Answer:

  sin(θ) ≈ -0.92

  cos(θ) ≈ 0.38

  tan(θ) = -2.40

Step-by-step explanation:

Let r represent the distance of the point from the origin. The Pythagorean theorem tells us ...

  r² = (5)² + (-12)²

  r² = 169

  r = √169 = 13

The trig relations for a point on the terminal ray are ...

  (x, y) = (r·cos(θ), r·sin(θ))

Then ...

  sin(θ) = y/r = -12/13 ≈ -0.92

  cos(θ) = x/r = 5/13 ≈ 0.38

  tan(θ) = y/x = -12/5 = -2.40

A collection of nickels and quarters is worth 2.85 . There are 3 more nickels than quarters how many nickels and quarters are th
Zolol [24]

A nickel is equal to 5 cents or 0.05 dollars.

A quarter is equal to 25 cents or 0.25 dollars.

Let number of nickels be = n

Let number of quarters be = q

0.05n+0.25q=2.85    ...........(1)

As it is given, there are 3 more nickels than quarters so equation becomes,

n=q+3   ................(2)

Plug in the value of 'n' from (2) in (1)

0.05(q+3)+0.25q=2.85

= 0.05q+0.15+0.25q=2.85

0.30q=2.70

q=9

As n=q+3 we get, n=9+3=12

Hence, there are 12 nickels and 9 quarters.
