A segment with endpoints A (4, 2) and C (1, 5) is partitioned by a point B such that AB and BC form a 1:3 ratio. Find B.
Furkat [3]

The coordinates of point B that divides the line in the ratio 1:3 is: ( C )(3.25, 2.75)

<h3>What is a line segment?</h3>

A line segment is formed by joining two points by a straight line.

Analysis:

The coordinates of point B(x,y) are gotten by the formula

x = \frac{px2 + qx1}{p+q}

y = \frac{py2 + qy1}{p + q}

where, x1 and y1 are coordinates of A and x2 and y2 are coordinates of B

are the values of the ratio p:q.

x1 = 4, x2 = 1 y1 = 5,  y2 = 2, p = 1, q = 3

x = \frac{(1 x 1) + (3 x 4)}{1 + 3} = 3.25

y = \frac{(1 x 5) + ( 3 x 2)}{1+3} = 2.75

coordinates of B are ( 3.25, 2.75)

In conclusion, the coordinates of point B are (3.25, 2.75)

QUICK <br> What is the image point of (1,4) after a translation left 5 units and down 3 units ?
Lynna [10]

Answer:

(-4,1)

Step-by-step explanation:

First, subtract 1-5. (When you move left or down you subtract. When you move right or up you add.) Left and right affect the x-axis

Second, subtract 4-3. Up and down Affect the y-axis

It would look like this:

(1,4)

=(1-5,4-3)

=(-4,1)

A certain club has 10 members, including Harry. One of the 10 members is to be chosen at random to be the president, one of the
WINSTONCH [101]

Answer:

(E) 1/5

Step-by-step explanation:

The probability that Harry will be chosen to be the secretary but not the president is \frac{9}{10} *\frac{1}{9} =\frac{1}{10}

The probability that Harry will be chosen to be the treasurer but not the president or secretary is \frac{9}{10} *\frac{8}{9}*\frac{1}{8}=\frac{1}{10}

Thus, the probability that Harry will be either the member chosen to be the secretary or the member chosen to be the treasurer is \frac{1}{10} + \frac{1}{10} = \frac{1}{5}
