The worker gets paid $18.50 for the first 40 hours of work. The worker works 46 hours. 18.50 • 40 = 740. He worked 6 hours overtime. $18.50 ÷ 2 = $9.25. $9.25 • 6 = $55.50.

$740 + $55.50= $795.50

Double angle identity. Just 5 questions. Really need help as my teacher has been frustrated with me

BartSMP [9]

The double angle identities are

$\sin(2x)=2\sin x\cos x$

$\cos(2x)=\cos^2x-\sin^2x$

Then

$2\sin\dfrac\pi6\cos\dfrac\pi6=\sin\left(\dfrac{2\pi}6\right)=\sin\dfrac\pi3$

$\cos^2\dfrac\pi{10}-\sin^2\dfrac\pi{10}=\cos\left(\dfrac{2\pi}{10}\right)=\cos\dfrac\pi5$

The second identity together with the Pythagorean identity, $\sin^2x+\cos^2x=1$ , gives us another equivalent expression:

$\cos^2x-\sin^2x=\cos^2x-(1-\cos^2x)=2\cos^2x-1$

$2\cos^2(0.5)-1=\cos(2\cdot0.5)=\cos1$
