Problem 1 - Lillies • First correct answer - yell it out • A pond has a lilly growing in it that doubles in size every day. It takes 30 days to cover the pond. On what day will it cover a quarter of the pond?
Problem 2 - Pay it forward • See video • Question: The USA has a population of 307,006,550. If it takes each person a week to ‘pay it forward’, how long before everyone in the USA has something good done for them?
John McClane is having (another) bad day • See video • What’s the phone number the need (shhhh, don’t let on...)?
Let’s get some help from Sesame Street • See video
Back to John and Zeus... • As I was going to St Ives • I met a man with seven wives. • Every wife had seven sacks, • Every sack had seven cats, • Every cat had seven kits. • Kits, cats, sacks and wives, • How many were going to St Ives? • What was that phone number?
Exponential equations • Exponential equations take the form of: • Find what each variable does algebraically and graphically, and make a general statement for each - final product on A3 for display ( ‘a’ will..., ‘b’ controls how... ‘c’ controls...... etc ) • And make sure it says what happens if to the graph when… • a > 0, b > 1 a > 0, 0 < b < 1 • a < 0, b > 1 a < 0, 0 < b < 1
Index laws • Prove ‘em
