This is the concept of exponential functions; The statements that are correct about the exponential decay functions are:
1. The domain is all real number
4. The base must be less than 1 and greater than 0
5. The function has a constant multiplicative rate of change

Hello from MrBillDoesMath!
Answer:
Choice D, x = +\ sqrt(121)
Discussion:
x^2 = 121 => take square roots of both sides
x = +\- sqrt(121) => as sqrt(121) = +\- 11
x = +\- 11
The closest answer is D as it includes both values of x, unlike choices A and B which include a single value of the square root
Thank you,
MrB
You're answer is correct. If you round up and estimate to the whole number it would be 9 yards. If you add the total it would 10 yards. You have at least 6 yards so a & b would be out. Then 3/4 three times would be greater then 1/2. So c would be out as well.
I would assume that the answer would be x=40 degrees, if not that then x=50 degrees but I would answer with x=40 degrees.
