Given the geometric sequence where a1 = 4 and the common ratio is 3, what is the domain for n?

all integers where n ≥ 1

all integers where > 1

all integers where n ≥ 4

all real numbers
for this its always greater than one right? for every type of these things?

also given the arithmetic sequence an = 4 − 3(n − 1), what is the domain for n?

all integers where n ≥ 1

all integers where n > 1

all integers where n ≤ 4

all integers where n ≥ 4

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases

You were told that the amount of time lapsed between consecutive trades on the new york stock exchange followed a normal distribution with a mean of 15 seconds. you were also told that the probability that the time lapsed between two consecutive trades to fall between 16 to 17 seconds was 13%. the probability that the time lapsed between two consecutive trades would fall below 13 seconds was 7%. what is the probability that the time lapsed between two consecutive trades will be between 14 and 15 seconds?

Gabriel determined that his total cost would be represented by 2.5x + 2y – 2. his sister states that the expression should be x + x + 0.5x + y + y – 2. who is correct? explain.
