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

The slope-intercept form of the equation of a line that passes through point (–3, 8) is y = –2/3x + 6. What is the point-slope f
Lubov Fominskaja [6]
I think the correct answer would be the last option. The correct point slope form would be <span>y – 8 = –2/3(x + 3). To write  this, we only follow the general formula y - y1 = m(x -x1) where m is the slope which is -2/3 and x1 and y1 is the point given above. We do as follows:</span>

y - y1 = m(x-x1)
y -  8 = -2/3 (x + 3)

If f(x)=-4x^2-6x-1 and g(x)=-x^2-5x+3, find (f+g)(x)
Nookie1986 [14]

Answer:

f(x)=-4x^2-6x-1

g(x)=-x^2-5x+3

(f+g)(x) = (-4x^2-6x-1) + (-x^2-5x+3)

-4x^2 - 6x - 1 -x^2 - 5x + 3

= -5x^2 - 11x + 2

The equation x^2-9y^2=900 <span>defines a hyperbolic cylinder.
</span>
1. Divide the equation x^2-9y^2=900  by 900:
\dfrac{x^2}{900} - \dfrac{y^2}{100} =1.
This is the equation of conic section when z=0 (or z=const) and that is hyperbola equation.

2. To find the domain and the range you should express y:
\dfrac{y^2}{100} =\dfrac{x^2}{900} - 1 \\   \\ y^2= \dfrac{x^2}{9} -100 \\   \\ y=\pm  \sqrt{\dfrac{x^2}{9} -100}.
Since you have square root, 
\dfrac{x^2}{9} -100\ge 0 \\ x^2-900\ge 0 \\ (x-30)(x+30)\ge 0 \\ x\in(-\infty,-30)\cup (30,\infty). This is the domain, the range is y\in (-\infty,\infty).
