Marie posted a dance video online that received 25,000 views today. However, the popularity of her video has peaked; going forward, it will get 40% fewer views each day than the day before. Which equation can Marie use to find t, the number of days until her video is viewed only 5,400 times in a day?

The equation modelling this growth is . Use the method of taking logs to solve this equation for t, giving your answer correct to the nearest day. (Your answer should be a number, without units)

Scientists are studying a sample of radioactive material. The amount left, in grams, after t days can be modeled by the function N(t)=a(b)t, where a and b are constants. This table shows two values of the function.t N(t)1 58.52 52.65Find an expression for N(t). Write your answer in the form N(t)=a(b)t, where a and b are integers or decimals. Do not round.

A man had 432 watches. He sells 1 watch everyday. The algebraic expression to show that the number of watches he would be left with after 't' weeks is?

Liz listens to audiobooks for 10 minutes per day as she commutes to work.Let d represent the number of days Liz has commuted and m represent the total number of minutes she has spent on audiobooks.This relationship can also be shown in a table. Complete the equation that represents the relationship between d and m.d m5 506 607 708 80m=
