Answer:
C
Step-by-step explanation:
3, 4 and 5 cant be a right triangle
Answer:
(2n + 1)[(2n + 1) � 1]
(2n + 1)(2n + 1 � 1)
(2n + 1)(2n), or 2n(2n + 1)
2n is an EVEN NUMBER, and adding 1 to an even number creates an ODD number
Therefore, 2n(2n+1)=EVEN NUMBER ODD NUMBER=EVEN NUMBER
Step-by-step explanation:
Answer:
294.5 m²
Step-by-step explanation:
shaded region = area of major sector + area of triangle
central angle of major sector = 360° - 130° = 230°
area of sector = area of circle × fraction of circle
A = π × 11.1² × 
=
≈ 247.3 m²
area of triangle = 0.5 × 11.1 × 11.1 × sin130° ≈ 47.2 m²
shaded area = 247.3 + 47.2 ≈ 294.5 m²
Answer:
1-(r÷7) or r÷7-1
Step-by-step explanation: Quotient is the result of a division problem.
Answer:
A. f(x) = 2x + 1.
Step-by-step explanation:
5 = 2(2) + 1
11 = 2(5) + 1
17= 2(8) + 1
23 = 2(11) + 1
- so it is f(x) = 2x + 1.
