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
Answer:
Step-by-step explanation:
well the values for x are from -2 to ∞
so we can write it as
A. 8 feet * 0.9 = distance after first bounce
h(n) = 8 * 0.9^n
b. 8 * 0.9^14 = 1.83 feet to 2 d.p.
1.83 * 12 = 21.96 inches
• measure of the side: s = 3 in
You can find the height h by this formula:
s · √3
h = ————
2
3 · √3
h = ————
2
3√3
h = ———— in (exact value)
2
Using √3 ≈ 1.73,
3 · 1.73
h ≈ —————
2
5.19
h ≈ ————
2
h ≈ 2.60 in (approximate value)
I hope this helps. =)
