Answer:

(1,-3)

Step-by-step explanation:

<u>Complete the squares</u>

<u />y^2+6y+8x+1=0\\\\y^2+6y=-8x-1\\\\y^2+6y+9=-8x-1+9\\\\(y+3)^2=-8x+8\\\\(y+3)^2=-8(x-1)

We now compare to the equation (y-k)^2=2p(x-h) where (h,k) is the vertex of the parabola. Hence, the vertex of the parabola is (1,-3).

Which is smaller: an angle showing a turn through 1/8 of a circle or an angle showing a turn through 1/3 of a circle? Explain yo
Zolol [24]

Answer:

An angle showing a turn through 1/8 of a circle is smaller

Step-by-step explanation:

we know that

A complete circle represent 360°

so

<em>An angle showing a turn through 1/8 of a circle is</em>

(360\°)*(\frac{1}{8})=45\°

<em>An angle showing a turn through 1/3 of a circle is</em>

(360\°)*(\frac{1}{3})=120\°

therefore

An angle showing a turn through 1/8 of a circle is smaller
