Answer:

Scalene triangle

Step-by-step explanation:

Coordinates of the vertices of the triangle are,

W(-7, 1), X(0, -4) and Y(2, 3)

We will use the formula to get the distance between two points.

d = \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

WX = \sqrt{(-4-1)^2+(0+7)^2}

      = \sqrt{74}

WY = \sqrt{(1-3)^2+(-7-2)^2}

      = \sqrt{85}

XY = \sqrt{(3+4)^2+(2-0)^2}

     = \sqrt{49+4}

     = \sqrt{53}

Since, measures of all three sides of the triangle are not equal, given triangle will be a scalene triangle.

In how many ways can a committee of 3 men and 2 women be formed from a group of 9 men and 10 ​women?
Setler [38]

Answer:

first you have to find the number of ways 3 men can be chosen, then the number of ways 2 women can be chosen, and then you need to multiply these numbers together to get the number of ways because multiplication will show the total arrangements possibilities. use combination since order does not matter.

number ways for 2 out of 10 women total: 10 choose 2= 45

number of ways for 3 out of 9 men total: 9 choose 3= 84

84x45= 3780

3780 total ways

number of ways

I need to make a matrix in reduced row echelon form
a_sh-v [17]

Let the three apartments be A, B & C

The rent of A is $x

The rent of B is $y

The rent of C is $z

So x + y + z = 1600     .......(1)

Now

Maintenance of A is 20% of x = 0.20x

Maintenance of B is 20% of y = 0.20y

Maintenance of C is 25% of z = 0.25z

0.20x + 0.20y + 0.25z = 345

Multiplying by 100 we get

20x + 20y + 25 z = 34500

Dividing by 5 we get

4x + 4y + 5z = 6900              .......(2)

Monthly fee of A is 10% of x = 0.10x

Monthly fee of B is 20% of y = 0.20 y

Monthly Fee of C is 10% of z = 0.10z

Now

0.10x + 0.20y + 0.10 z= 1820 - 1600

0.10x + 0.20y + 0.10z = 220

Multiplying by 100 we get

10x + 20y + 10z = 22000

Dividing by 10

x + 2y + z = 2200     ....(3)

Making a Matrix of equation (1), (2) & (3)

\left[\begin{array}{ccc}1&1&1\\4&4&5\\1&2&1\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right]  =\left[\begin{array}{c}1600\\6900\\2200\end{array}\right]

is the required matrix
