Answer:
(1) is a function, surjective aka onto,
not bijective aka one to one.
domain is {3,6,12,14,20,22},
range is {4,15,8,11}. More elements in domain means it can't possibly be one to one.
(2) is a relation but not a function, although its inverse is a function. There are fewer elements in the domain than the range, so a function could not be onto but would have to be into or injective.
The relation you get by restricting the domain to {1,19} is a function, injective, so that the image of the domain is a proper subset of the range.
Answer:
9.42477796 ≈ 9.4
Step-by-step explanation:
Ao= π*r
= π*(6/2)
=π*3= 9.42477796 ≈ 9.4
<span>There are many improper fraction equal to eight, they include: 8/1, 16/2, 24/3, 32/4, 40/5, 48/6, 56/7, 64/8, 72/9 etc.When a multiple of eight is divided by the other factor with with when multiplied to eight gives the multiple, the result will be eight.</span>
.75 because .75 is .25 from 1.0 and .25 from .5
