point b, o, and y are collinear on by, and bo:oy = 5/8. B is located at (4,2,) o is located at (57/8,-3) and Y is located at (x,
Lena [83]

Given: BO : OY = 5:8. Coordinate B is located at (4,2,) ; O is located at (57/8,-3) and Y is located at (x,y).

We have to determine the coordinate Y.

We will use cross section formula which states:

The coordinates (x_1,y_1) , (x_2,y_2) are divided in the ratio m_1 : m_2 by the Coordinate A. So, the coordinates of A are given by the formula:

(\frac{m_1x_2+m_2x_1}{m_1+m_2} , \frac{m_1y_2+m_2y_1}{m_1+m_2})

Here, \frac{57}{8} = \frac{5x+(8 \times 4)}{5+8}

\frac{13 \times 57}{8} = 5x+32

\frac{741}{8} = 5x+32

5x= 60.625

x = 12.125

Now, -3=\frac{5y+(8 \times 2)}{5+8}

-39 = 5y+16

-55 = 5y

y = -11

So, the coordinate is Y(12.125, -11).

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
slamgirl [31]

x = Alicia's age

Amy is 8 years older than twice her cousin Alicia's age so Amy's age = 2x + 8

Sum of their ages is less than 32

x + 2x + 8 < 32

3x + 8 < 32

3x < 24

x < 8

So Alicia's age is greater than 0 but less than 8 years old

(0 < x < 8)

Answer:

A) 0 < x < 8

What is the simplest form of 1.764?
Agata [3.3K]

Answer:

1764 = 2^2 \times 3^2 \times 7^2

Step-by-step explanation:

Divide by the prime numbers in increasing order until you find all the prime factors.

The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17

1764/2 = 882

882/2 = 441

441/3 = 147

147/3 = 49

49/7 = 7

7/7 = 1

1764 = 2^2 \times 3^2 \times 7^2
