Answer:
2205
Step-by-step explanation:
The area is multiplied by 1-4.75% = 0.9525 each year. After 7 years, the multiplication factor is 0.9525^7. Then the area is predicted to be ...
3100 × 0.9525^7 ≈ 2205
Answer:
Step-by-step explanation:
This can be represented as exponential decreasing function.
y = a(1 - r)t
a = starting amount
r = rate
t = years
y = 1600(1 - .0725)15
= 1600(.9275)15
= 1600(.32337673)
= 517.40
In 15 years, the forest will shrink in size to 517.40 km2

Answer:
y=3
Step-by-step explanation:
y=mx+b where m = slope and b=y-intercept
slope: 0, y-intercept: 3
y=(0)x + 3
y=3
Uhhhhh yes.?
love that for u
Width = X
Length = X + 15
Perimeter of a Rectangle = 2W + 2L
2(X) + 2(X + 15)
2X + 2X + 30
4X + 30
Answer = 4X + 30

Answer:
2000
Step-by-step explanation:
Expanded form:
80 × (20 + 5)
Partial products:
80 × 20 = 1600
80 × 5 = 400
Sum of partial products: 1600 + 400 = 2000.
