For P(t) = 920*1.06^(2t), the current population is 920, the percentage growth rate is 6% semiannually, and the population in 4 years will be 920*1.06^8 = 1466.
Selection B is appropriate.
_____
The 2 in the exponent means the growth factor 1.06 is applied twice for each increment of t, that is, twice in 1 year (semiannually).
Answer: x ≥ -4 (in words: x is greater than or equal to -4)
Step-by-step explanation:
The number line shows all values greater than -4 being shaded in, meaning that x can be any of them. In addition, the point at -4 itself is shaded in, showing that it is also a possible value for x.
I think it’s right, sorry if I’m wrong...
The square root of 5 is the positive real number that, when multiplied by itself, gives the prime number 5. It is more precisely called the principal square root of 5, to distinguish it from the negative number with the same property. This number appears in the fractional expression for the golden ratio. It can be denoted in surd form as:

It is an irrational algebraic number.[1] The first sixty significant digits of its decimal expansion are:
2.23606797749978969640917366873127623544061835961152572427089… (sequence A002163 in the OEIS).
which can be rounded down to 2.236 to within 99.99% accuracy. The approximation
