<u>Factoring</u><u> -1 out of negative numbers</u><u>:</u>
11) (-6) • (3)= (-1 • 6) • 3= -1 • 6 • 3= -18
-6 is the negative number here and factoring out -1 from -6 will give us -1(6). In the second last step, multiply 6 and 3 together then multiply the product by -1.
-1(6 ×3)= -1(18)= -18
12) (-4) • (-8)= (-1 • 4) • (-1 • 8)= 1 • 4 • 8= 32
Multiplying 2 negative numbers will give us a positive number. The 3rd step is 1 as (-1)(-1)= 1.
13) (-9) • (-5)= (-1 • 9) • (-1 • 5)= 1 • 9 • 5= 45
14) (2) • (-8)= 2 • (-1 • 8)= -1 • 2 • 8= -16
Negative numbers are numbers with a negative sign and are numbers less than zero. Factoring -1 out of negative numbers will leave us with the positive number.
Answer:
Hour 3
4 * 2 = 8
Hour 4
8 * 2 = 16
Hour 6
32 * 2 = 64
Hour 7
64 * 2 = 128
Hour 12
2048 * 2 = 4096
Step-by-step explanation:
We are told that initially there is a bacterium that doubles every hour, so let's calculate what happens in the first 12 hours every hour.
Hour 0
one
Hour 1
1 * 2 = 2
Hour 2
2 * 2 = 4
Hour 3
4 * 2 = 8
Hour 4
8 * 2 = 16
Hour 5
16 * 2 = 32
Hour 6
32 * 2 = 64
Hour 7
64 * 2 = 128
Hour 8
128 * 2 = 256
Hour 9
256 * 2 = 512
Hour 10
512 * 2 = 1024
Hour 11
1024 * 2 = 2048
Hour 12
2048 * 2 = 4096
We can deduce that the growth of the bacteria is:
2 ^ n
where n is the # of time that has passed
