The endpoints of a side of rectangle ABCD in the coordinate plane are at A (1, 11) and B (3, 1). Find the equation of the line t

german

Answer:

Coordinates of vertices of rectangle A B CD are A(1,11), B(3,1).

Equation of line AB is

$\frac{y-1}{x-3}=\frac{1-11}{3-1}$

$\frac{y-1}{x-3}=-10/2$

⇒y-1=-5(x-3)

⇒y-1= -5 x+15

⇒y+ 5 x=1+15

⇒y+5 x=16→[ Equation of line that contains line segment AB]

Equation of line perpendicular to AB is

x- 5 y +k=0

Since it passes through A(1,11).

1-5×11+k=0

1-55+k=0

k-54=0

k=54

So equation of AB is

x-5 y+ 54=0

So equation of line, containing line segment AD is

→x-5 y+54=0

You are a sportswriter for a newspaper. Today you are writing an article about a professional basketball player. During the play

Paha777 [63]

For this case we can make the following rule of three:
1507 ----> 100%
1213 ----> x
Clearing the value of x we have:
x = (1213/1507) * (100)
x = 80.4910418
Rounding off we have:
x = 80.5%
Answer:
this player has made 80.5% of free throws
