Answer: y= 1200 (1.025)^t
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population
r = growing rate (decimal form)
t= years
A = population after t years
Replacing with the values given:
1200= 1200 (1+ 2.5/100)^5
1200= 1200 (1+ 0.025)^5
1200= 1200 (1.025)^5
For the number of rabbits, y, at the end of t years
y= 1200 (1.025)^t

Answer:
The length of the rectangle is 
and width is 
.
Step-by-step explanation:
The area of the green zone is 
and the area of the purple zone is 
.
So, the total shaded zone is a rectangle having area = 
.
Now, factorizing the area expression we get, area = 
.
Therefore, we can say the length of the rectangle is and width is . (Answer)

Answer: B) 6</h3>
===============================================
Explanation:
Add the equations by adding the terms straight down.
The x terms add to x+x = 2x.
The y terms add to y+(-y) = y-y = 0y = 0, so the y terms go away
The constants add to 5+7 = 12
The z terms add to -z+z = 0z = 0 and those go away as well
After all that adding, we have 2x = 12 which solves to x = 6 after dividing both sides by 2.
This ones a bit tricky but the answer is A
Answer:
D
Step-by-step explanation:
first find the perimeter of both triangles
Original perimeter: 72 in
scaled perimeter: 24 in
A is wrong since the scaled perimeter is actually smaller.
B is wrong because its not 6 times smaller
C is wrong since it's not 1/9 of the original
D is correct since the scaled is a 1/3 of the original perimeter (72*1/3 = 24)
