Natali [406]

Answer:

D

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

here (h, k) = (- 3, - 6), thus

y = a(x + 3)² - 6

To find a substitute (0, 0) into the equation

0 = 9a - 6 ⇒ a = \frac{6}{9} = \frac{2}{3}

y = \frac{2}{3}(x + 3)² - 6 ← in vertex form

Expand (x + 3)² and distribute by \frac{2}{3}

y = \frac{2}{3}(x² + 6x + 9) - 6

  = \frac{2}{3} x² + 4x + 6 - 6

  = \frac{2}{3} x² + 4x  ← in standard form

How are a ruler, a yardstick, and a measuring tape the same? How are they different?
QveST [7]
They all use the metric unit to measure things (e.g. inches, centimeters, etc.)  
As far as I know, I think the difference might be that a yardstick only measures 1 yard. It has 36 inches (which is 3 feet, which is also 1 yard).
A ruler usually is only 12 inches. 
A measuring tape is usually 12 feet.
That's what I know.
