What are the domain restrictions of ?

1 answer:

5 0

The denominator : q² - 3q - 4 should be ≠ 0.
Let's find the zero values of this quadratic equation:

q' = [-b+√(b²-4.a.c)]/2.a and q'' = [-b-√(b<span>²-4.a.c)]/2.a

you will fond q' = 4 and q'' = -1

Then the restrictions are :

q </span>≠ 4 and q ≠ - 1 (1st answer)

If cos θ = .62 and if 0<θ<90 what is the approximate value of sin θ to the nearest hundredth

Deffense [45]

$\cos\Theta=0.62\\\\\text{Use:}\ \sin^2\alpha+\cos^2\alpha=1\\\\\sin^2\Theta+(0.62)^2=1\\\\\sin^2\Theta+0.3844=1\ \ \ |-0.3844\\\\\sin^2\Theta=0.6156\to\sin\Theta=\pm\sqrt{0.6156}\\\\\sin\Theta_1\approx-0.78\ \vee\ \sin\Theta\approx0.78\\\\\Theta\in(0^o;\ 90^o),\ therefore\ \sin\Theta \ \textgreater \ 0\to\boxed{\sin\Theta\approx0.78}$
