Answers

Answer 1
Answer:

Answer:

The estimation here will change as per the place value of the number.

The number is 229171.

This becomes 229,000 when rounded to the nearest 1,000 or the Thousands Place.

This becomes 230,000 when rounded to the nearest Ten Thousands Place.

And it becomes 200,000 when rounded to nearest Hundred Thousands Place.

What is the length side of a triangle that has vertices at (-5, -1), (-5, 5), and (3, -1)?

Answers

Answer: 6,8 and 10

Step-by-step explanation:

To find the length , all we need to find is the distance between each point ,

the formula for calculating distance between two points is given by :

D = \sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}

Let the points be :

A ( -5,-1)

B(-5,5)

C(3,-1)

Calculating the length AB , we have

D1 = \sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}

D1 = \sqrt{(-5+5)^(2)+(5+1)^(2)}

D1 = √(36)

D1= 6

Calculating the length AC , we have

D2 = \sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}

D2 = \sqrt{(3+5)^(2)+(-1+1)^(2)}

D2 = √(64)

D2 = 8

Calculating the length BC , we have

D3 = \sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}

D3 = \sqrt{(3+5)^(2)+(-1-5)^(2)}

D3 = √(100)

D3 = 10

Therefore ,the length of the sides of the triangle are 6,8 and 10

write the equation of the line that passes through the point (8,-1) and (2,-5) in standard form, givin that the point slope form is y + 1 = 2/3(x-8).​

Answers

Answer:

The line equation in standard form is 2x – 3y = 19.

Explanation:

Given:

The point (8,-1) and (2,-5) in standard form

The point slope form is y + 1 = 2/3(x-8).

To find:

Equation of the line

Solution:

Now, we have line equation in point slope form, we have to convert it into standard form i.e. ax + by = c

Then, let us simplify the above equation.  

y + 1 = (2)/(3) (x - 8)

3(y + 1) = 2(x – 8)  

3y + 3 = 2x – 16  

2x – 3y = 16 + 3  

2x – 3y = 19

Hence, the line equation in standard form is 2x – 3y = 19.
