Answer:

6 ft

Step-by-step explanation:

The surface area of a cube is given by

SA = 6s^2

216 = 6s^2

Divide each side by 6

216/6 = 6s^2/6

36 = s^2

Take the square root of each side

sqrt(36) = sqrt(s^2)

6 =s

Each side is 6ft

The equation y=ax^2 describes a parabola. If the value of a is positive, which way does the parabola open?
Ivenika [448]
<h3>Answer:</h3>

A. Up

<h3>Step-by-step explanation:</h3>

Parabolas are graphs that make U-shapes and are formed from quadratic equations.

Vertical Parabolas

There are 2 different types of parabolas: vertical and horizontal.

  • Vertical parabolas have a vertical axis of symmetry. So, they open up or down.
  • Horizontal parabolas have a horizontal axis of symmetry. So, they open left or right.

If the x-value is squared, then the parabola is vertical. So, this graph must open up or down.

Positive A-Value

The a-value is the coefficient before the squared term. In a vertical parabola, the graph opens up if the a-value is positive. On the other hand, the graph opens down when the a-value is negative.

In this case, the graph is a vertical parabola that opens up. This means that the range will have a minimum value but no maximum.
