Suppose that all of the points on the circular dartboard shown are equally likely to be hit by a dart. If the radius of the shad

ed center circle is 1 and the radius of the entire dartboard is 4, what is the probability of throwing a dart and hitting the white part of the board? Round your answer to the nearest whole number.

Answer: The probability of throwing a dart and hitting the white part of the board is 1.

Step-by-step explanation:

Since we have given that

Radius of shaded center circle = 1

So, Area of shaded center circle is given by

\pi r^2\\\\=\pi \times 1^2\\\\=\pi

Radius of entire dartboard = 4

Area of entire dartboard is given by

\pi\times 4^2\\\\=16\pi

Area of white part is given by

16\pi-\pi\\\\=15\pi

So, Probability of throwing a dart and hitting the white part of the board is given by

\dfrac{15\pi}{16\pi}\\\\\\=\dfrac{15}{16}=0.9375\approx 1

Hence, the probability of throwing a dart and hitting the white part of the board is 1.

What is a perfect square? Why is <img src="https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B%208x%20%2B16" id="TexFormula1" title="x^{2}

Answer:

It is a perfect square. Explanation below.

Explanation:

Perfect squares are of the form

(

a

+

b

)

2

=

a

2

+

2

a

b

+

b

2

. In polynomials of x, the a-term is always x.(

(

x

+

c

)

2

=

x

2

+

2

c

x

+

c

2

)

x

2

+

8

x

+

16

is the given trinomial. Notice that the first term and the constant are both perfect squares:

x

2

is the square of x and 16 is the square of 4.

So we find that the first and last terms correspond to our expansion. Now we must check if the middle term,

8

x

is of the form

2

c

x

.

The middle term is twice the constant times x, so it is

2

×

4

×

x

=

8

x

.

Okay, we found out that the trinomial is of the form

(

x

+

c

)

2

, where

x

=

x

and

c

=

4

.

Let us rewrite it as

x

2

+

8

x

+

16

=

(

x

+

4

)

2

. Now we can say it is a perfect square, as it is the square of

(

x

+

4

)

.
