=12

m=3

n=1

[x=\frac{(3*4)+(1*-8)}{3+1},y=\frac{(3*12)+(1*-4)}{3+1}]

[x=\frac{12-8}{4},y=\frac{36-4}{4}]

[x=\frac{4}{4},y=\frac{32}{4}]

[x=1,y=8]

Therefore, point (1,8) will partition the directed line segment PQ in a ratio 3:1.
