The focus of a parabola is located at (0,–2). The directrix of the parabola is represented by y = 2. Which equation represents t

Archy [21]

Answer:

$\boxed{x^2=-8y}$

Step-by-step explanation:

$(a,b)\ is \ the\ focus\\y=k\ is \ the\ directrice\\\\Formula\ to\ use:\ y=\dfrac{(x-a)^2}{2(b-k)} +\dfrac{b+k}{2} \\\\Here: \ a=0,\ b=-2, \ k=2\\\\y=\dfrac{(x-0)^2}{2(-2-2)} +\dfrac{-2+2}{2} \\\\so\ y=-\dfrac{x^2}{8} \\\\or\ x^2=-8y$

Answer:Area of the lawn is 1725 ft^2

Step-by-step explanation:

The yard is in the shape of a trapezoid. The area of the lawn can be determined by finding the area of the trapezoid. The formula for determining the area of a trapezoid is expressed as

Area of trapezoid =

1/2(a + b)h

Where

a is the length of one of the parallel sides of the trapezoid

b is the length of the other parallel side of the trapezoid.

h is the perpendicular height of the the trapezoid.

From the diagram,

a = 50 feet

b = 65 feet

h = 30 feet

Area of the lawn = 1/2(50 + 65)× 30

= 1/2 × 115 × 30 = 1725 ft^2
