Answer:
Option (D).
Step-by-step explanation:
Initial population of the deer
= 4800
Decrease in the population of the deer after every 8 years = ![\frac{1}{2}\times (\text{Initial population})](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%28%5Ctext%7BInitial%20population%7D%29)
Decrease in population is an exponential process, so the expression representing population will be,
![P_{t}=P_{0}(1-r)^x](https://tex.z-dn.net/?f=P_%7Bt%7D%3DP_%7B0%7D%281-r%29%5Ex)
Where
is the population after 'x' slots of 8 years.
r = fraction of decrease in the population
x = ![\frac{\text{Number of years}}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BNumber%20of%20years%7D%7D%7B8%7D)
By substituting the values of r and x in the expression,
![P_{t}=P_{0}(1-\frac{1}{2})^{\frac{t}{8}}](https://tex.z-dn.net/?f=P_%7Bt%7D%3DP_%7B0%7D%281-%5Cfrac%7B1%7D%7B2%7D%29%5E%7B%5Cfrac%7Bt%7D%7B8%7D%7D)
![P_{t}=4800(\frac{1}{2})^{\frac{t}{8}}](https://tex.z-dn.net/?f=P_%7Bt%7D%3D4800%28%5Cfrac%7B1%7D%7B2%7D%29%5E%7B%5Cfrac%7Bt%7D%7B8%7D%7D)
Therefore, Sylvia should do few corrections in her expression.
(8) should be replaced by (
) and
should be replaced by
.
Option D. will be the answer.
11/12 for the first one and 1/3 on the second. I’m 100% sure but I’m sorry if it’s wrong. Have a great day!
Thas is wrong, it isn't D!!!! its A
Answer:
1/25
Step-by-step explanation:
= 5^4/5^6
= 1/5^6-4
= 1/5^2
= 1/25
hope it helps!
Answer:
translation
Step-by-step explanation:
because a reflection across the x-axis is not right, and neither is across the y-axis. The triangle was also not rotated 90 degrees. It was translated 8 units to the right and 4 units up.
