Solution:
As we know reference angle is smallest angle between terminal side and X axis.
As cosine 45 ° is always positive in first and fourth quadrant.
i.e CosФ, Cos (-Ф) or Cos(2π - Ф) have same value.
As, Cos 45°, Cos (-45°) or Cos ( 360° - 45°)= Cos 315°are same.
So, Angles that share the same Cosine value as Cos 45° have same terminal sides will be in Quadrant IV having value Either Cos (-45°) or Cos (315°).
Also, Cos 45° = Sin 45° or Sin 135° i.e terminal side in first Quadrant or second Quadrant.
Answer:
q > 4
Step-by-step explanation:
Step 1: Write inequality
7 < 4q - 9
Step 2: Solve for <em>q</em>
<u>Add 9 to both sides:</u> 16 < 4q
<u>Divide both sides by 4:</u> 4 < q
Here, we can see that any number greater than 4 will work. So even 23573489079357 would work, as long as it is greater than 4.
Answer:
ok so it can either be 0.07x or 1/15x (they are equal)
(both being 1/15th of a cookie per minute)
If I'm not mistaken, x=1 2/3 or 1.66
