Answer:
Rate of change per hour in the number of bacteria is r=0.28
Step-by-step explanation:
Given : There are 16 bacteria in a beaker and four hours later there are 228 bacteria in the beaker.
To find : What is the rate of change per hour in the number of bacteria.
Solution :
At initial number of bacteria is 16
After 4 hours number of bacteria is 228
Rate of change per hour is given by
where A = total number of bacteria, P = initial number of bacteria, r= rate of change , t= time
Taking log both side,
Therefore, Rate of change per hour in the number of bacteria is r=0.28
Answer:
x ≥ 18
Step-by-step explanation:
Given the inequality statement, 2/3x + 17 ≥ 29,
Subtract both sides by 17:
2/3x + 17 - 17 ≥ 29 - 17
2/3x ≥ 12
Multiply both sides by 3/2 to isolate x:
x ≥ 18
Step-by-step explanation:
a(n) = a ( n - 1) - 17
a(1) = 20
a(2) = a ( 2 - 1) - 17
= a (1) - 17
= 20 - 17
= 3
Now
a(3) = a ( 3 - 1 ) - 17
= a (2) - 17
= 3 - 17
= - 14

Answer:
C
Step-by-step explanation:
It’s convenient that there are only two <em>x</em> values you need to check, -2 and 2. Just insert it to see what <em>y</em> is appropriate.
x = -2: y > 6 + 3 = 9 (and y > -2 + 2 = 0 which is redundant here)
x = 2: y > 2 + 2 = 4 (and y > -6 + 3 = -3 which is redundant here)
So, neither B nor D is in the solution set with 5 < 9 and -5 < 9.
A isn’t in the solution set either with -5 < 4.
C is in the solution set with 5 > 4.
