<span>Find the exact value of sec(-4π/3). Note that one full rotation, clockwise, would be -2pi. We have to determine the Quadrant in which this angle -4pi/3 lies. Think of this as 4(-pi/3), or 4(-60 degrees). Starting at the positive x-axis and rotating clockwise, we reach -60, -120, -180 and -240 degrees. This is in Q III. The ray representing -240 has adj side = -1 and opp side = to sqrt(3).
Using the Pyth. Theorem to find the length of the hypo, we get hyp = 2.
Thus, the secant of this angle in QIII is hyp / adj, or 2 / sqrt(3) (answer). This could also be written as (2/3)sqrt(3).

Answer:
<h2>-4a²b³ (-6+ 7a³)</h2><h2 />
Step-by-step explanation:
24a²b³ - 28a⁵b³
apply exponential rule:
24a²b³ - 28a²a³b³
re-write 24 as 6*4 and -28 as 7*4
6*4a²b³ + 7*4a²a³b³
factor common terms
-4a²b³ (-6+ 7a³)
I hope this helps you
3x-25=6x-80
6x-3x=80-25
3x=55
x =55/3
The answer is
y= - x-9/3 I believe.
1- Subtract 9 from both sides.
-3y = x - 9
2- Divide both sides by -3
y = - x-9/3
