<span>Answer:
year 0 you get 3 * .25^0 = 3 * 1 = 3
year 2 you get 3 * .25^1 = 3 * .25 = .75
year 3 you get 3 * .25^2 = 3 * .0625 = .1875
the numbers are decreasing year after year so you are talking about decay.
b^x increases as x increases if b is greater than 1.
b^x stays the same as x increases if b is equal to 1.
b^x decreases as x increases if b is greater than 0 and less than 1.
x is assumed to be greater than or equal to 0.</span>

Answer:
1. A = 2x; P = 4x+2. A = 4; P = 10.
2. A = y² +2; P = 4y +2. A = 27; P = 22.
Step-by-step explanation:
1. The area is the sum of the marked areas of each of the tiles:
A = x + x
A = 2x
__
The perimeter is the sum of the outside edge dimensions of the tiles. Working clockwise from the upper left corner, the sum of exposed edge lengths is ...
P = 1 + (x-1) + x + 1 + (x+1) + x
P = 4x +2
__
When x=2, these values become ...
A = 2·2 = 4 . . . . square units
P = 4·2+2 = 10 . . . . units
_____
2. Again, the area is the sum of the marked areas:
A = y² + 1 + 1
A = y² +2
__
The edge dimension of the square y² tile is presumed to be y, so the perimeter (starting from upper left) is ...
P = y +(y-2) +1 +2 +(y+1) +y
P = 4y +2
__
When y=5, these values become ...
A = 5² +2 = 27 . . . . square units
P = 4·5 +2 = 22 . . . . units
In a cyclic quadrilateral, the opposite angles add up to 180 degrees.
Opposite angle to angle A = Angle D.
A + D = 180
64 + D = 180
D = 180 - 64
D = 116°
Option E.
Answer:
y= 5x +12
Step-by-step explanation:
y=mx+b is slope intercept form
m = slope
b = y intercept
