Draw the diameter from point (-1, -5) to point (2, 3).

The triangle has base 3 and height 8.

The diameter of the semicircle is the hypotenuse of the triangle.

d = \sqrt{3^2 + 8^2}

d \approx 8.544

The radius is half the diameter.

r = \dfrac{d}{2} = \dfrac{8.544}{2} = 4.272

The total area is the area of the triangle plus the area of the semicircle.

A = \dfrac{bh}{2} + \dfrac{\pi r^2}{2}

A = \dfrac{3 \times 8}{2} + \dfrac{\pi \times 4.272^2}{2}

A = 12 + 9.125 \pi units^2

HELP ME PLZ ASAPPPPPP

Answer:

(x,y) =(-4,-3) --- Vertex

x = -4 --- Axis of symmetry

Step-by-step explanation:

Given

y = -6(x + 4)^2 - 3

Solving (a): The vertex

For an equation written in

y = a(x - h)^2 + k

The vertex is:

(x,y) = (h,k)

By comparison:

y = a(x - h)^2 + k  and y = -6(x + 4)^2 - 3

-h =4       k = -3

h =-4         k = -3  

So, the vertex is:

(x,y) =(-4,-3)

Solving (b): The axis of symmetry

For an equation written in

y = a(x - h)^2 + k

The axis of symmetry is:

x = h

In (a):

h =-4

So:

x = -4
