Answer:
Figure D. (A)
When you flip the figure across like a mirror, it remains the same shape as the other side. An easy way to determine this is by cutting a line down the middle.
Reflectional symmetry states that if there exists at least one line that divides a figure into two halves such that one-half is the mirror image of the other half.

Answer:
2.225
Step-by-step explanation:
To find how long the object will be in the air, we just need to find the time when the object reaches the ground, that is, f(t) = 0
So, we have that:
0 = −16t2+32t+8
2t2-4t-1 = 0
Using Bhaskara's formula:
Delta = b2 - 4ac = 16 + 8 = 24
sqrt(Delta) = 4.899
t = (-b + sqrt(Delta)) / 2a
t = (4 + 4.899) / 4
t = 2.2248
Rounding to nearest hundredth, we have t = 2.225

Answer:
C $1187
Step-by-step explanation:
diameter = 12ft
radius = 6 ft
area = πr²
= 3.14×6×6
= 113.04 ft²
paving stones is $10.5 per ft²
paving stones cost = 113.04×10.5 = 1186.92
; the nearest dollar do the paving stones cost is $1187
