Answer:
B-a population growth of 3% each year
Step-by-step explanation:
The 1.03 would mean that the exponential function is increasing by 3% every year because it is 0.03 units above 1.

Answer: x^2 - 14x + 49
Explanation:
1) Divide the coefficient of x by 2:
14 / 2 = 7
2) so you have to add 7^2 = 49
x^2 - 14x + 49
3) that trinomial is equivalent to:
=> (x - 7)^2
4) prove that using the formula (a - b)^2 = a^2 - 2ab + b^2
(x - 7)^2 = x^2 - 14x + 49
Then you have to add 49 to complete the square. and form a perfect square trinomial.
Okay lets go down the list. It's not right since 20²+99²=10201 √10201=101 and you said a is wrong it's have to be B. obtuse
