Answer:

Step-by-step explanation:

The formula for determining the the volume of a rectangular base pyramid is expressed as

Volume = 1/3 × base area × height

From the information given,

Length of base = 9 cm

Width of base = 4.6 cm

Area of base = 9 × 4.6 = 41.4 cm²

Volume of pyramid = 82.8cm³

Therefore

82.8 = 1/3 × 41.4 × height

82.8 = 13.8 × height

Dividing both sides of the equation by 13.8, it becomes

height = 82/13.8

Height = 5.94 8 cm

Which graph represents a quadratic function that has no real zeros?
xxTIMURxx [149]

Answer:

2nd graph (in the attached pics)

Step-by-step explanation:

Graphically, the <em>x-intercepts of the graph of a quadratic function are its zeroes. </em>

There can be

  • no zeroes (where graph doesn't cut the x-axis at all),
  • 1 zero (where graph touches the x-axis at one point only), and
  • 2 zeros (where the graph cuts the x-axis at 2 points)

Looking at the figures, the 2nd graph has no real zeroes, <em>because the graph doesn't cut the x-axis at all!</em>

<em />

So, the answer is the second graph.
