Answer:
(-6, -45)
Step-by-step explanation:
Hello ,
f(-2) = 24/3*(-2) - 2
f(-2) = 24/-6-2
f(-2) = 24/-8
f(-2) = -3 .
Kiera's dance class is 1 hour and 45 minutes long (1:45)
<span>We know that sin^2(x) = 1 - cos^2(x), so
2 - 2 cos^2(x) = 2 + cos(x)
cos(x) + 2 cos^2(x) = 0
One immediate possibility is that cos(x) = 0, in which case x = Pi/2 or
3pi/4. If cos(x) is not zero, then divide both sides by cos(x) to obtain
cos(x) = -1/2
which gives x = 2Pi/3 and x = 4Pi/3.
So your solutions are
Pi/2, 3Pi/4, 2Pi/3, and 4Pi/3
Hope this helps :D</span>
