What conic section degenerates into a line?
andrew11 [14]
<h3>Answer: A) parabola</h3>

Some degenerate parabola cases form a single straight line, while other cases form one pair of parallel lines.

A degenerate hyperbola forms two lines that intersect at the vertex of the cone. We can rule out choice B.

A degenerate circle is a single point, so we can rule out choice C.

A degenerate ellipse is also a single point. Any circle is an ellipse (but not the other way around). We can rule out choice D.

The hypotenuse of a right triangle is 9 inches long and another side is 6 inches. Find the length of the missing side. Round you
olga nikolaevna [1]
A² + b² = c²
a² = c² - b²
a² = 9² - 6²
a² = 81 - 36
a² = 45
a = √45
a ≈ 6.7082
a = 6.7

The point P(9, 12) is on the terminal side of θ. Evaluate cos θ.
frutty [35]
<span>P(9,12): For all intents and purposes, the hypotenuse is "r", the opposite side is "y", and the adjacent side is "x".

x = 9 (from the P(9,12))
y = 12 (also from the point)

Using the Pythagorean Theorem, you find out that r = 15.

Therefore, since cos θ = x/r
cos θ = 9/15 or 3/5

Answer: 3/5</span>
