Find the distance between the points (5, -3) and (0, 2).
ohaa [14]

Answer:

Distance between points  (5, -3) and (0, 2) is √50 or 7.07

Step-by-step explanation:

We need to find distance between two points (5,-3) and (0,2)

The distance formula used is:

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

here

x₁= 5, y₁=-3, x₂=0 and y₂=2

Putting values in the formula:

d= \sqrt {\left( {x_2-x_1} \right)^2 + \left( {y_2-y_1} \right)^2 }\\d= \sqrt {\left( {0-5} \right)^2 + \left( {2-(-3)} \right)^2 }\\d= \sqrt {\left( {-5} \right)^2 + \left( {2+3} \right)^2 }\\d= \sqrt {25+25}\\d= \sqrt {50}\\d= 7.07

So, distance between points  (5, -3) and (0, 2) is √50 or 7.07

A property contained ten acres. How many lots of not less than 50 feet by 100 feet can be subdivided from the property if 26,000
NemiM [27]

Answer:

81 lots of 5,000 square feet fits in the property.

Step-by-step explanation:

<em><u>The first step </u></em>is calculate the square feet of the minimum area:

50 \: feets \times 100 \: feet = 5,000 \:square \: feet

<em><u>Second,</u></em> from the ten acres we subtract the 26,000 feets of roads:

1 \: acre = 60 \: feet \times 660\:feet = 43,560\:square\:feet\\43,560 \times 10 = 435,600\\435,600 - 26,000 = 409,600 \:square \: feet\:available

<em><u>Third,</u></em> we divide the lot area over the available square feet

\frac{409,600}{5,000} = 81.92

81 lots of 5,000 square feet fits in the property.
