Answer: B- A(n) = P+(n-1)i•P, where n is a positive integer
Step-by-step explanation:
The circumference is πd, and the diameter is 10, so the circumference is 10π. All sides of a square are equal, so the length of each side is 10π/4, which is 2.5π.
The length of each side of the square is 2.5π
9/200. divide 45 and 1000 both by 5 to reduce it.
Answer:
I got 17.7°
Step-by-step explanation:
Since a complimentary angle adds up to 90 degrees, this would be the right answer... does it require a degree symbol?
Answer: B
Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with 
-3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format: 
+bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be
(-(-3)±√(-3²-4(4)(-9)/2(4).
