The area of the rectangle is 12 square foot because in or to determine the area you need to multiply the length times height.
Answer: 168%
Step-by-step explanation:
to find how much the wolf population increased in 2016 (or the wolf population in 2017) , do 50 * 1.4.
doing this, you get 70. we multiple by 1.4 because 1 includes the original 50 with the .4 being the increase. you could also do 50 * .4 which is 20 and add that to the original if it's easier.
using our new number, we can multiple 70 by 1.2 (or by .2 and add that to 70, your choice) to get 84. we now have 84 in 2018
we now have to see how much it increased total (50-84)
do this by doing 84/50
this is 1.68
to check our work, do 1.68 & 50 and we get 84.
transfer this to percent (move the decimal over two spots), you get 168 percent.

Answer:
The function defining the sequence is;
F(n) = 2.5•3^(n-1)
Step-by-step explanation:
Here, we want to find an expression that defines explicitly what is obtained in the sequence.
Checking the sequence, we can observe that the second term is 3 multiplied by the first term, the 3rd term is 3 multiplied by the second and so on
So what this means is that, the succeeding term is 3 times the preceding term;
Also, we can see that the first term is a factor of all the numbers and this mean that;
Second term = 3 * 2.5
Third term = 9 * 2.5 = 3^2 * 2.5
Fourth term 27 * 2.5 = 3^3 * 2.5
Thus, in function form;
F(1) = 2.5•3^(1-1)
F(2) = 2.5•3^(2-1)
F(3) = 2.5•3^(3-1)
Thus;
F(n) = 2.5•3^(n-1)
