Find the exact distance between (5, 3) and (-2, 8).

Brrunno [24]

Answer:

The answer is

<h2> $\sqrt{74} \: \: \: \: units \\$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

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

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(5, 3) and (-2, 8)

The distance between them is

$d = \sqrt{( {5 + 2})^{2} + ( {3 - 8})^{2} } \\ = \sqrt{ {7}^{2} + ({ - 5})^{2} } \\ = \sqrt{49 + 25} \\ = \sqrt{74} \: \: \: \: \: \: \: \: \: \:$

We have the final answer as

$\sqrt{74} \: \: \: \: units \\$

Hope this helps you

Answer:

$7.10

Step-by-step explanation:

Nevach's rate can be found by using x=1 in the equation for his pay.

y = 28.5 × 1 = 28.50 . . . . dollars

Carson's hourly rate can be found by dividing dollars by hours:

$214/(10 h) = $21.40/h

Nevach's rate exceeds this by ...

$28.40 -21.40 = $7.10

Nevach earns $7.10 more per hour.
