Answer:

c = 6

Step-by-step explanation:

To solve we must isolate c:

10 = -2c + 22, turns into -12 = -2c because we must move the 22 over to the left side, and since it is positive, we must do the opposite operation
-12 = -2c, then turns into 6 = c, because we need to get the c by itself. To do so we divide both sides by -2, and when two negative numbers are divided together, the resulting number is positive

I hope this helps!

Find a function ω(x) such that the function f(x) = sin(ω(x)) has the roots at π, π2

atroni [7]

So, I came up with something like this. I didn't find the final equation algebraically, but simply "figured it out". And I'm not sure how much "correct" this solution is, but it seems to work.

$f(x)=\sin(\omega(x))\\\\f(\pi^n)=\sin(\omega(\pi^n))=0, n\in\mathbb{N}\\\\\\\sin x=0 \implies x=k\pi,k\in\mathbb{Z}\\\Downarrow\\\omega(\pi^n)=k\pi\\\\\boxed{\omega(x)=k\sqrt[\log_{\pi} x]{x},k\in\mathbb{Z}}$
