Please help it’s easy! In a relation, the input is the number of people and the output is the number
of umbrellas.
Is this relation a function? Why or why not?
O A. No, because the same number of people might have a different
number of umbrellas.
B. Yes, because a given number of people always has the same
number of umbrellas.
C. Yes, because each person has one umbrella.
D. No, because you do not know how many people there are.

A

Step-by-step explanation:

The amount of umbrellas a person has is not given nor is it listed as a constant, meaning that this cannot be a function.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
