(Q2) Determine the eccentricity, the type of conic, and the directrix for r = 9/1+cos theta
g100num [7]

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

Christopher’s backyard is shaped like a rectangle with a length of 2x + 5 feet and a width of 4x - 7 feet.
Doss [256]

Answer:

8x² + 6x - 35

Step-by-step explanation:

A = (2x + 5)(4x - 7)

Front: 2x * 4x = <em>8x²</em>

Outside: 2x * (-7) = <em>-14x</em>

Inside: 5 * 4x = <em>20x</em>

Last: 5 * -7 = <em>-35</em>

Add up: <em>8x² - 14x + 20x -35</em>

Simplify: 8x² + 6x - 35
