jenyasd209 [6]
The answer is $41.12
(Work is below)

First add the total of the vase and shipping-
Vase:                    $34.99
Shipping:              $   3.00
                         +__________
                             $37.99

Then calculate sales tax by multiplying $37.99 x 0.0825 -
Above Total:         $37.99
Sales Tax Rate:    $   0.0825
                         x__________
                              $  3.1341
You round down because ^ less than five (five or above you would round up)

Sales Tax:             $3.13

Then you add the sales tax to the above total

Vase:                    $37.99
Shipping:              $  3.13
                         +__________
                             $41.12

An isosceles triangle’s altitude will bisect its base. Which expression could be used to find the area of the isosceles triangle
omeli [17]

Answer:

\dfrac{\sqrt{40}\cdot \sqrt{40}}{2}

Step-by-step explanation:

The length of the base is the distance between the points 4+2i and 10+4i, so

\text{Base}=|10+4i-(4+2i)|=|10+4i-4-2i|=|6+2i|=\sqrt{6^2+2^2}=\\ \\=\sqrt{36+4}=\sqrt{40}

The middle point of the base is placed at point

\dfrac{4+2i+10+4i}{2}=\dfrac{6i+14}{2}=7+3i

The length of the height is the distance between the points 5+9i and 7+3i

\text{Height}=|5+9i-(7+3i)|=|5+9i-7-3i|=|-2+6i|=\sqrt{(-2)^2+6^2}=\\ \\=\sqrt{4+36}=\sqrt{40}

So, the area of the triangle is

A=\dfrac{1}{2}\cdot \text{Base}\cdot \text{Height}=\dfrac{\sqrt{40}\cdot \sqrt{40}}{2}
