Answer:
Step-by-step explanation:
If that number is greater than 1, that means that the exponential equation represents growth. If that number is less than 1 but greater than 0, that means that the exponential equation represents decay. Since ours is greater than 1, our equation is exponential growth. It means that the perent of animals adopted grows at a rate of 145% per year, with a starting number of 28 animals in the first year.
Hello!
You can only add variables with the same base and exponent
8u^3 + 4u^3 = 12u^3
8u^2 + 0 = 8u^2
0 + -6u = -6u
6 + 3 = 9
Put the sums together
12u^3 + 8u^2 - 6u + 9
The answer is

Hope this helps!
Answer:
Height = 5.6cm
Step-by-step explanation:
Area = 1/2bh
b = 10cm, area = 28cm^2
:- 28 = 1/2 × (10)h
28 = 5h
h = 28/5
h = 5.6cm
Answer:
84
Step-by-step explanation:
The mean is calculated as
mean =
, then
= 21 ( multiply both sides by 4 )
sum = 84
