Answer:
11 years
Step-by-step explanation:
14 divide 2=7
7 divide 2=3.5
3.5 divide 2 = 175 subtract 1 extra year to turn to 200. So the answer is 11.
Answer:
For the given expression, x = 12.
Step-by-step explanation:
Here, in the given expression:
6 over x equals 4 over 8.
Now, 6 over x = 
and 4 over 8 = 
So, here 
⇒ x = 12
Hence, for the given expression, x = 12.

Answer:
see attached
Step-by-step explanation:
The equation is in the form ...
4p(y -k) = (x -h)^2 . . . . . (h, k) is the vertex; p is the focus-vertex distance
Comparing this to your equation, we see ...
p = 4, (h, k) = (3, 4)
p > 0, so the parabola opens upward. The vertex is on the axis of symmetry. That axis has the equation x=x-coordinate of vertex. This tells you ...
vertex: (3, 4)
axis of symmetry: x = 3
focus: (3, 8) . . . . . 4 units up from vertex
directrix: y = 0 . . . horizontal line 4 units down from vertex
Answer:

Step-by-step explanation:
-We can use the exponential decay function to estimate the size after 13 years:

Where:
is the size after t years, t is the time, r is the rate of decay and
the original size.
#We substitute and calculate as:

Hence, the forest covers
after 13 years.
