9. Given A = {1, 2, 3, 4, 5, 6, 7, 8, 9} and B = {2, 4, 6, 8}, what is A∪B?
PtichkaEL [24]
A union B is the set containing all elements in set A and set B there for A union B is the set {1 2 3 4 5 6 7 8 9}
There's literally unlimited answers but here are some simple ones.
5 x 11 = 55
55 = 55
55 > 54
1 < 55
3 x 2 < 55
Answer:
The height of the tree in 2020 was of 19.63 feet.
Step-by-step explanation:
Exponential equation for growth:
The exponential equation for the growth of an amount has the following format:

In which H(t) is the amount after t years, H(0) is the initial amount and r is the growth rate, as a decimal.
A 4 foot tree was planted in 2012 outside a high school.
This means that 
The tree grew continuously by 22% each year from that point.
This means that 
Find out what the height of the tree was in 2020.
2020 is 2020 - 2012 = 8 years after 2012, so this is H(8).




The height of the tree in 2020 was of 19.63 feet.
