Answer: 
Step-by-step explanation:
When we consider Area under arc AC is is representing a quarter as ADBC is a square, 
.
Area of quadrant = 
here r= 8 cm
Area under Arc AC= 
Area of white region ABC = Area of square ADBC - Area under Arc AC
![=8^2-16\pi\ \ [\text{Area of square} = sides^2]\\\\= 64-16\pi\ \ =16(4-\pi)\ cm^2](https://tex.z-dn.net/?f=%3D8%5E2-16%5Cpi%5C%20%5C%20%20%20%20%20%5B%5Ctext%7BArea%20of%20square%7D%20%3D%20sides%5E2%5D%5C%5C%5C%5C%3D%2064-16%5Cpi%5C%20%5C%20%20%3D16%284-%5Cpi%29%5C%20cm%5E2)
Similarly , Area of white region ADC = 
Area of shaded region = Area of square - Area of white region ABC - Area of white region ADC
Area of shaded region =
Length of arc AC = 
Perimeter of shaded region = 2(AC) = 
Answer:
Option c. (x, y) → (y , x)
Step-by-step explanation:
we know that
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places
Remember that each point of a reflected image is the same distance from the line of reflection as the corresponding point of the original figure
so
The rule of the reflection across the line y=x is
(x,y) → (y,x)

Answer:
Three cubes
Step-by-step explanation:
The cubes have to be indistinguishable and all orientations of one cube are also have to be indistinguishable.
All ways of connecting two cubes result in the same shape. So answer is larger than two.
After connecting two cubes, there are ten faces where the third cube can be attached, and two faces which are connected, accounting for all 12 faces of two cubes.
Of the 10 exposed faces, exactly two are on opposite ends, both leading to the same straight line figure. The other 8 faces all lead to an L shape, and all L shapes can be rotated to be identical.
Hence, three cubes can only make a straight shape or an angled shape.
Four cubes can make a straight shape, a L shape, a Γ shape (but flipping it over through 3 dimensions makes L and Γ identical), a T shape, and a square shape. That is either four or five different objects depending on if they can be lifted from the table. Anyway, it is more than two.
20 percent of the discount minus 5 percent sales tax equals to 15 percent.
know calculate the 15 percentage out of 78,12 so x on 78,12 equals to 20 on 100 so 78,12 equals to 100 percent and x equals to 15 percent so 78,12 times 15 divided by 100 is 15 percent or the number you found discount and and sales tax combined know you substact 15 percent out of your original price.
