Which of the relations has a domain of {-5, 0, 5}? {(-5, 0), (0, 5), (1, 0)} {(-5, 5), (0, 5), (5,5)} {(0, -5), (0, 0), (0, 5)}?

The relation which has a domain of {-5, 0, 5} is:

               {(-5, 5), (0, 5), (5,5)}

Domain--

A domain is the set of all the possible x-values i.e. it is the first element of a ordered pair i.e. (x,y)

Range--

It is the set of all the y-values i.e. it is the second element in the set of the ordered pair i.e. (x,y)

a)

{(-5, 0), (0, 5), (1, 0)}

The domain of this relation is: {-5,0,1}

Range is: {0,5}

b)

{(-5, 5), (0, 5), (5,5)}

The domain of this relation is: {-5,0,5}

Range is: {5}

c)

{(0, -5), (0, 0), (0, 5)}

The domain of this relation is: {0}

Range is: {-5,0,5}

i got 86 for this

hope this !

if you need an explanation just ask

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
