Kite:

10.2 x 8 = 81.6/2 = 40.8 ft^2

pentagon:

area = 1/2 x apothem x perimeter
perimeter = length of side x number of sides

pentagon has 5 sides, perimeter = 5 *20 = 100

area = 1/2 x 14 x 100 = 700 in^2

Answer:

263.08 m²

Step-by-step explanation:

The fraction of circle area that a sector represents is proportional to the central angle.

<h3>Proportion</h3>

circle area/circle angle = sector area/sector angle

circle area / 360° = 85.5 m² / 117°

Multiplying by 360°, we have ...

circle area = (360/117)(85.5 m²) = 263.08 m²

The area of the circle is about 263.08 m².

Write the following as a root in radical form 2^-4/5

erastovalidia [21]

Answer:

Given that:

=2^(-4/5)

This means that 2 is the base and -4/5 is the exponent.

To change it in radical form:

firstly the denominator would be written with radical sign
Then the negative sign with 4 will be removed by inverting the base.
Then the fraction will be simplified according to the exponent (power)
All the steps are performed below:

$=\sqrt[5]{2^{-4} } \\=\sqrt[5]{1/2^4}\\ =\sqrt[5]{1/16}$

i hope it will help you!
