Answer:
See graph below.
Step-by-step explanation:
5 - 3lp + 4l ≤ -10
Subtract 5 from both sides.
-3lp + 4l ≤ -15
Divide both sides by -3.
|p + 4| ≤ 5
p + 4 ≤ -5 or p + 4 ≥ 5
Answer is option C. p + 4 ≥ 5 or p + 4 ≤ -5
Had to do a bit of guesswork to figure out what you're asking here. If you're given the 2 angles pi/4 and pi/6, you can find any trig function of either angle.
The sine of pi/4 is 1 / sqrt(2); the cosine is the same.
The cosine of pi/6 is sqrt(3) / 2; the sine of pi/6 is 1/2.
If this isn't quite what you were looking for, try paraphrasing your question to make it clearer.
1/4 is 25% or 0.25
1/5 is 20% or 0.20
So the difference between the two is 5%, 0.05, or 1/20.
