Answer:

$497.90

Step-by-step explanation:

8.25% sales tax becomes 0.0825 as a decimal fraction.

Then the total cost would be $459.95 plus 0.0825($459.95), or, in more compact form,

Total Cost = (1.0825)($459.95) = $497.90

Answer:

$ge= \sqrt{74}$

Step-by-step explanation:

Given

$d = (-1,-1)$

$f =(4,-8)$

Required

Length of ge

The length of ge is the same as the length of df. So, we start by calculating distance gf

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

This gives:

$D = \sqrt{(-1-4)^2+(-1+8)^2}$

$D = \sqrt{(-5)^2+7^2}$

$D = \sqrt{74}$

This implies that:

$df = \sqrt{74}$

$ge= \sqrt{74}$
