The circumference of the circle below is 20 cm. What is the length of AB (the minor arc)?

SOVA2 [1]

Answer: $AB=5.27\ cm$

Step-by-step explanation:

For this exercise it is important to remember that, by definition, the length of the minor arc can be calculated wih the following formula:

$arc\ length=(\frac{central\ angle}{360\°})(circumference)$

In this case , according to the data given in the exercise, you know that:

$arc\ length=AB\\\\central\ angle=95\°\\\\circumference=20\ cm$

Therefore, susbtituting those values into the formula, you get that length of AB is the following:

$AB=(\frac{95\°}{360\°})(20\ cm)\\\\AB=(\frac{191}{72})(20\ cm)\\\\AB=5.27\ cm$

$total \: increase \: for \:sides \: of \: the \: equillateral \: triangle = 3 \times 5cm = 15cm \\ perimeter \: of \: an \: equillateral \: triangle = 3 \times length \: of \: one \: side \\ originl \: perimeter = incresed \: perimeter - increase = 60cm - 15cm = 45cm \\ one \: side \: of \: the \: equillateral \: triangle = 45cm \div 3 = 15cm$

$let \: x \: represent \: the \: amount \: each \: person \: has \: in \: the \: end. \\ 40 - 4(7.50) = 4x \\ 40 - 30 = 4x \\ 10 = 4x \\ 4x = 10 \\ x = 10 \div 4 \\ x = 2.5 \\ each \: boy \: has \: 2.50 \: in \: the \: end$

Here is a table of values y = f(x)

Rama09 [41]

A. Yes, the value of this function is 8 when x is 15.

B. False. I noted right away that the ordered pair (0,5) is not included, and some of the ordered pairs included do not represent the given function.

C. Yes, f(5) = 6. See (A) above.

D. False. The range of this function is the set of integers between 5 and 13 inclusive.
