What is the leading coefficient of a cubic polynomial that has a value of −208 when x=1, and has zeros of 5, 5i, and −5i?

2

Step-by-step explanation:

We already have the zeros, so we can write the cubic polynomial in this general form:

Where:

So we have that:

To find the value of the leading coefficient 'a', we can use the point (1, -208) given:

So the leading coefficient is 2.

if u add 1/3 every 15 minutes after an hour u will have 4/3 or 1 1/3

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
