Answer:

The answer is that the turning point, or vertex is: (4, 19)

Step-by-step explanation:

Given:

x^2 + 8x + 3

Separate out the first two terms with parenthesis:

(x^2 + 8x) + 3

Add 16 to complete the square, in the parenthesis and to the constant:

(x^2 + 8x + 16) + 3 + 16

Reduce:

(x + 4)^2 + 19

This is in the form:

(x + p)^2 + q

The vertex is at: (4, 19)

Abigail has a cylindrical candle mold with the dimensions shown. If Abigail has a rectangular block of wax measuring 15 cm by 12

luda_lava [24]

Find the volume of the candle using the formula for volume of a cylinder:

V = PI x r^2 x h = 3.14 x 3.4^2 x 6 = 217.79 cubic cm. Round to 217.8

Find the volume of the block: V = l x w x h = 15 x 12 x 18 = 3,240 cubic cm.

Now divide the volume of the block by the volume of a candle:

3240 / 217.8 = 14.88

Round to the nearest tenth = 14.9 candles.
