Colby and jaquan are growing bacteria in an experiment in a laboratory. Colby starts with 50 bacteria in his culture and the num ber of bacteria doubles every 2 hours. Jaquan starts with 80 of a different type of bacteria that doubles every 3 hours.
Let x equal number of days.
Colby’s experiment follows the model:
1) y=50*2^x
2) y=50*2^8x
3) y=50*2^12x
Jaquan’s experiment follows the model:
1) y=80*2x
2) y=80*2^8x
3) y=80*2^12x

1 answer:
Answer:
3) y = 50 * 2¹²ˣ
2) y = 80 * 2⁸ˣ
Step-by-step explanation:
1 day = 24 hours
Number of 2-hour periods in 1 day = 24 ÷ 2 = 12
Number of 3-hour periods in 1 day = 24 ÷ 3 = 8
Colby's experiment:
y = 50 * 2¹²ˣ
Jaquan's experiment:
y = 80 * 2⁸ˣ

Answer:
The numbers 1 to 12 must be placed in the circles of the star shown on the right. The sums of the numbers in each row, and the sum of the numbers in the six outer circles of the star, must be equal to 26. Arrange the numbers accordingly.
Gotta add a picture to show us what you want us to do.
I think the answer is 17 because the pattern adds 4 then takes away 1 so 14-1=13 13+4=17
