Answer: 15 Combinations
Step-by-step explanation: 5x3=15
Answer:
- 4 < x ≤ 5
Step-by-step explanation:
There is an open circle at - 4 indicating that x cannot equal - 4
There is a closed circle at 5 indicating that x can equal 5
The line connects the 2 endpoints and is
- 4 < x ≤ 5
Since the boxes are identical we can say that the total height is 3 times that of a single box:
Total = 3 * 56.4cm
Total = 169.2cm
Step-by-step explanation:
for part a
initial means starting point and starting point is always 0
so the question means number of thousands of bacteria in 0 hours, your n being the number of hours. so in part a u will simply just put 0 as n in equation
2^(0+3)
2³=8 thousands of bacteria
in part b
2^(n+3) means total number of bacteria
2^(n-1) is number of groups
its asking for number of bacteria in each group
so u will simply divide number of bacteria by groups
its like u have 30 candies and there are 5 groups and they ask u to find number of candies in each group so u simply divide 30 by 5
so 2^(n+3)/2^(n-1)
base is same so powers will subtract since there is division sign
2^(n+3-(n-1))
2^(n+3-n+1)
2^(3+1)
2^4= 16 thousands of bacteria in each group
