A student claims that -9i is the only imaginary root of a quadratic polynomial equation that has real coefficients.
a. What is the mistake in the student's claim? (2 points)
HINT: If there is another solution, what is it. If there is another solution, what
theorem is used to support your claim.
b. Write one possible factored polynomial that has the correct roots from part a by
filling in the missing parts to the polynomial below. (1 points)
C. Write the factored polynomial from part b in standard form. (1 points)

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

the answer is 3/2 and for decimal: 1.5

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.
