I know the equation is 1/cos
but is it negative sqrt(3)/2 or positive?
or is it negative 1/2 or positive?
This makes the reference angle π/6 or 30º which gives cos 30º=√3/2 or a sec value of 2/√3=2√3/3
sec(-5pi/6)=-2√3/3
Answer:
$408
Step-by-step explanation:
It’s very simple. Since gets 12 dollars every week, multiply the number of weeks and how much money she gets. Plus the amount she already had.
32 x 12 = 384
384 + 24 = 408
