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.
Answer:
Median: 8
Mode: 7
I believe this is correct.
Answer:
- {0, 11, 22, 33, 44, 55, 66, 77, 88, 99, 110}
Step-by-step explanation:
<u>The relationship is:</u>
y - is the money received for the coupons, x- is the number of coupons
<u>x is the domain and it includes whole numbers from 0 to 11:</u>
- x = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
<u>y is the range and it includes the set of numbers:</u>
- y = {0, 11, 22, 33, 44, 55, 66, 77, 88, 99, 110}
Answer:
D
Step-by-step explanation:
To convert from polar to rectangular form
• x = rcosΘ , y = rsinΘ
• r =
⇒ r² = x² + y²
Given
r = 8cosΘ
r = 8 ×
( multiply both sides by r )
r² = 8x, hence
x² + y² = 8x ⇒ D
