Answer:
is the required polynomial function of the form 
Step-by-step explanation:
The given zeroes of the polynomial is -5 and 4i.
It implies, the roots of the polynomial is (x+5) and (x-4i)
Now, The Polynomial = Product of all its roots
So, here P(x) = ( x + 5)( x - 4i)
or, 
⇒
Hence, P(x) is the required polynomial function of the form
Answer:
ab² - 9
Step-by-step explanation:
Given in the question an expression
(ab + 3)(ab - 3)
To product mentally we will use polynomial identity called
Difference of squares
<h3>a² - b² = (a+b)(a-b) </h3>
here a = ab
b = 3
(ab + 3)(ab - 3) = ab² - 3² = ab² - 9
Answer:
B
This is a 30-60-90 Triangle which means that the long side is twice the short side and the hypotenuse is Square Root 3 times bigger
Ok, C is 16 feet below the sea level = -16
D is below the sea level is 1/2 of the elevation of city it's mean
-16 divided 1/2 = -8
Solve: -8 multiply 2 is -16
