\begin{gathered} \text{ On the interval (}\frac{\pi}{6},\frac{\pi}{3})\text{ ,} \\ \cos (3\theta)\in\lbrack0,-1\rbrack \end{gathered}

Therefore,

r=6\cos (3\theta)\text{ is in \lbrack{}0,-6\rbrack on the interval (}\frac{\pi}{6},\frac{\pi}{3})

Write the equation of a polynomial of degree 3, with zeros 1, 2 and -1 where f(0)=2
ser-zykov [4K]

Answer:

f(x) = x^3 - 2x^2 - x + 2

Step-by-step explanation:

since the zeroes are 1,-1, and 2. we can write the function like

f(x) = (x-1)(x+1)(x-2)

f(x) = (x^2-1)(x-2)

f(x) = x^3 -2x^2 -x +2

and it is true that f(0)=2

The sum of 69 and 42 is five more than the difference of 146 and a number. Calculate the value of the unknown number.
Len [333]
As an equation, we have:
69+42=5+(146-x)

You just have to simplify:

111=5+(146-x)
106=146-x
-40=-x
40=x

Your unknown number is 40
