The equation b = 500. (1.05) gives the balance of a bank account t years since the
ccount was opened. The graph shows the annual account balance for 10 years.
a. What is the average annual rate of
change for the bank account?
b. Is the average rate of change a good
measure of how the bank account
varies? Explain your reasoning.

Which is the product of 58 and 1,000? a. 0.058 b. 5,800 c. 58,000 d. 580,000

Look at this pattern ; 1,4,9, number 10000 belongs in this pattern . what’s the place of this number?

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
