If you're trying to solve for x, you need to use the quadratic formula.
Plug in the numbers from the standard form of a quadratic equation
(which is
)
From here, this solves down to
Take the square root of 196, which is 14
Now, you can solve for both the + and - variations on the equation.
The solutions to your equation are 1.5 and 5/8 (probably)
<span>If you are given a 6-meter pole that is supported by guy wires that are anchored to the ground, you can create a relationship with respect to sin theta. sin theta is equal to the 6 meters over the slant line supported by the pole. as shown. </span>
Answer:
They are correct. :)
Step-by-step explanation:
Answer:
The answer is (d) ⇒ eccentricity = 6 , hyperbola , directrix x = 3/2
Step-by-step explanation:
∵ r = ek/(1 ± ecosФ)
∵ r = 9/(1 + 6cosФ)
∴ e = 6 ⇒ eccentricity = 6
∵ e > 1
∴ The conic is hyperbola
∵ ek = 9
∴ k = 9/6 = 3/2
∴ The directrix x = 3/2
