Answer:

Distance from Anchorage (longitude 150 degrees W) to Saint Petersburg (longitude 30 degrees E) = 10,002.47 KM

Step-by-step explanation:

As earth is a sphere of radius 6371 km.

Therefore at 60 degree latitude, the radius of circle can be calculated as shown below:

= 6371 * Cos 60

= 3185.5 KM

Saint Petersburg is nearly 180 degree about Anchorage by flying directly east.

So Distance from Anchorage (longitude 150 degrees W) to Saint Petersburg (longitude 30 degrees E) can be calculated as shown below:

= (180 * 2 * 3.1416 * 3185.5) / 360

= 10,002.47 KM

Given the graph of a degree 3 polynomial below, complete the table of values for either the x-value of a zero, or the multiplici
leva [86]

The roots or zeros of a polynomial are the points it crosses the x-axis.

The roots of the polynomial in order from least to greatest are -5, 0 and 5

From the graph (see attachment), we have the following highlights

  • <em>The graph cross the x-axis at x = -5</em>
  • <em>The graph cross the x-axis at x = 0</em>
  • <em>The graph cross the x-axis at x = 5</em>

The points at which the graph crosses the x-axis are the roots of the graph.

So, the roots are: -5, 5 and 5
