Answer:
The value of A is also 40
Step-by-step explanation:
My reasoning why is because its the same for each.
To reflect it across the y-axis means to go from quadrant 2 to 1.
In quadrant 1, both x and y are positive.
So, (-6,6) becomes (6,6).
Answer:
34.785 units²
Step-by-step explanation:
The area of each triangular section of the hexagon is ...
... A = (1/2)sin(60°)·8²
There are 6 such sections, so their total area (the area of the hexagon) is ...
... 6A = 6·(1/2)·sin(60°)·8² = 3sin(60°)·8² . . . . . hexagon area
The area of the circumscribing circle is ...
... A = πr² = π·8²
The shaded area is the difference between the area of the circle and the area of the hexagon:
... shaded area = π·8² -3sin(60°)·8² = 64(π -3sin(60°))
... shaded area ≈ 34.785 units²
Answer:
x =35.29
Step-by-step explanation:
If it is reduced by 15%, you are paying 100-15 = 85%
The original price is x
x* 85% = 30
x *.85 = 30
Divide each side by x
x = 30/.85
x =35.29
