Answer:

The answer to your question is x = 3; y = 3

Step-by-step explanation:

Data

angle = 45°

Opposite side = x

Adjacent side = y

hypotenuse = 3√2

To solve this problem, use trigonometric functions.

1) To find x, use the trigonometric function sine.

              sin Ф = Opposite side / hypotenuse

-Solve for Opposite side (x)

              Opposite side = hypotenuse x sin Ф

-Substitution

              Opposite side = 3√2 sin 45

-Simplification

               Opposite side = 3√2 (1 / √2)

               Opposite side = 3(1)

-Result  

               x = 3

2) To find y use the trigonometric function cosine

               cos Ф = Adjacent side / hypotenuse

-Solve for Adjacent side

                Adjacent side = hypotenuse x cos Ф

-Substitution

                Adjacent side = 3√2 x cos 45

-Simplification

                Adjacent side = 3√2 x (1/√2)

                Adjacent side = 3(1)

-Result

                y = 3

Value discounting refers to the fact that the percieved value of the reinforcer is less the longer you have to wait for it. See

Answer:

there is an economic principle that states that 1 dollar today is worth more than 1 dollar in the future, since an invested dollar could earn interests and gain value.

For example, we can assume a 6% interest rate (0.5% monthly interest rate), and using the present value formula we can determine the present value of $100:

  • given to us in 30 days = $100 / (1 + 0.5%)¹ = $99.50
  • given to us in 150 days = $100 / (1 + 0.5%)⁵ = $97.54
  • given to us in 300 days = $100 / (1 + 0.5%)¹⁰ = $95.13

In order to calculate the value of $100 given to us tomorrow, we would need to determine a daily interest rate = 6% / 360 = 0.00017

  • $100 given to us tomorrow = $100 / (1 + 0.00017)¹ = $99.98

since the amount of money is not that large and the interest rate is rather low, the difference in value is not that large. But imagine if you used a 24% interest rate instead of 6% (monthly interest rate = 2%)

  • $100 given to us in 30 days = $100 / (1 + 2%)¹ = $98.04
  • $100 given to us in 150 days = $100 / (1 + 2%)⁵ = $90.57
  • $100 given to us in 300 days = $100 / (1 + 2%)¹⁰ = $82.03

as the interest rate increases, the present value decreases.
