Answer:
Below
Step-by-step explanation:
Let's prove that cos^2(O) = 1+ cos(2O)/2
We khow that cos(2O) = 2 cos^2-1
● cos(2O) = 2 cos^2-1
Add one to both sides:
● cos(2O) +1 = 2 cos^2-1+1
● cos(2O) +1 = 2 cos ^2
Divide both sides by 2
● [cos(2O)+1]/2 = cos^2

Answer:
7.81 u
Step-by-step explanation:
<u>Given :- </u>
- Two points (3,3) and (-2,-3) is given to us.
And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,
D = √{(x2-x1)² + (y2-y1)²}
D =√[ (3+2)² +(-3-3)²]
D =√[ 5² +6²]
D =√[ 25 +36]
D = 61
D = 7.81
<h3>Hence the distance between the two points is 7.81 units .</h3>
Decimal: Divide 16 by 25: 0.64
Percent: move the decimal 2 places to the left: 64, then add a percent sign: 64%
