Find the values of the trigonometric functions of θ from the information given.
OLga [1]

Answer:

  • sin(θ) = -(4√15)/17
  • cos(θ) = 7/17 . . . . . . . given
  • tan(θ) = -(4√15)/7
  • csc(θ) = -(17√15)/60
  • sec(θ) = 17/7
  • cot(θ) = -(7√15)/60

Step-by-step explanation:

The relationship between sine and cosine is ...

  sin² + cos² = 1

Solving for sine gives ...

  sin = ±√(1 -cos²)

In this problem, we want the negative root.

  sin(θ) = -√(1 -(7/17)²) = -√(240/289) = -(4√15)/17

  tan(θ) = sin(θ)/cos(θ) = ((-4√15)/17)/(7/17) = -(4√15)/7

___

And the inverse functions are ...

  sec(θ) = 1/cos(θ) = 17/7

  csc(θ) = 1/sin(θ) = -17/(4√15) = -(17√15)/60

  cot(θ) = 1/tan(θ) = -(7√15)/60

_____

Of course, you're aware that 1/√15 = (√15)/15.

Because the initial value is $26.40, the line must pass through this when x is 0. Thus, the answer is either the first or the second equation.
Next, we calculate the difference between the year 2019 and 1998 and substitute it into the value of x.
2019 - 1998 = 21.
Substituting this into the equation:
y = 1.006(21) + 26.40
y = $47.52

Thus, the first option is correct.
