12598 rounded to the nearest thousands is 1260
The answer would be mercury.
Step-by-step explanation:
sec x − cos x
Secant is the inverse of cosine:
(1 / cos x) − cos x
Find the common denominator:
(1 / cos x) − (cos² x / cos x)
Subtract:
(1 − cos² x) / cos x
Answer:
-
or -
+8x-16
Step-by-step explanation:
Given a second degree polynomial has a root 4 with multiplicity 2
That means, 4 is a repeating root of the polynomial.
Any second degree polynomial has at most 2 real roots.
⇒Both roots of the polynomial are 4.
and its expression can be written as c·
where c is a real number
⇒c·(
-8x+16)
⇒c
-8cx+16c
Also, the leading coefficient is given as -1
So, c = -1
and the expression becomes (-1)
-8·(-1)·x+16·(-1)
⇒<u>-
+8x-16</u>
