All the initial values [ 1000, -150, +150, etc ] are amounts, that can be positive or negative, so all are valid.
The functions (p/a, i, 8) have the form (function name, interest rate (=0.08), and number of periods), so all are valid.
Function names p/a, p/g,p/f are all valid.
What are not valid would be where two functions that are chained together that do not make sense.
For example, p/g and p/f both calculate the present values, and therefore cannot be chained together.  Similarly for p/a and p/f.  This makes options a and c invalid, respectively.

Pepsi [2]
G(x)=-5x-1
Change g(x) to y.
y=-5x-1
Switch x and y.
x=-5y-1
Solve for y.
x+1=-5y
Divide by -5.
(x+1)/-5=y

(x+1)/-5=y is your answer.

The pentagonal area is 20 cm square. Point A located in the pentagon and equidistant from all sides of the pentagon about 5 cm.
Maurinko [17]

Answer:

  about 8 cm

Step-by-step explanation:

The formula for the area of a regular polygon is ...

  A = 1/2Pa . . . . where P is the perimeter and "a" is the apothem, the distance from the center to a side

Filling in your numbers, we have ...

  20 cm^2 = (1/2)P(5 cm)

Dividing by the coefficient of P, we find ...

  2×(20 cm^2)/(5 cm) = P = 8 cm

The perimeter of the pentagon is about 8 cm.

_____

<em>Comment on the problem</em>

This calculation makes use of the area formula, as apparently intended. A regular pentagon with an apothem of about 5 cm will have an area of about 90.8 cm^2. The given geometry is impossible, as the pentagon is nearly 10 cm across. It cannot have a perimeter of only 8 cm.
