What is the domain and range?
MrRissso [65]

Hello from MrBillDoesMath!

Answer:

Domain = { 5. 10. 15. 20}

Range =  -3,-1,1,3} .


Discussion:

The domain is the set of all "x" values, that is  { 5. 10. 15. 20} and the range is (-3,-1,1,3} . The arrows in the diagram show the mapping between the domain and the range. For examples, 5 -> 1 ( "x value 5 is mapped to y value 1"),        10 ->3, 15 ->-3, and 20 -> -2


Thank you,

MrB

The circumference of circle x in which a = 49pi in squared
zzz [600]

Answer:

C = 14 pi inches

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

49 pi  = pi r^2

Divide each side by pi

49 pi/pi = pi /pi r^2

49 = r^2

Take the square root of each side

7 = r

The circumference is given by

C = 2 * pi *r

C = 2 * pi *7

C = 14 pi inches
