Answer:
30
Step-by-step explanation:
27, 28, 28, 29, 29, 29, 30, 30, 30, 31, 31, 31, 33, 34
Continuously cross one off from each side and get 30 and 30. The mean of these is 30.
Answer:
9r
Step-by-step explanation:
For direct relations, we can write:
m = kp; k is the constant of proportionality.
5 = 7k
k = 5/7
The constant of variation is 5/7.
Answer:
C. 179 ft²
Step-by-step explanation:
Area of circular path or walkway
= π × (R + r) × width
Where
R= Outer radius
r = Inner Radius
Diameter = 16 feet
Width = 3 feet
Inner Radius = Diameter/2
= 16 feet/2 = 8 feet
Outer Radius = 8 + 3 = 11 ft
Hence:
= π × (11 + 8) × 3
= π × 19 × 3
= 179.07078125 ft²
Approximately = 179 ft²
The area of the circular walkway = 179ft²
Option C is correct.
Hello :
y= -x²-4x-1
y = - (x²+4x+1)
y = - ((x²+4x+4)-4+1)
y = - ((x+2)²-3)
y = -(x+2)²+3 the vertex is A(-2 ; 3)
