Need help please assist me find the area of a regular hexagon

garri49 [273]

Answer:

The area of the regular hexagon is $166.3\ units^{2}$

Step-by-step explanation:

we know that

The area of a regular hexagon can be divided into 6 equilateral triangles

step 1

Find the area of one equilateral triangle

$A=\frac{1}{2}(b)(h)$

we have

$b=r=8\ units$

$h=4\sqrt{3}\ units$ ----> is the apothem

substitute

$A=\frac{1}{2}(8)(4\sqrt{3})$

$A=16\sqrt{3}\ units^{2}$

step 2

Find the area of 6 equilateral triangles

$A=(6)16\sqrt{3}=96\sqrt{3}=166.3\ units^{2}$

The rent for an apartment is represented by R(a) = 2.00a + 50.00, where a is the area of the apartment in square feet. The rent

QveST [7]

Answer:

<em>The correct option is: D) S(a) = 2.00a + 100.00; shift 50 units up</em>

Step-by-step explanation:

The rent for an apartment is represented by $R(a) = 2.00a + 50.00$

Now, the rent increases by $50.00 when the apartment is furnished. So, the rent of a furnished apartment will be: $(2.00a+50.00+50.00) = (2.00a+100.00) dollar$

Thus the new function will be: $S(a)= 2.00a+100.00$

<u>As the output of the original function is increased by 50.00, so the graph of the original function will shift 50 units upward</u>.
