Precalculus PLEASE HELP ME right answers only check all please

Alex_Xolod [135]

Given :

$cos(x)cos(\frac{\pi }{7}) + sin(x)sin(\frac{\pi }{7})=-\frac{\sqrt{2}}{2}$

We know the identity

$cos(x)cos(y) + sin(x)sin(y)=cos(x-y)$

We use this property to simplify the left hand side

So $cos(x)cos(\frac{\pi }{7}) + sin(x)sin(\frac{\pi }{7})=cos(x - \frac{\pi }{7})$

$cos(x - \frac{\pi }{7}) =-\frac{\sqrt{2}}{2})$

we know ,

when $cos(x) =-\frac{\sqrt{2}}{2})$ then

$x = \frac{3\pi }{4} , \frac{5\pi }{4}$

For $cos(x - \frac{\pi }{7}) =-\frac{\sqrt{2}}{2})$

$x - \frac{\pi }{7}= \frac{3\pi }{4} and x - \frac{\pi }{7}= \frac{5\pi }{4}$

Add $\frac{\pi }{7}$ on both sides

$x= \frac{3\pi }{4} + \frac{\pi }{7} and x= \frac{5\pi }{4} +\frac{\pi }{7}$

Finally we add 2npi for general solution

So options C and D are correct

Pumpkins at a local farm sell for $.49 per pound. Jim Ring spent $73.50. How many pounds of pumpkins were purchased?

Leona [35]

Number of pounds purchased multiplied by price per pound equals the total $ spent.

x= # pumpkin pounds purchased
0.49x=$73.50
Divide both sides by 0.49
x=150 pumpkin pounds purchased

Hope this helps! :)
