Answer: B.
Using trigonometric ratios, we know that:
tan x = opp/adj
Plug in the values.
tan A = 20/48
The side opposite to angle A is 20, and the adjacent side is 48.
Simplify the fraction.
tan A = 5/12
8 + 0 = 8: identity- addition (any number + 0= that number)
<span>a(b + c) = ab + ac: distributive (multiplying a on the left-hand side of the equation by the numbers in parenthesis gives you the right-hand side of the equation) </span>
<span>b + a = a + b: commutative- addition (numbers can be added in any order and still produce the same answer) </span>
<span>If 2 = x, then x = 2: symmetric (if a = b then b = a) </span>
<span>x(10) to be written 10x: commutative- multiplication (numbers can be multiplied in any order and still produce the same result)</span>
Answer:
Step-by-step explanation:
A standard polynomial in factored form is given by:
Where <em>p</em> and <em>q</em> are the zeros.
We want to find a third-degree polynomial with zeros <em>x</em> = 2 and <em>x </em>= -8i and equals 320 when <em>x </em>= 4.
First, by the Complex Root Theorem, if <em>x</em> = -8i is a root, then <em>x </em>= 8i must also be a root.
Therefore, we acquire:
Simplify:
Expand the second and third factors:
Hence, our function is now:
It equals 320 when <em>x</em> = 4. Therefore:
Solve for <em>a</em>. Evaluate:
So:
Our third-degree polynomial equation is:
