<span>sin(2x)= 2sin(x)cos(x)
can you finish the rest or need more help?
sin(6/5) should be the answer
so we have 2 sin(0.6)cos(0.6)
we know its sin (2x) identity
x=0.6
so its sin(2*0.6)</span>
Answer: 226.76
Step-by-step explanation: A=C^{2}/4π
C^{2} = 2,870. 82
4π = 12.66
2,870.82/12.66 = 226.76
(Make sure to include your units.)
10 1/2 = 10.5
20 * 10.5 = 210
20 * 11.25 = 225
225 - 210 = 15
answer: Caroline would make $15 profit
Because the prices are different, you need to use two variables, one for each price.
Let the price for the plain one be X and the price for the printed one be Y.
You would multiply the number of each shirt by the variable:
3 plain would be 3X and 2 printed would be 2Y.
You then need to add those together to get the total cost:
Total cost = 3X + 2Y
A square has 4 sides.
If the perimeter around the square is 12cm, then you do 12 ÷ 4, which is 3.
Each side is 3cm long.
