Answer:
Step-by-step explanation:
The zeros of the polynomial are all the values of x for which the function
In this case we know that the zeros are:
,
Now we can write the polynomial as a product of its factors
Note that the polynomial is of degree 3 because the greatest exponent of the variable x that results from multiplying the factors of f (x) is 3
Answer:
cosA = 0.6
Step-by-step explanation:
Using the Pythagorean identity
sin²A + cos²A = 1 ( subtract sin²A from both sides )
cos²A = 1 - sin²A ( take the square root of both sides )
cosA = ±
Since only the positive value is required , then
cosA =
=
=
= 0.6
