Let x represent the number of weeks a population of the bacteria increases. Then, we have the number of bacteria is molded by the expression of 900*3^x. By, the given expression and when we assigned a value of x=2. Then we have 900*3² .
Answer:
x = 4.1 cm
Step-by-step explanation:
15.6 / 2 = 7.8
x^2 = 8.8^2 - 7.8^2
x^2 = 77.44 - 60.84
x^2 = 16.6
x = 4.1
Answer:
30 inches
Step-by-step explanation:
Assuming the lengths are measured when B lies between A and C on a line, the segment addition theorem applies:
AC = AB +BC
42 = AB + 12 . . . . . fill in the given numbers
30 = AB . . . . . . . . . subtract 12
The length of AB is 30 inches.
