Given:
Octagon-shaped patio
Side length = 24ft
apothem length = 60ft
Area of a regular octagon = 2 * a² * (1 + √2)
a = side length
A = 2 * (24ft)² * (1 + √2)
A = 2 * 576ft² * (1 + 1.414)
A = 2 * 576ft² * 2.414
A = 2,780.93 ft²
After a year the
population will be 98.6% (100% - 1.4%) 98.6% as a decimal is 0.986 ... so after
1 year it will be: <span>
3800 x 0.986
after 2 years it will be:
3800 x 0.986 x 0.986...
after 3 years: 3800 x (0.986)^3
<span>in 2018. And after 4 years it will be 3800 x (0.986)^4 =
which is 3591.62724 or 3592</span></span>
Answer:
8
Step-by-step explanation:
The new height is 24
The original height is 3
24/3 is 8
The scale factor is 8
Here, ∠WVX = ∠WZY
& ∠W = ∠W [ Reflexive Property ]
Triangles have the constant sum, so they would be: equal.
WVX + WXV + W = W + WZY + WYZ
WXY = WYZ [ ∠WVX = ∠WZY ]
Now, As all the angles are equal, we conclude:
ΔXVW ≈ ΔYZW [ By ASA Postulate ]
Hope this helps!
