Answer:
C
Step-by-step explanation:
The difference formula for cosine is
cos(x - y) = cosxcosy + sinxsiny
Consider
cos75 = cos(120 - 45)°, then
cos(120 - 45)°
= cos120°cos45° + sin120°sin45° → C
Answer:
0.75m/s
Step-by-step explanation:
<em>Speed formula: ⇒ 
</em>
<em>Divide by the numbers from left to right.</em>
<em>S=18</em>
<em>T=24</em>
<em>18/24=0.75</em>
<em>0.75m/s is the correct answer.</em>
<em>I hope this helps you, and have a wonderful day!</em>
20% & DiscountRUs
DiscountRUs offers 40% off while the other offers 1/5 off which is 20% off.
The difference between 40 and 20 is obviously 20.
start with elimination. 8 x 8 is only 64 so C and D dont make sense. The are of the circle is pi(r)². so the radius is 4 squared then multiply by pi and devide by 5 to get the 5 equal parts. So B 10.
16 because two negatives numbers equal a possitive so 16
