I am prerty sure it is 1/3 because 5 is 1/3 of 15 and 15 is 1/3 of 45
Hello :
cot(x) = cos(x)/sin(x) .... cot²(x) = cos²(x)/sin²(x)
1-sin²(x) = cos²(x)
cot²(x)(1-sin²(x)) = ( cos²(x)/sin²(x))× cos²(x) = 1/sin²(x)
To find (fg)(x), you must mult. together the two binomial functions f and g:
(fg)(x) = (6-5x)(6x^2+x = 36x^2 + 6x - 30x^3 - 5x^2
and then you must combine like terms: (fg)(x) = -30x^3 + 31x^2 + 6x

Answer:
x = 5
Step-by-step explanation:
x² - 5x = 0
(x² - 5x) /x = 0/x
x²/x - 5x/x = 0
x - 5 = 0
x = 5
Check:
x² - 5x = 0
5² - 5*5 = 0
25 - 25 = 0
