Find the area of a regular decagon with perimeter 100 units. Show all work.
Slav-nsk [51]
A regular polygon has ten (10) equal sides ( since it is regular).
We are given with the perimeter value which is 100 units and the perimeter formula is P = 10a
Solving for a (the side measurement), we have:
100 = 10a
a= 100/10
a =10

We can now proceed in solving the area and the formula is shown below:
Area = 5/2 a√ (5+2√5)
Area = 5/2 * 10√(5+2√5)
Area = 76.94 square units

The answer is 96.94 square units.

Arithmetic of Functions problem<br> Open ended
VladimirAG [237]

Answer: <em>(gºh)(25)=2</em>


Step-by-step explanation:

1. This exercise is about Composition of functions, then you have:

2. Then, you have that

<em>(gºh)(25)</em>=g(h(x))=\sqrt{x}-3

3. Now, you must substitute 25 into the function, as you can see below:

<em>(gºh)(25)</em>=\sqrt{25}-3

4. Simplify the fucntion.

5. Therfore, you obtain:

<em>(gºh)(25)</em>=5-3=2

Of the following, which is the solution to 2x2 + 3x = −5? (6 points) Select one: a. the quantity negative three plus or minus i
jeka94

"2x2 + 3x = −5" should be re-written as 2x^2 + 3x +5 = 0. This is a quadratic equation with a=2, b=3 and c=5. Thus, the roots are:

-3 plus or minus √(9-4[2][5])

x = ---------------------------------------------

4

or:

-3 plus or minus √(-31)

x = ----------------------------------

4

or:

-3 plus or minus i*√31

x = ----------------------------------
