Answer:

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

Answer: choice C) -15x^4y

-----------------------------------------

Explanation:

The coefficients are -3 and 5. They are the numbers to the left of the variable terms
Multiply the coefficients to get -3*5 = -15. So -15 is the coefficient in the answer

Multiply the x terms to get x^3 times x = x^(3+1) = x^4. Notice the exponents are being added

Do the same for the y terms as well: y^2 times y^(-1) = y^(2+(-1)) = y^(2-1) = y^1 = y

So we have a final coefficient of -15, the x terms simplify to x^4 and the y terms simplify to just y

Put this all together and we end up with -15x^4y which is what choice C is showing

How many different ways can 3 singers be selected from 5 who came to an audition
abruzzese [7]

This is known as "5 take 3", where ordering is not important.

\binom{5}{3} = \frac{5!}{3!(5-3)!} = \frac{120}{6\cdot2} = 10

Find the missing side lengths. Leave your answers as radicals in simplest form. Show your work to support your answer ​
kotegsom [21]

Answer

x=2 and y=2√2

Step-by-step explanation:

\sin( \alpha )  =  \frac{2 \sqrt{2} }{x }  \\ x =  \frac{2 \sqrt{2} }{ \sin(45) }  \\ x = 4 \\  {x}^{2}  =  {y}^{2}  + 2 \sqrt{2}  \\  {4}^{2}  =  {y}^{2}  + (2 \sqrt{2 \: )}^{2}  \\ 16 =  {y}^{2}  + 8 \\ 16 - 8 =  {y}^{2}  \\ y =  \sqrt{8}  \\ y = 2 \sqrt{2}

I need help with math the question is
velikii [3]

Answer:

P=2(S-lw)/h

Step-by-step explanation:

we have that

The formula for the surface area of the enclosed space is

S=lw+0.5Ph

Solve for P

That means ------> isolate the variable P

Subtract lw both sides

S-lw=lw+0.5Ph-lw

S-lw=0.5Ph

Multiply by 2 both sides

2(S-lw)=(2)0.5Ph

2(S-lw)=Ph

Divide by h both sides

2(S-lw)/h=Ph/h

2(S-lw)/h=P

Rewrite

P=2(S-lw)/h
