THE ANSWER IS D
YOU HAVE AT TIME ZERO 10 BACTERIA,
AFTER 15 SEC YOU HAVE 20 BACT
AFTER 30 SEC THE NUMBER DOUBLES SO YOU HAVE 40 BACT
AFTER 45 SEC YOU YOU HAVE 80
AND SO ON, AFTER 120 SEC YOU HAVE 2560 BACT
Answer:
(-4,-4)min, x-intercepts (-2,0) (-6,0), y-intercept (0,2)
Answer:
Step-by-step explanation:
<u> </u><u>{x | x ≤ 4.5} </u><u> is another way to represent this </u><u>solution set.</u>
- A set is open if every point in is an interior point. A set is closed if it contains all of its boundary points.
What is open set example?
- An open subset of R is a subset E of R such that for every x in E there exists ϵ > 0 such that Bϵ(x) is contained in E.
- For example, the open interval (2,5) is an open set. Any open interval is an open set. Both R and the empty set are open.
What is an example of a closed set?
- The simplest example of a closed set is a closed interval of the real line [a,b].
- Any closed interval of the real numbers contains its boundary points by definition and is, therefore, a closed set.
- The closed interval [1,4] contains the limit points 1 and 4 so it is a closed set.
Then number-line shows a closed dot at 4.5. This shows that x is a number that is less than or equal to 4.5.
