Answer:
the answer is
cause sin²x= 2/25
so cos²x would be 1-2/25= 23/25
then cos x is what I wrote as the answer

Answer:
Step-by-step explanation:
Simplifying
2x + 4y = 13
Solving
2x + 4y = 13
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
2x + 4y + -4y = 13 + -4y
Combine like terms: 4y + -4y = 0
2x + 0 = 13 + -4y
2x = 13 + -4y
Divide each side by '2'.
x = 6.5 + -2y
Simplifying
x = 6.5 + -2y

Answer: 26.01 pi
Step-by-step explanation: The formulae to find the area of a circle is pi times the radius squared. So 5.1 times 5.1=26.01. So the answer would be 26.01pi or (using 3.14 for pi) 81.6714
