Assoli18 [71]

Answer:

The answer is option C=150%

Step-by-step explanation:

Original cost of the jacket=$16 in January

Final cost of jacket=$24 in September

What percentage must of the original price is the new?

The new price=the original price×(A percentage)

Where the new price=$24, the original price=$16, and the percentage=(x/100)

24=16×x/100

x=(24×100)/16=150%

The answer is 150%

Find all exact solutions that exist on the interval [0, 2π).<br> 1 − 2 tan(ω) = tan2(ω)<br><br> w =

Fofino [41]

A possible solution: First add 1 to both sides and reduce the RHS via the Pytagorean identity.

$1-2\tan\omega=\tan^2\omega\implies2-2\tan\omega=1+\tan^2\omega=\sec^2\omega$

Rewrite $\tan$ and $\sec$ in terms of $\sin$ and $\cos$ :

$\implies2\left(1-\dfrac{\sin\omega}{\cos\omega}\right)=\dfrac1{\cos^2\omega}$

Multiply both sides by $\cos^2\theta$ :

$\implies2(\cos^2\omega-\sin\omega\cos\omega)=1$

$\implies2\cos^2\omega-1=2\sin\omega\cos\omega$

Use the double angle identities:

$\implies\cos2\omega=\sin2\omega$

Divide both sides by $\cos2\omega$ :

$\implies1=\dfrac{\sin2\omega}{\cos2\omega}=\tan2\omega$

Now, $\tan2\omega=1$ for $2\omega=\dfrac\pi4+n\pi$ , or $\omega=\dfrac\pi8+\dfrac{n\pi}2$ , where $n$ is any integer. $\omega$ will fall in the interval $[0,2\pi)$ for $n=1,2,3,4$ , which means we have

$\omega=\dfrac\pi8,\dfrac{5\pi}8,\dfrac{9\pi}8,\dfrac{13\pi}8$
