If ya meant pi as in π



π is defined as the ratio between the circumference and diameter of any circle

the definition of pi is \pi=\frac{circumference}{diameter}

I'm sure you mean π (pronounce as "pie" and spelled as "Pi"), the sixteenth letter of the Greek alphabet. π is the ratio between a circle's circumference and it's diameter.

Molly had a $12 gift card to download music. She bought 8 songs that each cost the same amount. Write a variable equation, then
Ghella [55]

Answer:

Molly paid for each song $1.5

Step-by-step explanation:

Let

x ------> amount that Molly paid for each song

we know that

The amount that Molly paid for each song multiplied by 8 is equal to the gift card value

so

The linear equation that represent this problem is

8x=12

Solve for x

Divide by 8 both sides

x=12/8

x=\$1.5

Molly paid for each song $1.5

Using the bijection rule to count binary strings with even parity.
AleksandrR [38]

Answer:

Lets denote c the concatenation of strings. For a binary string <em>a</em> in B9, we define the element f(a) in E10 this way:

  • f(a) = a c {1} if a has an odd number of 1's
  • f(a) = a c {0} if a has an even number of 1's

Step-by-step explanation:

To show that the function f defined above is a bijective function, we need to prove that f is well defined, injective and surjective.

f   is well defined:

To see this, we need to show that f sends elements fromo b9 to elements of E10. first note that f(a) has 1 more binary integer than a, thus, it has 10. if a has an even number of 1's, then f(a) also has an even number because a 0 was added. On the other hand, if a has an odd number of 1's, then f(a) has one more 1, as a consecuence it will have an even number of 1's. This shows that, independently of the case, f(a) is an element of E10. Thus, f is well defined.

f is injective (or one on one):

If a and b are 2 different binary strings, then f(a) and f(b) will also be different because the first 9 elements of f(a) form a and the first elements of f(b) form b, thus f(a) is different from f(b). This proves that f in injective.

f is surjective:

Let y be an element of E10, Let x be the first 9 elements of y, then f(x) = y:

  • If x has an even number of 1's, then the last digit of y has to be 0, and f(x) = x c {0} = y
  • If x has an odd number of 1's, then the last digit of y has to be a 1, otherwise it wont be an element of E10, and f(x) = x c {1} = y

This shows that f is well defined from B9 to E10, injective, and surjective, thus it is a bijection.

Find the arc length of a 80° slice of a large 15 in. radius pizza.
Sedaia [141]

Answer:

  • 20.93 in

Step-by-step explanation:

<u>Arc length formula:</u>

  • s = 2 π r (θ/360°)

<u>Substitute values:</u>

  • s = 2*3.14*15(80/360) = 20.93 in
