We are learning about circles in geometry so if someone knows geometry, can they try to solve it? Also try your best to explain, thank you ​

Asocial networking site currently has 400,000 active members, and that figure is predicted to increase by 32% each year. the following expression represents the number of active members on the site after t years.

Aquantity with an initial value of 3900 decays exponentially at a rate of 35% every hour. what is the value of the quantity after 0.5 days, to the nearest hundredth?

25 ! the line of best fit is h = 5a + 86. predict the height at age 16. show your work.
