Answer:
2 times
Step-by-step explanation:
the length and breadth of the parallelogram will be l and b, respectively.
Then, perimeter = 2(1 + b) [∵ perimeter of parallelogram = 2 x (length + breadth)]
If both sides are increased twice, then new length and breadth will be 21 and 2b, respectively.
Now, new perimeter = 2(21 + 2b) = 2 x 2(l + b) = 2 times of original perimeter.
the perimeter of parallelogram will be increased 2 times.

Answer:
1). Fold reflection symmetries = 5
2). Order of rotational symmetries = 10
3). Smallest angle of rotational symmetry = 36°
Step-by-step explanation:
A decagon has number of fold reflection symmetries = 5
[Fold reflection symmetries are the lines by which we can fold the shape into half]
Order of rotational symmetry of a decagon = 10
[Order of rotational symmetry means number of rotations by which the polygon maps itself in a complete rotation of 360°]
Smallest angle of rotational symmetry for a decagon
= 
= 
= 36°
Answer:
A. YES
B. NO
C. YES
Step-by-step explanation:
A. 100% = $24.30
24.3 x 0.85 = 85% = $20.66 (yes)
B. 100% = $55.80
55.8 x 0.85 = 85% = $47.43 (no)
C. 100% = $66.50
66.5 x 0.85 = 85% = $56.53 (yes)
Answer:
f^-1 (x) = 1/2x -5/2
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y = 2x+5
Exchange x and y
x = 2y+5
Solve for y
Subtract 5 from each
x-5 = 2y+5-5
x-5 = 2y
Divide by 2
(x-5)/2 = 2y/2
1/2x - 5/2 = y
f^-1 (x) = 1/2x -5/2
