navik [9.2K]

Answer:

The variable c represents the domain as it is the independent variable.

The domain of the function F(c) is given by c ≥ 0.

So, only positive values for the input make sense.

The upper limit of the domain is +∞ and lower limit is 0.

It is not possible for the team to earn $50.50 as it will be only multiple of 2.

Step-by-step explanation:

If F(c) represents the earning of a volleyball team from selling c cupcakes and each cupcake costs $2 each, then the equation that models the situation is  

F(c) = 2c ..... (1)

The variable c represents the domain as it is the independent variable. (Answer)

Which statement regarding the interior and exterior angles of a triangle is true?
yulyashka [42]
Draw a triangle on your paper and extend the base of the triangle so it extends past the base angle.  The base angle inside the triangle is the interior angle and the one outside the triangle between the extended line and the outside of the interior angle is the exterior angle.  A straight line has a measure of 180 degrees.  That means that the interior angle + the exterior angle = 180.  So they are supplementary by definition of supplementary angles.  A is the only choice above that applies.
