The area of the regular pentagon is 6.9 cm2. What is the perimeter? 2 cm 5 cm 10 cm 20 cm
disa [49]

Given

Area of the regular pentagon is 6.9 cm².

Find out the perimeter of a regular pentagon

To proof

Formula

Area of regular pentagon is

= \frac{1}{4}\sqrt{5(5+2\sqrt{5})}\ a^{2}

As given in the question

area of regular pentagon = 6.9 cm²

now equating the area value with the area formula.

6.9 =\frac{1}{4}\sqrt{5(5+2\sqrt{5})} a^{2}

Now put

√5 = 2.24 ( approx)

put in the above equation

\frac{6.9\times 4}{\sqrt{5(5+2\times2.24)}}=a^{2}\\\frac{27.6}{\sqrt{47.4}}=a^{2}\\\frac{27.6}{6.88}=a^{2}

thus

a² = 4.01

a = √ 4.01

a = 2.0 cm ( approx)

As perimeter  represented the sum of all sides.

i.e regular pentagon have five sides of equal length.

Thus

perimeter of the regular pentagon = 5 × side length

                                                         = 5 ×2.00

therefore the perimeter of the regular pentagon = 10cm

option c is correct

Hence proved

If f(x)=x^4+3x^3-x^2+6, find f(-3).
docker41 [41]

Answer:

f(-3) = -3

Step-by-step explanation:

Step 1: f(x) means "f of x" and f(-3) means "f of -3", so you have to replace all the "x" letters in the function with the value -3.

f(x)=x^4+3x^3-x^2+6\\f(-3)=(-3)^4+3(-3)^3-(-3)^2+6

Step 2: Apply the exponents. <em>Make sure you remember to put in the -3 and not just 3.</em>

f(-3)=81+3(-27)-9+6

Step 3: Use BEDMAS rules to complete the calculation.

f(-3)=81-81-9+6

f(-3)=-3

Therefore the answer is f(-3) = -3.

Help asap i need help
gulaghasi [49]

Answer:

1st option: G, H, I

Step-by-step explanation:

Collinear points are points that lie on the same straight line.

In the diagram, the collinear points are:

• L, H, J

• G, H, I, K

For the 2nd option, I does not lie on the same straight line as L and H.

For the 3rd option, J does not lie on the same straight line as G and H.

For the 4th option, J does not lie on the same straight line as G and I.

Thus, the 2nd, 3rd and 4th options are incorrect.
