For the answer to the question above, this is a right triangle problem using the tangent function.
Tan(x) = Opposite (O) / Adjacent (A) 
x = 40 degrees 
A = 30 ft 
Solve for O 
O= Tan (x) * A 
O = Tan (40) * 30 
Use your calculator or whatever method to get the tangent of 40 degrees (which is .84) 
O = .84 * 30 
O = 25.2 Ft

Let the cost of gasoline in the year 2000 be represented b the equation
y = a + b*x
where
x = months, counted from January
y = cost, dollars

The given data in the table is
Month: Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
x, months: 1 2 3 4 5 6 7 8 9 10 11 12
y, dollars: --- --- --- --- 1.76 2.13 --- --- --- --- --- ---

When x = 5, y = 1.76.
Therefore
a + 5b = 1.76 (1)

When x = 6, y = 2.13
Therefore
a + 6b = 2.13 (2)

Subtract equation (1) from (2).
a + 6b - (a + 5b) = 2.13 - 1.76
b = 0.37

From (1), obtain
a = 1.76 - 5b
= 1.76 - 5*0.37
= -0.09

The required equation is
y = 0.37x - 0.09
The graph shows the line, with the given data for May and June.

Answer: D. y = 0.37x - 0.09
