What is the exact distance between the point (-2,-1) and the point (6,8) units

Mathematics
1 answer:
Studentka2010 [4]4 years ago
4 0

Answer:

\sqrt{145}units

Step-by-step explanation:

Distance between 2 points

= \sqrt{(x1 - x2)^{2}  + (y1 - y2)^{2} }

Thus distance between (-2, -1) and (6, 8)

= \sqrt{ {(6  + 2)}^{2}  + (8 + 1)^{2} }  \\  =  \sqrt{8^{2}  + 9^{2} }  \\  =  \sqrt{145}  \: units

The ratio of the number of cups of yellow paint to the number of cups of blue paint that Greg mixed to make a shade of green pai
ziro4ka [17]

Answer:

Part A:  A ratio of 2:1  means that he uses<u><em> </em></u><u><em>2 cups of yellow paint for each cup of blue paint.</em></u>

-------------------------------------------------------------------------------------------------

Part B: The ratio of yellow to blue is 2:1 = 2/1. So, if for 2 yellow is 1 blue, then for 1 yellow is x:

2/1 = 1/x

x = (1*1) / 2

x = 1/2

<u><em>For each cup of yellow paint, Greg should add 1/2 cup of blue paint.</em></u>

<u><em></em></u>

-------------------------------------------------------------------------------------------------

 Part C: 6 cups cost $54, then 1 cup cost:

54 / 6 = 9

<u><em>The price per cup of yellow paint is $9.</em></u>

<u><em></em></u>

Find the midpoint of the segment with the following endpoints.<br> (4, 2) and (7, 6)
Artist 52 [7]

The midpoint of the segment with the following endpoints, (4, 2) and
(7, 6) is (5.5, 4).

How to determine the midpoint of a given segment?
The center point of a straight line can be located using the midpoint formula. We can use this midpoint formula to determine the coordinates of the supplied line's midpoint in order to discover its location on a graph. Assuming that the line's endpoints are (x₁, y₁) and (x₂, y₂), the midpoint (a, b) is determined using the following formula:
(a , b) ≡ (((x₁ + x₂)/2), ((y₁ + y₂)/2))

Let the line segment be AB having endpoints as A(4, 2) and B(7, 6);
also let the co-ordinates of midpoint be C = (a, b)
Using the given formula in the available literature,
(a, b) = ((4 + 7)/2, (2 + 6)/2)
Equating parts of the previous equation, we get,
a = (4 + 7)/2 = 11/2 = 5.5
b = (2 + 6)/2 = 4
Thus, the midpoint of the segment is (5.5, 4).
